Abstract

The report deals with the authors method of gas transportation in permafrost zone with ecologically safe of natural geosystem in permafrost areas. These problems are addressed through optimization of processes of mass and energy exchange between pipeline and surrounding medium under maximum reduction of investment costs and simplification of gas treatment before transportation. 1 Introduction The main task of our investigations is to ensure accident-free operation of oil and gas transport units, safety of people. A chilled gas pipelining experiment has been performed on a test site of an operating gas pipeline. In the course of the experiment we have received data on the freezing peculiarities of different soils in the gas pipeline base. The freezing rate was found to be 0.5 to 1.6 mm/hour and that of the pipeline displacement 45-65 m
