Video compares Equilibar valve to traditional valve in two phase flow

Video Compares Equilibar and Traditional BPR Performance for Two-Phase Flow of Liquid and Gas

  • image for mixed phase video

Equilibar has released a new video that demonstrates how its dome-loaded multiple orifice technology compares to a traditional spring-loaded back pressure regulator when controlling a process that involves mixed-phase flow of gas and liquid together.

Filmed in Equilibar’s engineering laboratory, the video first demonstrates the performance of a high quality knob adjusted mechanical back pressure regulator as gas and liquid are injected into the controlled pressure port. The scenario is then repeated using an Equilibar dome-loaded multiple orifice back pressure regulator. Process Engineer Ryan Heffner uses schematics and computer display to explain exactly what is happening and why.

 

 

A high pressure water pump is used to inject liquid into the controlled pressure port (inlet port) of the back pressure regulator. The water then mixes with pressurized nitrogen gas to create a dual phase liquid-and-gas mixture. The controlled pressure is read by a pressure transducer and displayed on a pressure waveform on the computer. In the demonstration, the traditional spring-loaded regulator had pressure variations of around one Bar with the relatively low viscosity water media. The Equilibar BPR held the pressure steady and at set point with both gas and liquid phases.

Equilibar’s patented back pressure regulators and vacuum control valves feature a patented technology that offers multiple advantages for complex applications. In addition to providing superior performance for mixed-phase flow, Equilibar products are more precise, react instantaneously, accommodate wide flow rate ranges and are suitable for severe service conditions. Equilibar products may offer superior accuracy, wetted materials / corrosion resistance, easy integration with manual and electronic pressure controllers, and other application advantages. Equilibar products are not right for every application but are well suited for applications that require peak performance despite complex challenges.
