Knight,

 

The auto-ignition temperature of compressed natural gas is 540°C which is quite high. Auto-ignition tmperature does tend to decrease with increase in pressure but not appreciably. In your case (195 psig), the auto-ignition temperature would remain near about the same temperature as 540°C.

Thanks Ankur for your appreciated help

I'm curious as to why you ask the question. I don't know of any process that woud involve a natural gas and oxygen mixture at elevated pressure, except in a combution chamber as for a gas turbine. But in this instance, the mixture is achieved in the combustion chamber, not before. And the intent is to combust the mixture.
