| titleOfInvention | How to remove dirt from heat exchanger |
| abstract | (57) [Problem] A substance that does not hinder the process inside a heat exchanger while continuing the operation of a heating type heat exchanger in which a dirt component based on heavy substances adheres to the inside and the heat exchange capacity is reduced. By introducing a vapor or a substance which becomes a vapor inside the heat exchanger to remove dirt, it is possible to remove dirt components and restore the heat exchange ability. By this method, there is provided a method for removing dirt from a heat exchanger, which does not adversely affect the stable operation of a plant due to the stoppage of the heat exchanger and does not cause a problem such as ensuring safety in removing the dirt from the heat exchanger. In a process of a chemical plant for separating and purifying a target substance from a liquid containing a target substance and a heavy substance by distillation, the liquid containing the target substance and the heavy substance adheres inside a heat exchanger for heating and evaporating the liquid containing the heavy substance. To remove dirt based on a substance by introducing a vapor of a substance that does not hinder the above-mentioned process or a substance that becomes a vapor inside the heat exchanger into the heat exchanger while continuing operation of the heat exchanger. A method for removing dirt from a heat exchanger. |
