EDGE
The EDGE Il Design
The EDGE Il Design
EDGE (Enhanced Deep-Grid Electrical) desalters and dehydrators utilize a unique technology that provides the
most effective solution for removal of contaminants such as sodium, calcium and magnesium chloride from
crude oil. If not removed, these salts will hydrolyze to form hydrochloric acid which is the primary cause of
corrosion failures within crude unit equipment.

EDGE desalters/dehydrators utilize AC-type electrostatic coalescing for the efficient removal of contaminants.
Electrostatic coalescing is accomplished when the electrode grids apply a high voltage to the oil/water mixture,
forcing it to separate. As the water is washed out, so are many of the undesirable solids.

The EDGE Design
EDGE Technology is available in two different designs, the EDGE and EDGE II, which provide desalter options
for optimization to individual applications. The EDGE design minimizes transactor (electric power supply)
capacity and power consumption. The designs provide three electrified electrode grids to maximize the
desalting performances and feedstock capacity of the desalter vessel. EDGE desalters are designed to optimize
the recommended demulsifier and solids-wetting chemicals of most chemical suppliers.

EDGE II - Dependable Steady State Operation
A leader in the desalter and dehydration markets, EDGE ll is designed specifically for the treatment of the most
difficult feed stocks at higher throughput rates.
EDGE II technology provides optimized performance resulting in greater long term value:
Vessel
Transactor
The entire hydrocarbon volume of the vessel is exposed to high
voltage AC electrical fields. Four contiguous AC electrical fields
Optimized performance results from multiple transactor
secondary voltage levels that provide flexibility at varying
span from the oil/water interface to the top of the vessel.
operating conditions.
Low Intensity Field
Inlet Header
The majority of the water is separated in the first low intensity
electrical field, thereby reserving the high intensity fields for
more difficult-to-resolve emulsions. This minimizes the water
content in the high-intensity electrical field, thus reducing power
Even distribution of the oil/water emulsion across the entire
vessel length produces a laminar profile. This emulsion is injected
just above the oil/water interface, thereby maximizing crude oil
consumption.

Effluent Water Header
High Intensity Field
This field provides for the removal of final traces of water from
the crude, improving performance. Increased depth of the high
intensity fields provides excellent coalescence of small and highly
emulsified water droplets.
This header withdraws water and some solids along the entire
length of the vessel, thus maximizing water-phase residence time
and reducing the oil content of the effluent water.
