Abstract:
Crude oil emulsions occur in many stages during oil production
treatment. The main task in oil and gas production is to separate the gas,
oil and water phases and to treat the individual phases in order to meet the
product specifications.
Methods currently available for demulsification can be broadly
classified as chemical, electrical, thermal and mechanical (gravity
separations). Demulsification (emulsion breaking) is necessary in many
practical applications such as the petroleum industry. Chemical
demulsification is the most widely applied method of treating water-incrude
oil emulsions and involves the use of chemical additives to
accelerate the emulsion breaking process. The effect of chemical
demulsification operations on the stability and properties of water-incrude
oil emulsions was assessed experimentally. In this regard,
demulsifier was used. Mechanical (gravity separations) method also is the
most widely applied method of treating crude oil –in- water emulsions
and involves the use of CPI separator to accelerate the emulsion breaking
process.
In the present work and for Demulsification method, Demulsifier
type (KS-5038) was used (injected) for dehydration for Neem Field
Processing Facility water in oil emulsion. The experimental work was
performed for crude oil samples (daily) after chemical injection.
Mechanical method (gravity separation) also was applied to separate the
oily water emulsion to enhance the produced water quality according to
WHO specification and reduce the oil waste with water.
The present work involved in this thesis by uses two
demulsification methods which have been studied, discussed and
compared with successful Neem FPF laboratory test results that obtained
good and satisfied result.
