重油催化裂化反应-再生系统的热平衡控制

Heat balance control of the heavy oil catalytic cracking unit's reaction and regeneration system

催化裂化的三大平衡为物料平衡、热量平衡和压力平衡，三者相互影响，其中热量平衡是催化裂化装置操作控制的难点。本文通过对重油催化裂化装置的反应-再生系统进行热平衡计算，研究了某催化裂化装置因为再生放热过多，反应-再生系统的热不平衡而引起的问题，提出了对该装置有效的解决方案。

Catalytic cracking unit's three balances are material balance, heat balance and pressure balance.These three balances influence each other. The heat balance is a key problem for catalytic cracking unit operationcontrol. This article reserch the reaction/regeneration system of heavy oil catalytic cracking unit for heat balancecalculation, a catalytic cracking unit are studied for regenerative heat overmuch, reaction/regeneration system ofthermal imbalance caused by the problem, the equipment effective solutions were proposed in the paper.
