Design and Running of Reforming Unit with Low Pressure Combination Bed

Design and evaluation of the 11 630 b/d low pressure combination bed reforming unit which was from revamping a 3 489 b/d fixed bed reforming unit in Changling Company,China Petroleum and Chemical Corporation were introduced,especially design characteristics of continuous regeneration of reforming catalyst.Following technologies were adopted in design of the unit, prehydrotreating plus stripping tower for pretreatment,a lower pressure of 2.2 MPa at inlet of the prehydrotreating reactor,fixed bed reforming with catalyst semi regeneration for forepart of the reformer and moving bed reforming with continuous catalyst regeneration for the back, "dry cold" recycle process for catalyst regeneration system.The evaluation results showed that the yield of depentanized oil is 82.62%,the octane number ( RON ) is 100.8 and the energy consumption of the unit is 3 564.9 MJ/t.
