乙炔加氢反应器全周期操作优化
Full-cycle operation optimization of acetylene hydrogenation reactor
摘要
Abstract
Acetylene hydrogenation reactor is an important unit operation in ethylene process, whose operation deeply influences yield and purity of ethylene product. Within an operating cycle, the catalyst activity in reactor gradually declines with time, the operating point will slowly deviates from the initial steady-state design point such that the ethylene yield will drop. To implement the full-cycle operation optimization, the kinetics model of catalyst deactivation considering green oil accumulation is presented through deactivation mechanism research, then a two-dimensional heterogeneous dynamic model of acetylene hydrogenation reactor with modified catalyst deactivation equation is proposed. The full-cycle simulation on gPROMS software verifies the correctness of modified model, and the full-cycle operation optimization is solved by Matlab optimizer on upper layer interacting with gPROMS simulation. The optimization results show that, the full-cycle operation optimization is superior to the fixed value temperature compensation in regard to both the economic benefit and the regeneration cycle of reactor, and the full-cycle operation optimization simultaneously optimizing inlet temperature and hydrogen input is of greater advantage.关键词
