Abrégé

The invention relates to a method for cleaning equipment with a hollow sealed circuit and can be used in industry for cleaning equipment from salt measures, oil deposits, including asphalt paraffin, tar deposits and biological deposits. The claimed method of cleaning the inner surface of the equipment with a hollow sealed circuit consists in pumping a washing solution through an internal cavity of the said circuit with an unsteady flow regime created by local stops of the washing solution flow at the moment of oxygen or carbon dioxide gas formation, characterized by an intensity at which the pressure in the gas bubble moments of time, namely when the bubble grows, exceeds the pressure of the wash solution. The embodiment of the claimed method allows, while maintaining the cleaning efficiency, to significantly simplify its implementation and further expand the scope of use.

A method is used for cleaning heat exchanger systems. The method is performed at a computer system having one or more processors and memory storing one or more programs configured for execution by the one or more processors. The method determines component percentages of a cleaning solution based, at least in part, on operational parameters of a heat exchanger system. The operational parameters include chemical composition of fluids passing through the heat exchanger system and operating temperatures of the fluids passing through the heat exchanger system. The component percentages of the cleaning solution include: (1) hydrogen peroxide. 2-90 wt. %: (2) a complexing agent. 3-30 wt. %: (3) water-soluble calixarene. 0.01-10 wt. %; and (4) water. The complexing agent includes a polybasic organic acid or a sodium salt thereof, or a derivative of phosphorous acid.

Abrégé

A method is performed at a computer system to clean heat exchanger systems. The system estimates the fouling level of a heat exchanger system based on measured performance parameters of the heat exchanger system. The performance parameters include the rate of heat exchange. The system generates a system performance cost model based on the estimated fouling level of the heat exchanger system. The system also determines an initial cleaning recipe based on operational parameters of the heat exchanger system. The operational parameters include chemical composition and operating temperatures of fluids passing through the heat exchanger system. The system generates a cleaning cost model based on the initial cleaning recipe and calculates a cleaning schedule to minimize overall operational cost using both the system performance cost model and the cleaning cost model. The system then executes the initial cleaning recipe at the heat exchanger system according to the calculated cleaning schedule.
