Q-DOC Diesel Oxidation Converters

Nett Technologies offers a line of diesel oxidation catalyst (DOC) converters specifically designed for large, stationary industrial engines. Oxidation converters are used for lean-burn engines (diesel/CNG) to meet emission standards for carbon monoxide (CO), hydrocarbons (HC) and the SOF fraction of diesel particulate matter (DPM/PM).

Q-DOC - Technology

Q-DOC™ oxidation catalytic converters utilize a precious metal catalyst bonded to a monolithic, flow-through catalyst core. The cores are made of corrugated, high temperature resistant stainless steel foil packaged into a rugged stainless steel container. Nett’s Q-DOC™ series products either in stand-alone or silencer configurations are specifically designed to meet the requirements of the EPA’s RICE NESHAP regulations. Applications include 2 or 4-stroke lean-burn compression ignition (CI) and spark ignited (SI) engines used in power generation, gas compression, co-generation, pumping stations and irrigation facilities.

Q-DOC - Performance

The Q-DOC™ oxidation catalyst is designed to promote the oxidation of hazardous air pollutants (HAPs) such as carbon monoxide (CO) and hydrocarbons (HC). CO and non-methane hydrocarbons (NMHC) conversion levels of 90 to 99% are typical. In diesel engine applications, Q-DOC™ also reduces particulate matter (PM) emissions by up to 40% for 2-stroke engines and up to 30% for 4-stroke.

The Q-DOC™ Silencer series is available in industry-standard sound-attenuation grades to meet state or federal regulations. Models are available in heavy-gauge mild, aluminized and stainless steel materials.

 

Q-DOC - Designs and Options

Nett's Q-DOC™ series products are available in either stand-alone or silencer configurations. Stand-alone designs are universal-fit units for controlling exhaust emissions only. Silencer configurations pair the Q-DOC emissions control unit with silencers available in industry-standard sound-attenuation grades (industrial, residential, critial, hospital, etc.) to meet state or federal regulations. Models are available in heavy-gauge mild, aluminized and stainless steel materials.
