The throttling of gases is a process of equal enthalpy, i.e. throttling is simply a transformation between the internal energy of the gas and the work of propulsion, which includes internal potential energy and internal kinetic energy, while the temperature of the gas is only related to internal kinetic energy. The pressure of a gas is reduced after throttling, its mass volume increases and its internal potential energy always increases. When the flow energy becomes larger, the temperature of the gas decreases, when the flow energy decreases, its absolute value is greater than the increase of the internal potential energy, the temperature of the gas increases when it is throttled.
The intelligent production workshop and production equipment and ancillary facilities of Dear Air Separation small air separation unit and large air separation plant serve as the production base of the Technology Centre, giving priority to the arrangement of research and development production to ensure the smooth implementation of scientific research projects and issues and to promote the rapid, sustainable and coordinated development of the company.
