Claims (1)

  1. Загрузку сжиженных природных газов (СПГ) охлаждают путем первичного расширения в турбине, прямого теплообмена и вторичного статического расширения. Охлажденную загрузку фракционируют в колонне для удаления азота на газовую фазу, состоящую из азота и метана, выходящую из головной части колонны, и на лишенный азота поток СПГ, отводимый из основания вышеуказанной колонны. Из колонны отбирают первую фракцию и вторую фракцию СПГ, пропускают через теплообменник для охлаждения загрузки и затем снова инжектируют в колонну в качестве первой и второй ребойлерных фракций. После регенерации ее отрицательных калорий, газовую фракцию сжимают до получения потока горючего газа.
