With the topic of the moment very much based around a reduction of world emissions (Kyoto Protocol), IMS has further developed their exhaust gas SCR systems to reduce the nitrous oxide emissions that occur during the running of an engine.
Nitrogen oxide, aka NOx, is a group of different gases made up of different levels of oxygen and nitrogen. Two of the most common nitrogen oxides, nitrogen dioxide and nitric oxide NOx, are given off in many forms, such as smog or particles.
But what environmental problems are created by nitrogen oxide pollution? Some examples are the formation of ground level ozone (smog), creation of acid rain and water quality deterioration. In the air, NOx mixes readily with common organic chemicals to form toxic products. All of these cause a gradual rise in global warming, which will lead to increased risks to human health, a rise in sea levels and other adverse changes to plant and animal habitats.
IMS can now supply three major kinds of catalytic converters, each of which is capable of an emission reduction of up to 99% in each of the following categories: single stage oxidation – carbon monoxide (CO) is reduced; two-stage oxidation – carbon monoxide and hydrocarbons (HC) are reduced; three-stage SCR – in addition to CO and HC the level of nitrous oxides (N2O) are reduced.
Each of the above converters can be used within various applications such as locomotives and railway vehicles, construction machines, ships and yachts, tractors, commercial vehicles and buses, electrical and generator power plants, combined heat and power plants and CO2 fertilisation for greenhouses and waste incinerators.
Only stainless steel substrates are used and the innovative construction ensures the maximum surface area for the coating of the precious metals that cause the chemical reaction. Units are designed to meet the most stringent legislation. CO and HC catalysts can be installed either as stand alone units with coned inlet/outlet for insertion into the exhaust pipe work or as an integral part of an exhaust gas silencer, thereby eliminating the need for a separate housing.
As of January, 183 countries have accepted the Kyoto Protocol. For further information contact Dan Gallacher at IMS on +44 (0) 1162 604985 or e-mail sales@silencers.co.uk.
