Abstract: There is no gas phase reflux in the loading process of liquid propylene in China Petroleum & Chemical Corporation Jinan Branch. The pressure of propylene tank gradually increases in the filling process of liquid propylene, and it is easy to reach the upper limit of tank pressure and stop filling in summer. According to the influencing factors of liquid propylene loading in refinery, the influences of temperature, liquid level and pressure in propylene spherical tank, propylene loading flow rate and propylene tank pressure on propylene loading process are discussed and optimization measures are put forward finally. It is possible to ensure smooth loading of liquid propylene in summer by optimizing and adjusting propylene fuel collection, dynamically adjusting loading pump operation, and reducing the pressure of the propylene tanker by cooling and spraying.
