AN ENERGY-EFFICIENT APPROACH TO GAS HEATING AND ACCOUNTING IN STATIONARY HYDRAULIC FRACTURING SYSTEMS OF THE GAS SUPPLY SYSTEM OF UKRAINE

A gas regulating point (GRP) is a complex of equipment for reducing gas pressure and maintaining it at a given level. In the fracturing room, for the productive operation of the regulators, the optimum temperature must be maintained, in the winter period at least +5℃. At the same time, it is necessary to take into account the fact that when throttling natural gas, its temperature decreases. The presence of moisture in the gases significantly complicates the operation of the gas pipeline. Vapors of hydrocarbons, which are part of the gas, at certain (negative) temperatures turn into liquid, i.e. form condensate. Accordingly, the water vapor in the gas turns into a liquid, and then into ice. By itself, gas condensate can clog gas pipelines, valves of pressure regulators, shut-off fittings, get into impulse tubes, which will lead the regulator out of normal operation. maintenance solutions The existing means of maintaining the required temperature in the hydraulic fracturing room have certain disadvantages. Burning gas in the fracturing room is dangerous, as well as additional financial costs. This is particularly noticeable in recent times when the cost of gas on the European market is increasing, so it is advisable to take measures to reduce gas consumption on the way of its transportation. With certain changes in the hydraulic fracturing principle, the traditional heating of the entire hydraulic fracturing room can be replaced by heating only the transported gas. For this, it is suggested to install a heater that works according to the Rank-Hilsch principle. Replacing traditional boilers in hydraulic fracturing with heaters installed directly on the gas pipeline solves several issues: saving energy, fire safety, lack of environmental impact. The use of the Rank-Hilsch effect will ensure optimal operating conditions of the pressure regulator and stable gas supply conditions without complete heating of the room. The proposed conversion allows to receive gas consumption data at different time intervals, both in metric and energy units, and transmit them through the supplier-consumer network
