Chongqing Shale Gas Wellhead Liquefaction Project

Hours

Integrated LNG System Enables Efficient On-site Resource Conversion

Project Information

  • Location: Yongchuan District, Chongqing, China
  • Liquefaction Capacity: Modular and expandable based on project requirements
  • Client: Sinopec Chongqing Shale Gas Base
  • Project Start Date: June 2022

Project Background

With PetroChina and Sinopec accelerating shale gas development in Chongqing, the Yongchuan District has emerged as a key production hub in China. Currently, Sinopec’s daily shale gas output in the region has exceeded 1 million cubic meters, with total production potential expected to reach several million cubic meters per day. However, due to the lack of mature pipeline infrastructure, conventional gas transportation methods result in high costs and low efficiency. The client urgently required a flexible and efficient wellhead liquefaction solution to enable on-site utilization and maximize resource value.

Solution

To meet the demand for efficient resource conversion at shale gas production sites, KAITIANGAS independently developed and deployed a new generation of integrated LNG liquefaction units. Based on a proven mixed refrigerant process and further optimized, the system features a compact structure, high efficiency, and strong adaptability—ideal for on-site deployment at gas wells. The modular design allows for scalable capacity expansion, significantly shortening the construction period and reducing initial investment for the client.

Technical Highlights

  • Proprietary Integrated System: A new-generation all-in-one LNG liquefaction solution compatible with complex shale gas compositions
  • Optimized Mixed Refrigerant Process: Reliable and efficient with a simplified system structure
  • Modular and Flexible Design: Capacity can be easily adjusted to match wellhead output, supporting future scalability
  • Low Operating Cost, High Economic Return: Especially suited for resource-rich regions lacking pipeline infrastructure
