PHASE TRANSFORMATIONS IN GAS TRANSPORT IN PIPELINES AND METHODS TO ELIMINATE THE PROBLEMS ARISING

Abstract

One of the actual problems of the exploitation and production companies of the oil and gas industry is liquid accumulation and hydrate formation in the gas production and transportation systems in the pipelines, as well as the elimination of the complications caused by them. The methods for preventing the complications arising in the gas collection and transportation systems, related to the processes of heat exchange of the pipeline with the environment, changes in the thermobaric conditions during the flow, phase transitions between gas and liquid have been investigated existing methods. In the course of studies, taking into account the complex impact of processes occurring during the operation of gas pipelines, barodynamic factors affecting hydrate formation and the component composition of the gas were evaluated. A specially developed technological solution was proposed to eliminate accumulations formed in the gas pipeline.
