Eliminating Need For Gas Preheat In Pressure Regulation

摘要

Universal Vortex, Inc. offers proprietary technology that provides non-freeze pressure regulation of non-preheated gas. This substantially reduces or even eliminates energy consumption that is routinely required to preheat the high-pressure gas upstream of its pressure regulation. The UVI technology allows increasing the pressure regulated gas temperature-also without applying any external source of energy. The technique is based on using the proprietary self-heating vortex tube as a primary pressure regulator that follows with the energy redistribution in the pressure regulated gas. The Vortex Tube (VT) is a specially designed cylindrical device with no moving parts. It takes high-pressure gas and, in the course of its depressurizing, converts (vortex phenomenon) the inlet gas flow energy into two low pressure streams - cold and hot -which exit the VT separately. The generated hot gas, prior to exiting the VT, is used to warm the unit's inlet orifice (spot heating) thus eliminating the likelihood of depressurized gas freezing (self-heating provision). Intensity of the vortex energy division depends on the ratio of the VT inlet and outlet pressures and is not affected by the gas flow rate through the unit. The concept design of the Vortex Pressure Regulation Station (VPRS) that retains the existing PRS is shown in Fig 1.
