Sampling and Analysis Systems

Pracsi Group recognizes that transfer of hydrocarbons involves multi-million dollar transactions and therefore maintaining accuracy of measurement to ensure fiscal accountability is of paramount importance.

Accurate measurement of hydrocarbons is dependent on the accuracy of the flowmeter itself but also the quality and properties of the product. Density, water content, viscosity and composition are properties which are taken into consideration in calculating the value of the product and the selection of materials and metering techniques. This highlights the necessity of accurate sampling and analysis systems. The design and manufacture of Sampling and Analysis systems is governed by national and international standards that address proven techniques for the collection of representative product samples.

Pracsi designs and supplies this ancillary equipment as part of the integrated metering system.

Gas Sampling and Analysis Systems comprise of:

  • Gas conditioning equipment including sample probe, filtration and pressure reduction while maintaining the sample temperature.
  • The gas analysis instruments, such as, chromatographs, hydrocarbon dew point meters, water in gas monitors, relative density meters and Hydrogen Sulphite analyzers.
  • Fully equipped temperature controlled and air conditioned or freely ventilated analyzer houses where the gas conditioning and analysis equipment is installed.

Liquid hydrocarbon Sampling and Analysis Systems comprise of:

  • Sample mixing equipment which may be of proprietary or custom design
  • Sample probe and fast loop pump
  • Sampler and sample receivers
  • Densitometer
  • Water in Oil Meter
  • Viscometer
  • Heated enclosure for the sampler and sample receiver.

  • Process Control Systems

    Advanced Process Control Systems and Strategies. Systems are turn-key encompassing engineering design, procurement, manufacturing and installation commissioning.

  • Ultrasonic Metering Systems

    PrACSI Group supply turbine meters for use in refineries and petrochemical plants and because they are easy to calibrate in situ they are also used as master meters for liquid ultrasonic metering systems.

  • Metering control systems

    Metering control systems comprising flow computers, supervisory computer, PLC where applicable and auxiliary control equipment are integrated into a custom designed metering control panel.
