Description

Full-component Analysis for Custody Transfer Grade Gas Quality

It analyzes all components of natural gas in real time and automatically calculates heating value, density and Wobbe index in accordance with international standard algorithms for pipeline custody transfer metering.

Long-term On-site Monitoring with Low Power Consumption

Its ultra-low power design fits remote unattended well sites and vehicle-mounted portable testing units, capable of continuous operation powered by 12 V vehicle DC supply.

Comprehensive Diagnosis and Auto-calibration

It adopts dual electronic carrier gas pressure regulation and real-time monitoring of oven temperature sensors. The detector will not be damaged in case of carrier gas shortage, extending calibration intervals and lowering operation and maintenance costs.

Data Traceability and Auditing

Complete event logs, fault alarms and archived historical chromatograms are provided to meet traceability requirements for oil and gas metering supervision.

Multi-stream Expansion

It supports switching between single-stream and multi-stream sampling to conduct alternating analysis for multiple natural gas pipelines.

Typical Application Scenarios

  1. Gas quality monitoring and reserve evaluation at upstream gas wellheads and gathering stations
  2. Custody transfer metering for long-distance transmission pipelines, distribution gate stations and gas storage reservoirs (core application)
  3. Gas quality supervision at LNG receiving terminals and urban gas pressure regulating gate stations
  4. Heating value optimization and regulation for gas-fired power plants and self-contained gas facilities in chemical plants
  5. Mobile gas quality inspection vehicles and temporary emergency gas quality testing (portable version)
