In chemical plants, oil refineries and steel mills wet gas scrubbers play a significant role in preventing pollutants being released to the atmosphere. However, use of inappropriate analytical sensors compromises their efficiency potentially leading to breaches in regulations and damage to the environment. In a new white paper, Mettler Toledo explains the importance of choosing the correct sensors in scrubber applications.

 Many chemical and petrochemical processes produce gaseous emissions that contain polluting substances, such as sulphur dioxide and hydrogen chloride. If released into the atmosphere, these compounds would violate regulations and cause serious environmental damage as both are components of acid rain. They also may lead to corrosion and scaling of plant equipment and costly maintenance.
