原(yuan)油(you)減壓蒸餾反應釜與反應裝置(zhi)生產工藝,原(yuan)油(you)一般是(shi)帶有鹽(yan)(yan)份和水(shui)(shui),能導(dao)致(zhi)設備的腐(fu)蝕,因(yin)此原(yuan)油(you)在進入(ru)常(chang)減壓之前首先進行脫鹽(yan)(yan)脫水(shui)(shui)預處理,通常(chang)是(shi)加入(ru)破乳劑和水(shui)(shui)。

原油(you)(you)經過流量計(ji)、換熱部(bu)(bu)(bu)(bu)分、沏餾塔(ta)形(xing)成(cheng)兩部(bu)(bu)(bu)(bu)分,一(yi)部(bu)(bu)(bu)(bu)分形(xing)成(cheng)塔(ta)頂油(you)(you),經過冷(leng)卻器、流量計(ji),進入罐區,這一(yi)部(bu)(bu)(bu)(bu)分是(shi)化工(gong)輕油(you)(you)(即所謂的石腦油(you)(you));一(yi)部(bu)(bu)(bu)(bu)分形(xing)成(cheng)塔(ta)底油(you)(you),再經過換熱部(bu)(bu)(bu)(bu)分,進入常壓(ya)爐、常壓(ya)塔(ta),形(xing)成(cheng)三部(bu)(bu)(bu)(bu)分,一(yi)部(bu)(bu)(bu)(bu)分柴油(you)(you),一(yi)部(bu)(bu)(bu)(bu)分蠟油(you)(you),一(yi)部(bu)(bu)(bu)(bu)分塔(ta)底油(you)(you);剩余的塔(ta)底油(you)(you)在經過減壓(ya)爐,減壓(ya)塔(ta),進一(yi)步加(jia)工(gong),生(sheng)成(cheng)減一(yi)線、蠟油(you)(you)、渣油(you)(you)和(he)瀝青。

各自的收率:石腦油(you)(輕汽(qi)油(you)或化工輕油(you))占(zhan)(zhan)1%左右(you),柴油(you)占(zhan)(zhan)20%左右(you),蠟油(you)占(zhan)(zhan)30%左右(you),渣油(you)和瀝青約(yue)(yue)占(zhan)(zhan)42%左右(you),減一(yi)線(xian)約(yue)(yue)占(zhan)(zhan)5%左右(you)。
