Abstract

Изобретение предлагает способ защиты трубопровода для углеводородов в течение периода уменьшенного углеводородного потока; указанный способ включает введение азота в указанный трубопровод в течение указанного периода при давлении р от 1 до 350 бар изб. (от 0,1 до 35 МПа изб.) и со скоростью от 1,5∙А до 35∙А кг/с (где А представляет собой площадь внутреннего поперечного сечения трубопровода в кв. метрах) на период t часов, при этом t = (p∙d)/n, где d представляет собой протяженность трубопровода в км от места введения азота, а n представляет собой число от 10 до 400.
