US Patent Application for NON-METHANE HYDROCARBON

A method of assessing non-methane hydrocarbon (NMHC) conversion efficiency in a diesel after-treatment (AT) system having a diesel oxidation catalyst (DOC) arranged upstream of a diesel particulate filter (DPF) includes regenerating the AT system. Additionally, the method monitors DOC inlet and outlet temperatures during the regeneration. The method also assesses whether the DOC is

Source apportionment of non-methane hydrocarbons, NOx

Apr 18, 2018· A non-negative matrix factorization (NMF) analysis revealed six consistent source factors, of which two were associated with pre-existing local sources from car traffic and industry, three with regional oil and gas exploration, and one with diesel emissions.

Boiler Combustion | CleanBoiler.org

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

What Are Diesel Emissions

Gases found in diesel emissions including carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide and many other compounds have their PELs set by occupational health and safety authorities. Diesel particulate matter has also been listed by a growing number of occupational health and safety standards as a toxic air contaminant.

Gaseous Emissions - DieselNet

In engine emission standards, hydrocarbons are commonly regulated as either total hydrocarbons (THC), or as non-methane hydrocarbons (NMHC), the latter category excluding the simplest hydrocarbon methane (CH 4) due to its different atmospheric reactivity from longer chain hydrocarbons. Even though the concentration of methane in diesel exhaust

European Union Emissions Standards - Lubrizol

Heavy-duty diesel trucks. The 13 mode steady state cycle test (ECE-R49) used for the Euro I and Euro II standards was replaced by two tests in Euro III, a stationary cycle test (ESC) and a transient cycle test (ETC), which evaluates non-methane hydrocarbons (NMHC) rather than all HC. The ETC test also evaluates methane emissions; however,
