120,000 Tons / Year Of Synthetic Ammonia Project To Change The Tower Within The Pieces Of Transformation

Xiangyang Zedong Chemical Group Co.,ammoni acar a year，due to use of high-sulfur coal, increase the processing load shift gas desulfurization, vice desulfuri zationsolution to generatet he amount of salt increases, increase the desulfurization towerpacking layer vice cumulative amount of salt, shift gas desulfurization tower pressureexceeds the design value,gradually rose to80kPa, H2S exceeded desulfurization, dropachieve desulfurization efficiency50mg/m3,desulfurization tower phenomenon alsooccurs with liquid, a serious threat to the safe operation of the compressor;afterincreasing the amount of solution circula-tion,little effect; trans form large gasdesulfurization system pressure,over pressure caused by conversion system,productionsafety threat,increasing the compression of electrical energy consumption;Transform gasdesulfurization become a key factor restricting the produc-tion.In this criticalsituation,according to my company to change the country’s new equipment to expandchemical energy requirements, the use of new technology, new equipment, newmember,Our ammonia Branch120,000tons/year of synthetic ammonia projecttransform sectionΦ3600×45000becomes de-institute the original design for the towerpacking tower，according to the production of semi-water gas demand based onhigh-sulfur coal combustion materials,equipment maintenance cycles market researchand decided to use QYD newt rim plate column instead of a packed tower.
