Wastewater streams from petroleum refineries present some of the largest ranges of variation in contaminant loadings and contain some of the toughest contaminant profiles to treat. These factors render the wastewater treatment processes difficult to control. The most challenging area of wastewater process control in petroleum refining lies in biological treatment, due to the vast number of control...

Regulatory authorities around the world require continuous emissions monitoring of certain pollutants from large combustion sources. There are two main technologies for monitoring these emissions on a continuous basis — the more traditional one relies on sampling and analyzing exhaust gases from a continuous emissions monitoring system (CEMS); and the newer one relies on software that uses...

Water systems are common in the chemical process industries (CPI). Mixing, heating, concentrating and evaporating water in these systems will often result in an accumulation of inorganic scale, which can markedly decrease process-system efficiency. Scale inhibitors are chemical substances that, when added to industrial water at very low levels, act to reduce or prevent the formation of scale. Over the past...
