Ecopure® VAR
– Exhaust Gas and Liquid Oxidizer
Recently there has been increasing pressure on the chemical
industry to effectively control emission sources. The Dürr Ecopure® VAR oxidizer system provides a technically
advanced solution to this difficult problem.
The Ecopure® VAR technology centers around a unique thermal
reactor capable of accepting nearly any combination of liquid or vapor waste.
The key element of the system is a proprietary integral burner/combustion
chamber designed to operate over a wide range of temperatures and as high as
2,300 °F with residence times as long as 2.0 seconds thereby insuring complete
oxidization of nearly all known VOCs and HAPs.
The combination burner and retention chamber are only the
beginning of a complete system as secondary heat recovery along with NOx and
acid gas removal is common place. A typical system will incorporate the
combustion chamber followed by a waste heat recovery boiler followed by NOx reduction
and finally an acid gas scrubber.
Among distinguished advantages of the Dürr Ecopure® VAR system is:
·
Ability
to operate above the lower explosive limits of the gases or vapors
·
Operation
at near “0” excess Oxygen
·
Operation
using waste or refuse fuels, liquid or gaseous
Oxidation
of halogenated, nitrogenated or sulfonated compounds have been especially
difficult to control in the past and now with the application of the Ecopure® VAR, reliable control is both affordable and
dependable. With an install base of 80 systems globally, the Ecopure® VAR is particularly attractive as a control
method not only the chemical industry, but for pharmaceutical and petrochemical
batch vents, rich process vents, and chlorinated streams.Visit
