低温降、低压降减压转油线的设计和计算

DESIGN AND CALCULATION OF VACUUM TRNSFER LINE WITH LOW TEMPERATURE DROP AND LOW PRESSURE DROP

介绍了乌鲁木齐石油化工总厂常减压装置减压转油线的改造情况，通过设计、计算和实际标定证明，改造后的减压转油线具有温降低、压降低、汽化率高的特点。因而，改善了油品质量，提高了减压拔出率，取得了较好的经济效益。

The reconstruction of vacuum transfer line of atomosphere and vacuum unit for Wurumuqi petrochemical complex is recomended.By means of design,caculation and actual standardization,the reconstructed vacuum transfer line has the features of how temperature drop,has pressure drop and hign vaporous rate.For this reason,the oil quality is improved,the rate of vacuum distillate oil is increased,and a good economic benefit is obtarised.
