New Equipment

GST is able to design, engineer, fabricate, and install the majority of combustion heat transfer equipment utilized by the refinery and petro-chemical industry. With strong expertise in manufacturing and construction, optimized fabrication techniques are applied that result in minimal field installation cost and schedule. In addition, extensive performance studies have paved the way for innovative and unmatched process design techniques and solutions.

Revamps

The custom nature of direct fired heaters makes each unit not only unique on how it operates, but also how it is manufactured. When attempting to modify the unit to enhance or expand its performance, taking a “standard” design approach can be problematic. With extensive real-life / hands-on experience, GST understands the challenges and potential benefits associated with revamping existing equipment. Also, through the collaboration of InServ’s construction and fabrications services, project development and planning is optimized to ensure turnaround cost and duration is minimized. The ability to execute a project to the highest level is unsurpassed in the industry.

Field Studies

The ability to truly understand how custom design equipment performs can only be achieved through comprehensive heater studies that incorporate “real” operating characteristics identified through field testing This service extends well beyond simply obtaining board data. A GST thorough field data gathering and analysis confidently identify actual conditions of any manufacture’s equipment that are carried to future performance predictions. Through countless heater evaluations, GST has developed proprietary software that allows the ability to incorporate state-of-the-art engineered solutions to all process heaters including black oil services such as Crude, Vacuum, Cokers, and Visbreakers.

Emergency Response

The collaboration of GST and other InServ companies affords the competence to thoroughly and expeditiously get a fired heater back into good working order. The ability to orchestrate all the needed disciplines required to inspect, plan, and execute an emergency response project under one roof is unmatched. For a piece of equipment that is generally the heart of the unit, every hour can be costly when experiencing an unplanned shutdown caused by fire or internal damage. GST can minimize coordination headaches and limit downtime through its integration capability.

Computation Fluid Dynamic Modeling (CFD)

Whether for new designs or revamps, we can use CFD modeling to evaluate custom solutions to determine the best strategies for your unique service conditions and minimize the risks of applying innovative design concepts. For heater diagnostics and revamps, we can visualize equipment operation to reveal the driving forces behind heater behavior. Insights gained from CFD models ensure that we are attacking the cause of the behavior and not just the symptoms. With our combination of in-house experience and CFD modeling, we are able to simulate practically any fired heater configuration of burners, process tubes, and auxiliary equipment to evaluate many important heater characteristics.
