EnvironAir Asia, Inc. (EAI) carry state-of-the-art and cost-effective air pollution control technologies tailor made to suit your requirements. A technology will be recommended, if not yet defined or identified, based on your current industrial processes and practices vis-à-vis costs associated with the equipment to be installed. Flue Gas Desulfurization The best demonstrated available technology for reducing SO2 emissions is Flue Gas Desulfurization (FGD) systems. These systems are designed to introduce an alkaline sorbent consisting of lime or limestone (primarily limestone) in a spray form into the exhaust gas system of a coal-fired boiler. The alkali reacts with the SO2 gas and is collected in a liquid form as calcium sulfite or calcium sulfate slurry. The calcium sulfite or sulfate is allowed to settle out as most of the water is recycled.   Seawater Flue Gas Desulfurization Seawater FGD is a type of wet FGD process. In this process, seawater, which is naturally alkaline since it contains bicarbonates, is sprayed into the desulfurization device to absorb SO2 in the flue gas. The absorbed SO2 is in the form of sulphate ions that are a natural constituent of seawater. The effluent may therefore be discharged into the sea after neutralization.   Fume Scrubbers EAI offers a complete service for the design, manufacture and installation of fume scrubbers to handle corrosive fumes, moist gases and dust laden air flows. EAI employs a high quality team of engineers who have the necessary expertise to handle the design requirements of fume removal systems, and who are specialists in chemical and fan engineering technology.   Thermal Oxidizers Thermal oxidation systems may also be called as fume incinerators, afterburners, or direct flame thermal oxidizers. This is a method of pollution control that can be applied to incineration as a method of pollution control for air polluted with small particles or combustible solids or liquids.   Absorbers The process of absorption conventionally refers to the intimate contacting of a mixture of gases with a liquid so that part of one or more of the constituents of the gas will dissolve in the liquid. Dust Collectors Dust collection is concerned with the removal or collection of solid dispersoids in gases for purposes of: Air Pollution Control Equipment Maintenance Reduction Safety or Health Hazard Elimination Product Quality Improvement Recovery of a Variable Product Powdered Product Collection   Wet Scrubbers When it comes to separating particulate and gases from other gas streams, few techniques are as commonly used as wet scrubbing. Most industrial processes utilize wet scrubbing technology at some point either to recover value components or to prevent harmful compounds from into the atmosphere. Literally hundreds of types of wet scrubbers currently are available. The application of certain basic design parameters varies from vendor to vendor, resulting in similar yet significantly different designs. Some systems are designed for highest removal efficiency, others for ease of maintenance, and still others simply for low cost.   Cyclones Cyclones provide a low cost, low maintenance method of removing larger particulates from gas streams. A cyclone reduces dust loading and removes larger abrasive particles, in this way extending the life of the fabric filter, which is usually used as the final collector.   Filter Bags/Fabric Filters Fabric filters remove dust from a gas stream by passing the stream through a porous fabric. Dust particles from a more or less porous cake on the surface of the fabric. Fabric filter systems are frequently referred to as Bag Houses, since the fabric are usually configured in cylindrical “bags”.   Electrostatic Precipitators An Electrostatic Precipitator (ESP) is particle control devices that use electrical forces to move the particles out of the flowing gas stream and on to collector plates. The particles are given an electric charge by forcing them to pass through a corona, a region in which gaseous ions flow. The electrical field that forces the charged particles to the walls come from electrodes maintained at high voltage in the center of the flow lane.
