I’ll go first to serve as a starting point: the system is stable; the dry gas is not completely dry, the C2 content in the liquefied gas is high, and the non-condensable gases are vented to the flare – if they’re not vented, overpressure occurs； The more the absorption tower absorbs, the greater the amount of dry gas that consists of components other than C3 ； Increased desorption results in an increase rather than a decrease in LPG C2 levels – what’s going on?
In delayed coking production, ensuring the stable operation of the equipment is crucial. Some possible problems include: coking inside the furnace, blockage of the tray plates, and insufficient efficiency of the condenser. Solving these problems usually requires strict control of operating conditions, as well as regular maintenance and cleaning of the equipment. At the same time, to address the issue of excessive C2 content in liquefied gas, considering adjusting the operating parameters or using a more suitable absorbent could be an option. .
