Profile: Kernow Analytical Technology (KAT) Limited includes services such as emulsion, foam, gas hydrates and rheology. Using our gas-sparging rigs foaming tendency is measured in terms of volume or height of the foam column and foam stability in terms of its collapse time. Temperature and gas flow may be altered to suit field conditions. The rate of gas release can also be measured by monitoring the change of density with time. The performance of antifoam chemicals can easily be examined by dosing the crude sample under test.
