Air Emissions & Energy Efficiency

Air Emissions & Energy Efficiency

It is essential for your factory to comply with emission limits on dust, vapors, and odors. Addressing a combination of these emission types requires a good, integrated design to prevent an unnecessary maintenance burden in the future. In our experience, factory processes and equipment often change rapidly. For this reason, JOA filter units are built as easily extendable modules. Choosing the right filter principle and filter media is key for a long-term sustainable solution.
In the 450 projects we have executed in the last decade, JOA has made an effort to reduce waste-water streams. Therefore, we prefer “dry” filter techniques over wet scrubbers. We only apply wet scrubbers when the effluent waste-water stream is recycled directly into the production process. Dryer emission in food and pharmaceutical applications have shown a great opportunity for effective energy recovery, producing steam and/or hot water. We also provide fully integrated exhaust-air treatment systems.

How can you comply with emission limits and recover energy efficiently at the same time?

A good example of this is ammonium sulfate fertilizer plants. By utilizing JOA inline-venturi scrubber effluent as process make-up water, the wet-scrubbing system in this case delivers both environmental and economic benefits. Another example is direct energy recovery. We use the exhaust air from driers and flash towers to recover the energy for direct steam or hot water generation. As a result, up to 70% energy recovery efficiency is possible.

Alternative technologies to choose

Our Delft-based laboratories focus on providing customized filter solutions in standardized (economic) filter housings. For instance, alternative filter technologies such as acoustic agglomeration and photo catalytic oxidation are helping to change the somewhat conservative filter industry by allowing effective dust and fume emission control. Have a look at the JOA air filtration leaflets on fume, vapor, odor, and aerosol filters:

  • JOA Inline Venturi Scrubbers for Vapor Elimination and Energy Recovery
  • JHF – Coalescer-belt Filter
  • JPCO – Photo catalytic Oxidation
  • JOA Diamond Activated Carbon Filters

Dust and UFP Filters:

  • JOA Modular Dust Filters: JDF, JRF, and Inline Venturi
  • JAA – Ultra-fine Particulate Treatment Through Acoustic Agglomeration
  • JPF (ACiP) – Product Recovery (ACiP) Filters and Deflector/De-gritter hoods
  • JOA Micro-climates (Local Clean Rooms) for High-end Product Protection

In summary, we are confident that our range of standardized filters can meet your requirements. Our product owners and consultants are ready to get involved in designing your air pollution control system.
