Gas Liquids Engineering Ltd. (GLE) completed a FEED study for carbon capture and sequestration project at an ethanol plant in central Canada. The facility produces ethanol by fermentation, with 120000 tonnes per year of CO₂ formed as a normal fermentation byproduct. The client plans to capture this CO₂, compress it, and inject it for permanent sequestration into an on-site disposal well. A future option of transporting the CO₂ offsite via pipeline for use in an Enhanced Oil Recovery (EOR) scheme is also being evaluated as part of the FEED.
Project highlights include:
- Tie-in of CO₂ from the existing Ethanol Absorber
- New multi-stage blower to boost CO₂ pressure and an aftercooler
- Piping and pipe supports from the existing Production building, to the new CO₂ compression facility, and to the injection wellhead.
- New 5 stage reciprocating CO₂ injection compressor
- Tie-ins for various utilities
- New MCC Building including:
- DCS Panel
- 600 – 120VAC UPS
- 600VAC Motor Control Center (MCC)
- 12.47 kV – 4160 VAC VFD for CO2 Compressor motor
- Fire Alarm Panel
- 600VAC – 120/208 Transformers with VAC120/208 Distribution Panels
- Communication Rack for Fiber and Ethernet
- Expansion of the existing DCS control system into the new CO2 sequestration facilities
- Upgrades to the existing cooling water system including the install of a new 125 hp pump controlled by a new VFD
