NATCO Electro-Dynamic DesalterField or refinery: A higher level of desalting performance

O I L

Camerons Process Systems combines

more than half a century of crude oil

dehydration and 30 years of field

and refinery desalting experience to

create a new leading edge crude oil

desalting process.

Camerons patented and proprietary

NATCOElectro-DynamicDesalter(EDD) was developed to replace the

conventional multi-staged desalting

system. The NATCO Electro-Dynamic

Desalter accomplishes this task

by providing multiple stages of

electrostatic mixing, coalescing and

settling in a single vessel allowing salt

removal and dehydration efficiencies

approaching 100%.

Five proven Cameron process

technologies were united and

conveniently combined to provide

the refining industry with the first

real electrostatic desalting design

innovation in over a decade.

The NATCO Electro-Dynamic Desalter

will provide two-staged desalting

performance without the excessive

capital investments or space

requirements common to these

systems.

When Japanese refiners embarked upon a long-awaited expansion and upgrading program , they turned to the NATCO

Electro-Dynamic Desalter for state-of-the-art desalting to give them maximum performance and flexibility in meeting future

desalting needs. Over 60% of the desalter s installed in Japanese refinerie s in the past ten years have been supplied by Cameron.

Electrostatic Fields

High Voltage Gradient Dispersion

Five Proven Cameron Technologies

1 Camerons Dual Polarity Electrostatic

Dehydrator:

The patented process applies a high

gradient, sustained DC field between

pairs of electrodes, while maintaining

a weaker AC field between the electrodes

and oil/water interface.

Results:Dramatic improvements over

conventional AC dehydration.

2 Camerons Composite PlateElectrodes:

Developed to obtain a gradual electrical

field.

Results:Coalescence of the smallest

of water droplets, while preventing

sustained arcing from highly conductive

emulsions.

3 Camerons Load Responsive

Controller:

Developed to regulate the flow ofelectrical current and to provide self-

adjusting electrical power levels for

optimization of electrostatic coalescence.

Results:Optimum salt removal over a

wide range of feed stock materials.

4 Camerons Counter Current Dilution

Water Process:

Developed to increase dilution water and

produced water contact.

Results:Reduced dilution water rateswhile providing maximum desalting

efficiency.

5 Camerons Electrostatic Mixing

Process:

Incorporated to provide multistage

dilution water and brine mixing.

Results:Mixing efficiencies approaching

100% while enabling the user to reduce

dilution water volumes.

Increase operating efficiency while reducing operational expenses

The NATCO Electro-Dynamic Desalter, under a variety of conditions, can:

Retrofit your single-stage system to two-stage desalter

performance

Increase the levels of salt removal over any other single-vesselprocess

Double the capacity of two-stage systems

Reduce initial capital costs for new installations

Allow higher inlet water cuts during upset conditions while

maintaining specified effluent requirements

Improve effluent water quality

Allow for greater operational flexibility by handling a wide

range of feed-stocks

Decrease chemical consumption Improve mixing efficiency

Reduce dilution water requirements

Increase salt removal efficiency

Require less space

Provide improved dehydration capabilities

Whether you are upgrading or expanding an existing facility

or designing a new installation, Camerons new and unique

desalting technology could provide you with the means to

minimize installation costs and to substantially reduce operating

expenses.

Multistage Efficiency Through a Single Vessel

A proven example of the EDD technology by integrating the

five technologies listed on the front page, the typical situation

below involves a flux of 100 BBL/Day and CSA with a crude rise

rate of 0.08 inches/second. The NATCO Electro-Dynamic Desalter

would retain crude oil within the grid section for 188 seconds and

provides nine extraction cycles of mixing/coalescing/settling at a

rate of 21 seconds per cycle. The mixing phase shown is at 35,000

volts. The coalescence phase is shown as the degrading field

responds to the voltage reduction. The settling phase is shown

with the voltage at 16,000 volts.
