Who knows the production process for synthetic ammonia in Urumqi’s petrochemical industry?

I would like to know what the production process is for synthetic ammonia in Urumqi Petrochemicals – is it Kellogg? Does anyone here know? This post was last edited by zhanghua on 2008-1-16 17:08]
The second transformation is a Brownian process； One transformation is the project to convert oil to gas
Fertilizer production process: Originally, Texaco gasification used residue oil as raw material; currently, two gasifiers use residue oil as feedstock, while one gasifier uses natural gas. Under normal conditions, two of these gasifiers are in operation； Subsequently, there was carbon black washing and recovery, three stages of sulfur resistance modification, low-temperature methanol washing, and liquid nitrogen washing. The synthesis process originally used the Topsoe S100 series, but it was later modified ； Currently, upgrades are being carried out to convert the feed oil to gas and to increase capacity by 150%; the feed material has been changed to natural gas, with three gasification units in operation. Carbon black recovery has been discontinued. A parallel series is in place, comprising two stages of shift reaction, MDEA decarburization, and methanation, with these processes combining into two synthesis streams. A new synthesis tower has been connected in series behind the old one, and an ammonia recovery system has been added. Two-stage fertilizer production: Brown process: primary conversion + secondary conversion + high/low temperature shift + MDEA decarburization + methanation + deep cryogenic purification + three-tower series combination process + flare gas recovery
