Revolutionary Natural Gas Line Heaters Cut Fuel Costs 50%, Reduce Maintenance

Revolutionary Natural Gas Line Heaters Cut Fuel Costs 50%, Reduce Maintenance

Successful Practice Challenge:

Anytime gas pressure is reduced downstream of the regulator, ice can form.  This is called the Joule-Thomson or Joule-Kelvin effect and is the basis of how modern refrigeration techniques work.  A pipeline heater system is needed to keep the gas flowing safely.  Until now, such heaters can be expensive to operate and tend to require significant maintenance.

Successful Practice Solution:

Cold Weather Technologies (CWT), a product line of Grit Industries Inc., now offers a revolutionary line of Natural Gas Line Heaters that are less expensive to operate and maintain in upstream, transportation, and distribution systems.

Instead of a conventional bath heater, these units are true constant temperature heaters. Like a typical home furnace, the CWT heat can be set to a certain temperature, and then relied up on to maintain that temperature.

There are a wide range of sizes to choose from, and each heater is made to work specifically for a customer’s application. The system can be retrofitted to install and replace the existing fire tube systems in the industry.

Here are some of the units’ advantages:

  • Increased heat transfer efficiency which reduces fuel consumption 50% or more
  • Increased safety over conventional (no need to top up)
  • Reduced environmental risk and emissions
  • Increased thermal efficiencies – in the order of 70 to 80%
  • Ease of operation and dependability
  • Reduced maintenance
  • Safe to light and silent
  • A fraction of the glycol requirements over conventional units
  • No requirement for secondary containment (check with local authority)
  • No outside power required

Here is an example of fuel savings:

A 500,000 btu/hr CWT heater will do the work of 1.0 mmbtu/hr conventional heater.  If we assume that both are running 50% of the time, the conventional heater would consume 2,190 mmbtu/year more than the CWT. Using a gas price of $7.00 per mmbtu, the extra fuel cost is in the order of $15,330 annually.

Grit is especially proud of the efficiencies that these heaters are capable of, not just because of the massive energy savings, but also the tremendous reduction in greenhouse gas emissions.  The heaters do not need costly, and environmentally-hazardous glycol either.
