Stopson Italiana supplied Pulse-Jet Filter houses and Soundproofing Equipment for Blower packages in Egypt

No. 2 Air Intake systems with self-cleaning filters, inlet silencers and ducts, acoustic enclosures, discharge silencers, including control system with related inlet silencers recently commissioned at the “Ain-Sokhna Phosphatic Fertilizer Complex” near the Red Sea.

 

The project – recently installed – entails the supply of several components joined together. The main item is represented by a system of n.2 auto-cleaning filters, designed taking into consideration the high presence of dust in the site. In addition to this, n.2 Duct silencers, n.2 Acoustic Enclosures, and n.4 Discharge Silencers complete the project.

These latter are the ideal solution for noise reduction caused by gas pulsation in refrigeration and air conditioning systems.

The multidisciplinary nature of the project has been turned into a challenging research and design work, carried out successfully by the Stopson Italiana engineering team. Indeed each component has been customized in order to be assembled and working in non-ordinary climatic condition. It is also noteworthy that Stopson Italiana has been designed as responsible both for the release of the electro-instrumental parts and the control panels of the system.

The project – of which the installation is underway in these days – consists in the following units:

  • 2 Filter house pulse jet type for a flow of 172189 Nm3/h
  • 2 Inlet and Duct Silencer from filter house to blowers
  • 2 Acoustic Enclosure for blowers
  • 4 Exhaust Silencers on blowers discharge

The acoustic warranty covers 82 dbA SPL, at 1m from each unit supplied.

 

This Sulphuric Acid Plant is a part of a contract that represents half of the total Fertilizers Complex built at Ain Sokhna, which is the biggest complex ever built in the fertilizers sector in Egypt.

The project aims to cover the local market’s fertilizer needs and export surplus production. The cluster includes n.9 major factories with a production capacity of 1m tons/y of phosphate and compound fertilizers, Di-Ammonium Phosphate (DAP) and pure and commercial phosphoric acid. The whole plant has been implemented by three companies specialized in building the largest phosphate fertilizer factories in the world using Italian, Spanish and Chinese technology.

With this recent achievement, Stopson Italiana re-confirm its capability to provide “one-stop-shop option” for complex equipment packages covering the entire range of product related to air inlet and filtration system, soundproofing solutions for either in duct and break-out noise and control system implementation.

Stopson Italiana’s Enclosures soundproof the new Grastim trigeneration plant

4 Acoustic Enclosures installed to Ferentino energy plant (FR – Italy). A solution consisting of a 2.7 MW engine, a recovery boiler, and an absorption system.

Grastim chooses Stopson Italiana’s solutions for the soundproofing of the new Ferentino plant, owned by Froneri.
The joint venture between Nestlè and R&R has – in facts – allocated to the company specialized in efficiency for the industry, a considerable amount for the supply of the energy service within the European Gelato Motta pole.

The typology of the plant is “trigeneration”, a particular field of cogeneration systems. In addition to producing electricity, it allows the use of thermal energy recovered from the thermodynamic transformation, also to produce refrigerating energy, that is chilled water for air conditioning or for industrial processes, up to a temperature of -60 degrees.

The plant is equipped with a 2.7 MW motor, recovery boiler and an ammonia absorption plant. Thanks to it, Froneri will save significant annual energy cost, reducing CO2 emissions.

The installation – completed at the end of 2018 – concerns 4 enclosures with different applications:

  • N.1 Acoustic Enclosure for cogenerator
  • N.1 Acoustic Enclosure for air outlet and tank room
  • N.1 Acoustic Enclosure for air exhaust silencer
  • N.1 Insulated Enclosure for auxiliaries

 

With dimensions 13.3 x 3.1 x 3.5 m (Length x Width x Height), the main soundproof cabin is designed to be installed outside on a concrete floor. The structure is made of galvanized carbon steel sheet, containing a rock wool mat, and protected by an expanded galvanized carbon steel sheet.

The sound-absorbing material – in addition to having soundproofing characteristics – provides properties of rot-proofness, incombustibility and unalterability. The structure was designed by a team of structural engineers to withstand different weight levels and any seismic risks too.

The soundproof cabin guarantees a residual average sound pressure level in the free field of 65 dB(A), measured at 10 meters from the cabin and 1.5 meters from the floor.

