Pollution Control Icon

CleanCap provides environmental abatement technologies worldwide including air pollution control, water treatment, and integrated energy recovery systems. Through many years of experience, we continue to lead with our products in many worldwide production industries while providing customer focused aftermarket services to maintain plant operations in compliance with regulations and advance value-added carbon reduction strategies.

Air Abatement Environmental Technologies

Air pollution control solutions cover a wide range of products. Our expertise and partnerships align with thermal and catalytic abatement technologies, wet scrubbing, and particulate filtration.

We can remove:

  • Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs)
  • Nitrogen Oxides (NOx)
  • Dioxins & Furans
  • Acid Gases such as Sulfur Oxides (SOx), Hydrochloric Acid (HCl), and Hydrofluoric Acid (HF)
  • Particulate matter such as PM2.5 and PM10
  • Mercury (Hg) & Heavy Metals

Thermal and Catalytic Abatement

Thermal oxidizers come in the simplest form with the ability to treat waste gases in lower volumes and higher organic concentrations. The complexity increases, but with many advantages, when internal heat recovery is incorporated in Thermal Recuperative Oxidizers and Regenerative Thermal Oxidizers (RTOs). Any of the thermal units can be provided in Catalytic form with the addition of base or precious metal catalyst which effectively lowers the temperature at which the hydrocarbon bonds break apart to create water vapor (H2O), carbon dioxide (CO2), and heat energy.

A version of thermal abatement often deployed by CleanCap is in the form of a Vapor Combustor Unit (VCU), also known as an Enclosed Flare. In this technology, waste gases are introduced into the device as an inert gas mixture prior to being mixed with enough oxygen for proper combustion. The reaction is not visible. However, Flares provided by CleanCap do have a visible flame as the inert gas exits the top of the stack and uses ambient air oxygen to achieve partial combustion.

NOx Control Strategies

Four strategies used in combination to control NOx

Wet Scrubbing

Wet scrubbers use a liquid solution to chemically absorb polluted gas chemicals through mass transfer. These systems come in many different designs depending on the application, available space, and the complexity of chemicals required to be abated.

Through the deployment of our thermal and scrubber technologies, we are able to reduce and limit nitric oxide and/or nitrogen dioxide (NOx) emissions with pretreatment, combustion control, post-treatment, and process modifications.

Particulate Filtration

Our filtration technologies center around particulate matter (PM) removal. From cyclones, flat media filters, to dust collectors and ceramic filters, CleanCap provides a type of filtration package for almost every industry. Many of the filters we use are placed in line with our other equipment to minimize maintenance and maximize uptime. The larger systems such as the ceramic filters are able to control multiple pollutants in a single unit in order to minimize cost and complexity.

Industrial Wastewater Treatment:

For customers with water pollution issues, an integrated approach uses market-proven wastewater treatment technologies combined in a single treatment train capable of handling challenging contaminants discharged from industrial facilities or extracted from remediation applications.

From clean, ultra-pure process water to the treatment of murky process effluent, these solutions meet stringent process requirements and discharge limits, deliver a low total cost of ownership, and when possible, reduce the overall carbon footprint through recycling and reuse.
