The Field Asphaltene
Test Rig is a side stream system - that means it is connected in to the crude
oil process at a suitable sample point.
The flow through the Test Rig
is at full line pressure and temperature and can therefore be returned
downstream back into the main oil line. The flow is passed through a series of
inline filters and any asphaltene build-up is monitored using sensitive inline
pressure gauges fitted upstream of each filtration device. The volume of sample
flowing through the sidestream is measured on the inline flow meter. Filters
can be later removed for observation and weighing purposes.
The Test
Rig therefore can provide valuable data on the amount of asphaltenes being
produced at any given period or production scenario; to select the most
appropriate inhibitor and optimise treatment rates to provide the most
economical chemical use.
Asphaltene precipitation may occur in
crude and condensates from reservoir to process system as the hydrocarbon
pressure is reduced, upon co-mingling fluids, addition of lift gas or
application of incompatible chemicals.
Precipitation can seriously
affect productivity and a definition of the stability envelope (pressure /
temperature) may factor in the reservoir exploitation method.

PMACs OCT asphaltene
test cells use a dynamic flow, filtration and spectroscopic technique, which
can operate with less than 200 ml of, live crude at up to 9000 psi, measuring
and quantifying asphaltene precipitation as a function of pressure and
temperature reduction.
The equipment can be configured to also measure
adherence of asphaltenes, particle size development and performance of
inhibitors but is primarily a research aid to definition of the asphaltene
stability under production conditions.. |
