Dear Air Separation process simulation, 3D design, stress analysis, safety analysis and other software are among the best in the world, providing users with quality and advanced design services.

 

Compared to piston expanders, turbine expanders have many advantages: the efficiency of turbine expanders is higher than that of piston expanders; when turbine expanders work, gas can pass through continuously and at high speed, and the smaller size can expand a large amount of gas; there are no friction parts in the circulation part of turbine expanders, so there is no need for lubrication, which is conducive to reliable operation of the equipment as well as improving product quality.

 

The technical team of Dear Air Separation Equipment consists of experienced experts and specialised engineering designers to provide customers with engineering design solutions in accordance with international standards, national standards and industry standards, including preliminary design and construction drawing design.

The non-power consuming option for liquid air separation plants can be used for full liquid air separation plants,where the produced liquid is sold off. This approach is currently available for most LNG receiving stations. For air separation units with a large cold capacity, the liquid air can be pressurised to 6baA in a vacuum storage tank, and then heat exchanged through a heat exchanger, instead of the air compressor, directly into the cold box for distillation. At the same time in the cold b...

1. Before connecting the pipe orifice of each container, clean white cloth shall be used to tie the orifice to prevent grease and dirt from entering. 2. When welding in the cold box and in the condensing evaporator, it is strictly forbidden for flame or arc to touch the surface of vessels and pipes. 3. The containers, valves, pipes and corresponding supports in the cold box, the surface of the cold box and the foundation surface shall not be stained with grease after installation, otherwise, degreasing treatment shall be carried out.
