Crude Oil Measurement and Quality Systems

Crude Oil Measurement and Quality Systems (COMQS) are automated complexes designed for commercial and operational crude oil accounting. They measure mass or volume, as well as physical and chemical quality parameters (density, water content, viscosity) in real time. COMQS provide high measurement accuracy in pipelines, utilizing process skids, quality measurement modules, and data acquisition systems.

Main Components of COMQS:

• Metering Skid (MS): Measures crude oil flow rate using turbine, Coriolis mass, or vortex flowmeters.
• Quality Measurement Skid (QMS): Determines density, viscosity, water content, and other parameters.
• Data Processing System (DPS): An automated control system that collects and processes data.
• Connection Point for Stationary or Mobile Proving Unit: Used for flowmeter calibration.

Advantages and Purpose:

• Automation: Fully automated measurement without operator intervention.
• Accuracy: Enables precise commercial fiscal calculations.
• Real-Time Data: Provides immediate access to measurement data.
• Integration: COMQS typically integrates a quality measurement skid, a metering skid, and a controller. COMQS ensure accurate accounting of commercial crude oil during pipeline transportation and are used at refineries, oil terminals, and oilfields.
