Practical equations calculate gas flow rates through venturi valves

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 ...

ISA75.01, Control Valve Sizing Equations

Consider all items related to control valve sizing standards, including future reaffirmation or revision to ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, and ...

Flow Valves

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

Method yields more conservative estimates of DRA effectiveness

Drag-reducing additives (DRA) alone are not enough to meet increased flow demand given pipeline codes and operational constraints, despite being a very practical means of resolving bottleneck ...
