Designed to simulate a full-scale field separation unit the MFS-200 operates from
atmospheric pressure up to 2,000 psig and temperatures from 40 °F to 200 °F.
The MFS-200 is used to determine the optimum conditions for field separation
by calculating the changes in Formation Volume Factor and gas-oil ratios with relation
to changes in separator pressure and temperature. The complete system comprises
two high accuracy gasometers for gas volume determination, high accuracy digital
pressure transducer, high pressure mercury pump, temperature controlled bath with
high accuracy digital circulating pump and variable pressure piston.
In the field, reservoir fluid at an elevated state of pressure and temperature flows
from the well head into the field separator which is at a lower temperature and
pressure and is separated (flashes) into its liquid and gas phases. The liquid phase
is then flows into a stock tank at ambient pressure and temperature and evolves
dissolved gases to form two phases. The MFS-200 Multi- Phase Flash Separator simulates
this process in the laboratory and can be used to measure the volume of gas liberated
at each stage. Samples of the liberated gas can be taken at each stage and analyzed
for composition and specific gravity. At the completion of the test the liquid,
equivalent to the stock tank liquid can be analyzed for composition and specific
