The production process,technical characteristics and equipment of flexible polyurethane foam using liquid carbon dioxide as physical foaming agent were introduced.

Through hydrocarbons combustion,carbon dioxide purification to produce liquid carbon dioxide is an alternative for those regions being devoid of carbon dioxide sources.

In order to maintain the freshness,color,deliciousness and flavor of foods,the carbon dioxide fast freezing machine has been developed on basis of liquid carbon dioxide spray refrigerating principle,and food may swiftly pass through the ice crystal band by using this machine.

Thermodynamic behavior and solubility enhancement of carbon dioxide expanded liquids

By improving startups and shutdowns method and adding a stripper, the process gas condensate and carbonate dioxide condensate from purification section of ammonia plant are properly treated, thus ensuring the environmental protection recovery, recycling usage and energy economizing.

Applications of blast in well combined with flushing well by liquid carbon dioxide;
