Diesel adsorption separation process passed the review

　　Sinochem News News Recently, the 1 million tons/year diesel adsorption and separation unit of the transformation and upgrading project of PetroChina Jilin Petrochemical Branch undertaken by China Kunlun Engineering Company has completed the review of the process package
.

　　"This technology separates excess diesel into non-aromatic and aromatic components by simulating a moving bed adsorption separation process.
Non-aromatics are used as high-quality olefin cracking raw materials, which can meet the demand for high-quality raw materials in downstream ethylene units.
means to produce aromatic hydrocarbon raw materials
.
" said Sun Fuwei, deputy general manager of Kunlun Engineering Company's New Materials Division
.

　　In addition to the adsorption and separation of diesel oil, the technology can also be applied to the adsorption and separation of atmospheric gas oil (AGO)
.
Previously, the 2 million tons/year AGO adsorption and separation project of Fuhai Chuang Petrochemical Co.
, Ltd.
undertaken by Kunlun Engineering completed the process package review
.
Up to now, on the basis that the total cumulative technology license scale of this technology has exceeded 1 million tons per year in 2021, the single-series license scale has rapidly exceeded one million tons
.

　　According to Sun Fuwei, this technology, as a "converter" for oil processing paths, connects the industrial chain of "refining-olefins-aromatics-high-end chemicals" with low-energy consumption, flexible and controllable "molecular-level stereo-directional processing" capabilities
.
This technology not only meets the needs of high-quality self-supplied raw materials for crackers, but also meets the further reduction of oil products.
At the same time, it can reduce the amount of low value-added products such as cracked fuel oil, reduce the amount of coke, and reduce hydrogen consumption, effectively reducing consumption and emission reduction
