  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...
