The Resolve-T-procedure includes a combination of the distillation with solvents heavily polluted with solids (2.8. paint sludge) and the subsequent drying of the remaining solids.
The advantage is that a full yield of the organic solvent contained in the solid-solvent mixture is achieved without forming cracking products that might impair the recovered distillates through their colour or odour.
The purification of solvents involves the separation of solid and liquid substances. In the next step, a fractional distillation is carried out in which the solvents are separated from one another. Upon request, we can also be contracted to do this. Alternatively, we can market the acquired products for ourselves and consider this when billing our customers.
In this process, old coatings, old paints and paint coagulates, both water- and solvent-based, are processed. The substance mixtures are conditioned in the first process step by adding hydrophilic additives. Subsequently, in special drying units, sometimes under vacuum, the volatile constituents are distilled off in the form of solvents and water. All three fractions (solvent, water and dry matter) are returned to the economic cycle.
The Hydrosolve® process is used to prepare hydro-purging agents. These are used when painting with water-based systems, especially in the auto industry. In a first step, we separate the paint particles from the liquid components by adding special chemicals. The paint particles are filtered and then fed to the Isodry process. The water-solvent mixture is incorporated into products for surface treatment.
