Cimarron Energy - Oklahoma City, OK | Line heaterCimarron designs and manufactures indirect water bath heaters and line heaters to heat gases or liquids safely in a variety of sizes and with a number of customer preferred options.  Applications include:

  • Heating natural gas prior to separation and pressure reduction
  • Prevention of hydrates before pressure reduction at distribution city gates
  • Heating of gas during transmission stages
  • Controlling separation temperatures of gas and liquids to increase the efficiency of separation and prevention of hydrates
  • Heating of water for water jacket applications
  • Heating of heavier crude oils for easier processing and fluid movement

The principal benefit of indirect heating is that the combustible fluids are heated in a non-combustible fluid and separate from the firetube, in many cases a glycol/water mixture.  The fluids are contained in a designed coil bundle comprised of multiple passes and paths and have no direct contact with the heat media that provides the necessary heat transfer area to meet the specific conditions required.  Both heat transfer area and mixture velocities, which vary depending on the composition, pressure and temperature conditions, are key factors in the design of the coil bundle.  The heat supplied by the firetube to the heat media is modulated by temperature measurement in the product stream to ensure that the customer specifications are achieved.

Cimarron regularly manufactures heaters ranging from 100,000 to 4 million Btu per hour.  Our custom engineered designs allow for a number of options to meet the varying requirements of our customers.
