【摘要】：對二甲苯(PX)是一種重要的有機(jī)化工原料,工業(yè)上主要采用逆流模擬移動床吸附分離技術(shù)(AST)生產(chǎn)高純度對二甲苯。格柵作為吸附塔的內(nèi)構(gòu)件,是模擬移動床吸附分離技術(shù)的核心之一。根據(jù)格柵的功能,開發(fā)了ACG基準(zhǔn)格柵,運(yùn)用冷模實(shí)驗(yàn)和計(jì)算流體力學(xué)相結(jié)合的方法,對ACG基準(zhǔn)格柵進(jìn)行優(yōu)化,開發(fā)出性能優(yōu)良的ACG-Ⅰ格柵。針對3×10~4 t/a PX工業(yè)裝置,將ACG-Ⅰ格柵進(jìn)行放大試驗(yàn)。運(yùn)行情況表明,開發(fā)的ACG-Ⅰ格柵性能優(yōu)良,工業(yè)數(shù)據(jù)與CFD模擬數(shù)據(jù)比較吻合。
[Abstract]:P-xylene (PX) is an important organic chemical raw material. In industry, high purity p-xylene is produced by countercurrent simulated moving bed adsorption separation technology (AST). As the inner component of adsorption tower, grid is one of the core of simulated moving bed adsorption separation technology. According to the function of the grid, the ACG reference grid is developed. The ACG reference grid is optimized by combining the cold model experiment with computational fluid dynamics, and the ACG- 鈪，
