The fluid flow and oil-water separation were simulated using a Reynolds stress transport equationmodel of turbulence in water flow and a stochastic model of oil droplet motion. Simulation results gi...
The transition from froth to spray regime on sieve trays was experimentally studied in an air/water simulator with 300mm diameter. It has been found that the regime transition occurs as the clear li...
超重力法吸收醋酸尾气中试研究
超重力法 旋转填料床 吸收 醋酸尾气
2014/3/12
为解决在用醋酐法生产HMX的过程中挥发出来的大量醋酸溶剂，采用中试用的超重力旋转填料床对醋酸尾气进行吸收。采用生消水作为循环吸收剂，考察了超重力因子、液体流量和循环时间对液相醋酸质量分数的影响。结果表明，在超重力因子111、液体循环量0.3m3、液体流量1.0m3/h、循环时间12h后，液相醋酸的质量分数达到60%以上，每年回收的醋酸直接经济效益可达135万元。
