SIMASOLVENT® - For exhaust air purification

"Schematic representation of the energy-efficient SimaSolvent® exhaust air purification process with heat pump, heat recovery, activated carbon containers and recirculation of the purified air into the production cycle."

The energy-efficient Alternative

The SimaSolvent® exhaust air purification system is based on the condensation process. The core component of the system is the use of a highly efficient industrial heat pump, which acts as a refrigeration unit. Depending on the application, this can be used either for the direct condensation of volatile organic compounds or in conjunction with an adsorption stage (activated carbon). In contrast to conventional condensation units, the heat energy generated is not released into the environment but can be reused as process heat.

Compared to conventional system technologies, this has the following advantages:

  • Very high energy efficiency, as all the energy is used
  • No additional (direct) emissions
  • Any condensate produced can be reused, resulting in potential savings
  • Low maintenance costs
  • Simplified preparation of a solvent balance, as the separation performance of the VOCs can be measured via the amount of condensate.

  • WHAT IS MEANT BY VOCS?

    VOC is the abbreviation for volatile organic compounds (volatile organic compounds). This means that these substances evaporate at low temperatures. The point at which a substance is considered a VOC depends on national definitions.

  • WHERE ARE VOCS RELEASED?

    Most of the VOCs released by humans are now attributable to the use of solvents.

  • THESE SUBSTANCES ARE USED IN A VARIETY OF WAYS, E.G:
    • in coating technology
    • in the textile industry
    • in the printing industry
    • in the production of adhesives
    • for cleaning purposes
  • WHEN MUST MEASURES TO REDUCE VOC EMISSIONS BE IMPLEMENTED?

    This depends crucially on the annual consumption of solvents and the industry in which you operate. Below an industry-specific lower limit, there is no legal obligation. However, if this limit is exceeded, emission reduction measures must be taken.

  • WHAT ARE THE OPTIONS FOR REDUCING VOCS EMISSIONS?

    First and foremost, VOC emitters should try to minimize the use of organic solvents. In coating technology, for example, more and more water-based paints are being used that contain no or only very small quantities of VOCs.

    Although considerable progress has been made in recent years, it is often not possible to make decisive adjustments to production processes. In such cases, downstream purification processes must be used to clean the contaminated material flows (waste water, exhaust air) as far as possible before they leave the production facility.
