Abstract: This invention provides a gas wave pressure regulation method and apparatus, gaseous wave pressure regulator (GWPR), associated with a pressure energy recovery system which can be used in the processes of petrochemical and liquid natural gas (LNG) industries to recover the lost energy in a regulating process where a pressure regulation is needed to reduce the pressure level fitting the operating conditions, but the spontaneous temperature is undesirable. The said method and apparatus employ a mechanism creating a unsteady periodic flow by means of gaseous wave resonant interactions to convert the energy between the pressure drop into the form of heat without using any moving parts. The said heat is reused inside the GWPR to eliminate or diminish the temperature drop associated with the pressure regulation. The said pressure energy recovery system comprises a primary GWPR followed by a primary heat exchanger, and a secondary GWPR linked by a secondary heat exchanger operated in series.
