Question

CNG is said to be odourless. How do we detect its leakage?​

Answer 1

Explanation:

Because CNG is 90 percent methane, it is naturally odorless, so Mercaptan (the stuff that gives gas the familiar gas smell) is added so the average person can detect a leak. The pungent smell can first be detected at 16 times lower than the level that will support combustion.
