C.O.R.U. Project Moscow

Stopson Italiana delivers Vent Silencers for Refinery and Petrochemical Projects in Russia

EAC certified vent silencers successfully supplied for Oil & Gas projects in Moscow and Kingisepp

Stopson Italiana has recently completed delivery of 10 silencers to be installed at Combined Oil Refinery Unit (CORU), in the Moscow Refinery and 9 vent silencers to be installed at the new Ammonia plant under construction in Kingisepp, Russia, according to the data below:

  • C.O.R.U. Project – no. 10 SPM and PSP vent silencers for the Combined Oil Refinery Unit, with flow rates from 0,4 to 46 t/h. Temperatures from 150 °C to 450 °C, noise levels 80 dB(A) @ 1 m.
  • Kingisepp Project – No. 9 SPM vent silencers for the Ammonia plant, i.e. Steam and CO2 with flow rates from 1 to 130 t/h. Temperatures from 110 °C to 515 °C, noise level 85-110 dB(A) @ 1 m.

9 SPM Vent Silencers Ammonia PlantAll silencers have engineered according to the highly demanding EPC and end user’s technical specifications. They have been manufactured in Italy in special materials, including stainless steel for internal components, and certified in accordance with EAC TR CU 010 standards for Russian market.

Stopson’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.

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 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.

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)
  • Control valve
  • Ejector
  • Start up valve
  • Snort-valve
  • Flash and Blow Down Tanks

Stopson Italiana Vent Silencers soundproofs the Cold Flow Turbine Test Facility, one of the most world-class avionics project

5 Steam Vent Silencers successfully installed in Poland in the world’s most modern laboratory for aeronautical turbine test.

Industrial soundproofing covers various sectors and applications. Thanks to its expertise, Stopson Italiana is able to provide turnkey service in the acoustic insulation applied to Power Generation, Oil & Gas, Marine and Avio sectors.

For this latter, several noteworthy installations have been delivered. Among these a huge supply of vent silencers with their respective jet air turbine test chambers has been developed to for GE Avio.

The installation of “PoloniAero” was inaugurated at the end of 2015, and it still represents a unique example of cooperation between universities and industry. The structure – one of the largest and most avant-garde laboratories in the world – was financed by EU funds. The objective is the turbine test for low pressure (and next-generation) aeronautical engines, as well as technological demonstrators used for the construction of aeronautical engines.

The Cold Flow Turbine Test Facility combines the scientific expertise of Poland with the aerospace industry innovation. The partners of the Polish Aero scientific-industrial company are Avio Aero, Military Aircraft Works No. 4, the Warsaw University of Technology and the Military University of Technology. The ultimate goal of the choral project concerns the development of aerospace industry activities, including aeronautical turbine testing.

Stopson Vent Silencers are designed to reduce the noise level of exhaust pipes in the atmosphere for pressurized gaseous fluids. They can be installed downstream of any device that acts as a connection between a pressurized gaseous fluid reservoir and the atmosphere. The Steam Vent Silencer can also provide a high or low backpressure to ensure the proper operation of the system.

Noise reduction is achieved by two principles: a reactive section, useful for attenuating low frequencies; and a high frequency absorption section possible by inserting a sound-absorbing material.

Ventilation silencers can be reactive, absorbent or combined, according to the applications and required attenuation, which can reach up to 75 dB (A).

Typical applications for vent silencers are:

  • Safety Valve (PSV)
  • Ventilation Valve (PRV)
  • Control valve
  • Ejector
  • Starting valve
  • Snort valve
  • Flash and Blow Down Tanks
