Particulate Sources

CO2 from combustion capture carries fly ash and soot. Natural CO2 wells produce formation dust. Compression generates wear particles and oil. Industrial processes create various particulates. Filtration removes solids preventing equipment damage and product contamination.

Filter Configuration

Vertical vessel with CO2 inlet, cartridge filter elements arranged for maximum surface area, filtered gas outlet, dust collection hopper with drainage, differential pressure monitoring. Multi-element design handles high flows.

Filter Media

Pleated cartridge filters rated 1-10 microns depending on application. Media materials withstand CO2 with moisture resisting corrosion. High surface area maximizes dirt-holding capacity extending service life.

Operating Pressure

Design pressure matches CO2 system typically 1-100 bar before compression or at intermediate stages. Materials rated for operating pressure per ASME Section VIII. Design accommodates pressure variations.

Material Selection

Stainless steel construction resists corrosion from CO2 with moisture. Carbon steel unsuitable for wet CO2 forming carbonic acid. Filter housings and internals in corrosion-resistant materials.

Filtration Efficiency

Removes 99%+ of particles above element rating. Protects compressors from abrasive wear. Prevents catalyst contamination in synthesis applications. Meets food grade CO2 purity for beverage applications.

Differential Pressure

DP transmitters monitor filter loading. Clean DP 2-5 psi increasing as elements capture solids. High DP alarm signals replacement requirement typically 15-25 psi. Automated monitoring optimizes maintenance.

Applications

Carbon capture CO2 compression protection, beverage grade CO2 purification, enhanced oil recovery CO2 supply, food processing CO2 treatment, industrial gas production, and any CO2 application requiring particulate removal.

Element Replacement

Cartridge elements replaceable during maintenance outages. Quick-opening closures enable access. Elements disposable or cleanable depending on design. Spare elements maintained for rapid changeout.

Dust Disposal

Collected dust drains to disposal system. Dust characteristics depend on CO2 source - fly ash from combustion, formation solids from wells. Proper disposal per environmental regulations.

Food Grade Requirements

Beverage CO2 requires ultra-clean filtration removing all particulates. Stainless steel sanitary construction. Elements validated for food contact. Compliance with FDA and food industry standards.

Moisture Considerations

CO2 with moisture highly corrosive to carbon steel. Upstream dehydration reduces moisture but filtration still requires corrosion-resistant materials. Proper material selection critical for service life.

System Integration

Positioned after CO2 source before compression or utilization. Protects expensive downstream equipment. Multiple filters in parallel for redundancy during element changes.

Performance Benefits

Protects compressors and equipment from abrasive particulate damage. Meets CO2 purity specifications for food and industrial use. Extends equipment life through contamination control. Simple proven filtration technology.

Construction Standards

Pressure vessels per ASME Section VIII. Materials for wet CO2 service. Filter elements per manufacturer specifications. Complete documentation with filtration efficiency data and material compatibility.
