Research on Pipeline Transportation of Gas Phase CO2 with Impurities
As a key CO2 emission reduction measure,research on carbon capture and storage technology(CCS)is of great significance.At present,one of the major challenges affecting the widespread implementation of CCS in China is pipeline transportation.In this article,taking the untreated CO2 from an oil field in southwestern China as the research object,its pipeline transportation method was studied.Based on the phase characteristics,environmental conditions,and gas transportation volume of the gas source,HYSYS was used to simulate the gas phase transportation pipeline.The impact of pipeline inlet temperature,inlet pressure,environmental temperature,and elevation difference was further analyzed,and suggestions were made for certain operating conditions.The results showed that increasing the inlet pressure in winter had lower transportation costs,while inlet temperature and elevation had little impact on costs.
