waste gas cleaning Applications

  • Waste gas treatment for the TFT industry

    Manufacturing TFT/LCD displays requires waste gas treatment as well. Processes that produce large scale Thinfilm Transistors (TFT) on glass substrates, for instance, use Chemical Vapour Deposition – CVD – to separate the thin films onto the material. The process requires cleaning the process chamber periodically and usually employs etching with NF3. Etching of the separated thin films typically utilises CF4, SF6 and chlorinated gases, which release large amounts of waste gas mixtures.

SIES design & Supply Mobile Flare for Oil and Gas industry, Waste gases, LFG operations and tank Cleaning operations. The Flares have inbuilt capabilities to handle wide variety of gas with full safety and precaution as per API Standards..

  • Biogas recovery for waste to energy industries

    HydroThane BSP technology is the best method for H2S removal combining deep H2S removal, a very high reliability and availability, and low lifecycle costs. The clean biogas can be used to produce electricity or to replace natural gas in a boiler.

    Waste recovery for glass manufacturing

    Tetronics` twin torch system has been used continuously for the commercial production of high quality silica glass for optical applications since 1992. Tetronics’ unique twin torch technology allows a plasma arc to be created in space, which enables a falling stream of high quality silica powder to be melted at the junction of the two arcs to form an ingot of high optical quality silica glass. By using plasma as a clean and controllable heat source, the product has a high degree of integrity, because the absence of a natural gas flame means the resulting product is free from bubbles, contamination and other defects.

  • Biogas to Elecricity

    The range of supply of biogas to electricity solutions is from 10 kW to 1 MW. All the components of the solution are provided with matching capacities. It comprises the biogas digester system of the desired capacity, gas storage, biogas cleaning system to get rid of H2S from the gas, and the biogas genset. In the digester system, one may have a pre-digester or a feed mixing chamber or both. On the post-digester side, liquid from the slurry is separated and is recycled for feed preparation. It reduces the overall fresh water demand of the scheme. The digester itself may be temperature controlled and the input for the same could be given from heat recovery of the genset or from a solar heating system or from any other heat source as the case may be.

  • Biogas for Cooking

    This solution comprises a Biogas Digester of desired capacity working with specific substrate as input. It may or may not have H2S scrubbing system, depending on the quantity of H2S in the biogas and the requirement by the customer for cleaning it. As the heating value of biogas is almost half that of cooking LPG, specially designed biogas burners are provided to improve cooking speed. Depending on the demand by the customer, a blower to increase gas pressure may be employed.

  • Energy and Fuels from Municipal Solid Waste (MSW)

    Municipal Solid Waste (MSW), which includes household waste, is the residual waste put into a black bin bag or wheelie bin. MSW contains a mixture of recyclable, organic, inorganic and biodegradable materials. We recover as many recyclable materials as possible before drying and shredding the remainder to make a Refuse Derived Fuel (RDF) for the process. Our energy from waste process, Gasplasma®, transforms the RDF into a clean hydrogen-rich synthesis gas (syngas).

  • Gas infusion technology solutions for the water treatment industry

    Every municipality in the developed world has some form of water and wastewater treatment system. This varies from simple outfalls direct to the ocean to very sophisticated activated sludge plants with multiple unit processes dedicated to converting human waste, industrial effluents and storm runoff into clean water discharges and solids acceptable for some form of reuse. inVentures using its gas inFusion technology, has developed the gPRO system for the prevention and remediation of major algae blooms that negatively affect the water quality for millions of people. The company is currently working with several major water authorities on algae prevention programs by efficiently oxygenating specific regions of the water storage areas. Target Oxygenation prevents the build up of algal masses. Algal masses often require expensive treatment remedies and cause major taste and odor issues within drinking water supplies.

    Industrial air pollution control for the electronics and electrical industry

    The world`s appetite for electronic devices - from simple household appliances to sophisticated computers - has led to rapid growth of both these industries. Typically for the electronics industry, there are large waste gas streams (up to 400,000 Nm³/h) with relatively low concentrations of different solvents. The waste gases mainly occur in coating, cleaning and etching processes during the production of semiconductors, CDs/DVDs, Blue-ray discs, DVTs, TFT-LCD and plasma displays. The electronics industry has important standards to meet regarding environmental protection. CTP complies with these requirements: From zero emission goals, to installations on the roofs of production facilities.
