The design of air separation unit includes the manufacturing design of equipment suppliers and the factory design of users. All kinds of safety standards shall be strictly implemented, including equipment manufacturing, building design, fire prevention, shockproof, ventilation, power distribution, lighting, lightning protection, anti-static, pressure vessel, pressure pipeline, gas cylinder, special equipment safety, low-temperature liquid storage and transportation, various materials, oxygen station design Hydrogen station design and a series of safety standards. Users can also put forward safety technical requirements for equipment manufacturing suppliers according to their own conditions.
The oxygen flow rate in the oxygen pipeline of an air separation unit is an important parameter related to safety. It should be determined according to the material of the oxygen pipeline, the oxygen pressure and whether it is "impact occasion" (the position where the oxygen flow direction changes suddenly or produces vortex, thus causing the impact of the entrained particles in the oxygen on the oxygen pipe wall, such position is called "impact occasion"). The selection of oxygen pipeline material is also a key safety issue, which is directly related to whether the oxygen pressure and location are easy to generate excitation energy, and cannot reduce the standard requirements. Oxygen pipe fittings, elbows, reducers, tees, flanges, threaded packing options are strictly specified. The oxygen filter has strict regulations on the shell, filter material and filter aperture. Special oxygen valve should be used for oxygen valve, which can not be replaced at will. The material, type and operation mode of oxygen valve are related to oxygen pressure, caliber and operation frequency. All kinds of safety regulations, specifications, procedures and standards, especially mandatory standards and clauses, must be strictly implemented.
It is very important to select the design and manufacturing units with rich design experience and various design qualifications. Kaifeng DEAR Air Separation Co., Ltd. has achieved fine, perfect, strict and safe design in terms of material selection for equipment manufacturing according to actual requirements and specific conditions, strengthened design review, strengthened equipment selection, professional ordering and equipment supervision, so as to ensure high quality requirements of equipment.
