Deep cold air separation technology

The site should be carefully checked for the chiller type and evaporator design pressure. It is not possible to use the water inlet as a water outlet and vice versa: the water flow switch is determined to be installed. The first start-up must be carried out under the guidance of the chiller plant manufacturer's personnel. Do not power on the chiller without permission. The installation requirements of the chiller plant are reflected in the operating instructions and the chiller plant manufactur...

In order to reduce the air temperature in the low temperature air separation unit, various heat exchange equipment are needed for cold and heat exchange in various air separation systems, such as nitrogen water precooler, switching heat exchanger, main heat exchanger, condensing evaporator, subcooler, liquefier, vaporizer, electric heater, etc. These heat exchange equipments are installed in each system of the air separation unit, which are necessary for air liquefaction and gas separation. According to the principle of heat transfer, the heat exchanger of air separation unit can be divided into three types: 1. Dividing wall type: the cold and hot fluid is separated by the heat transfer wall, the medium does not directly contact in the heat transfer process, and the hot fluid transfers heat to the cold fluid through the heat transfer wall. For example, tube heat exchanger and plate heat exchanger. 2. Heat storage type: the cold and hot fluid alternately flows through the solid
