摘　　要：为充分发挥南阳原油微晶蜡含量高的资源优势,最大限度生产高附加值微晶蜡产品,南阳石蜡精细化工厂将以生产催化裂化原料为主要目的产品的0．15 Mt/a超临界丁烷脱沥青装置改造为0．18 Mt/a丙烷脱沥青装置,改造采用脱沥青油二段抽提-沉降工艺,核心设备抽提塔应用清华大学开发的溶剂脱沥青高效萃取塔,几年来,装置运行安全平稳,产品轻、重脱沥青油的收率高且质量好,剂耗、装置能耗等技术经济指标均较理想。To maximize the production of high added-value microcrystal wax, the existing 150,000 TPY super-critical butane deasphalting unit whose major product was FCC feedstock has been revamped into a 180,000 TPY propane deasphalting unit using 2-stage extraction-settlement process. The critical equipment of the unit is the high-efficiency solvent deasphalting extractor developed by Qinghua University. The operation of the unit shows that the unit is reliable in operation, high in light and heavy deasphalted oil yield and quality, low in solvent requirement and satisfactory in energy consumption.
