catalytic cracker units meaning in Chinese
催化裂化器装置
Examples
- Critical units to be upgraded include fluid catalytic cracker units , cokers , ultracrackers and alkylation units
关键单元的升级包括液态催化裂化装置设备、炼焦器、超加氢裂化装置以及烷化设备。 - Abstract : large time delay exists in complicated practical processes . for example , in fccu ( fluidized catalytic cracker unit ) reactor - regenerator , the feed is preheated through heat exchanging from fractional column slurry , thus results in large time delay . a predictive control system is designed for such processes , where the kernal algorithm is dynamic matrix control . application results show that the control behavior is improved than original pid control
文摘:实际的复杂工业过程，往往具有大的时滞，例如：炼油厂催化裂化装置的反应再生系统，其原料油预热通过油浆换热实现，因此时滞特别大.本文针对这一类大的时滞过程，设计了以动态矩阵控制为核心算法的预测控制系统，运行实践表明：这一控制方案比原pid控制在控制质量上有较大提高
