CO2 Dehydration Unit (Molecular Sieve)

• TI-CDH-M-500 – two-tower molecular-sieve dryer for 150–600 tonnes a day.
• Regeneration options – a heated slip-stream of dried CO2, or regeneration gas to client specification.

• Capacity: typically 150–600 tonnes of CO2 a day, or to client specification
• Drying: two molecular-sieve towers with thermal-swing regeneration
• Outlet water content: down to ppm level, to the pipeline specification or client specification
• Operating pressure: to suit the compression stage or tie-in, or to client specification
• Materials: stainless steel for wet CO2 service, or to client specification
• Vessels: designed to ASME VIII or client specification
• Controls: PLC with automatic tower switching, moisture monitoring and alarms

Wet CO2 corrodes carbon-steel pipelines and can form hydrates, which is why shared CCUS networks set a strict water limit at every tie-in. The dryer sits after the capture plant or between compression stages at gas processing, hydrogen, ammonia, refinery and petrochemical sites, and at cement, steel and power plants with capture. The same unit also dries CO2 for enhanced oil recovery and industrial use.

• Continuous drying – one tower on line while the other regenerates.
• Deep drying – molecular sieve takes water down to ppm level.
• Pipeline protection – dry CO2 prevents corrosion and hydrate formation downstream.
• Automatic sequence – the PLC switches towers and runs regeneration without operator action.
• Confirmed quality – the moisture analyser checks the dried CO2 before it leaves the unit.

• CO2 Quality Analyser System for CCUS – checks water, O2 and H2S in the dried CO2 at the tie-in.
• Gas Dehydration Skid (TEG / Molecular Sieve) – the equivalent dryer for natural gas.
• Filter Separator and Coalescer Skid – removes free liquid ahead of the dryer.
• Chemical Injection Skid – chemical dosing at CO2 injection wells.
