DEC Envirosystems

Your Partner in emission control…

The dust load of the flue gas inside a Cement pyro system is extreme compared to other industrial combustion systems. A catalyst for NOx removal is thus exposed to very harsh conditions in a Cement Plant; not just because of the highly abrasive dust, but it also contains elements that can “poison” a deNOx catalyst and reduce its activity. SNCR is thus the most widespread NOx reduction technology for Cement applications. Even SNCR equipment must be designed for the high temperatures and the dusty environment of the Cement Plants.

For Cement Plants with a high baseline ammonia emission and/or high SO2 emission, an SCR Catalyst may be required to avoid visible plumes, dew point corrosion and deposits of Ammonium Bisulphate in Filters/on Fans and may even solve problems with emissions of VOC,TOC,PAH or Dioxins/Furans.

DEC Envirosystems (A Division of DEC Engineering & Constructions Pvt. Ltd.) in association with Technology Collaborator can provide optimized deNOx technology and solutions for Cement Plants. DEC Envirosystems focuses on providing solutions for deNOx to the Cement & Power and other Combustion systems - from taking up Plant studies to commissioning including design & engineering, supply & installation in association with their technology Partner on virtually all emission related matters. The Division is headed by Subhajit Hazra (CEO) who has around four decades of experience in the Operations & Project execution of Metallurgical Units in India & Central Africa and the Division is supported by an able team of designers and personnel for Project execution.

The deNOx installations being offered by DEC Envirosystems is designed to last and the main advantages of Technology Collaborator include:

    • Providing SNCR systems for concentrated & dilute solutions of technical Urea or Ammonia
    • No dilution water - resulting in low cost of installation, operation & maintenance; reduced risk of dew point corrosion
    • No increase in flue gas flow, no drop in flue gas temperatures and no un-necessary heat or power consumption
    • Unique Injectors as a result of continuous development featuring unsurpassed performance and durability. Injector features include:
    • Adjustable insertion depth
    • Adjustable droplet size and spray pattern on Site
    • Quick coupling for easy mounting and maintenance
