Proposal on ＂Use of LPG as Steam Cracking Feedstock＂ Raised by the Research Institute of Yangzi Petrochemical Company

The Research Institute of Yangzi Petrochemical Company （YPC） has completed the study on the project ＂Use of LPG as Steam Cracking Feedstock＂ and raised a rationalization proposal. The forecast has shown that the economic benefits for production of ethylene brought about by the hydrocracker LPG are enormous. Compared to the naphtha feedstock currently used by YPC, the economic benefit for manufacturing one ton of ethylene from LPG can be higher by 800 RMB. If the annual consumption of LPG amounts to 220 thousand tons,

Nitrogen Fertilizer Production by Two-step Synthesis in Two Towers with Concurrent Production of DME

Henan Provincial Chemical Fertilizer Company by utilizing the two-step methanol synthesis method in two towers has constructed at Longgang Chemical Co., Ltd. in Qiuxian county, Hebei province a 10 kt/a DME unit, which has delivered the purified DME product. The two-step methanol synthesis method in two towers can fully utilize the heat provided by the utility system and methanol synthesis and the heat delivered during DME synthesis to achieve dehydration of DME, and to carry out rectification by making use of the DME reaction heat,
