Abstract: 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.

Abstract: The invention relates to the field of removing various types of deposits from a surface, preferably the surface of industrial equipment. A removing deposits from a surface comprises the steps of applying a first precursor mix to the surface; allowing the first precursor mix to pass through the deposits; removing the first precursor mix; applying a second precursor mix to the surface; allowing the second precursor mix to pass though the deposits; removing the second precursor mix; wherein the first precursor mix reacts with the second precursor mix to produce a foam, and the foam expands inside pores and cracks of the deposits, and results in breaking the deposit from the surface.

Abstract: Cleaning processing equipment may include generating a function characterizing a relationship between fouling formation in the processing equipment and operation of the processing equipment. A cleaning recipe may be selected based on properties of fouling material formed in the processing equipment during operation of the processing equipment. Operating costs associated with cleaning schedules may be determined based on the first function and the cleaning recipe and one of the cleaning schedules may be selected based on the respective determined operating costs. A cleaning process on the processing equipment may be executed according to the selected cleaning schedule using the selected cleaning recipe.
