【摘要】：為進(jìn)一步挖掘煉油裝置節(jié)能潛力,降低能量消耗,利用熱聯(lián)合原理對(duì)部分裝置用能進(jìn)行分析,發(fā)現(xiàn)常壓原油換熱終溫過(guò)低、焦化蠟油出裝置先冷卻下游再升溫、用蒸汽進(jìn)行工藝伴熱等問(wèn)題,可進(jìn)行常減壓原油與凝結(jié)水換熱、催化與焦化裝置熱進(jìn)料和部分裝置改用熱媒水伴熱3項(xiàng)熱聯(lián)合改造。初步估算改造實(shí)施后可以提高原油換熱終溫10℃、節(jié)約循環(huán)水25t/h、伴熱蒸汽節(jié)約15t/h,累計(jì)降低全廠能耗(標(biāo)油)1kg/t左右,不但降低了能耗和運(yùn)行成本,還取得較好的經(jīng)濟(jì)效益。
[Abstract]:In order to further excavate the energy saving potential and reduce the energy consumption of the oil refining plant, the energy consumption of some units was analyzed by using the heat combination principle. It was found that the final heat transfer temperature of the crude oil under normal pressure was too low, and the coking gas oil outlet unit cooled downstream and then heated up. Heat transfer between atmospheric and vacuum crude oil and condensate water can be carried out by using steam to process heat tracing. It is estimated that the final heat transfer temperature of crude oil can be increased by 10 鈩，
