Thailand’s PTTEP has selected US contractor Honeywell as the carbon capture technology provider for the Arthit carbon capture and storage project at its producing Arthit gas field in the Gulf of Thailand.
Honeywell will also provide engineering and consultancy services for front-end engineering and design for the Arthit CCS scheme and subsequent phases of the project, subject to a successful financial investment decision. The company will also supply its Separex membrane elements for this project as well as providing pre-commissioning and start-up support in future.
PTTEP chief executive Montri Rawanchaikul recently told Upstream that the company is planning to sanction the Arthit CCS project in 2023.
Honeywell noted that its Separex membrane technology will help to achieve Arthit’s project objectives to concentrate the carbon dioxide-rich stream, which will be geologically stored in depleted reservoirs.
This project will be one of the largest commercial installations for Honeywell’s Asia-Pacific region and will demonstrate the successful adoption of commercially available natural gas processing technology for a CCS application, the company said.
“Today, 15 million tonnes per year of CO2 is being captured and used in storage/utilisation applications through Honeywell’s CO2 solutions process expertise. We currently have the capacity to capture 40 million tonnes per year through our installed projects worldwide,” said Matt Spalding, general manager of Honeywell UOP Asia Pacific.
“This award builds upon our long-standing relationship with PTTEP and through expanding upon our installed CO2 capture technology we are pleased that this provides an optimal solution for the Arthit CCS project.”
Honeywell said its technology provides a solution to revamp the existing system to concentrate the CO2-rich stream using a two-stage process so that it may be injected into a nearby depleted gas reservoir while considering the constraints of the offshore platform.
The technology also enhances hydrocarbon recovery that would otherwise be flared, thereby providing additional hydrocarbon production and adding value to the project beyond the carbon capture, the company added.
