标题：Justification of Gas Supply System based on Tank Units with NaturalRegasification of Liquefied Hydrocarbon Gas, PreventingFormation of Hydrates in Pressure Controllers
摘要：Justification of gas supply system is given which prevents formation of crystalline hydrates inpressure controllers during operation of tank units with natural regasification of Liquefied Hydrocarbon Gas(LHG). Processes of heat exchange between gas supply system and ambiance are reviewed and their operatingtemperature conditions are determined. Prerequisites are formed to determine optimum thickness of thermalinsulation of gas supply system elements which allows to ensure maintenance of superheat of vapor phase ofliquefied hydrocarbon gas upstream pressure controller and avoid hydrate formation.
