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.

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:

Stopson Italiana delivers Engine Exhaust Special Silencer to CHP Plant in Portugal

Successful installation of an engine exhaust silencer for Capwatt Maia Heat Power S.A. Cogeneration plant.

special-silencer-dwg

 

Stopson Italiana has recently supplied a large size exhaust silencer, SM Special Model, for Wartsila engine installed in a Cogeneration Power Plant, located nearby Maia, in Portugal.
Stopson’s engine exhaust silencer has reactive and absorptive modules in a single body. This acoustic device muffles noise caused by exhausting from cogeneration engine, i.e. as exhaust gases pass through the silencer, noise is diffused and progressively attenuated.

pictureThe gas enters the first stage silencing chamber, where the noise is dissipated. Then the process is repeated into the second chamber, which reacts through a special Venturi with the first one. Main functional data: flow rate 45360 kg/h, design temperature of 374°C, pressure drop of 150 mm H₂O, 65 dB(A) residual SPL at 90° and at 1 m from the chimney outlet.

Each silencer reduces noise differently: the larger the size, the higher the reduction. This engine exhaust silencer has required an accurate fuid-dynamic study in order to comply with problems of transportation and assembly, since the exhaust silencer total weight was of 10000 Kg, while ensuring high acoustic performance, in particular at low frequencies, along with with very low pressure drop.

Stopson’s industrial silencers provide the best performance for all engine applications, either standard or customized models, they can reduce sound emission levels without affecting engine performance.
After installation, acoustics performances are usually tested in order to prove compliance of actual noise emissions with required levels and to ensure plant sustainability within the existing environment.
