The Technology of Isothermal Pressure Regulation of Natural Gas Based on Temperature Stratification

Abstract

The paper introduces a new technology of isothermal pressure regulation of natural gas based on temperature stratification which combines the vortex effect temperature stratification and supersonic gas-dynamic temperature stratification. The authors simulate physical and numerical controllers work. As a result of the experiments the most effective operating principles of the isothermal controller (based on the vortex tube temperature stratification) are introduced. The paper also presents calculations of the described pressure regulation controller while applying gas-dynamic temperature stratification. The authors conclude that the usage of the introduced technology of isothermal pressure regulation of natural gas will reduce expenses of gas transportation systems for their own needs (by 0,08-0,2 % of natural gas to their carrying capacity).
