摘要 介绍了原油管道加热输送工艺存在的缺陷、原油改性处理输送工艺的发展史及我国应用化学改性处理工艺的概况。原油改性处理工艺的基本原理是控制条件或添加某种化学的来影响蜡的形态,消弱蜡结合趋势和结构强度,从而推迟原油胶疑的发生。其方法可分为的物理(热处理)和物理化学(添加化学刘)两大类。指出唯有石蜡基或混合基原油一含蜡多者,才有可能用化学剂降凝。有效的降凝剂基本都具有长烃链和极性基的聚合物。其单体中的碳原子数要和原油中的蜡主体部分碳数相适应,才能达到最好的效果。加剂温度、处理温度、降温速率和方式、处理最终温度等是取得最佳效果的工艺条件。对于改性效果的评定,除遵照中国石油天然气行业标准外。还必须做更全面的考察。比较详细地介绍了改性处理工艺实施中的特殊问题。 Introduced in this paper are the shortcomings in heated oil transportation.tne development 01 moameu oil transportation,and the applications of chemical modifying technology in China. The basic principle of modified crude oil transportation is to minimize wax deposition, change the wax's structural strength, and delay the presence of oil gelatification, either by means of controlling working conditions or adding a certain kind of chemical product. The methods used can be grouped into two categories; physical (heating )and physichemicaKaddithive treating). Chemical pour point depression is applicabac only to paraffinic-base or hybrid-base oil. that is. the waxy oil. Almost all effective depressants contain long hydrocarbon chain and polar polymer. Its effectiveness comes from the comform of the number of carbon atoms to the carbon number in wax. Optimum depressing performance, depends on such technological conditions as additive charging temperature, treating temperature, rate and mode of temperature degrading, ultimate treated temperature, etc. Modification performance shall be evaluated according to the enterprise standard of CN-PC, and shall be supported by all-round investigation. Some specific questions in application of modified oil transportation are discussed in detail. It is anticipated that modified oil transportation has a promising future.
