The critical point of carbon dioxide is 7.38MPa at 31°C, and the carbon dioxide at this time is in a state of neither gas nor liquid. Supercritical carbon dioxide has special properties: low viscosity, high density, strong swelling and diffusion capacity for polymers, safe, non-flammable and explosive, non-toxic and non-corrosive. The special properties of supercritical …
With the development of modern aerospace power systems towards high thrust ratio and high flight Mach number, the thermal load on the engine increases sharply. In order to guarantee the reliability and longevity of the engine, the development of rapid active cooling technology is crucial. The microchannel heat exchanger is considered to be an ideal …
Hydrogen:Hydrogen is an energy carrier, not an energy source, and can transport or store large amounts of energy. Hydrogen can be used in fuel cells to generate electricity, generate electricity or provide heat. Hydrogen is a clean secondary energy carrier, which can be easily converted into electricity and heat with high conversion efficiency and has …
(Five advantages of microreactor due to its characteristics:) A small amount of reagents reduces the costWhen the microreactor is used for the inspection of material properties or the study of chemical processes, very few reagents can be realized. This significantly reduces the cost, and at the same time, more accurate physical and chemical properties can …
Micro-chemical technology usually includes systems such as micro-heat exchange, micro-reaction, micro-separation and micro-analysis, of which the first two are more important. Micro-chemical technology starts from the source of chemical preparation process and equipment, and takes advantage of the strong improvement in mixing (mass transfer) and heat transfer of micro-channel reactors, as well as the advantages …
In the early 1990s, the research on micro-chemical technology started abroad. The United States, Germany, Britain, France, Japan and other developed countries have successively carried out research on microchemical engineering and technology. According to incomplete statistics, there are currently more than 50 suppliers of micro-chemical technology and equipment in the world, of which Europe accounts …

PCHE is suitable for power generation cycle system under high temperature and high pressure For supercritical CO2 power generation systems: The heat exchange of the current supercritical carbon dioxide test loop mostly uses a printed circuit board heat exchanger (PCHE), which is suitable for high working temperature and high working pressure, and has good expansion …
Process flow:The raw material hydrogen enters the cold box, is pre-cooled by the primary heat exchanger HX-1 pre-cooled by cold nitrogen, and then enters the secondary heat exchanger HX-2 pre-cooled by liquid nitrogen for cooling, and then enters the primary positive heat exchanger soaked in liquid nitrogen. Parahydrogen converter for constant temperature conversion. The converted …