 

Stopson Italiana has been present for decades in the world market of soundproofing as one of the leading producers of acoustic enclosure and control cabins.

The soundproofing solutions reduce noise pollution due to various sources, including the main turbines, auxiliary engines, internal combustion engines and generating sets, mobile power generators (mounted on trailers) for the production of electricity, cogeneration plants, natural gas compression units, starting and vacuum pumps, blowers, fans, mills, presses, vibrating devices, power transformers and boilers.

 

Stopson Italiana’s enclosures offer:

  • Noise reduction from 15dB (A) to 50dB (A) +
  • Vibration dampers, anti-shock systems with sound emission control settings
  • Combustion air intake unit with optional air filtration
  • Removal of exhaust gases from combustion engines
  • Internal / external applications
  • Natural, induced or forced ventilation system
  • Integrated lighting, fire protection systems, air conditioning
  • Modular solutions
  • Easy access for operation and maintenance with removable panels or sliding hoods
  • Installation service

Enel Green Power soundproofs the Generation Group No. 3 of hydroelectric power plant in Bordogna with Stopson Italiana’s Acoustic Enclosures

Included in the supply are the ante-operam surveys, the design, the construction, the installation and the phonometric measurements of an acoustic booth, for the historic plant in Moio de Calvi, val Brembana.

 

The soundproofing intervention consisting of an acoustic enclosure for the Enel Green Power plant in Bordogna has recently been completed.

The acoustic cabin was designed to be installed inside the beautiful power plant built in 1932 which, exploiting a useful jump of 546.55 meters and a maximum derivable flow of 12 square meters/sec through two forced pipes that feed 3 hydraulic turbines Pelton is in able to provide efficient power of around 47,000 KW.

Acoustic Enclosure, Bordogna Hydroelectric Plant (Italy)

With a size of 11.6 x 11.1 x 3.8 m, the structure has been made accessible and completely removable by means of a bridge crane in its upper part, in order to facilitate the management of the turbine components.

The air outlet from the system has been designed using an electric fan, which, when coupled to a silencer, expels air outside the plant through an opening located on the central window.

The soundproof cabin was designed to guarantee an average residual sound pressure level of 78 dB (A), measured at 1 m from the cabin and 1.7 m from the floor.

Stopson Italiana acoustic enclosures are modeled around every type of noisy equipment, internal or external, on skid and on the ground. They are designed to provide excellent attenuation of sound emissions in any critical environment. The realization takes place in modular acoustic panels and coatings for noise insulation, guaranteeing at the same time the maintenance of the equipment, ventilation, weather protection and fire safety.

 

The typical applications of acoustic enclosures are:

  • Energy production systems, including gas turbine steam turbines, traditional and industrial recovery boilers, diesel generators;
  • Cogeneration plants (CHP);
  • Natural gas compression networks and facilities;
  • Manufacturing and process industry: for example the automotive industry, paper industries, printing houses, etc.

Everything You Need to Know about Noise Pollution

How to limit the noise propagation (not only in Oil and Gas). Risks and countermeasures of a phenomenon as important as universally underrated.

The noise pollution’s matter has become a well-documented public domain anthology by now.

The World Health Organisation has reported that 40% of Europe’s population is exposed to noise levels in excess of 55dB. Moreover, noise pollution is ranked as second to air pollution, in terms of affecting our health and wellbeing, including diabetes, tinnitus and risk of heart disease.

Noise pollution in Oil and Gas

According to recent study achieved by PSE Healthy Energy and West Virginia University, some modern Oil and Gas techniques – such hydraulic fracturing (or “fracking”) – produce noise that may increase adverse effects on human health. 

A fracking well in Colorado, pictured in 2012

Fracking can create noise at levels high enough to harm the health of people living nearby (source phys.org). “Oil and gas operations produce a complex symphony of noise types, including intermittent and continuous sounds and varying intensities,” argued PSE Healthy Energy Executive Director Seth Shonkoff.

A adequate set of policies should be specified, in order to safeguard residents and communities, such particularly vulnerable populations (e.g. schools and hospitals). Noise mitigation techniques like perimeter sound walls, noise barriers and acoustic enclosures could represent the most appropriate solutions to hold back this phenomenon.

