DEVICE, METHOD AND SYSTEM FOR PRODUCTION OF GRANULAR CARBON DIOXIDE Russian patent published in 2021 - IPC C01B32/55 B01J2/00 B29C43/00 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to production of granular solid carbon dioxide (CO₂). In particular, disclosed are a device, method and system for producing granular solid carbon dioxide. Obtained granular solid CO₂ can be formed into structures, such as granules, briquettes, suitable for packing and further processing, or for end use. Proposed device comprises housing with inner chamber to make chamber. It comprises casing surrounding casing to make chamber for liquid CO₂. Also includes multiple filter elements, each of which has section located in chamber for liquid CO₂, and pressing element.

EFFECT: group of inventions provides reduced power consumption, improved efficiency and overall efficiency of the process of producing granular solid CO₂, reduced wear of device components, particularly reduced wear of the pressing element of the device, reduced force required for pressing, obtaining granulated solid CO₂ with improved characteristics of heat insulation of components of the device.
