Abstract: An insect-repellent and/or insecticidal product is described obtained by concentration of by-product vegetable water from olive milling, characterized in that it has a dry matter content of 10% or higher and a pH of 5 or higher; a method for the preparation of such a product is also described comprising the step of making a continuous stream of said vegetable water flow in the state of a turbulent thin layer, in contact with a heated wall of a turbo-concentrator comprising a horizontal-axis cylindrical tubular body (1), having an inlet opening (5) for said vegetable water and a final product discharge opening (7), a heating jacket (4) to bring the inner wall of said tubular body at a pre-determined temperature, and a bladed rotor (8), rotatably supported in the cylindrical body (1).

Abstract: A method for causing or facilitating the flow of dispersions of solid particulates in liquids, having characteristics of high viscosity or resistance to flow, with particular reference to sludges from purification plants of civil or industrial wastes, which method comprises the addition to the dispersions of silicones of formula wherein R and R? are identical or different and represent a radical chosen between C1-C5 alkyl and aryl; x is an integer comprised between 3 and 2000.

Abstract: A method for producing powder paints which comprises the steps of: a) preparing a paste comprising at least one thermosetting plastic resin, at least one curing agent, at least one pigment and water and making the paste flow in the form of a thin layer and under conditions of high turbulence in contact with a wall at a predetermined temperature; b) drying the paste by making it flow into a thin and turbulent layer in contact with a heated wall and optionally with a flow of heated gas.

Abstract: A process for the fractional distillation of crude oil, which comprises the steps of: feeding a continuous current of crude oil at 310-400° C. into a turbomixer comprising a tubular cylindrical body (1) provided with a rotor (9) formed with helically oriented paddles (10) and rotatably supported inside the body, along with a continuous current of steam; subjecting both currents to the mechanical action of the paddled rotor (9), so as to create a thin tubular dynamic turbulent layer, which is discharged and fed continuously into a fractioning column, at a predetermined height level in the column, to produce an upward-flowing vapor current and a downward-flowing liquid current therein; and optionally discharging the downward-flowing liquid current continuously from the column bottom, and feeding it continuously into the turbomixer in the same direction as the crude oil current.

Abstract: A method of remediating soil that contains heavy metals comprises the steps of removing and sieving heavy metal-containing soil to separate stones and gravel, and treating the sieved soil, in a thin layer kept in a strongly turbulent state, with a solution of an alkali sulfide at a temperature of at least 50° C.

Abstract: A method for producing powder paints which comprises the steps of:

Abstract: Dry master batch comprising at least one pigment and a dispersion carrier, characterized in that it contains at least 80% by weight calculated on the weight of the mixture of particles of pigment dispersed in said carrier; it can be prepared by means of a process that comprises the steps of feeding a flow of pigment obtained from a process of synthesis in aqueous or organic phase in the form of a filter pressed, tape pressed or centrifuged wet cake and a flow of a solution of a dispersant carrier in a turbo-mixer, centrifuging such flows against the inner wall of said turbo-mixer, with the formation of a dye paste arranged in a thin and dynamic layer; drying the dye paste obtaining said dry master batch, which is particularly suited for the preparation of inks and paints or for the pigmentation of plastic materials.

Abstract: A method of remediating soil that contains heavy metals comprises the steps of removing and sieving heavy metal-containing soil to separate stones and gravel, and treating the sieved soil, in a thin layer kept in a strongly turbulent state, with a solution of an alkali sulfide at a temperature of at least 50° C.

Abstract: A method of producing elastomers or elastomeric mixtures, in which independent flows of N.sub.2, of a solution of elastomers in organic solvents and, possibly, of forming and nucleation additives, are processed mechanically and thermally in a turbo-drier so as to produce elastomers or elastomeric mixtures, respectively, in solvent-free, granulated form.
