Oil treatment system Heater – Treater


Oil treatment system Heater-Treater replaces several installations at once. By using this system, all components of a mixture can be treated at the same time. Heater-Treater is an oil, gas and water separator equipped with direct heating system. Heater-Treater is used for obtaining pure oil from oil well production and preliminary dehydration. The system is capable to operate in harsh climatic conditions with temperature reaching -60oC. In addition to that, the system can endure strong winds and therefore can be installed in open areas. Heater-Treater unit is almost ready to operate at its delivery which contributes to a significant decrease of time and money spent on the construction and installation work.

Heater-Treater benefits:

  • One system is used while solving multiple tasks at once
  • It is possible to separate oil of any volume regardless of its pressure
  • Gas separation occurs along with the existing pressure of the incoming oil
  • "Maloney" filters provide improved purification (the concentration of water in oil does not exceed 5 per cent)
  • Increased fire safety is ensured by a unique heating section design
  • The system automatically performs safety control

Heater-Treater system and its operating principle

The liquid and gas enter the Heater-Treater through an inlet on the top of the tank. At the inlet, gas and liquid are separated. The separated gas rises up to a moisture extractor and then enters the gas outlet pipe. In the moisture extractor, the liquid gets coagulated from the gas and then mixes with the liquid phase at the bottom of the tank. The gas moves forward into the valve-controller responsible for the pressure and the level of oil in Heater-Treater.

The liquid gets on to the front side where the flow is separated. From there, it moves down to the bottom of the tank under the heating pipes. During this process, the spare water is separated.

The temperature in the heating pipes and furnace is maintained by processing the petroleum gas coming from the fuel preparation unit. The control panel is equipped with temperature and flame control devices.

A more resistant emulsion is heated by the heating tubes. Coalesced water droplets flow down to the lower part of the tank and get mixed with the remaining free water. Whereas oil droplets flow together and float up to the coalescing filters (coalessors).

Oil product filters, coalessors, consist of profiled polypropylene plates placed one above the other. Oil drops rise up to the top layer of the filter forming a membrane. Corrugated plates placed above each other create a large coagulation area. Here, droplets form large globules together and squeeze the water out. The water by the means of gravity force flows down to the lower part of the tank until reaching the water discharge pipes. The dehydrated oil rises up to the oil phase, then moves into the collector. From there, absolutely purified oil discharges the unit through a pipe.
