Exhaust Gas Treatment for Emergency Power Systems in Data Centers

A reliable emergency power supply is essential for the availability of data centers. ProMinent offers project-specific storage and metering solutions for urea or ammonia water, which are used in SCR (selective catalytic reduction) processes to reduce nitrogen oxide emissions from emergency power generators.

Emergency Power Supply and Emissions Reduction

Diesel-powered emergency generators are frequently used to maintain the power supply during prolonged grid outages. The exhaust gases produced during operation may contain nitrogen oxides, which must be purified before discharge, depending on applicable environmental regulations.

Precise Dosing for SCR Processes

In selective catalytic reduction, a defined amount of urea solution or ammonia water is dosed into the exhaust gas stream. Accurate and reliable dosing is essential for the reduction process and must be designed to meet the required flow rate, pressure, chemical concentration, and safety requirements.

Project-Specific Systems from Storage to Injection

ProMinent designs complete packages for chemical handling and dosing, which may include unloading equipment, storage tanks, measurement technology, safety devices, pumps, dosing skids, and local control panels. The final configuration is selected according to the project specifications.
