A full-package solution aimed at obtaining total sound insulation towards different target parts in an Oil Refinery in Bahrain, which has recently undergone an ambitious modernization program.
Stopson Italiana has successfully concluded the delivery of 172 Vent Silencers to be installed among 4 different structural parts of the Oil Refinery in question. The project assists the expansion program that has been taking place since 2018, and it is expected to reach completion prior to the end of 2022.
The Refinery is situated on the island of Sitra, southwest of the capital city Manaba, and produces about 260,000 barrels per day (bpd) of crude oil and 40,000 bpd of low sulfur diesel.
The project has been carried out according to the following distribution:
- n. 2 HP Export Steam Silencers;
- n. 60 PSIG Steam Vent Silencers;
- n. 110 PSIG Steam Vent Silencers via a second delivery.
And will cover the following areas:
- Safety Systems;
- Blow Out and Clean up;
- Ventilation Systems.
Most of the Silencers have been provided with a removable internal absorptive pack for easy maintenance and clean-up and a removable rain hood. They are all designed to reach a noise target of 82 dB(A) @ 1 m from the silencer.
What is a Vent Silencer
A Vent Silencer is a soundproofing device aimed at eradicating the adverse noises produced by gas or steam flow while piping into the atmosphere. The noise in question can be generated as a result of the high-velocity flow through the valve and/or a turbulence created around any impedance in the line that may cause restriction or simply change the flow’s direction.
Each Vent Silencer is able to provide an overall attenuation of the noise level to the required sound pressure level criteria at a certain distance from the silencer.
At the same time, noise reduction can be attained both using a reactive section to attenuate the low frequencies and absorption mean of the high frequency, normally using a sound-absorbing material.
Stopson Italiana engineers its Vent Silencers in Italy, using special materials not only in accordance with all quality standards but also in line with the client’s specific needs thanks to a careful customer management process.
