Experimental Study on Single-stage Hydration Separation of High Ethane Dry Distillation Gas
In this study,the separation experiment of high ethane distillation gas was carried out by hydrate method.The effects of gas-liquid ratio,temperature and pressure on gas separation were investigated.After the single-stage separation of hydrate,the composition of hydrocarbon gas(methane/ethane/propane)in the hydrate phase increased from 79.12％ to 91.22％,and the composition of methane gas changed little,while that of ethane and propane changed greatly.The maximum recovery rate can be increased to 43.30％,which improves the utilization value of dry distillation gas,reduces the waste of resources,and protects the ecological environment effectively.
