Large Scale Amine Carbon Capture and CO2 Sequestration Facility
Up to 2.2 BCF Gas Treatment Facility
- Initial build-out of 1.7 BCF processing capacity, including H₂S and CO₂ removal and dehydration systems.
- Deep CO2 Removal with two 4,000 GPM amine trains.
- 400 MMSCFD of residue gas compression using two electric drive single-stage compressors.
- CO₂ sequestration system designed to handle 2 million metric tons per year at full buildout, ensuring safe capture and pipeline export.
High-capacity treatment and compression systems to enable efficient, low-carbon production
The initial build-out established a robust 1.7 BCF processing capacity designed for H₂S and Deep CO₂ removal, along with dehydration. The facility’s acid gas removal process utilized two 4,000 GPM amine trains for high-efficiency treatment. Additionally, the scope included 400 MMSCFD of residue gas compression through two electric drive single-stage compressors to support downstream delivery. A dedicated CO₂ CCU (carbon capture and use) system was also installed, which compresses, dehydrates, removes H₂S, and filters CO₂ before routing it safely to an export pipeline — supporting emissions reduction and long-term sustainability goals.
Driving Success Through Collaborative Expertise and the Right Technology Solutions
LDIS supported the Gillis project by designing the overall gas treatment process, selecting the right technologies to remove CO₂, H₂S, and water while optimizing efficiency and cost. A key achievement was integrating carbon capture by identifying and applying the most effective technology to capture and prepare CO₂ for sequestration or reuse. By ensuring the system was seamlessly incorporated into the main treatment plant and fully compliant with environmental standards, LDIS helped deliver a safe, sustainable, and future-ready solution. This success reflects our collaborative, multi-discipline expertise—bringing together process, mechanical, piping, structural, electrical, instrumentation, procurement, and project management to achieve lasting client value.
Client Benefits:
- Lower carbon footprint and environmental impact with integrated CO₂ CCU
- Reliable and efficient compression for consistent residue gas delivery
- Future-ready infrastructure supporting regulatory compliance and sustainability commitments
- Leveraging the right technologies and engineering strategies to optimize project investment and reduce unnecessary expenditures
