Carbon dioxide recovery liquefaction unit

Carbon dioxide recovery liquefaction unitProcess Technology

Methanol cracking tailGas based liquidCO2 can be divided intothreeThe major process, namelycompressprocess、drying processand CO2

Liquefaction and DistillationProcess,The buyer of the compressor unit needs to purchase it themselves, and the gas is compressed to2.7MpaAfter being dried by a drying pry, it is then subjected to refrigeration liquefaction distillation pry to obtain three nines of liquid carbon dioxide, and finally exported to the buyer's carbon dioxide tank area. Drying device pry and refrigeration liquefaction distillation device pry, respectivelyadoptPLCcontrol，And two setsPLCAll controls have on-site touch screen display and reserved features485Communication interface transmission toproperty ownerDCSSystem communicationfunction.For the convenience of system integration, the control components provided by the seller must use Siemens brand.

Dehydration liquefaction distillation pryfloor area

area covered:Approximately long20m xwide3m（Adjacent to the methanol hydrogen production unit）.

Boundary conditions and division of labor interface

Boundary conditions

The pipeline support cables inside the dehydration liquefaction distillation pry are the responsibility of the seller. The buyer is responsible for the connection of external process pipelines and public engineering pipelines such as water and gas, and is responsible for leading power and control cables to the junction box inside the pry.

Division of labor interface

（1） The seller is responsible for providingofA high-quality product that meets national and industry standards.

（2） The seller is responsible for the configuration and debugging guidance of the control system.

（3） The seller is responsible for providing on-site installation guidance, debugging, training and other technical services.

（4） The seller providesDehydration, liquefaction and distillation of carbon dioxideCivil engineering design conditions for complete sets of equipment.
