RESOURCE-SAVING USE OF THE ENERGY OF COMPRESSED NATURAL GAS USED AS A COOLANT IN THE HEATING SYSTEM OF AN INDUSTRIAL BUILDING

Abstract

The analysis of the literature has shown that there are no effective energy-saving natural gas treatment installations in terms of ensuring rated parameters of gas specific humidity. Natural gas dewatering used at compressor stations does not guarantee the permissible values of natural gas humidity, which has a negative impact on the gas calorific value and affects the energy efficiency of the used gas equipment In order to ensure the desired natural gas parameters there is a need to develop a method of natural gas aftertreatment at gas-distributing stations that will be sufficient to maintain appropriate natural gas humidity parameters. The authors have developed a mathematical model of heat transfer from the natural gas whirling current to the heated space air in a vortex heat exchanger. This model has been used to develop a schematic diagram of equipment layout and control devices that are able to ensure an energy-saving technology of supplying the coolant to its final users with required natural gas humidity parameters. The paper contains a design solution of an industrial building energy-saving integrated heating system that utilizes the pressure drop at the gas-distribution plant and can increase energy efficiency of natural gas aftertreatment and dewatering before the gas is supplied to its user. There is a schematic diagram of a gas-distribution plant.
