Sour Water Stripper GT-SWS

Thu, 22 Dec 2011 22:36:36 GMT

GT-SWS™ is a process designed to remove H2S and NH3 from sour water. Sour water can be generated in a variety of ways in a refinery and a petrochemical plant. Effectively and robustly stripping H2S and NH3 either together or separately is an essential operation. Innovations in mass transfer and contaminant control improve overall energy efficiency. Process Description The sour water is generally fed to a sour water storage tank to help separate hydrocarbons and enable feed mixing to stabilize the feed composition to the stripper unit. Sour water from tankage is heated by hot stripped sour water and fed to the sour water stripper. Heat is added to the stripper either directly (live steam) or through a steam driven reboiler. H2S and NH3 rise to the top of the stripper column where they are removed. Stripped sour water leaves as the tower bottoms and suitable for reuse in the plant, or sent for further waste water processing. In the case of systems where the H2S and NH3...

GT-MeriSorb Acid Gas Removal and Acid Gas Enrichment

Thu, 22 Dec 2011 22:34:51 GMT

GT-MeriSorb is a solvent based technology to capture acid gases by absorption followed by regeneration. Optimized solvent chemistry is critical to manage amine degradation and operation in the presence of heavy hydrocarbons, heat stable salts, and oxygen. Innovations in mass and heat transfer improve overall energy efficiency. Process Description Gas containing H2S and CO2 is contacted in an absorption tower with a solvent which has a preferential affinity for the acid gas. This allows the feed gas to be stripped out of these components which end up in the solvent. The purified gas leaves at the top of the absorber tower. The rich solvent is then heated through the lean-rich exchanger, and sent to the stripper column where it is thermally stripped. The lean solvent is re-circulated, cooled through the lean rich exchanger and then through fin-fan or other coolers prior to entering the amine absorber. For acid gas enrichment, the solvent is chosen to have a preference for...

Sulfur Recovery - GT-Claus Modified Claus Sulfur Recovery

Thu, 22 Dec 2011 22:28:59 GMT

GT-Claus™ is a modified Claus technology. GTC Technology, in alliance with Rameshni and Associates (RATE) and Shandong Sunway, is able to offer highly customized solutions for sulfur recovery across a range of industries and streams recovering sulfur in the 3 - 2,500 Ton/day range. Process Description The GT-Claus™ modified Claus process has a thermal (combustion) section that partially converts H2S to SO2, followed by combustion and catalytic sections that react the H2S and SO2 to recover sulfur. The gas exits the thermal section, enters a waste heat boiler where heat is recovered. Sulfur is then condensed and the unreacted gases are reheated before introduction to a Claus catalyst bed. Following the catalyst bed, the sulfur is again condensed out before repeating the reheat, catalyst bed stages again. Overall sulfur recovery depends on the number of stages, and can reach 98%. GTC can customize the configuration fo the GT-Claus unit depending on the acid gas...

Hydrogen Sulfide Removal Technology - CrystaSulf

Thu, 22 Dec 2011 22:17:22 GMT

GTC Technology, in alliance with CrystaTech, is supporting projects utilizing CrystaSulf technology, a nonaqueous process that has been developed specifically for the treatment of high-pressure sour natural gas in medium-sized sulfur applications with produced sulfur in the range of 0.1 to 30 tons per day. Process Description CrystaSulf uses a nonaqueous solution with a high solubility for elemental sulfur. Because the elemental sulfur stays dissolved in the solution, there are no solids in the liquid circulated to the absorber. By design, CrystaSulf avoids the problems that make the aqueous sulfur recovery systems unsuitable for direct treatment of high-pressure sour gas. With this process, H2S is removed from the sour gas in a conventional tray absorber. The H2S reacts with dissolved sulfur dioxide (SO2) to produce dissolved elemental sulfur. There are no solids in the absorber, flash tank, or solution lines, which minimizes the chance of plugging. Rich...

Sulfur Recovery - GT-DOS Direct Oxidation to Sulfur

Thu, 22 Dec 2011 22:15:28 GMT

GT-DOS™ is a patented technology developed by TDA Research and licensed worldwide by GTC Technology. GT-DOS™ offers simplicity of operation, and is specifically applicable to lean acid gas streams, cost effectively recovering sulfur in the 0.1 to 200 Ton/day range. Process Description The GT-DOS™ technology converts H2S catalytically directly into sulfur, from lean (low concentration) H2S streams. The sulfur conversion efficiency is around 90% in a single pass. H2S + ½ O2 -> S + H2O The H2S containing feed stream is mixed with air and heated to the reaction temperature and fed to the GT-DOS™ reactor. The mixed metal oxide catalyst has been proven to be resistant to high concentrations of hydrocarbons, including aromatics and olefins. The reacted stream containing sulfur vapor is condensed to recover the sulfur. The gas stream can be further desulfurized with sorbents or tail gas treatment. Heat integration between 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.
