Mobile LNG Integrated Unit Technology

This technology targets remote oil and gas field wells with the following characteristics: Small gas volume Unstable gas flow Far from main pipeline network Not economical for centralized recovery On-site liquefaction is the most efficient utilization method to avoid flaring, which causes energy waste and environmental pollution.

Standardized Design for Small-Scale Liquefaction Plants

We have developed standardized designs with finalized products for 5, 10, and 50 million m³/day capacities.

Through standardized design and skid-mounted production, we achieve factory prefabrication and modular construction. Equipment is assembled and commissioned in controlled environments, ensuring superior quality and significantly reducing on-site work. Complete skid units enable rapid deployment in remote areas and easy relocation for reuse, effectively lowering engineering costs and improving equipment utilization.

1. Standardized System Documentation

Our standardized system documentation comprises unified technical specifications, piping material grade requirements, process descriptions, and standardized legends for process flow diagrams and P&IDs.

2. Standardized Process Flow

Through systematic analysis of current natural gas liquefaction processes and technology trends, we have developed standardized process flows for different units based on unified process routes, automation levels, and equipment selection.

3. Standardized Layout Design

Through integrated station buildings and skid-mounted plant units, the site layout is arranged by functional zones:

Process unit area

Compressor area

Auxiliary production area

Control building

Loading area

Following the principles of skid-mounted units, integrated buildings, and functional zoning, standardized layouts are established. These layouts can be adapted and reused for different project conditions.

4. Standardized Procurement Documents

5. Standardized Skid-Mounted Production

6. Standardized Product Finalization
