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 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.

Introduction & Dioxin Voiceover
The world we live in today is full of amazing achievements most of which wouldn’t be possible without our strong industrial manufacturing infrastructure.
And while these plants and factories work hard to deliver the goods and services we depend on, we need to work equally as hard to minimize the emissions they can sometimes produce, our world depends on it.
That is where CRI comes in. Every day CRI Catalyst, a subsidiary of Royal Dutch Shell researches and implements new innovative ways to help make reducing emissions a reality.
And now through our revolutionary catalytic reduction process, businesses can continue to produce the goods we need while reducing air pollution and helping create safer and cleaner environments.
Discover all of the ways that CRI can help you play your part in ensuring a cleaner environment for us all.
Dioxins are a group of chemical compounds that are known to produce the highest toxicity of any chemical.
Dioxins are produced as a result of combustion processes like commercial or municipal waste incineration and from burning fuels such as wood and coal.
If not kept in check, potentially harmful Dioxins can work their way into the food chain through ground water, building up.
But there is a way to help curb these effects.
Let’s take a look at a solid waste incinerator. While incinerating waste helps decrease the load on the world’s landfills, it also produces dioxins and furans.
The Shell Dioxin Destruction System enables dioxins to be reduced to extremely low levels while maintaining low flue gas temperatures. The two key features of the system are the proprietary high-activity catalyst from CRI and the Lateral Flow Reactor module - LFR - which contains the catalyst.
In this scenario flue gas leaving the incinerator enters the LFR through numerous gas inlet channels. As it travels laterally through the catalyst layers the dioxin compounds are converted to CO2, H20, and HCL.
The SDDS offers a simple and cost-effective design that can be easily retrofitted to many existing applications.
CRI catalyst systems have demonstrated 99.9%+ removal of dioxins and furans, meeting or exceeding all current global regulations. Now, that's a cool way to create a cleaner environment.

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.
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.
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.
