Ammonia flow is in general controlled based on NOx measurements taken from the gas stream or preexisting performance curves from an engine manufacturer (in the case of gas turbines and reciprocating engines). Typically, all future operating conditions must be known beforehand to properly design and tune an SCR system.
ISGEC Heavy Engineering Ltd (/ ˈ ɪ z dʒ ɛ k / IZ-jek; [3] formerly known as Indian Sugar and General Engineering Corporation) is an Indian heavy engineering company. Established in 1933 as Saraswati Sugar Syndicate, the company held a revenue of ₹ 5,477 crore (US$660 million) in 2021 with exports of approximately 91 countries. [4]
A NO x adsorber is designed to reduce oxides of nitrogen emitted in the exhaust gas of a lean burn internal combustion engine.Lean burn engines, particularly diesels, present a special challenge to emission control system designers because of the relatively high levels of O 2 (atmospheric oxygen) in the exhaust gas.

In atmospheric chemistry, NO x is shorthand for nitric oxide (NO) and nitrogen dioxide (NO 2), the nitrogen oxides that are most relevant for air pollution. [1] [2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone.
In the early 1980s Philip Hill, then a University of British Columbia mechanical engineering professor, sought improvements to natural gas combustion in engines. [1] Hill's team of graduate students and research engineers focused on natural gas as a fuel in diesel engines to reduce emissions of nitrogen oxides (NOx) and harmful atmospheric particulate matter.
The company was established by the Jain family in the year 1963, as Industrial Oxygen Company Private Limited in Pune, India.In 1999, Air Products & Chemicals Inc., acquired a 50 percent equity stake in the company, and a new entity was incorporated; INOX Air Products.
The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
