Gas Phase Filtration in Petrochemical Plant and Refinery
Are your Control and Switchgear rooms healthy ???
Bry Air newsletter gas_1
The process parameters in a petrochemical facility are extremely critical, because even a small malfunction can cause tremendous loss in revenues. Petrochemical plants generate fair amount of hydrogen sulphide, sulphur dioxide, and nitrogen oxide, etc Corrosive and Toxic gases like chlorine and ammonia, present in critical areas can corrode critical electronic equipment housed in control rooms / switchgear rooms.
Petrochemical industry can be segregated would require air purification by reinto two parts :
Bry Air newsletter arrow_skip Vertically - Petroleum refiners using pressurization. This is due to the their hydrocarbons to produce absorption of contaminants on clothes primary and intermediate and body surface of plant personnel petrochemical materials.
Bry Air newsletter arrow_skip Horizontally - Firms that manufacture a family of related petrochemicals of similar types or for similar markets.
This industry was one of the first to go for computerization of its process controlled applications, and one of the first to see the need for corrosion control of those electronic process controls. The processes involved in the petrochemical production area generate sufficient quantities of hydrogen sulphide, sulphur dioxide and nitrogen oxide, other than many high molecular weight hydrocarbons. Chlorine and ammonia too are present in small concentrations.
Areas needing Gas Phase Filtration :
Catalytic cracking
Coke plant
Oil by-products
Tank farm
Oil loading/handling areas
Power generation plant
  Gas Purification System
Controlling Gas Phase Contamination in Control / MCC rooms :
In case of rooms with very low movement of personnel coming in and out, only pressurization with chemically cleaned air is sufficient. Provide from 3 to 6 air changes per hour, to attain approximately 2.5 to 5 mm WC positive pressure inside the room
Rooms with high pedestrian traffic, such as Operator Control rooms would require air purification by recirculation mode in addition to airpressurization. This is due to the absorption of contaminants on clothes and body surface of plant personnel. while attending to duties at the different process locations, which are generally highly contaminated. Such absorbed gases would immediately de-sorb upon entry to a relatively cleaner area.

Indian Oil Corporation Ltd., Panipat, referred as one of India’s most modern refineries joined hands with Bry-Air and our Airgineers helped them in removing Gas Phase Contamination from the control room. The toxic gases present in the refinery were depreciating the life of electronic equipments present in control room through the process of electronic corrosion, the problem was duly taken care by the Bry-Air Airgineers. Bry-Air Ecoscrub Air & Gas Purification System was installed in the refinery and the problem was eliminated with full effect, creating a healthy environment for the employees and stabilizing further damages to the electronic equipments.
