Dry Sorbent Injection (DSI)

Proven low captial cost solution to meeting your SO2, SO3 & HCI emissons performance

There are a number of technologies available to help industrial boiler operators, fossil fueled electrical generation facilities, and biomass plants meet recently established and emerging EPA requirements. However, determining the most cost-effective method of Hg, HCI, HF, SO2, and SO3 mitigation can be a daunting task. Nol-Tec has been a pioneer in the development of dry sorbent injection technology, a low capital cost solution to acid gas mitigation.

Nol-Tec DSI – The Difference

Nol-Tec takes out the guesswork when designing the most optimal DSI solution for you. From what type of sorbent to inject to the location of your stack if you tell us what results you want to see we will design a process from start to delivery.

Other areas of expertise include:
• Advanced technology for sorbent distribution including Sorb-Tec and resistive splitting
• Our continuous weight metering system accurately delivers sorbent at desired rates
• Ability to leverage Complex Fluid Dynamics (CFD) to provide a more accurate and predictive tool for emission reduction.

But don’t take our word for it: with our portable DSI testing services, we can bring our dry sorbent injection technology into your facility to effectively verify the proper sorbent, chemical use rate, and injection location. In this way we can determine your emissions mitigation results and the ideal system configuration before you purchase a permanent system. We can also provide this as a turnkey service so you don’t have to worry about sorbent supply and stack testing.
