Deluxe Emulsion Type Treaters are especially designed line of rugged, economical,

vertical treaters designed to give maximum performance in treating loose to moderate

emulsions where the coalescing properties of a filter section are not required.

Technical Information

How it works

The wellstream mixture of oil, emulsion, water, and gas enter the gas separation section

at the top of the treater. The inlet diverter deflects the liquid outward against the treater

shell and causes it to spread in a thin film so both free gas and solution gas are released

quickly. The oil, water, and emulsion are collected on the diaphragm plate and they then

flow through the downcomer pipe to the spreader underneath the firebox. The free-water

immediately separates from the oil and is discharged from the treater bottom section

through the outside adjustable siphon.

The oil and emulsion is broken into small streamlets by the perforated tray spreader and

moves up through the hot water section surrounding the firebox. This action breaks the

larger part of the emulsion. The water released settles to the bottom of the treater where

it is discharged with the free water. The final traces of water are separated by gravity inthe quiet settling section. The treated oil exits the treater through the oil outlet at the top

of the settling section and passes through the oil valve to the storage tank.

Warm vapors from the settling section enter the gas separation section through the

equalizer pipe and mix with the cool inlet wellstream gas. This causes condensation of

valuable heavier fractions in the gas which are recovered in the oil. The gas also passes

through a vaned demister where entrained large liquid droplets are removed and returned

to the oil.

Features

Gas separation section designed to thin film entering emulsion forquick gas breakout.

Immersed downcomer piping from gas separation section to emulsion spreader servesas an effective heat exchanger to preheat incoming emulsion and cool the clean oil.

Deep Freewater Knockout sections below the firebox provides isolation and draw off offree water, thereby avoiding unnecessary heating of water and conserving fuel.

Emulsion spreader rapidly breaks the emulsion and oil into small streamlets for rapidheat transfer by the hot water washing method and assuring minimum fuelconsumption.

Hot water wash heating method reduces foaming tendencies and prolongs firebox life.

High capacity firebox furnishes abundant heat and quick response to thermostatically

controlled demand.

Quick adjustable outside water siphon provides easy interface control over a wide

range of water and oil specific gravities.

Adequate surge volume in the clean oil section relieves heading overload in gasseparation section eliminating the possibility of liquid carryover with the gas.

Cool underside of the diaphragm plate between the gas separation section and thesettling section condenses vapors released in the heating gas that can be recovered

in the stock tank product. Mixing of hot vapors with cool incoming gas in the gasseparation section condenses additional recoverable vapors for additional productvolume and gravity conservation.

The coalescing properties, of a filter section are not required.

Operation

1. The wellstream enters the gas separation section at the top of the treater.

2. Inlet diverter deflects the liquid outward against the treater shell where it spreads to athin film so both free gas and solution gas are released immediately.

3. Oil, water, and emulsion collect on the diaphragm plate and flow through thedowncomer pipe to the spreader underneath the firebox.

4. Free water immediately separates from the oil and is discharged from the treaterbottom section through an adjustable siphon.

5. The oil and emulsion is broken into small streamlets by the perforated tray spreaderand moves up through the hot water section surrounding the firebox. This actionbreaks the large part of the emulsion.

6. The water released settles to the bottom of the treater where it is discharged with thefree water.

7. Final traces of water are settled in the quiet settling section.

8. The treated oil exits the treater through the oil inlet at the top of the settling sectionand passes through the oil valve to the storage tank.

9. Warm vapors from the settling section enter the gas separation section through theequalizer pipe and mix with the cool inlet wellstream gas. This causes condensation ofthe valuable heavier fractions in the gas, which are recovered in the oil.

10. The gas also passes through a vaned demiste
