It is usually desirable to separate liquids from gas in produced well streams for better pipeline efficiency and economics. The separation of the gas, hydrocarbon liquid, and water into separate phases is accomplished by reducing the velocity of the fluid flow by passing it through a separator. Within the separator vessel enough time is allowed for the fluid components to separate by the forces of gravity.

Vertical and Horizontal Downflow Treaters
Electrostatic Treaters and De-salters
Vertical Cold Weather Treaters
Steam Treaters
Oil Stabilizers
An oil-water emulsion consists of a suspension of small droplets that will not separate into two distinct phases by gravity separation alone. One economical method of breaking an emulsion is by using a heater-treater to add heat to the fluid along with settling or retention time to aid in the separation process. Heating an emulsion will change the properties of the components and allow separation of the phases to take effect and produce a pipeline quality oil.
Treaters
Heaters
Indirect Water Bath Heaters
Direct Heater
Steam Generators
It is usually necessary to heat natural gas streams, prior to reducing the well head pressure to pipeline pressure, in order to prevent hydrate formation and plugging at the pressure reducing valve or choke. The most practical and economical method for accomplishing this is by the use of an indirect water bath heater. Indirect heaters are also used to reheat gas streams when the gas must travel great distances down pipelines. The gas can be cooled by the ground, and this will cause the temperature of the gas to drop below the hydrate formation temperature at the line pressure. For most natural gas streams, the hydrate temperature is above 32°F.
Freewater Knockouts
Horizontal and Vertical
Heated Freewater Knockouts
Flow Splitters
Freewater knockouts are normally large open vessels which operate under pressure for the free gravity separation of oil and water streams. They are often used upstream of either vertical or horizontal treaters to separate and remove free water from the oil-water emulsion so the energy is not wasted in heating the free water within a fired treating vessel.
Gas Production Units
Heater-Separator Units
Single-well Packages
Multi-well Packages
Horizontal or Vertical Arrangements
A gas production unit is an enclosed skid package consisting of an indirect water bath heater and a high pressure separator, including interconnecting piping and instrumentation. It is a compact piece of primary production equipment ideally suited for a high pressure gas-condensate well. The separator and indirect heater components are designed and sized using the same criteria and approach as the stand-alone vessels.
