A Gas Conditioning Unit plays a vital role in preparing natural gas for power generation and steam production. Turbines and gas engines require precisely conditioned gas to operate efficiently and safely. To achieve these specifications, specialized gas treatment units are used to remove impurities, control pressure, and ensure a stable gas supply.
How a Gas Conditioning Unit works
The process begins with natural gas from a main pipeline feeding the gas purification unit. The gas enters the gas conditioning package through the supply inlet pipeline and passes through a Shut Down Valve (SDV). This valve can isolate the main inlet of the plant in case of emergencies.
1. Knock-Out drum for condensate removal
After the main inlet, the gas flows into the Knock-Out Drum skid, where free condensate droplets are separated from the gas stream. The collected condensate is transferred to the Condensate Unit for safe disposal via tank truck.
2. Filter Separators for particle and droplet removal
Gas leaving the Knock-Out Drum enters one of two filter separators (one active, one standby). These coalescing filter elements capture small particles and additional condensate droplets. The separated liquid is collected in a sump and drained to the Condensate Unit for disposal.
3. Flow metering and gas analysis
Downstream from the filters, the gas flows into the Flow Metering skid. Here, one of two metering lines measures the gas flow rate. A permanently installed Master meter allows for accurate calibration. The Z-configuration enables inline calibration of the duty flow meter.
Upstream of this skid, a GasPT or gas chromatograph unit provides detailed gas analysis, including calorific value and Wobbe index. This data is sent to flow computers in the local control panel for precise monitoring.
4. Pressure reduction and final delivery
Next, the gas enters the Pressure Reduction station skid, where it is reduced to the required set pressure. From there, it flows through the common outlet towards the turbines. Another Shut Down Valve at the outlet ensures the plant can be isolated during an emergency shutdown.
Benefits of a well-designed Gas Conditioning Unit
A properly engineered Gas Conditioning Unit ensures:
- Clean, impurity-free gas for optimal turbine performance
- Reduced equipment wear and maintenance costs
- Accurate gas measurement and monitoring
- Stable pressure for consistent operation
- Improved plant safety with emergency shutdown features
