Degassing

Degassing Chemicals

Is there an upcoming inspection of your plant? Have your efforts to clean and degas your petro-chemical processing equipment causing you worries? Hydrocarbons and hydrogen sulphide gas and other foul material deposits can be a problem in maintaining refineries, distillation and storage equipment. Traditional mechanical cleaning methods like high-pressure water jetting and cold or hot water washing methods requires several weeks of downtime and generates large volumes of waste water high in TOC which are not environment-friendly. With these situations, more powerful chemical cleaning methods were developed to cut downtime periods and meet or exceed regulatory safety and environmental requirements.

Degassing

Chemical Degassing Process

Prior to degassing process, it is always recommended to conduct decontamination tominimize source of contamination. Tanks can be serviced by spraying proprietary chemistry through manway to collapse vapor space. For process plants, chemical agents that bind solvents and hydrocarbons are directly injected to the steam line. This is known as the vapor phase cleaning process or degassing. Once applied, vapor pressure and flammability drops with LEL levels of benzene, EDC, toluene, xylene and gasoline approaching zero in 1-2 hours. Agents coat equipment surfaces and absorbs hydrocarbon vapors making the tank or enclosed area safe for operation. The vapor phase cleaning process cut up to 80% downtime compared to conventional cleaning process and minimizes waste water by 50%.

Vacuum Degassing

Chemical Degassing Applications

Chemical degassing is widely utilized by process plants to clean vacuum towers, cokers, olefin plants, FCCU fractionators, and HF alkylation units. It is also used to keep process vessels, reactors, interconnecting piping and exchangers sanitary. Above and underground storage tanks with high VOC value chemicals undergoes degassing as well.

In refineries and other petrochemical plants, boilers, tanks, heat exchangers, fin-fan coolers, hydraulic lines, reactors, condenser piping systems, refinery towers and cooling systems are cleaned chemically.
