In-line Monitoring of Gaseous Oxygen
A French pharmaceutical company has made a major upgrade investment in a plant for manufacturing pharmaceutical active principles. This upgrade includes facilities to reduce atmospheric emissions, including emissions of VOCs, and the ability to save energy by recovering the heat of combustion.
VOCs are a large class of organic compounds characterized by normally being in the gaseous state or evaporating readily at standard temperature and pressure (20 °C, 105 Pa). As to toxicity, common VOCs can give rise to various symptoms and effects ranging from mild irritation to severe respiratory distress and some are suspected carcinogens. VOC emissions are governed by EU Directive 99/13, originally issued March 13, 1999, which sets forth limits on point source (stack) and diffuse emissions with special provisions for certain more toxic solvents requiring reduction or substitution.
