Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

A method has been developed that allows direct, accurate calculation of recovery efficiency for Claus sulfur-recovery units (SRU). The calculation combines feed-gas data and tail-gas composition to ...

Prior to placing newly installed natural gas piping and valves in service, systems must be properly cleaned to remove potentially damaging foreign material that is inherently left behind during ...
