Application of the resonant energy separation effect at natural gas reduction points in order to improve the energy efficiency of the gas distribution system

Abstract

Maintaining the gas temperature and the formation of gas hydrates is one of the main problems in the operation of gas pipelines. Development and implementation of new effective methods for heating the gas during gas reduction will reduce the cost of gas transportation, solve the problem of resource and energy saving in the fuel industry. Study is aimed at increasing the energy efficiency of the natural gas reduction process by using a resonant gas heater to maintain the set temperature at the outlet of the gas distribution station (GDS) and prevent possible hydrate formation and icing of the station equipment. Paper considers the implementation of fireless heating of natural gas and fuel gas savings of heaters due to the introduction of a thermoacoustic reducer, operating on the basis of the Hartmann – Sprenger resonance effect, into the scheme of the reduction unit. By analyzing the existing methods of energy separation and numerical modeling, the effectiveness of the resonant-type energy separation device is substantiated. Modification of the reduction unit by introducing energy separating devices into it will allow general or partial heating of natural gas by its own pressure energy. Developed technology will allow partial (in the future, complete) replacement of heat energy generation at a gas distribution station by burning natural gas.

Analyzing Efficiency of Joint Operation of Gas Separator and Screw Pump on High-viscosity Gas-liquid Mixture

“…Due to the high velocity of the liquid at the outlet of the nozzle 9, a vacuum sufficient for pumping air out of the atmosphere is formed in the receiving chamber 12 of the jet apparatus. The vacuum can be monitored by a pressure sensor 13.…”

“…It is known that the drive for electric screw pump units (ESPU), in one of the known variants, is a submersible electric motor (SEM) used as an electric drive for electric submersible pump units (ESPU), but the difference is that the ESPU operation requires half the angular speed of the shaft rotation. As a rule, the rotor angular velocity required for ESP operation is achieved by manufacturing a four-pole magnetic field drive with a synchronous speed of 1500 rpm or less (13). In contrast to ESPs operating at increased shaft speeds and contributing to the increase in head and delivery, increase in power consumption, for ESPs it is preferable to reduce the rotor speed to reduce the risks of reducing the performance characteristics of the pump due to wear, heating and ensuring the efficiency at the maximum level (14)(15)(16).…”

Use of gas reduction energy at a gas distribution station

“…After studying the vortex effect by Robert Hilsch, the device was called the Rank-Hilsch tube or vortex tube. The effect is to separate a gas or liquid into a hot and cold stream when swirling in a cylindrical or conical chamber [1].…”

Method for Determining the Optimal Capacity of Energy Storage Systems with a Long-Term Forecast of Power Consumption

“…The issues of improving the quality of energy using active DC converters are presented in [38]. The influence of the processes of production and distribution of gas for enterprises of the mineral resource complex, as well as for other large industrial consumers, on the process of power supply is considered in [39].…”
