I. Market Pain Point Analysis

  1. Complex and Variable Shale Gas Compositions
    • Shale gas compositions vary significantly across different blocks, with methane content fluctuating widely (65%-95%).
    • Contains large amounts of impurities such as nitrogen and carbon dioxide, leading to poor adaptability of traditional equipment.
  2. Severe Fluctuations in Production Pressure
    • Shale gas well pressure rapidly depletes from 8.0MPa to below 0.5MPa.
    • Conventional equipment struggles to operate stably over a wide pressure range.
  3. Low Energy Efficiency Utilization
    • Shale gas extraction consumes high energy, while traditional pre-cooling equipment has low energy efficiency ratio.
    • Pressure energy is not effectively recovered and utilized.

II. System Process Flow

Intelligent Four-Stage Pre-Cooling System:

  1. Pressure Energy Recovery Stage
    • High-pressure shale gas (≤8.0MPa) enters the expander power generation unit.
    • Pressure energy is recovered, and the gas is pre-cooled to an intermediate temperature.
  2. First-Stage Deep Pre-Cooling
    • Expanded gas enters the plate-fin main heat exchanger.
    • Heat exchange with the refrigerant cools the gas below the dew point.
  3. Heavy Hydrocarbon Separation Stage
    • Pre-cooled gas enters the high-efficiency separator.
    • Heavy hydrocarbon components (C3+) and condensed water are separated.
  4. Precise Temperature Control
    • PLC intelligently adjusts system parameters.
    • Ensures the outlet temperature remains stable within the range of 2-15℃.

III. Working Principle

Adaptive Refrigeration Technology:

  • Adopts mixed refrigerant cycle to automatically adapt to changes in gas composition.
  • Integrates pressure energy recovery system to improve overall energy efficiency.

Intelligent Control Algorithm:

  • Adjusts operating parameters based on real-time gas composition.
  • Pressure adaptive control ensures stable operation over a wide pressure range.
  • Anti-freezing and anti-clogging early warning and protection system.

IV. Core Advantages
