UNSPSC 40161607: Flue gas desulphurization system

A type of device that has installed for the purpose of preventing the atmospheric pollution by removing the sulfur oxides with the process of absorption, oxidation, deoxidation, adsorption and others of the exhaust gas generated from the combustion process of thermal power plant and industrial boiler that uses the fuel of coal or distillation.

UNSPSC 40161607 Flue gas desulphurization system is a Commodity code under which state and local governments procure refrigerant recovery and gas extraction services from EPA-certified contractors. The code's recent activity reflects municipal environmental compliance and sustainable asset management: the City of Tucson's Environmental and General Services Division issued RFP No. 240011 seeking EPA-certified refrigerant reclaimers to extract refrigerant gases (Freon, mixed gas, refrigerant) from approximately 50 appliance and HVAC units per week at the Los Reales Sustainability Campus, with extraction required at minimum every two weeks and full documentation of gas destruction or recycling. Work of this scope—extracting, recovering, and destroying or recycling refrigerant gases from collected municipal equipment under EPA oversight—defines the actual procurement activity under this code. Issuing bodies include city environmental services divisions managing sustainable asset disposition and regulatory compliance.

The code shows limited recent state-local activity in the source data: only the Tucson RFP appears in the recent-opportunities block. The City of Tucson Environmental and General Services Division is the sole named buyer. The RFP closes on September 19, 2024, with a pre-submittal conference scheduled for March 19, 2024. The contract term is one year with potential for four additional one-year renewals. Pricing is structured as line items for removal labor (by gas type and time-of-day rates) rather than a fixed budget, and the Federal Transit Administration Terms and Conditions referenced suggest DBE participation provisions may apply. This code remains narrow in state-local procurement scope; recent opportunities are sparse and concentrated in Arizona municipal environmental operations.
