Dioxin destruction
CRI provides technology for the catalytic destruction of dioxins and furans from municipal solid and hazardous liquid waste incineration facilities. CRI catalyst technology allows customers to cost-effectively meet the most stringent worldwide dioxin emission requirements. From installation to ongoing maintenance, the Shell Dioxin Destruction System (SDDS) minimises the costs and complexity of dioxin abatement.
SDDS
SDDS from CRI is the most cost-effective, efficient and complete low-temperature technology for flue gas dioxin emission destruction. Its LFR-based design is proven in numerous incineration and industrial environments, offering excellent cost/performance benefits compared to other dioxin emission control technologies along with the ability to operate with greater energy efficiency.
By sharing our experience and operating per CRI guidelines, your dioxin destruction catalyst performance can be guaranteed.

Municipal Waste Incineration
CRI catalytic dioxin destruction technology has been successfully applied to both liquid waste incinerators after the wet acid gas scrubber and to solid waste incinerators after the acid gas and particulate removal systems.
Low operating temperature and the ability to design for low pressure drop allow the Shell Dioxin Destruction System to be positioned at the tail end of most existing processes, just prior to the stack

CCR
A durable and robust steel module and long-lasting catalyst allows your system to run reliably and with minimal maintenance downtime or catalyst renewal.
The use of SDDS enables high conversion of dioxin at relatively low operating temperature and with low pressure drop across the lateral flow reactor (LFR) which results in minimal impact on production.
Industrial Waste Incineration
The combination of high catalyst activity and low pressure drop makes the SDDS highly efficient at dioxin destruction. From the highest inlet concentrations, the system can achieve over 99.9% destruction of dioxins and furans, down to the lowest worldwide regulated emission limit.
The compact, lightweight nature of the system allows easy retrofit onto existing facilities where space is limited. Installation at the end of the process results in significant savings in installation and operating costs, with minimal downtime for installation.
