Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible. Historically, the primary use of oxy-fuel combustion has been in welding and cutting of metals.
Advantages:
1. The mass and volume of the…Read more

MON is Motor octane number, which is measured at higher intake temperatures (preheated fuel) and higher engine speed (900 RPM). Its purpose is to measure the octane number near the actual condition at the high speed of the car engine.

In Oil refinery Benzene is mainly present in aromatics waste tanks, reactors, close drain vessels. In addition, all other confined spaces should also be taken seriously.
Its exposure can be avoided in confined spaces by;
1. Monotiring through Benzene meter or…Read more
