Oxygen-enriched combustion exhaust volume for large air separation plant
Oxygen-enriched combustion exhaust volume for large air separation plant
Oxygen-enriched combustion blows in less air and therefore takes away less heat after combustion. As the oxygen enrichment increases, the exhaust gas is gradually reduced, the amount of flue gas is reduced and the heat loss is reduced.
Products of Oxygen-enriched combustion exhaust volume for large air separation plant
In the field of modern coal chemical industry, the air separation plant mainly provides oxygen and nitrogen. Oxygen is mainly used as gasification agent and reaction raw material, while nitrogen of different pressure levels is used as raw material nitrogen, inertia protective gas, pneumatic conveying gas and purging gas. In the past, air, oxygen-enriched or low-pressure pure oxygen were basically used as gasification agent in the domestic coal chemical industry, and the gasification efficiency, carbon conversion rate and gasification furnace capacity were all very low
In other fields of chemical industry, the demand for air separation plant is stable. In response to the production demand of customers, both parties cooperate on the 2000/3600 type project of small air separation plant, it can solve the problems of customer's raw material pretreatment, delayed coking unit and comprehensive utilization.
Isothermal throttling refrigeration in large air separation plant
Air can be reduced in temperature by throttling, isothermal throttling is an isoenthalpy process and does not produce cooling. If the gas is to be cooled by isothermal throttling, it is compressed by isothermal compression and expanded by throttling. The enthalpy of the gas decreases during isothermal compression and the work of the compressor and the enthalpy drop of the gas are transferred to the environment together as...
All pressure vessels, valves and piping of small air separation unit and the vicinity of the piping (in contact with oxygen or cryogenic media) must be clean, dry and free from oil and grease before installation. Equipment that has been degreased by the manufacturer and is not contaminated can be installed without degreasing; if it is contaminated with grease, it should be degreased.
materials such as aluminium and ma...
