Experimental Study of Gas-Liquid Separation and Recovery Characteristics of Leaking Oil-Gas Mixtures in Alkylation Process
Alkylation process is the key to supervise the dangerous process,and the dangerous materials after leakage are easy to cause fire,explosion and other secondary accidents. It is important to separate and recover the gas and liquid multiphase mixture to reduce the risk of accident and prevent the escalation of accident. A new type sleeve gas-liquid separator was designed,and the recovery amount and separa-tion efficiency of shallow liquid layer and pure liquid leakage with different physical properties were studied at different fan frequencies and liquid filling heights,and the performance of key components of gas-liquid separation was analyzed and optimized. The results showed that the leakage recovery of shallow liquid layer and pure liquid decreased with the increase of viscosity,and the maximum reduction was 55％ and 20％,and the maximum recovery was 25 kg/min and 98 kg/min,respectively. For volatile liquids,the separation efficiency was close to 100％,and for me-dium and high viscosity liquids,the overall efficiency was more than 80％. The optimized uprotating liquid-gas-liquid separator increased the recovery of high viscosity liquid by about 20％ and reduced the pres-sure drop by about 10％.
