Facility Overview
The proposed gas processing plant will be located at LSD 10-21-76-9 W6, approximately 2.3 km from the nearest residence and 0.6 km from the nearest surface development. The site falls under the Grande Prairie AER Field Centre and is designed to process sour gas volumes exceeding the 1 tonne/day sulphur threshold.
Key facility specifications include:
- Total Inlet Capacity: 4,248 × 10³ m³/d of raw gas
- Product Streams: Sales gas (3,642 × 10³ m³/d), condensate (159 m³/d), and water (159 m³/d)
- Sulphur Handling: Regenerative sweetening system with acid gas injection and 98.4% sulphur recovery efficiency
- Acid Gas Volume: 239 × 10³ m³/d, containing H₂S at 891.9 mol/kmol
- Emergency Planning Zone (EPZ): 4.41 km radius
The plant will meet all AER Directive 038, 055, 058, and 060 requirements, with no continuous flaring or incineration anticipated. Predicted sound levels meet regulatory thresholds at 40 dBA.
Power and Compression
The facility will host a combination of gas-driven and electric compressors to balance operational flexibility and emissions performance:
- 4 Gas-Driven Units (up to 3,729 kW total)
- 11 Electric Compressors, bringing total installed compressor power to 20,411 kW
This hybrid power configuration positions CSV Midstream to efficiently handle variable throughput while minimizing its emissions footprint.
Environmental and Regulatory Compliance
- NOx Emissions: 24.17 kg/h
- CO₂ Emissions: 437.2 tonnes/day
- Flaring/Venting: None reported
- Noise Compliance: Meets AER Directive 038
- Waste/Storage Compliance: Meets Directives 055 and 058
The design reflects Alberta’s evolving environmental standards for sour gas facilities, with CSV incorporating subsurface acid gas disposal and regenerative sweetening to minimize sulphur emissions.
Regional Drilling Activity
Year-to-date data show robust drilling activity in the area surrounding the proposed Valhalla gas plant. A total of 78 new wells have been drilled across the Pouce Cou, Valhalla, and La Glace fields — indicating strong upstream demand for additional midstream capacity.