Noise impact on marine species

This is not all. A recent study led by International Fund for Animal Welfare, reveals the damaging impact of Oil

Noise pollution can damage marine species

and Gas noise pollution on whales and dolphins. In the report, they put in evidence how new technologies should reduce their impact on marine environment during the exploration phase (source: International Fund for Animal Welfare).

 

Noise and Diseases

Numerous epidemiological studies have linked noise to adverse health outcomes too. They include diabetes, depression, birth complications and cognitive impairment in children.

In facts, apart from damage to hearing, exposure to excessive and constant noise can cause other health problems including:

  • Headache
  • Sleep and heart disease
  • Stress
  • Elevated blood pressure
  • Fatigue
  • Irritability
  • Digestive disorders
  • Increased susceptibility to colds and other minor infections

Noise in Europe: limits and human tolerance

As we know, the loudness of noise is measured in decibels. Sensitivity to noise differs from one individual to the next, but experts believe that damage to hearing occurs when noise levels are higher than 85 decibels, which is about the loudness of heavy traffic.

Every year, 7 million people in Europe die from heart disease, that would put the toll from exposure to noise at around 210,000 deaths. In England heart disease kills 110,000 people annually, so the deaths linked to noise could be around 3,300.

2% of Europeans suffer severely disturbed sleep because of noise pollution. The researchers calculate that chronic exposure to loud traffic noise causes three per cent of all cases of tinnitus, in which sufferers hear constant noise. Length of exposure is important too. In facts, it is not recommendable to listen to noises of 109 decibels for any longer than two minutes in row.

Noise and public health in U.S.

In US the noise phenomena has been studied deeply, causing a direct response by public healthThe Health Impacts Project (HIP) provides since 2013 guidance for policy makers to identify the health consequences of potential projects by making public a national sample of health impact assessment.

Exposure Limits in U.S.

The U.S. EPA recommends an average 24-hr exposure limit of 55 A-weighted decibels (dBA) to protect the public from all adverse effects on health and welfare in residential areas. This limit is a day–night 24-hr average noise level (LDN), with a 10-dBA penalty applied to nighttime levels between 2200 and 0700 hours to account for sleep disruption and no penalty applied to daytime levels.

Stopson Italiana delivers 30 Vent Silencers to Karbala Refinery in Iraq

Flawless completion of the supply to HDGSK JV for the SCOP refinery plant in Karbala province.

Stopson Italiana has recently completed delivery of 30 silencers to be installed at Karbala Oil Refinery in Iraq for HDGSK JV, the joint venture led by Hyundai Engineering & Construction (HEC) with GS Engineering & Construction Corporation, SK Engineering & Construction Company Limited and Hyundai Engineering Company Limited.

The whole supply has been divided into three batches applicable to different plant sections:

  • 10 vent silencers for the chemical equipment section including vacuum distillation, i.e. steam and mix of steam and methanol or H2, with flow rates from 10 to 40 t/h, temperatures from 388 °C to 456 °C, noise levels 85-90 dB(A) @ 1 m.
  • 15 vent silencers for the petroleum processing section, i.e. steam, mix steam air and N2 with flow rates from 0.5 to 33 t/h, temperatures from 194 °C to 375 °C, noise level 85 dB(A) @ 1 m.
  • 5 vent silencers for the utilities section, i.e.HP-LP-MP-Start-Up steam, with flow rates from 6.6 to 73 t/h, temperatures from 220 °C to 400 °C, noise level 90 dB(A) @ 1 m.

All silencers have been engineered according to the highly demanding EPC and end user’s technical specifications and manufactured in Italy in special materials, including stainless steel for internal components.

2015-11-30 10.42.55Stopson’s Vent Silencers can be installed downstream any device acting as a link between a container of pressurized gaseous fluid and the atmosphere. The vent silencer can also provide high or low back pressure relief for the system ensuring proper operation.

Vent silencers can be reactive, absorptive or combined type depending on applications and required attenuation, which can reach as much as 75 dB(A).
SPM Vent Silencers, used for higher flows and back pressure, are based on a combined reactive and absorptive principle for noise reduction: the gases expand to atmospheric pressure through a perforated diffuser, providing a first important step in attenuation; the flow evolves into a sound-absorbing lining section to further contribute to reach required noise residual level.PSP

PSP Vent Silencers, used for lower flows and back-pressures, feature an expansion chamber upstream the final absorptive section with no diffuser at the inlet.

