    摘要： In a method and an apparatus for cleaning tar-bearing waste water (17), a mixture of water and hydrocarbons, e.g. comprising polyaromatic hydrocarbons and phenols, the mixture is separated into a low-boiling-point part and a high-boiling-point part, bringing the low-boiling-point part on vapour form in a boiler (1), and the low-boiling-point part is cracked in vapour form at a high temperature in a reactor (2), providing light combustible gases, which can be utilised in e.g. gas engines, gas turbines or the like. Furthermore, the high-boiling-point part may be used for energy supply to the process or other processes or as an alternative be cracked for providing light combustible gases.

    摘要： A process for treating a solid-liquid mixture by cavitation has been developed to decompose at least some contaminant associated with the solid particles, the contaminant either being adsorbed into the pores of the solid or onto the surface of the solid particles. The process includes the step of subjecting the mixture to cavitation such that a portion of the contaminant is chemically decomposed. Typically the chemical decomposition occurs at the surface of the solid particles, although the process can also occur to some extent within the pores near the surface of the solid material being treated. Typically the cavitation process is an ultrasonic treatment step, although other cavitation processes are applicable, for example high shear mixing. The cavitation effect is capable of achieving physico-chemical changes at the particle surfaces. The localised high temperatures on bubble collapse (as high as 5000K) can decompose contaminant substances such as PCB and other hazardous materials including polybrominated biphenyl (PBB), organochloride and organophosphate compounds, pesticides and the like. One of the advantages of the treatment process is that the decomposition products are quenched quickly to the temperature of the bulk fluid (at, for example, 50oC) which avoids the reformation of the PCB or the formation of undesirable side reaction products such as dioxins.

    摘要： A process for extracting from aqueous solution the alkali metal or ammonium salt of a phenol, naphthol, anthrol or phenanthrol or the corresponding thiol, which comprises contacting an aqueous alkaline or neutral solution of the alkali metal or ammonium salt, in which is dissolved an alkali metal or ammonium fluoride, chloride, bromide, hydroxide, nitrate, nitrite, sulphate, sulphite, sulphide, thiosulphate, phosphate, hydrogen phosphate, carbonate, bicarbonate, cyanate, cyanide, thiocyanate, borate, chlorate, chlorite, hypochlorite, perchlorate, chromate, dichromate or permanganate, with a partially water-miscible organic solvent so as to transfer aqueous solution of the alkali metal or ammonium salt of the phenol, naphthol, anthrol or phenanthrol or corresponding thiol into the solvent while retaining separate aqueous and solvent phases, and thereafter separating the solvent phase containing the alkali metal or ammonium salt and water from the aqueous phase, the ratio of solvent to water in the separated solvent phase being from 0.5:1 to 10:1 w/w.
