RAX-3000型对二甲苯吸附剂的工业应用

介绍了RAX-3000型吸附剂的物化性能及在某企业的工业应用情况。该企业600 kt/a芳烃联合装置平稳运行5年以上，并在设计负荷的110%原料流量下进行标定，对二甲苯平均纯度为99.8%，平均收率为98.3%，超过了技术合同保证值。生产过程中，水平衡（装置排出的水量与注水量之比）控制在0.8~1.0之间，有利于提高吸附选择性。与参比剂的数据比对表明，RAX-3000型吸附剂在原料适应性、极端工况、吸附容量和压降等方面性能更好。

COMMERCIAL APPLICATION OF RAX-3000 ADSORBENT FOR PX SEPARATION

The Physical and chemical properties and commercial application are mentioned. The 600kt/a PX plant of an enterprise started in operation successfully at the end of 2013 and has been running smoothly since its start-up. The calibration results showed the the average purity and yield of p-xylene were 99.8% and 98.3% ,respectively, which exceeded the guaranteed value of the technical contract.In the production process, the water balance is controlled between 0.8 and 1.0, which is beneficial to improve the adsorption selectivity. Compared with the data of reference agent, RAX-3000 adsorbent has better properties in raw material adaptability, extreme working conditionsand adsorption capacity.
