The processing of the gases within the gas follows some steps, and the example P&ID drawing shows an accessible diagram format of the process. It involves the combustion of oxygen with certain other gases like natural gas, propylene, hydrogen, and nitrogen as a carrier. The drawing of the example here shows a thermal spray process.

The P&ID drawings can make a complicated process look relatively less complicated. The P&ID drawing explains how the process goes on till the company distributed it to the gas stations. The chain begins with the production and import of crude oil, which then goes through the refinery. Here is an example of P&ID drawings, which show the five-tier structure of a gasoline supply chain. Additionally, there are variants forms like :-P, =P, :b, :-b, :-Þ, :Þ, etc.The P&ID shows how the workflow goes, which helps the users identify the disruption in the flow or specific other issues related to the work process structure. The P is often capitalized, but not always. It probably has its roots in long standing cartoon practice of showing stupid/ knocked-out/dazed people with their tongues limply hanging out like a dog's tongue on a hot day. For instance, someone who says in an IM conversation 'I totally flunked the history test today :P' would not be likely to actually let his or her tongue actually loll out thus if the same conversation was held face-to-face. As said earlier, :P is usually is interpreted as a tongue *hanging* out, not protruding straight forward) This emoticon is a less literal depiction of expression than some other emoticons.
