PROCESS HEATER

 

Electric Process Heaters are typically one pass electric heaters.  Examples of these electric heaters are Fuel Gas Heater, Seal Gas Heater, Nitrogen Heater, Air Heater in Nitrogen Generator, Crude Oil Heater, etc.

 

The process media (liquid or gas) would enter the heater from one end and leaves from the other.  While the media is in the heater, heat would be transferred from the heater element into the media.   Heat transfer includes convective and radiant heat transfer in some application.

 

A few application for process heating

  • Electric Fuel Gas Heater. Most gas turbines requires that the fuel gas to be superheat to a temperature of 50 deg F or more above it dew point. Dew point heater for gas. This is to ensure that the gas does not condensed before it is combust in the gas turbine. The formation condensed gas (usually heavy hydrocarbon) will lead to problems such as deposit on fuel nozzle, damage hot section, and excessive exhaust emission.

  • Electric Seal Gas Heater. Seal gas for use in centrifugal gas compressor requires specific cleanliness and superheating by the manufacturer of seal / gas compressor. This superheating ensures that the seal gas does not condense as it depressurized across the seal surface. The formation of liquid on the seal surface will shorten or damage the compressor seal.

  • Nitrogen Electric Heater - Heating of nitrogen gas in desiccant regeneration.

  • Regeneration heater - Heaters use in regeneration of process including mol sieve.

  • Electric Air Heater - Heating of air in nitrogen generators.

  • Electric Crude Oil Heater in reducing viscosity of crude oil.

Why settle for off-the-shelf heater on your demanding process heating application?  Our process heaters are custom engineered for your particular heating application at no additional cost.  Our design process reviews your specification and would engineer and built a heater, instrumentations and control panels to suit your particular application.  We consider factors such as sheath temperature, maximum vessel temperature, maximum fluid temperature, control philosophy, response time, power controller type, power harmonics, serviceability and much more in the design of the heating system.
