Organic heat carrier online reducing acid value technology and device

The invention discloses a organic heat carrier online reducing acid value technology and device and belongs to the technical field of organic heat carrier regeneration technology and device. The invention adopts the method of neutralization and precipitation by adding complexing agent and solubilizer, the substandard organic heat carrier is recycled online and regenerated online when tasks of clients are urgent and production is not stopped without effecting continuous production. By the adoption of the technology, harmful components can be separated thoroughly, acidic substances are adsorbed and filtered, and the substances which hamper system safe, economic and smooth operation are discharged from the system, and the quality of the oil in the system reaches GB24747 oil standard. 有机热载体在线降低酸值的工艺及装置，属于有机热载体的再生处理工艺和装置技术领域。本发明采用加入络合剂和增溶剂中和沉淀的方法，把在用不达标的有机热载体在线再生回用，在用户任务紧不停车的状态下，进行在线再生，该工艺可达到不影响连续生产的目的。本发明能实现对有害组分的彻底分离，经过吸附过滤，分离出酸性物质后，把妨碍系统安全、经济、平稳运行的物质排出系统外，使系统内油品达到GB24747在用油标准。
