The Sewage Treatment Process Optimization Research Of The Third Natural Gas Treatment Plant In SuLige Area

At present, Sulige gas field has entered into a stable development phase, Gas output sewage quantity continuously increase, because of its contains a lot of organic matter, and dissolve the different degree of hydrogen sulfide, carbon dioxide and acid gas, if it wouldn’t get reasonable treatment and discharge, it Will not only on the treatment facilities, recycle system to produce corrosion or jam, make gas wellbore pipe string and ground facilities can not run normally, affects the gas safety production, But also for formation caused by blocked receiving waters creep sexual assault, the pollution of ecological environment. Therefore, carrying out the Sulige sewage treatment comprehensive research has important realistic significance and broad application prospects to improve gas production capacity, improve the gas field development life, reduce the production cost of operation, protect the ecological environment.Through this thesis research and analyzing the Sue sulige third plant sewage properties, Optimization alcoholic wastewater and low alcoholic wastewater pretreatment process, make wastewater pretreatment process and gas field actual production to adapt; methanol recovery unit operation parameter optimization, and field experiment, Make methanol recovery unit performance meet the field production process and performance design requirements. Ensure that methanol recovery unit is in normal operation and the product is qualified methanol.
