Major project win from Saipem for the Saudi Aramco \u2013 Jazan IGCC Gasification Pack 1 expected to be delivered end of 2016<\/strong>.<\/p>\n

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\u2019s 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.<\/p>\n

\"sketch\"<\/a>The 49 vent silencers will be engineered according to the highly demanding Saipem and Saudi Aramco\u2019s technical specifications and manufactured in Italy in special materials, including Monel 400 for the Oxygen silencer.<\/p>\n

Stopson\u2019s 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.<\/p>\n

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.<\/p>\n

Stopson\u2019s 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.<\/p>\n

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

Typical Applications for vent silencers are:<\/p>\n
