Abstract

The object of research is the heat and mass transfer processes that occur on the surface of a gas hydrate granule moving in a gas pipeline.

The research solved the problem of the oil and gas industry – the fight against the formation of gas hydrates (GH) in hydrocarbon production and transportation systems. A promising approach to the intensification of hydrate dissociation by using microwave electromagnetic radiation is proposed. The features of the results obtained consist in the development of a mathematical model that combines two processes of synthesis and dissociation of gas hydrates, taking into account hydrodynamic processes in the pipeline. The main differences of the proposed mathematical model are: simultaneous consideration of two mutually opposing processes of synthesis and dissociation of gas hydrate on the surface of the granule; these processes occur during the movement of the gas hydrate granule inside the gas pipeline; heating of the gas hydrate granule occurs as a result of its absorption of direct and reflected multimode microwave electromagnetic radiation.

A complex approximation dependence was obtained for determining the required emitter power Pw = 124Cgh/R1.7, which allows one to quickly calculate the required minimum magnetron power to combat hydrate formation.

It was established that for the destruction of small particles (<0.01 mm) even if their concentration is low (0.01–0.02%), a relatively high-power emitter (3–5 kW) is required. The same was observed in the case of GH accumulation to high concentrations (>0.1%) with particle sizes of 0.05–0.1 mm. Therefore, the most advantageous strategy for combating GH accumulation is its active destruction when it reaches sizes of 0.02–0.05 mm, which do not harm the course of the main technological process.

The obtained dependences are the basis for improving gas preparation technologies under hydrate formation conditions by using microwave radiation energy.
