Method and device for judging inner leakage of high-pressure heat exchanger, medium and electronic equipment

The invention relates to a method and a device for judging inner leakage of a high-pressure heat exchanger, a medium and electronic equipment, and the method comprises the following steps: cutting distillate oil treated by the high-pressure heat exchanger in a hydrodesulfurization device into a preset number of distillate substances according to a preset distillation range; determining the sulfur content of each fraction substance, and determining an internal leakage parameter according to the sulfur content of each fraction substance and the total sulfur content of the distillate oil; and if the inner leakage parameter is smaller than a preset threshold value, it is determined that inner leakage exists in the high-pressure heat exchanger. The process for judging the inner leakage of the high-pressure heat exchanger is simple, the operability is high, the cost is low, and whether the high-pressure heat exchanger has trace inner leakage or not can be judged more accurately. 本公开涉及一种高压换热器内漏的判断方法、装置、介质及电子设备，该方法包括
