In order to solve the issue that the gas field water treatment capacity of natural gas treatment plant at the right bank of Amu Darya river block B can't meet the production of upstream gas field, ensure rapid construction and investment recovery,PetroChina Amu Darya Gas Exploration and Development company in China takes the lead to organize technical forces from research institutes and construction companies to carry out field research at the gasfield of Amu Darya rive and initially form water treatment technology of “hydrogen sulfide removal by gas stripping + air flotation" and the skid-mounted technology of “hydrogen sulfide removal by oxidation + oil flotation”, which operates smoothly after put into use and effectively solves the issue of water treatment at gasfield. At the same time, combined with the actual production conditions, application is optimized and performance is improved as well to enhance the efficiency of gasfield production at Amu Darya river.
