Heat exchange between the high-temperature ethylene gas produced by bogging and the low-temperature liquid
Thread Content
At present, in low-temperature ethylene storage tanks, the temperature of the ethylene gas coming from the bog compressors is around 120°C. To save energy, it is possible to exchange heat directly with the ethylene liquid flowing downstream; how can stable and adjustable ethylene gas be obtained for use in heat exchange, thereby meeting the needs of downstream production?
It’s simple: heat balance, process design – balancing energy utilization and process stability through calculations and design
One problem is that the amount of ethylene produced by the Bog compressor is not fixed or controllable; it is determined by the pressure in the cryogenic storage tank.
It is necessary to consider whether the BOG gas flow rate is stable, as well as the location and cost implications of using liquid ethylene heat exchangers. One should not focus solely on process optimization, but rather take various factors into account comprehensively.
