Abstract

Изобретение относится к способу удаления парафина, отложившегося на поверхности стенки, находящейся в контакте с потоком текучей среды, содержащему охлаждение стенки и потока текучей среды до температуры ниже температуры появления парафина, что должно обеспечивать осаждение растворенного парафина на поверхности стенки, при этом способ дополнительно содержит нагрев стенки на короткий период времени для высвобождения отложившегося парафина с поверхности стенки, в основном, в форме твердых фрагментов. Дополнительно, изобретение относится к способу определения толщины отложения парафина в секции трубы посредством вычисления по температурам, полученным выше по потоку и ниже по потоку в упомянутой секции трубы, до и после приложения теплового импульса.
