吉林省扶余炼油厂3.0万吨/年Ⅳ型催化裂化装置是我国第一个全部加工扶余原油常压渣油全馏份的工业装置.由于常渣催化时生焦率大(约为9.5～10.0%),再生器内过剩热量较多(约占总烧焦放热的20%),故在二密相内敷设了八根三组取热管.其中一组两根、另两组各三根,各组在再生器外均单设有上、下联箱共用一个卧式汽包(见图1).各联箱与汽包单独相 Jilin Province Fuyu refinery 30,000 tons / year Type IV catalytic cracking unit is China’s first complete processing Fuyu crude oil whole fraction of the industrial unit. Due to the residue when the raw coke rate (about 9.5 ~ 10.0 %), More excess heat in the regenerator (about 20% of the total scorch exotherm), so in the dense phase of the laying of eight three heat pipe, one of two, the other two three, Each group is outside the regenerator are provided with a single, upper and lower header share a horizontal drum (see Figure 1). Each header and drum alone
