  • LGD F200 - Designed for easy zeroing and span adjustments

    Regular zeroing and span adjustments to gas analyzers in the field are suggested and required for a variety of reasons. Compliance to environmental standards, e.g. those outlined in the US EPA (40 CFR) or EN 14181 is an important factor. Special application conditions, e.g. a varying gas matrix or compensating for pressure effects can be additional reasons, where a zeroing and span adjustment ...

  • Ammonia removal from landfill leachate by struvite formation: an alarming concentration of phosphorus in the treated effluent

    This study examined the removal of ammonia nitrogen from the leachate of a landfill site using the chemical precipitation of struvite (MgNH4PO4.6H2O). This procedure achieved a reduction in the ammonia concentration that was higher than 99% when the molar ratio of 1.8:1.0:1.4 for Mg2+:NH4+:PO43− ...

  • Are your MI and reliablility programs competing for resources?

    A number of refineries and chemical processing facilities have not yet realized the potential synergy between regulatory-driven mechanical integrity (MI) programs and facility-wide reliability programs. The tendency at many facilities is to keep these two initiatives separate, which typically results in a competition for precious maintenance and inspection resources as well as management ...
