Study on Safety in Treatment, Transportation and Injection of Carbon Dioxide in Jilin Oilfield China University of Petroleum (East China) 2010, 09 Contents Introduction Information of CO2 displacement in Jilin Oilfield Dehydration and Purification Safety Analysis Compression and Liquefaction Safety Analysis Transportation Safety Analysis Injection Safety Analysis Conclusions Introduction CO2 is a greenhouse gas. Carbon capture and storage (CCS) is an effective mean to mitigate CO2. Weyburn project: Canada, first commercial example, started in 2000, inject 5000ton CO2/d, enhanced oil recovery by 16%. Sleipner project: Norway, started in 1996, inject 2800ton/d Introduction Introduction CO2 capture, treatment, transportation and injection technologies attract interest. CO2 displacement in Jilin oilfield (China) started many years ago. Matching technologies have been formed Using natural associated CO2 for EOR is performing Introduction This paper has focused on Analyze safety problems and causes in treatment, transportation and injection of CO2 in Jilin oilfield Put forward well-targeted, technically feasible and economically reasonable safety countermeasure suggestions Information of CO2 Displacement Dehydration and Purification Safety Analysis Molecular sieve dehydration technology is used to dehydrate CO2 in Jilin oilfield Corrosion Results leakage explosion and other accidents Measures adding corrosion inhibitors coating on the adsorption tower Dehydration and Purification Safety Analysis Hydrate Results Limiting flow rate Reducing processing gas volume Blocking pipelines Measures adding hydrate inhibitors increasing gas temperature Compression and Liquefaction Safety Analysis Low temperature and low pressure liquefaction technology is used in the CO2 liquefaction Jilin oilfield adopts the liquid ammonia refrigerating machine system Compression and Liquefaction Safety Analysis Leakage of liquid ammonia Results poisoning burning or explosion Measures
