By re-contacting the recycle hydrogen from the low pressure separator of a catalytic reformer with reformate under high pressure, a new equilibrium is reached and a hydrogen stream with higher purity is obtained. 在重整流程中采用一种简便易行的办法提高氢纯度,即将低压分离罐的氢气与重整生成油在较高压力下再次接触,气液重新达到平衡,分离出的氢气纯度要比原来高。
The RBI technique is used to analyze cool high pressure separator, cool low pressure separator and pipeline for hydrogenation plant, the inspection plan was developed based on the risk assessment results. 运用RBI技术在加氢装置冷高压分离器和冷低压分离器及相连管线进行的RBI分析过程,并根据风险分析的结果制定了检验计划。
