Gas Gathering Systems and Oil Production Facilities by EN-FAB Inc
EN-FAB Inc delivers gas gathering systems and oil production facilities with expert design, fabrication, and installation to improve efficiency, reliability, and field performance. Engineering design and fabrication of equipment for onshore and offshore production facilities has been the mainstay of EN-FAB’s business. EN-FAB personnel are particularly adept in design, engineering, and construction of production equipment such as; 2 & 3 phase separators, heater-treaters, desalters, demulsifiers, glycol dehydration units, fuel gas skids, vapor recovery units, etc. Qualified service technicians are available for start-up service and commissioning. This combination of unique abilities has enabled EN-FAB, Inc. to be a leader in supplying Early Production Facilities and Systems.
An early production facility is a complete facility to produce oil and gas and dispose the produced water. This facility is usually located on land, but barge facilities are also common. The size range is usually between 5,000 to 60,000 barrels per day. All the equipment for treating the oil, gas, and water such as separators, heaters, scrubbers, power supplies, lighting, water treatment, etc. is provided as a package. The facility is usually all skid-mounted and is put in place, interconnected, and commissioned by EN-FAB, Inc. Early production facilities are becoming very important to the oil companies due to the necessity to get a field or some part of the field on line and producing in a minimum amount of time. EN-FAB can provide a complete production facility in short time, including all the equipment to treat the oil, gas, and water, plus the equipment for power generation, lighting, control rooms and site design.

Indirect fired bath Heaters - also known as “line heaters” have a long history of successful applications in gas plants, pipelines, power plants and other applications. Typical services for EN-FAB indirect heaters include:
- Natural Gas Heating
- Gas Vaporization
- Crude Oil Heating
- In Line Liquid/Gas Heating
- Condensate stabilizing
- Fuel Gas Heating
Indirect heaters works by submersing a fluid or gas carrying process coil into a heated bath solution, which indirectly heats the coil allowing for safe, efficient, uniform heating of oil and other fluids. Common bath mediums include water, water/glycol and hot oil.
Gas Fired Salt Bath Heaters
Salt melts can be used to meet the higher operating temperature requirements of more specialized applications.

Horizontal heater treaters are used in the oil/gas industry to help facilitate oil/water separation by speeding up emulsions separation through applying heat. Heater treaters can be thought of as low pressure, three phase separators equipped with fire tubes. They separate gas from the incoming emulsion and separate the emulsion into a water phase and an oil phase. Heater treaters can also function as a free water knockout, a heat exchanger, a filter, and as a water wash tank.
Heater Treater Applications
The heater treater is normally found downstream of a two-phase separator on a high pressure system. It can be found downstream of the well, a free-water knockout or gun barrel on a low pressure system. Heater treaters are used where the emulsion cannot be broken using just retention, quiescence and chemical demulsifiers. The addition of heat is required to break the emulsion. Heat lowers the viscosity of the oil making it easier for the water to settle. It also creates molecular movement which aids in the coalescing of the water droplets.
