- VOC / RTO Abatement Systems
VOC / RTO Abatement Systems
Regenerative thermal oxidizers (RTOs) and other types of thermal oxidation systems have proven to be an effective and energy-efficient method of abating volatile organic compounds (VOCs) and other pollutants emitted by industrial plants. However, particulate matter in the emission stream can be a particularly difficult problem which can contaminate the surrounding absorbents. Therefore, particular attention should be given to selecting the configuration and material comprising heat exchange media to mitigate potential problems with particulate matter and to ensure reliable, economical and safe operation of thermal oxidation systems.

- ASH Systems
Many industrial processes consume large volumes of specially conditioned air. Attention to proper air replacement is therefore vital to the manufacturing process, other equipment, and worker health. Design Systems, Inc. has a long history of engineering a complete range of air replacement systems from simple air make-up units to large air supply houses. These systems can be equipped with high efficiency filtration and full control of humidity, air temperature, and particulate filtration, among many other criteria.
Design Systems, Inc. is experienced in developing control systems that allow the air replacement system to react to changing outside air conditions without operator intervention. Air supply houses can be equipped with water chillers and hot water heating systems. Humidification can be supplied via evaporative media pads, sprayed coils, steam injection or high pressure water spray. Our engineers have helped install air houses on recirculated paint booths, which can save many thousands of dollars in operation costs.
- RTO Systems
A Regenerative Thermal Oxidizer burns extremely lean waste gases without consuming much fuel, and operating at a temperature roughly the same as a normal thermal oxidizer, but the hot flue gas passes through a heat exchange module before reaching the stack.
Design Systems, Inc. has managed builds and reworks of RTO systems small and large, working with the customer to get the most efficiency out of your existing or new abatement process. We possess the expertise to take any size system from concept to commission, managing the complete project from start to finish while ensuring compliance with government regulations and your spec.
- Wet Scrubber Systems
Wet Scrubber Systems
The term "wet scrubber" describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid through a variety of means including spraying it with the liquid, forcing it through a pool of liquid, or through other contact methods, in order to remove the pollutants.
The design of wet scrubbers or any air pollution control device depends on the industrial process conditions and the nature of the air pollutants involved. Inlet gas characteristics and dust properties (if particles are present) are of primary importance. Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. The versatility of wet scrubbers allows them to be built in numerous configurations, all designed to provide good contact between the liquid and polluted gas stream.
Some advantages of a wet scrubbing system include:
- Wet scrubbers can tolerate high temperatures and moisture.
- Flue gases are cooled in wet scrubbers, which results in smaller overall equipment size.
- Wet scrubbers can remove both gases and particulate matter.
Some possible pitfalls of employing a wet scrubber system include:
- Wet scrubbers can neutralize corrosive gases.
- Potential for corrosion.
- Entrainment separation or mist removal is required to obtain high efficiencies.
- Treatment or reuse of spent liquid required.

- Paint Scrubbing Systems
Paint Scrubbing Systems
Paint spray booths generally employ a discrete pod gas scrubber system for removing contaminants from the air of a work area. Each scrubber pod includes an inlet section having opposed converging planar walls and side walls, an intermediate section having opposed diverging walls and side walls communicating with the inlet section through a reduced diameter venturi, and an outlet section having a bottom wall perpendicular to the longitudinal axis of the scrubber pod, a diverging top wall and an end wall. The end wall includes an orifice opening and orifice plates for adjusting the orifice opening and the combined lengths of the aligned scrubber pods are between fifty and ninety percent of the total length of the scrubber system, more preferably between sixty percent and eighty five percent of the total length. This type of scrubber system significantly reduces the noise generated in the work area located above the gas scrubber system.
Design Systems, Inc.'s has done many paint scrubbing system jobs for customers such as large automotive companies, aircraft, and other transportation industries.
- Air Balancing
Air quality is of paramount importance to your workplace, both for preserving the quality of the products your facility may produce and for protecting the well-being of your employees. General methods for improving the indoor air quality in buildings include source control, ventilation, air cleaning, and others. In cases where the contaminant cannot feasibly be removed, source control is the only option. Otherwise depending upon the contaminant, air cleaning, ventilation, or a combination of the two and others may be employed. The factory floor may produce or host a laundry list of byproducts such as:
- Carbon Dioxide
- Carbon Monoxide
- Particulate Matter
- Bio Aerosols
- Byproducts of Combustion
Allow us to conduct a ventilation study to see if these or other contaminants are present in your system and if they are being adequately mitigated. Design Systems, Inc. will then customize a plan for moving forward outlining what steps should be taken for the end result of a clean, balanced air system.
- Scrubber Systems
A dry or semi-dry scrubbing system, unlike the wet scrubber, does not saturate the flue gas stream that is being treated with moisture. In some cases no moisture is added, while in others only the amount of moisture that can be evaporated in the flue gas without condensing is added. Therefore, dry scrubbers generally do not have a stack steam plume or wastewater handling/disposal requirements. Dry scrubbing systems are used to remove acid gases (such as SO2 and HCl) primarily from combustion sources.
Dry scrubbing systems can be categorized as dry sorbent injectors (DSIs) or as spray dryer absorbers (SDAs). Spray dryer absorbers are also called semi-dry scrubbers or spray dryers.
Design Systems, Inc. has engineers experienced with all varieties of non-wet scrubbing systems. Our staff has worked countless installations and designed solutions to meet the needs and budgets of a wide range of industries and projects. Talk to us today about your next project!
