Abstract: The composition of the final mixture leaving a two-stage evaporator is controlled by measuring the boiling temperature of the intermediate liquid mixture which leaves the first-stage and which is in equilibrium with the vapor stream leaving the first-stage. From this boiling temperature, the concentration of the less volatile component is calculated, and this calculated concentration is used to adjust the heat input to the second stage in order to produce a final product having a predetermined composition.

Abstract: The flue gas scrubbing apparatus uses a scrubbing liquid containing alkaline earth compounds. To avoid troublesome encrustations, it is ensured that the solid particles arising with the formation of sulphur dioxide are prevented from precipitating for a prolonged period. The solid particles therefore circulate with the scrubbing liquid from the scrubbing liquid tank (11) to the spray device (25) and from there back again to the scrubbing liquid tank (11). The scrubbing apparatus has, in the scrubbing tank, a device (49) for whirling up solid particles. This device consists of a stirrer (53) which is fitted to a prolongation of the rotor of the submerged pump (21).

Abstract: Coating compositions based on ethylene vinyl acetate polymers have improved compatability with solvents (especially with aliphatic hydrocarbon solvents) hydrocarbon oils, and mineral waxes by blending the EVA with a fatty acid and heating at or above the melting point of the EVA. Furthermore the resultant blends are much more easily emulsified in the presence of cations that blends which have not been processed with the fatty acid. Typically the starting material for the improved product of this invention is a composition comprising a blend of an EVA polymer and a fatty acid which is miscible in all proportions with mineral spirits at 25°C or forms a solution at a level 5% of fatty acid in mineral spirits, such as coconut or palm fatty acids. Also disclosed is that the addition of a salt of an amine acetic acid in sufficient quantity to an acidified salt of zirconium (for example EDTA and zironium acetate) forms a novel emulsifying agent, and this emulsifying system is used advantageously with the described EVA/fatty acid blends.
