The molecular sieve selectively adsorbs molecules according to their different properties in liquid air separation plant. According to the size of the molecules, the molecules smaller than their pore size are selected for adsorption; for molecules of similar size, according to the polarity of the molecules, the more polar molecules are selected for preferential adsorption; according to the saturation of the molecules, the larger the unsaturation, the easier they are to be adsorbed and the more substances are adsorbed; according to the boiling point of the molecules, the molecules with high boiling point are selected for adsorption first.
Dear Air Separation provides preliminary design of small air separation unit and large air separation plant and engineering documents services for clients. Preliminary design includes: foundation design, process design, general drawing design, technical specifications and design forms, budget estimates, and various data reports.
