Study on the optimization of dehydration technology under pressure boost mode in Jingbian gasfield
With the gradual implementation of the boosting production project in Jingbian gasfield,the pressure of gas gathering station has reduced.The deviation between production conditions and design conditions of dehydration process may cause the natural gas water dew point unable reach the standard.Centering about the analysis of the adaptability of dehydra-tion process under boosting production mode,the main reasons that affect the natural gas water dew point of dehydration unit products have been identified.Through reducing the pressure of the flash tank and the frictional resistance of circulating pump operation,adding a gas heat exchanger to reduce the discharge temperature of the compressor et al,low-pres-sure operation of the dehydration sled is achieved,the natural gas water dew point is reached the standard,which has reference significance for guiding the improvement and optimization of surface technology supporting the pressurized production of Jingbian gasfield.
