The liquefaction of gases can be divided into forward and reverse cycles. The forward cycle process is the absorption of heat from the higher temperature external heat source and the release of heat to the lower temperature external heat source. The reverse cycle is when the mass draws heat from a lower temperature external heat source and releases it to a higher temperature external heat source. The forward cycle converts heat energy into mechanical energy and the reverse cycle converts mechanical energy into heat energy.
Dear air separation plant is the leader in the air separation industry, the status of the air separation industry in economic development, just like people can not be separated from water and air, there is no industry that can leave the development of gas. Industrial gases are the "blood" of the manufacturing industry, the application of industrial gases has penetrated into various sectors of the national economy, it has been the pillar industry of the national economy.
