| Gaia: | Title screen Gas hydrate plugs are a serious problem in the operation of oil and gas pipelines. Existing methods for removing hydrate plugs are resource-consuming, unsafe and difficult to implement. This paper focused on methane hydrate dissociation by water, steam, and air injection into a pipeline. Additional experiments were performed to study hydrate blockage remediation by a heating cable system and by chemical inhibition. It was found that the rate of hydrate plug removal when using a water flow is approximately 1.4 times higher than with a steam flow, 11 times higher than with an air flow, 12 times higher than with methanol injection, and more then 200 times higher than with a heating cable. The experimental findings and patterns were generalized using dimensionless complexes to obtain unified mathematical expressions. These expressions can predict the effective conditions of heat and mass transfer to accelerate hydrate dissociation. Using multi-criteria analysis in terms of energy and economic efficiency, we propose recommendations and conceptual technological solutions to minimize the detrimental effect of hydrate plugging on oil and gas flow. Using an appropriate integrated approach, the conditions for the rational use of both individual and combined thermal stimulation techniques were determined Текстовый файл AM_Agreement |
