The desorption tower in absorption and stabilization System of 0.8mt/Y DCC unit in Jingmen General Petrochemical Works was revamped with middle reboiler technology. The purpose of revamp was to decrease the quantity of heat of the bottom reboiler and reuse the heat of stabilization gasoline. 荆门分公司0.8Mt/年DCC-Ⅱ装置吸收-稳定系统解吸塔采用中间再沸器节能技术改造,以回收稳定汽油余热,降低解吸塔底再沸器热负荷。
The double lift pipe in a 800 kt/ a catalytic cracking unit, including reaction – regeneration fractionation, absorption – stablization, waste heat boiler and gasoline mercaptan removal, was remoulded. 中国石油锦西石化公司采用石油大学与华东设计院共同开发的双提升管催化裂化技术,对80万t/a催化裂化装置反应$C再生、分馏、吸收稳定、余热锅炉、汽油脱硫醇等部分进行改造。
The catalysis decomposition method. the selective reduction catalysis method and the absorption reduction catalysis method for reducing NOx emissions of lean combustion gasoline engines are briefly introduced. 简述了降低稀燃汽油机NOx排放的催化分解法、选择还原催化法和吸附还原催化法。
The Research Progress of the Absorption Desulfurization Technology of Fluid Catalytic Cracking ( FCC) Gasoline 硫化催化裂化(FCC)汽油吸附脱硫工艺的研究进展
Gasoline vapour recovery methods mainly include absorption, adsorption, condensation and membrane separation, and adsorption is an effective gasoline vapor recovery technology. 汽油蒸气的回收方法主要包括吸收法、吸附法、冷凝法、膜分离法,其中吸附法是一种有效的油气回收技术。
Due to small absorption selectivity, crude gasoline absorbed some C2, C1 and N2 while absorbing LPG. 由于吸收选择性较小,粗汽油在吸收C2和LPG的同时,也吸收了部分的C1和N2。
