After its recent participation to Power-Gen Europe, Stopson will fly to Seoul to present its new brand and showcase the technological excellence of its products and services.

For all those attending, Stopson Italiana will make available its technical expertise to support any demanding requirements to develop new sound-proofing solutions in the Power Industry.

POWER-GEN Asia has, over its 24 year history, become the leading force in delivering a platform for the power industry to meet, share information on the challenges facing the power industry and discuss solutions for advancing Asia’s energy future.

Visit us at Power-Gen Asia, booth E53!



Attracting over 8,300 delegates and attendees from more than 85 countries across South East Asia and around the world, it is the industry’s premier conference and exhibition dedicated to the power generation, renewable and alternative energy and transmission and distribution industries. Benefit from four days packed with technical tours, more than 50 conference sessions, panel discussions, a comprehensive exhibition and multiple networking events as we move the event outside of the ASEAN region for the first time in over a decade. With its rising prominence in the global economy, developing Asia’s energy capacity has become a major focus within the marketplace. Asia’s energy needs will expand in tandem with its growing economic influence. Expanding renewable energy sources will not be enough to meet future demand alone. Consequently, Asia needs to invest in making conventional power cleaner and more efficient.
Since 1965 Stopson Italiana has been considered one of the largest provider of noise control solutions such as silencers, enclosures, vent equipment and test facilities for any industrial applications.
Power-Gen Asia 2016, will take place this year in Seoul, September 20-22, and Stopson Italiana will be exhibiting at Booth E53.

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
