The majority of process operations involve material that is in a gaseous state. Temperatures can range from –150°F to over 1,400°F with pressures ranging from a vacuum to over 2,000 psi. These conditions are not isolated extremes, but rather conditions that are typically encountered in various hydrocarbon processing units. Given this wide range of operating conditions, it is critical that a process technologist understand the behavior of gases under extreme conditions. ...
