Overview
Hot Gas filtration in chemical processes is of prime importance to keep the contaminants away. One such example is Nitric Acid,  production  of which requires an NH3/ Air mixture  to be  filtered to protect the expensive catalyst beds which are the oxidation zones in the reactor.  The filtration is very critical as it helps reduce down-times and safeguards the expensive noble metal catalysts.  Other industries also use hot gas filtration down to micron levels. At Diva Envitec we work closely  with customers to find cost effective and reliable solutions.
