Dry Sorbent Injection (DSI) System for Acid Gas Control

Dry sorbent injection (DSI) systems have been in service for more than 20 years as an effective tool to reduce acid gas levels. Most recently, this technology has been applied to utility, industrial and waste-to-energy applications to mitigate acid gases such as HCl, HF, SO2 and SO3.

Design and Operation

B&W MEGTEC offers expertise in the design and development of injection technology and lance design for optimum reagent and gas mixing. Reagent selection is based on the specific application, unit operating conditions, reagent economics and the pollutants to be controlled.

The material storage, handling and transport system can be designed to handle multiple reagents to offer optimum flexibility. In addition, each application will vary depending on the pollutants to be controlled, available residence time and the type of particulate collection device in place.
