Type 8000/2000-240 solution for small and medium-sized air separation plant in circular economy industry
Circular economy is also characterized by resource conservation and recycling, which is a harmonious economic development mode with the environment. All materials and energy can be used reasonably and persistently in this continuous economic cycle, in order to reduce the impact of economic activities on the natural environment as small as possible. As an emerging industry, the market development in the future is inestimable.
2400/1000-type solution for small and medium-sized air separation plant in nonferrous industry
Formulate construction guidelines for non-ferrous metal intelligent mines and factories, and guide the construction of industry intelligent standardization. Reducing production energy efficiency and overall controllable cost, promoting the rapid iteration of production equipment and improving enterprise profits are the problems that need to be solved urgently in current industry. Recently, DEAR air separation cooperated with customers and signed a 2400/1000-type small and medium-sized air separation plant project, which was highly recognized by customers through reasonable scheme design.

A low pressure nitrogen expander is added to the process design. The pressure nitrogen from the pressure tower and high pressure expander is expanded into low pressure nitrogen, which is combined with the nitrogen coming from the low pressure tower and fed into the charge gas compressor. This is specially set up for rapid oxygen load changes. The oxygen product flow rate during normal operation corresponds to the amount of oxygen contained in the amount of air entering the air separation unit. T...

The load adjustment range of low pressure small air separation unit is related to the adjustment performance of the raw material compressor, the adjustment performance of the expander, the structural characteristics of the distillation tower and other factors. At present there are imported guide vane of the turbine air compressor flow adjustment range in 75-100%; adjustable nozzle of the turbine expander adjustment range can be in 65-100%. When oxygen is rich and the need to reduce oxygen produc...
