  • Managing continuous emissions monitoring systems

    With recent rulemaking governing compliance determinations in regards to the emissions of nitrogen oxides (NOx) and highly reactive volatile organic compounds (HRVOCs), the Texas Commission on Environmental Quality (TCEQ) required more frequent monitoring which resulted in the installation of more monitoring systems at the facility. This large Gulf Coast refinery decided to utilize the ...

  • Who Needs Continuous Emissions Monitoring?

    Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • A constant eye on emissions

    Due to increasingly rigorous requirements for regulatory and permit compliance, organisations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

    The safety of V-1 Immunitor (V1) has been investigated. L929; BHK; Vero; Caco-2 and CEM-SS cells have not shown cytotoxicity even at 10 mg/ml dose. Ames' mutagenicity and micronucleus genotoxicity tests came out negative at 50 mg and 2000 mg/kg doses in Salmonella and bone marrow of IRC mice. Acute and chronic dosing of V1 to Swiss albino mice and Spague Dawley rats failed to cause any deaths. ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...
