| Zizhou gas field gas gathering station outside the transmission temperature control in-5 ~ 8 ℃,the state of natural gas in the pipeline is free of condensate water phase saturated wet gas,is moisture vapor transport.But natural gas pipeline transportation due to the temperature and pressure changes that may precipitate condensate water and condensate,which accumulates in the gathering branch lines,affecting production and transport efficiency.Since the gas gathering station outside loses pressure rises faster,higher separation temperature,gas free water not adequately separated in the gas-gathering station,outside the transmission can not be guaranteed delivery of natural gas to gas.To inhibit the formation of hydrates,by way of injection of the methanol,the amount of methanol injected reasonable,it may be cooled to a temperature lower than the natural gas hydrate formation conditions damage,inhibit the formation of hydrates;At the same time,before and after comparison of two separator gas component analysis,optimal operation temperature is increased two separator liquid separation effect.Through research,the results from the sub-continent gas gathering station process optimization program,the future production of some guidance. |
