  • Improving the reliability of closed chamber methodologies for methane emissions measurement in treatment wetlands

    Non-homogeneous mixing of methane (NHM) within closed chambers was studied under laboratory conditions. The experimental set-up consisted of a PVC vented chamber of 5.3 litres of effective volume fitted with a power-adjustable 12 V fan. NHM within the chamber was studied according to fan position (top vs lateral), fan airflow strength (23 vs 80 cubic feet per minute) and the mixing time before ...

  • Case study - Better maintenance starts with better documentation

    OXIDIZER SERVICE SERIES: PART 1 Your oxidizer system is both a significant investment in - and a long term commitment to - environmental compliance. Part of properly servicing your oxidizer system is maintaining the design documentation associated with that system. In the oxidizer design world, National Fire Protection Association (NFPA) standards are often viewed as good practice. However, not ...

  • Chemical Industry: Sale of by-Product HCl Covers Cost of Emission Control System Problem Case Study

    Some of the specialty chemical processes at a major chemical manufacturer’s plant result in considerable HCl loading in the off-gas. The HCl must be removed before the off-gas can be discharged to the atmosphere. Production of saleable by-product HCl solution was an important goal when looking for a high-efficiency HCl removal system. The company wanted to achieve a very low level of ...
