Sub-X Thermal Oxiders Brochure

Exclusive Submerged Exhaust (Sub-X®) for Waste Disposal and Product Recovery Selas Fluid's T-Thermal brand of exclusive Sub-X® systems are proven for the safe and economical treatment of gaseous and liquid waste streams. With installed duty ratings from 1 MM Btu/hr (0.3 MW) to 140 MM Btu/hr (42 MW), the Sub-X® is particularly suited for wastes containing organo-metallic compounds, salts, halogens, and aqueous streams. This versatile, integrated waste combustor and quench makes full use of the energy contained in high organic waste streams, as well as destroying highly inert wastes. Organic destruction effi ciencies in excess of 99.99% are proven and guaranteed. Frequently, valuable byproducts can be recovered from the waste streams. Examples include the recovery of concentrated hydrofl uoric and hydrochloric acids, sodium bromide, sodium iodide, catalyst oxides, potassium carbonate, and various salt compounds. With the addition of other unit operations, byproducts such as calcium fl uoride fi lter cake and steam generation have also been produced.Safe Economical Destruction of WastesLiquid & GaseousHigh- and Low-Calorifi cOrganic CompoundsAcidsAlcoholsAminesOrganometallicsMaleic AnhydridesMercaptansNitrogen-boundSulfonatedInorganic (Aqueous) StreamsAlkali SaltsSuspended SolidsHalogenated CompoundsChloridesFluoridesBromidesIodidesMixed HalogensPCBsDi-isocyanatesRecovery SystemsAcidsEnergyMetalsSaltsDioxins and Furans99.9999% Organic DRE••••••••••••••••••••System DescriptionFinely atomized combustible waste is nozzle mixed with combustion air and injected into the Vortex burner. Unlike most conventional burners, the Vortex has the necessary turbulence and swirl action to oxidize the mixture effi ciently.The reaction chamber is usually vertical. When aqueous wastes containing inorganic compounds are present, they are injected below the fl ame zone. Resultant molten salts fl ow down the refractory wall to the quench chamber.1.2.Hot gases pass through a water-cooled downcomer tube and are quenched in the Sub-X® quench tank. The integral tank is a primary scrubber recovering a high percentage of acids and particulates. The tank also acts as a safety device: if quench water supply is lost, the water in the tank will serve as a heat sink until the malfunction is corrected. Additionally, this serves as a seal against natural convection of hot gases throught the APC during an emergency shutdown.Other auxilliaries, including exhaust gas treatment and product recovery equipment, can increase the versatility and profi tability of the Sub-X® system.3.4.Call us today to learn more about our technologies and services, or visit us online at www.selasfl uid.comFive Sentry Parkway East 16225 Park Ten Place, Suite 250Blue Bell, PA 19422 USA Houston, TX 77084(610) 834-0300 Telephone (281) 717-9090 Telephone(610) 834-0473 Facsimile (281) 717-9091 FacsimileSelas Fluid Processing Corporation is a wholly-owned subsidiary of the Linde Group.

Combustible waste is used directly in the burner as fuel. Aqueous wastes are injected downstream of the burner; these contain organic compounds such as alcohols, organic sodium salts, amines, mercaptans and acids, and inorganic compounds such as sodium and potassium salts and suspended solids. Scrubbing produces an inert bleed which complies with the most stringent regulations. This system is representative of over 150 successful Sub-X® installations around the world.Fluorinated WastesBuilding containing a Sub-X® system for the destruction of fl uorinated waste streams at a German chemical plant. Settling and storage tanks are seen in the foreground. The system consists of a down-fi red Vortex burner (inset photo), quench section, absorber, scrubbing towers and a complete liquid treatment system. The intense mixing and short fl ame characteristics of the Vortex burner insure the optimum reaction temperature for the complete destruction of the fl uorinated compounds. Calcium fl uoride fi lter cake is recovered as a usable product and may qualify for resource recovery credit. Mixed HalogensA 5MM Btu/hr Sub-X® system for liquid and gaseous hydrocarbons containing fl uorine and chlorine. Due to the intense mixing of the wastes and combustion air, organic destruction effi ciencies exceeding 99.99% are achieved with less than two seconds of retention time. Downstream treatment is carried out in venturi and packed column scrubbers.Sub-X® AdvantagesRapid quench - cooling occurs in milliseconds, minimizing the reformation of dioxins and furansDirect contact mixing in the quench - maximizes acid absorption and increases effi ciency of particulate removalDeep submergence of the downcomer - an added safety feature that protects downstream equipment from overheating should loss of water fl ow occurIndustries served:ChemicalPetrochemicalPharmaceuticalChemical weapons/munitionsMetals processingSelas Fluid's Technology Center houses pilot plants for research and development on combustion technologies and to provide active demonstrations to validate processes to our clients.•••••
