Sampling

Our systems and knowledge of sampling have developed over the years from manufacturing simple single sample receiver systems to state of the art systems with combined mixing fast-loop sampling and real-time

analysis monitors

Why Sampling

Daily crude oil demand 85 million bbls Need for accurate measuring systemsBuyers of crude oil want good sampling systems and accurate analysis to determined the product specification: – Density– Total water content– Contaminants– Composition and quality

Systems designed to custody transfer standard

Test fluids used:

Objective 1.

– Determine optimum nozzle design

Objective 2.

– Determine required power for optimal mixing in a horizontal pipeline

Objective 3.

– Determine required power for optimal mixing in a vertical line

Summary & Conclusions

Main conclusions drawn from the testing of a Power-Jet mixing system are:

– Nozzle designs affect the mixing results.

– For low water-cut, Power-Jet mixer flow rate at 25% of the calculated value provides inadequate oil/water distribution.

– Above 50% of calculated value it was adequate to distribute the free water over the cross section of the pipe at the lowest pipeline velocity of 0.2m/s.

– For high water-cut - 50% v/v - a Power-Jet mixer flow rate of 100% of the calculated value was adequate to distribute the free water over the cross section of the pipe at the lowest pipeline velocity of 0.2 m/s

– Horizontal installations with all water-cut conditions yield better results for sampling at the centre of the pipe than top or bottom.

– Sampling in a vertical pipeline provided a representative sample at all main pipeline velocities, Power-Jet mixer flow rates and water-cuts.

Representative sampling of multiphase products begins with good mixing