A special sound-proofed weather hood is finally heading flow and noise upward, while delivering an effective rain protection and drainage.

Typical Applications for vent silencers are:

  • Safety Valve (PSV)
  • Relief valve (PRV)
  • Control valve
  • Ejector
  • Start up valve
  • Snort-valve
  • Flash and Blow Down Tanks

Oil market rocked by new Russia-Saudi Arabia deal

Saudi Arabia and Russia agree on oil co-operation that could limit supply.

The news has been spread around in a matter of seconds. Saudi Arabia and Russia together for an ‘historic’ oil market co-operation.
The core of the deal has been focused on the output’s limitation, with the aim to boost the oil prices sharply higher to tackle a global glut. In a joint-statement taken place during the the G-20 summit in China (last Monday), Russia and Saudi Arabia recognized the need to contain excess volatility in the market (source Telegraph). The two oil giants will thereby establish a working group to monitor the market and draft recommendations to keep oil prices steady and ensure solid investments in the industry. Crude oil futures rallied heavily in the build-up to the announcement and pared back slightly afterward. WTI futures for October remained over 3 percent higher on the day, however, at a little under $46 per barrel.
Russian Energy Minister Alexander Novak said that the countries are now discussing the details of a supply freeze deal ahead of an informal meeting of the Organization of Petroleum Exporting Countries (Opec), together with Russia, later this month in Algeria. “We are considering a production freeze as the most efficient tool, concrete parameters are being discussed at the moment,” he argued.
One of the other hot topic concerned the agreement between the two countries to exchange information and experience about new technologies in the oil and gas, and power generation sectors. Considering the several attempts to boost crude prices by freezing OPEC’s output have fallen in the past, the present deal seems to be presented as “historic moment” by the same Novak, particularly because Saudi Arabia has been wedded to keeping output high to hold market share.
In facts, Saudi Arabia is de facto leader of the oil cartel, but Russia is not a member.

 

Stopson Italiana awarded new contract to supply 49 Vent Silencers for Jazan IGCC Project in Saudi Arabia

Major project win from Saipem for the Saudi Aramco – Jazan IGCC Gasification Pack 1 expected to be delivered end of 2016.

Stopson Italiana has been recently awarded by Saipem SpA a major contract for the supply of 15 Oxygen, 15 Process Steam, 15 Start-up Steam and 4 HHP Steam Silencers for the gasification unit at Jazan IGCC (Integrated Gasification Combined Cycle) power plant project. The 2,400 MW Jazan plant will be the world’s largest gasifier-based power plant to be located adjacent to the 400,000-b/d refinery under development at Jazan Economic City, Saudi Arabia, where Stopson Italiana also supplied silencers to JGC Corporation.

sketchThe 49 vent silencers will be engineered according to the highly demanding Saipem and Saudi Aramco’s technical specifications and manufactured in Italy in special materials, including Monel 400 for the Oxygen silencer.

Stopson’s silencers are based on a combined reactive and absorptive principle for noise reduction: the gases expand to atmospheric pressure through a perforated diffuser, providing a first important step in attenuation; the flow evolves into a sound-absorbing lining section to further contribute to reach required noise residual level. A special sound-proofed weather hood is finally heading flow and noise upward, while delivering an effective rain protection and drainage.

Flow rates range from few metric tons per hour to a maximum 270 t/h, targeting a residual sound pressure level of 85 dB(A) at 1 m from equipment.

Stopson’s Vent Silencers are designed to reduce noise level of exhaust piping to the atmosphere for pressurized gaseous fluids, such as air, vapour, natural gas, nitrogen, oxygen, carbon dioxide, etc. They can be installed downstream any device acting as a link between a container of pressurized gaseous fluid and the atmosphere. The vent silencer can also provide high or low back pressure relief for the system ensuring proper operation.

Vent silencers can be reactive, absorptive or combined type depending on applications and required attenuation, which can reach as much as 75 dB(A).

Typical Applications for vent silencers are:

  • Safety Valve (PSV)
  • Relief valve (PRV)
