Air Pollution Treatment Applications

Premium

Wastewater Treatment

Many industrial and pharmaceutical processes generate wastewater with volatile contaminants that increase the COD and BOD to a point where discharging to municipal wastewater is very costly or not an option. These contaminants can be removed from the water by distillation, substantially lowering the disposal cost, and, in many cases, the removed components can be further purified and reused in the process. MEGTEC offers the following solutions to remove the volatile contaminants and make wastewater suitable for discharge to most municipal wastewater treatment plants: Stripping columns using direct steam or a reboiler Distillation columns using indirect steam heat sources Our technologies have been applied to a range of processes including wastewater treatment from industries such as Pharmaceutical, Semiconductor, Chemical and Petrochemical.

Cement

MEGTEC's extensive scrubber experience applies to the cement manufacturing process for the effective control of SO2 and HCl by the injection of lime slurry. Our customers can achieve up to 90% reduction of SO2 and 98% reduction of HCl using microfine or standard lime. The TurboSorb Spray Dryer Absorber (SDA) can often retrofit into an existing gas conditioning tower, or downcomer duct, to avoid the high cost of new capital equipment.

Ethanol and Biofuels

Controlling the VOCs and CO emissions produced in the feed dryers (wet and dry milling), coupled with the particulate matter being introduced and the need for the reduction of NOx are just the start of having a successful abatement solution. The challenges of smooth pressure control that reduces dryer fluctuations and plug resistant media that lessen the frequency of bake-outs are also part of a successful abatement system and we have the solutions. Our engineered oxidation systems provide reliable performance with minimal maintenance requirements. Externally accessible valve bearings and other critical components are kept out of the corrosive moisture-laden streams extending the life of the equipment and facilitate maintenance intervals. Our simple oxidizer designs control your emissions with minimal facility intervention and allow us to provide you with reliable and dependable equipment.

Iron and Steel

SoniCool™ Evaporative Gas Cooling & Conditioning uses a finely atomized water spray to cool EAF, BOF off-gases from over 2,400°F (1,315°C) to as low as 240°F (115°C), protecting ductwork and downstream air pollution control equipment from high temperature and sparks, while providing rapid cooling for dioxin and furan control. By optimizing humidity levels, SoniCool™ helps electrostatic precipitators. The water spray completely evaporates while cooling gases. There is no free water and no troublesome deposits in ducts, towers or hoppers. Turbotak rugged nozzles are made to the exact requirement, and ideally suited to the harsh conditions in the steel manufacturing process while still producing ultra-fine sprays, with precise control of dropsize and spray coverage.

Petrochemical

Durable regenerative thermal oxidizer (RTO) technology is at the core of our systems. MEGTEC designs and engineers system solutions to meet your special requirements, ranging from energy-efficient treatment of dilute volatile organic compound (VOC) flows, such as tank ventilation, to demanding applications utilizing VOC energy for secondary heat recovery; for example, in the form of process streams. This can include pre- and tail gas treatment systems, and could handle hazardous components such as sulphurous or chlorinated hydrocarbons. For special requirements, we can offer FTO (flameless thermal oxidation) and we can design systems operating safely on oxygen contents below 5%.

Coating and Laminating

MEGTEC’s experience and application know-how are at your command for tough drying and web handling applications such as slow-drying coatings and materials or thin film coating and laminating. Dryers can be equipped with a wide variety of nozzle configurations ranging from simple slot nozzles to sophisticated Coanda-style air bars and patented air foil systems. A full range of heat sources are available including steam, direct and indirect gas-fired, thermal oil, electric, hot water and IR. In addition, the air handling systems can be integrated into the dryer enclosure or stand-alone for remote installation. When the process requires pollution control systems for solvent-based applications, MEGTEC also offers regenerative thermal oxidizers, solvent recovery, distillation and purification systems. MEGTEC also offers waste heat recovery packages to “close the energy loop” between pollution controls and the process, in order to reduce production costs and increase customer profits

Gas detection analyzers for pollution control

Government and environmental groups are forcing industries with medium to high VOC exhausts to reduce emissions by as much as 98%. Incineration using pollution control devices such as oxidizers and flare stacks is one way to bring the exhaust emissions in line with the regulations. Capturing and reusing solvent in a solvent recovery system is another way.
