Abstract
A method for the production of an industrial diluent which includes the steps of heating a liquid waste from a facility that manufactures coatings, inks, lacquers, adhesives, or dyes in a mixer-reactor to generate a vapor, flowing the vapor into a distillation column, distilling the vapor to form distillation components, and transferring each component to a tank designated for such component. The method may include the additional steps of mixing at least two of the components in a predetermined amount, and thoroughly mixing the liquid waste during the heating step. The heating step is preferably effected by applying heat substantially uniformly to the liquid waste.

A method for the recovery of solvents from a liquid solvent waste from a facility that manufactures coatings, ink, lacquer, adhesive or dyes, the recovered solvents being suitable for mixing to produce an industrial diluent, comprising the steps of:
- heating the liquid solvent waste in a mixer-reactor to generate a vapor;
- flowing the vapor into a distillation column;
- distilling the vapor to form distillation components;
- and
- transferring each component to a separate tank which is designated for such component, the separate components being the recovered solvents.
A method for the production of an industrial diluent, comprising the steps of:
- heating a liquid solvent waste from a facility that manufactures coatings, ink, lacquer, adhesive or dyes in a mixer-reactor to generate a vapor;
- flowing the vapor into a distillation column;
- distilling the vapor to form distillation components;
- transferring each component to a separate tank which is designated for such component;
- and
- mixing at least two of the components in a predetermined amount to produce the industrial diluent.
A process for the production of industrial diluents, comprising the steps of:
- heating a liquid solvent waste in a vessel to generate a vapor, the liquid solvent waste being waste from a coating, an ink, a lacquer, an adhesive or a dyeing industry;
- flowing the vapor into a fractionating column;
- condensing the vapor many times along the fractionating column;
- finally condensing the vapor in a condenser to form separate distillates;
- recovering the separate distillates in separate tanks which are connected to a mixing tank;
- flowing distillates from the separate tanks to the mixing tank;
- and
- mixing the distillates in the mixing tank to produce the diluents.
A process for the recovery of solvents from a liquid solvent waste that contains the solvent to be recovered and which is a liquid waste effluent from a coating, an ink, a lacquer, an adhesive or a dyeing industry, the recovered solvents being suitable for blending to produce diluents, comprising the steps of:
- heating the liquid waste in a vessel to generate a vapor;
- flowing the vapor into a fractionating column;
- condensing the vapor many times along the fractionating column;
- finally condensing the vapor in a condenser to form separate distillates;
- and
- recovering the separate distillates in separate tanks, the separate distillates being the recovered solvents.
