Analysis of operability of low-temperature ethane tanks for propane storage
Based on the planning and the actual situation of production and operation of refining enterprises,the operability of converting low-temperature ethane storage tanks into universal ethane and propane storage tanks was explored and analyzed.The results show that tank cleaning and replacement is required before converting ethane storage tanks into propane storage tanks be-cause the same storage tank cannot be used to store low-temperature ethane and low-temperature propane as well;the conversion of low-temperature ethane tanks to propane storage tanks is theoretically feasible in the case that the capacity,material and load of low-temperature ethane tanks meet the design requirements for propane storage;and for the enterprises that need to import large amounts of ethane and propane to meet the simultaneous operation of light hydrocarbon cracking and propane dehydrogena-tion units,using low-temperature ethane tanks to store propane can achieve the adaptable use of low-temperature liquid hydrocar-bons to balance light hydrocarbon resources.
