Buil ing on ExperienceBuilt for Performance

Our experienced engineers will helpyou select the best NOx Control optionto meet your requirements. Since everyJohnson Matthey SCR System is builton cutting-edge technology, your SCRSystem can be customized to ensure themost effective and efficient performancewhile allowing for easy upgrades if conditions should change in the future.

The standard SCR System includes SCRcatalyst, durable housing, mixing duct,injection system components and controlpanel or an optional fully-integrated skid-mount package. The skid-mount optionincludes a converter, injection systemcomponents, electronic controls, urea daytank, compressor and freeze protection.In addition, the skid is assembled at theJohnson Matthey plant and is deliveredready for installation, minimizing installa-tion labor and time. The JM catalyst hous-

ing is much more compact than others inthe marketplace. So, while the JohnsonMatthey SCR catalyst packs maximumpunch in performance, its smaller sizemakes it much easier to install, especiallyin tight spaces.

At the heart of the SCR System is a PC-based control system that is exceptional

for its performance, construction andversatility. With no moving parts, the risk of a breakdown is minimal. The softwarelogic in the Johnson Matthey SCR systemis the most efficient self- diagnostic soft-ware available. It continuously monitorsprocess parameters such as urea flow,pressure, temperature and performancewith the optional NOx analyzer. If aproblem is diagnosed, the software isdesigned to make adjustments, fix theproblem and safeguards against ureaplugging. Upgrades are done simply bymodifying the software, which meansquick and easy compliance with new EPA,ARB or local air agency requirements.

A More Advanced Injection Nozzle

One of the superior features of thisnozzle is its ability to be quickly discon-nected for change-out or for routinecleaning. Unlike other urea injectors,which require the nozzle to be unbolted,the Johnson Matthey unit simplifiesroutine maintenance and saves time.

Flexibility to Meet All of YourEmissions Control Needs

The SCR System can be combined withan Oxidation catalyst to oxidize HC, CO,VOC and HAPs for all lean burn dieselor gas enginesreducing emissions tomeet the most stringent regulations.If you need to reduce particulate matter(PM) as well as HC and CO in a station-ary diesel engineat a consistent rateof 90%+ the SCR System can be com-bined with Johnson Mattheys patentedContinuously Regenerating Technology

(CRT

) particulate filter system. This levelof design flexibility makes the JohnsonMatthey SCR System ideal for retrofit orfor new lean burn engines.

Additional options for the SCR

System include:

Reagent freeze protection devices andprogramming

Catalyst differential pressure monitoring Downstream SCR catalyst temperature

monitoring Ability to monitor and transfer reagent

from bulk storage tank to the day tank

Urea Injection Nozzle

The Johnson Matthey urea injectionnozzle is designed and built foraccurate, plug-free performance andreliability. The self-checking nozzledelivers injection control of eitherurea or aqueous ammonia, with thefollowing benefits:

Air atomizer injection Controlled droplet size for good dis-

tribution and optimal NOx reduction Self-cleaning (air/water purge)

nozzle to prevent deposit buildup Insulation around air pipe to

prevent urea crystallization Injection module complete with

connection fittings Injection rate control bias Redundant delivery pump included Reagent day tank level monitoring

and control Minimal field terminations required

which reduces installation costssignificantly
