Reducing energy consumption of the complex cleaning unit of the AK1.5 air separation plant

The article considers the possibility of using a complex drying and cleaning unit with separate drying with active aluminum oxide and cleaning with synthetic zeolite of the NaX type in the air separation unit AK1.5, and also considers several circuit solutions for the layout of the complex cleaning unit. As a result of the calculations, the optimal scheme is selected. Such a technical solution will reduce energy consumption for the regeneration of adsorbents, and due to the optimal geometry of the adsorbers and minimal cyclicity of the processes (adsorption-regeneration-cooling) reduce the hydraulic resistance of compressed air.
