History

Thu, 27 May 2010 17:46:46 GMT

Headquartered in Houston, Texas, GTC Technology US, LLC (GTC) is a global licensor of process technologies, offering engineering services, process equipment solutions, chemicals and catalysts to the petrochemical, refining and gas processing markets. Our heritage of innovation expands more than a decade, dating back to 1994 as a process technology solutions division of Glitsch Inc., a mass transfer equipment company owned by Foster Wheeler Corporation. In 2002, GTC was taken private in a 50-50 joint venture between the GS Group and our management team, who recognized the need for an independent technology licensor in the chemical process industry. Over the next seven years, GTC experienced unprecedented growth, celebrating dozens of successful licenses while gaining quick recognition in the aromatics and refining fields. In 2009, GTC announced a change in ownership structure, selling individual minority interest in the company to SCG Chemicals and Süd-Chemie AG. The...

Heater Cleaning Technology

Thu, 27 May 2010 17:46:16 GMT

GTC can help clients eliminate slag buildup and other fire side fouling and extend time between major fired heater/boiler maintenance jobs with our advanced fired heater/boiler chemical cleaning technology. Our technology can improve heater efficiency without shutting down plant operations in a range of applications including refinery heaters, petrochemical fired heaters and oil-fired boilers.

Our fired heater/boiler chemical cleaning technology can be used to clean air preheaters (APH) by spraying our proprietary liquid chemical through specially designed nozzles, indirectly onto the radiant and convection tubes of the fired heater. The chemical vaporizes and covers the targeted exposed tube surfaces in a similar manner as the firebox chemicals. This process can also be completed without an APH bypass.

Our fired heater cleaning process has been proven to significantly increase feed throughput, lower fuel costs and reduce greenhouse gas emissions all without plant facility modifications. Our experienced staff can deliver online fired heater cleaning services in 2 -5 days depending on heater geometry, layout, operations and conditions. Please contact us to learn more about our advanced fired heater technology.
