Purpose: Used to liquefy and purify crude carbon dioxide to food grade or industrial grade liquid carbon dioxide products.

Principle: crude carbon dioxide gas through fine desulfurization, drying, low temperature distillation and other purification process, to obtain qualified liquid carbon dioxide products.

Equipment composition: includes pressure system, desulfurization system, drying system, low temperature distillation system, refrigeration system, liquid storage system, safety fire system, control system, etc.

Technical features: The technology is advanced, the pretreatment process adopts advanced desulfurization and dehydration system, simple equipment, saving investment. The refrigeration system adopts the two-stage refrigeration cycle system to achieve low energy consumption; Low temperature rectification system adopts the whole cold box layout, with reliable quality, short construction period, less equipment investment.

In terms of CO2 liquefaction equipment, our company has cooperated with other companies to build a number of sets of CO2 liquefaction equipment.  The plants used In production can produce food grade and industrial grade liquid carbon dioxide products at the same time. We are capable of designing, manufacturing and constructing CO2 liquefaction equipment of up to 200,000 m3 / d.
