Causes of too fast increase of the pressure drop and location in the fixed bed reactor of hydrocracker were discussed. 讨论了加氢装置固定床反应器压力降升高过快的原因及产生的位置。
The ISBL of this HP Hydrocracker Unit will start at the unit Filter Feed Vessel and conclude at product rundowns from the Fractionation and the Naphtha Minus Section. 该高压加氢裂化装置的界区从装置过滤器进料罐开始，直到从分馏与脱石脑油段来的产品出料罐为止。
Abstract: Causes of too fast increase of the pressure drop and location in the fixed bed reactor of hydrocracker were discussed. 文摘:讨论了加氢装置固定床反应器压力降升高过快的原因及产生的位置。
The results prove that hydrogen is a major factor to cause the disbonding of stainless steel weld overlay in hydrocracker. 结果表明，氢是引起加氢反应器不锈钢堆焊层剥离的主要因素。
The operation and security status of the reaction furnace of hydrocracker,and its calculation m ethod of the life were introduced. 介绍了加氢裂化反应加热炉炉管运行状况和安全性,并采用拉逊-米勒指数法计算了炉管剩余寿命。
The practical application for a hydrocracker fractionator illustrates that the proposed method is useful to monitor the quality specifications in chemical processes. 该建模方法在加氢裂化分馏塔装置的轻石脑油终馏点在线预测系统中取得了良好的效果。
