Specializing in custom designed high efficiency combustion (HEC) technology for sulfur recovery units (SRU) since 1993. Applications occur in principally three primary areas; reaction furnace burners, reheater / RGG  / SuperclausTM / SCOT burners, as well as tail gas incineration systems.

HEC’s experience encompasses decades of in-house CFD studies and assessments, aided by an accumulation of empirical field data from operational units. CFD is used to research and continually evolve burner designs as well as trouble shooting or conduct root cause analysis for existing plant improvements and operational issues.

Reduced long term maintenance, reduced downtime and foremost, reliability are primary concerns for basically all SRU facilities globally. HEC strives to excel with our work and refinements in this area which are equally beneficial to new and existing (retrofit) applications.

HEC SRU installations range from the smallest up to the largest tonnage refinery and gas plants in the world. These comprise basic air only operation and progressive enrichment up to 100% oxygen substitution. HEC contends with extremely lean feeds to refinery grade acid gas processing and in some cases substantial levels of contaminants (hydrocarbons, NH3 and BTX).
