Odours and Toxic Gas Control

Emission Control

To prevent nuisance odours and toxic gases from entering both the workplace and the environment Sutcliffe Speakman can offer solutions derived from the following technologies; the SC Bioreactor™ and activated carbon adsorption.

Activated Carbon Adsorption
A range of 'state-of-the-art' high efficiency, zero bypass adsorption systems is available. Specific impregnants can be incorporated onto the activated carbon surfaces to chemisorb inorganic compounds such as Sulphides and Mercury.

SC Bioreactor™
The SC Bioreactor™ is also suitable for the removal, from the air, of certain nuisance odours such as Hydrogen Sulphide, Ammonia and Mercaptans.

Individual Designs

Sutcliffe Speakman designs and installs systems that are individually designed to meet client needs, or standard designs that have been specifically adapted. To ensure optimum performance, systems are purpose designed in-house for each application. Specific features include:

  • Sutcliffe Speakman designed air valves
  • 'state-of-the-art' control systems
  • plant performance data logging
  • data processing to comply with regulations
  • range of adsorber designs

Diverse Requirements

such as:
  • air flows from 250Nm³/h to 300,00Nm³/h
  • solvent rates from 5kg/h to 10,000kg/h
  • low air flows with high solvent loadings
  • complex VOC mixtures
  • waste water clean up
  • corrosive solvent mixures
  • combinations of the above

PROBLEM
Although below legislated limits, small quantities of PCBs were being emitted from a process which dismantled and destroyed old transformers and capacitors.

PCB Emission Control System

SOLUTION
A complete extraction system was installed to reduce the fugitive PCB levels in the workplace, whilst an annular bed adsorber, capable of dealing with 20,000m³/hr airflow reduced the emmisions of PCBs from 5 microgrammes/m³ to trace levels only.
