吉化炼油厂250万t/a常减压蒸馏装置为燃料-润滑油型生产装置。1994年其减压系统改造后,换热介质由原来的8种增加至13种,换热器由原来的38台增加至44台,但原油换热终温仅达270～280℃,远低于国内先进水平。1996年,炼油厂委托吉林化工学院对该装置换热网络进行重新优化设计,于1997年8月检修期完成了改造工程,改造投资200万元。 本次技术改造主要对换热网络中冷热物流的匹配换热顺序进行了重新调整,共调整了26台换热
Jilin Chemical refinery 2.5 million t / a atmospheric vacuum distillation unit for the fuel - oil-based production plant. After its decompression system was transformed in 1994, the heat transfer medium increased from 8 to 13 and the number of heat exchangers increased from 38 to 44, but the final temperature of crude oil heat exchange only reached 270-280 ° C, much lower In the domestic advanced level. In 1996, the refinery commissioned Jilin Chemical Engineering Institute to re-optimize the heat exchange network of the installation and completed the renovation project in August 1997 overhaul, with an investment of 2 million yuan. The technical transformation of the main heat exchange network in the hot and cold logistics matching heat transfer sequence has been re-adjusted a total of 26 heat exchange
