Fluid Analysis

 Understanding the problem

Originating from many sources, oilfield waste streams vary widely in composition and physical properties.

The starting point of every separation process is to understand the composition of these waste streams, these can be:

• Contaminated waters  

  • Produced water 

  • Slops

  • Oily waters 

  • Completion fluids  

• Contaminated fuels 

  • Bunkered diesel fuels 

  • Day tanks 

• Contaminated oils 

  • Hydraulic oils  

  • Lube oils 

  • Refinery oil sludges 

At OSSO, our in-house technical consultants have decades of expertise and knowledge to propose a laboratory testing programme ahead of the design and optimisation of the separation process. Laboratory testing routinely carried out includes but not limited to:

• % Suspended solids 

• Particle size distribution 

• Oil-in-waters 

• pH 

• H2S 

• BOD (biochemical oxygen demand) 

• COD (chemical oxygen demand) 

With the analysis results as our starting point, we can then test the waste streams in our laboratory centrifuges.

Laboratory centrifuge spin tests

The Hot Spin centrifuge is a specially built laboratory test tube centrifuge enabling separation at temperature up to 100 degrees C. Using this equipment, it is possible to simulate the effect of mechanical separation by decanter or disc stack centrifuges and from the results we can:

• Ascertain whether the product can be separated by centrifugal force at a given temperature

• Choose the appropriate full-scale equipment

• Predict performance and capacity and optimise process conditions
