2.Nationalizing of GV quipment for 300 thousands ton synthetic ammonia for Guang chou petroleum factory.
3.The comparison result shows that the energy consumption of the reboiler and the condenser used in the DMF method is 33.7% and 22.7% lower than that of the ACN method. The selection of the DMF method for separating butane and butene by extractive distillation is recommended.
4.In consideration of the matching problems in natural gas purification plants, the measures for selecting key equipment in the design of natural gas purification process are proposed based on it purifying requirements and field experimental study. These measures include the selection of virgin gas separators, an actifier column and reboiler , modification of heat exchanger and technical reconstruction of recovery unit, by which safety guarantee is provided for improving production efficiency of natural gas purification.
5.Experimental results showed that the mixed solvents at the bottom and the product at the top of the column can be removed simultaneously for a long period of time in the middle-vessel batch distillation, and thus it requires a much smaller reboiler compared with a regular column.
6.Lead and cadmium in tap water were preconcentrated by Quartz sub-boiling distiller and determined by FAAS in this method.
7.Analysis on the remoulding of overhead cooler for EDC low-boiler column and its running situation
8.This paper introduces several separation technologies for alcohol-water system, which include not only traditional azeotropic distillation and extraction distillation, but also new membrane separation techniques, such as membrane distillation, pervaporation and membrane contactor.
