Indirect Line Heaters
Line heaters are used to heat natural gas prior to transmission in the pipeline to prevent hazardous hydrate blockages and freezing off of downstream equipment. Line heaters are typically installed at gas well sites where the high wellhead pressure must be reduced, along gas gathering pipelines that join remote fields to processing plants and at city gate stations where local distribution companies purchase, meter, regulate and odorize processed natural gas.
KOCKEN Sistemas de Energia Inc. Indirect Fired Heaters are of rugged oilfield construction and high combustion efficiency. The heavy gauge heater shell is equipped with one or more firetubes providing combustion heat to a bath which in turn transfers heat into preheat / reheat process coil(s), heating natural gas, condensate and / or oil to the respective required outlet temperature. The fluid of combustion is generally process natural gas; however, ethane, propane or light oils are also viable options. All KOCKEN Indirect Fired Heaters are supplied with a Bath Saver of sufficient capacity to contain the expansion of the bath medium from ambient to operating temperature and to reduce vaporization losses.
All KOCKEN Indirect Fired Heaters are constructed according to the API 12 K Specification for Indirect Type Oil-Fired Heaters, GPSA Section 8, CSA B149.3, and applicable Industry Codes and Standards.
