INDUSTRIAL CLEANING SYSTEM INCLUDING VARIOUS TYPES OF SCALE REMOVAL SOLUTIONS AND COGNITIVE CLEANING Russian patent published in 2023 - IPC B08B3/08 F28G9/00 C23G1/00 

FIELD: heat exchange devices.

SUBSTANCE: method is used to clean the systems of heat exchange devices. This method is carried out using a computer system equipped with one or more processors and a memory device in which one or more programs are stored, allowing them to be executed by one or more processors. In the process of implementing this method, the percentage composition of the components of the cleaning solution is determined based on the technological parameters of the system of heat exchange devices. Process parameters include the chemical composition and operating temperature of the fluids passing through the heat exchanger system. The percentage composition of the cleaning solution is as follows: hydrogen peroxide - 2-90% (wt.), complexing agent - 3-30% (wt.), water-soluble calixarene - 0.01-10% (wt.) and water. The composition of the complexing agent includes a polybasic organic acid or its sodium salt or a derivative of phosphorous acid.

EFFECT: increasing the efficiency of the dissolving action when cleaning deposits of various nature with a simultaneous decrease in the aggressiveness of the solution in relation to the materials from which the equipment is made, the formation of a layer with high corrosion resistance on the surface.
