Processes for arsenic removal from hydrocarbon cracking feedstock and deactivation of the catalyst;

Evaluation and Industrial Application of Cracking Feedstock in Tianjin Ethylene Plant;

Basis on petroleum hydrocarbon pyrolysis reaction mechanism and analysis on process of ethylene complex, finding out uppermost influence factor of production cost and specific energy consumption of ethylene complex is cracking feedstock.

This paper introduced the source and the kind of the ethylene cracking stock and the effect of the stock nature on the ethylene production,analyzed the ethylene cracking stock source’s actuality by now of our company,compared the clan component of self-produced naphtha by our plant with the clan component of purchased naphtha and raffinate,evaluated the compatibility of the stock,review.

This paper analyses the present situation and future development trends for cracking stock constitution of ethylene,analyses the constitution characteristics and existing problems for domestic (especially for SINOPEC) cracking stock of ethylene,and proposes the corresponding suggestions for the future optimization of cracking stock of ethylene in SINOPE

Hydrocarbon types of feedstock were determined by using PIONA special analyzer, the properties of cracking feedstock were analyzed and evaluated, then the cracking feedstock and cracking process for ethylene were optimized.
