In the energy sector, the efficient utilization of natural gas resources, especially in remote areas without pipeline infrastructure, poses a significant challenge. The Shanxi Zhonglian Coalbed Methane Gas Well Liquefaction Project, undertaken by Kaitian Gas, offers an innovative and effective solution to this problem.

Project Background: Remote Gas Wells and the Challenge of Commercialization

Zhonglian Coal's gas wells are located in a remote region of Shanxi Province, China, far from any pipeline infrastructure. This makes traditional gas recovery methods not only inefficient but also economically unviable. For Zhonglian Coal, the key challenge was finding a way to commercialize natural gas resources during the early stages of exploration. They urgently needed a solution that could be rapidly deployed and flexibly adapted to liquefy gas directly at the wellhead, overcoming the bottleneck of developing remote gas sources.

Kaitian Gas's Solution: Mobile Liquefaction Unit for On-Site Processing

To address these challenges, Kaitian Gas designed and manufactured a mobile natural gas liquefaction unit specifically for Zhonglian Coal. This system boasts several key features:

Skid-Mounted Integration and Flexible Modules

The liquefaction unit adopts a skid-mounted integrated design with flexible modules. This design allows for easy transportation and quick installation at the wellhead. Its compact size and integrated systems make it highly adaptable to various wellhead environments, ensuring that it can be deployed even in the most remote and challenging locations.

Low Energy Consumption and High Efficiency

The unit is designed for low energy consumption, making it both environmentally friendly and cost-effective. It can efficiently cool and liquefy natural gas at the wellhead, enabling on-site processing and subsequent transportation of the liquefied gas. This not only reduces the need for extensive pipeline infrastructure but also minimizes gas loss during transportation.

Successful Commissioning and Stable Operation

The mobile liquefaction unit was successfully commissioned in June 2015. Since then, it has demonstrated stable operation and excellent performance. The unit has consistently achieved a liquefaction capacity of 30,000 Nm³/day, providing a reliable solution for the client's natural gas processing needs.

Technical Highlights: Innovation and Efficiency in Liquefaction Technology

The project showcases several technical highlights that contribute to its success:

Mobile Liquefaction Module

The mobile liquefaction module is particularly suitable for on-site recovery of unconventional resources such as coalbed methane and shale gas. Its flexibility and mobility make it an ideal solution for remote gas wells where traditional pipeline infrastructure is lacking.

Integrated "Extraction-Liquefaction-Transportation" System

The project establishes an integrated system that connects the extraction of natural gas with its liquefaction and subsequent transportation. This system completes the crucial link between exploration and commercialization, enabling efficient resource utilization and value creation.

Highly Integrated Skid-Mounted System

The skid-mounted system is highly integrated, making it easy to relocate and deploy. It can be quickly set up at different well sites, providing a flexible and efficient solution for natural gas processing in remote areas.

Immediate Compliance and Short Commissioning Period

The liquefaction unit ensures immediate compliance with relevant standards and regulations. Its short commissioning period greatly reduces the time from construction to gas recovery commercialization, allowing clients to start benefiting from the project sooner.

Project Value: Setting a Benchmark for Non-Pipeline Natural Gas Development

The Shanxi Zhonglian Coalbed Methane Gas Well Liquefaction Project has achieved remarkable results and demonstrated significant value:

Benchmark for Non-Pipeline Natural Gas Development

The project successfully achieved stable liquefaction of 30,000 Nm³/day of natural gas, setting a benchmark for non-pipeline natural gas development. It provides a reference case for other regions facing similar challenges of remote gas resource utilization.

Early Commercialization of Gas Sales

By enabling on-site liquefaction, the project allowed Zhonglian Coal to commercialize gas sales during the early exploration phase. This improved resource conversion efficiency and provided sustainable business returns for the client.

New Operational Model

The project established a new operational model of "Extraction → Wellhead Liquefaction → End User." This model offers significant replicable value for other remote gas well projects, providing a viable path for non-pipeline natural gas utilization.

Reference for Remote Wellfield Development

The experience gained from this project has served as a valuable reference for the development of multiple remote wellfields. It has provided insights and guidance for other companies and regions facing similar challenges in natural gas resource development.

Conclusion

The Shanxi Zhonglian Coalbed Methane Gas Well Liquefaction Project is a testament to Kaitian Gas's technical expertise and innovative approach to solving complex energy challenges. By deploying a mobile liquefaction unit with advanced technology and design, the project has successfully unlocked the potential of remote natural gas resources. It has not only provided a sustainable solution for Zhonglian Coal but also set a benchmark for non-pipeline natural gas development worldwide. As the demand for efficient and environmentally friendly energy solutions continues to grow, this project serves as an inspiring example of how innovation can drive progress in the energy sector.
