Abstract: PROBLEM TO BE SOLVED: To provide a satisfactory process order even when an order of manufacturing plan is collapsed. SOLUTION: This manufacturing control method is executed according to the manufacturing plan and in the manufacturing control method of separable chemical processes to be used for manufacturing plural generated products A, B, C at a plurality of stages 1, 2, 3, a measured value based on an operation parameter at least one stage of the stages 1, 2, 3 is recorded, monitored, a signal is generated when the measured value exceeds a limit value, the manufacturing plan is calculated again, based on the signal and the processes, are executed, based on a new manufacturing plan of the stages 1, 2, 3.

Abstract: PROBLEM TO BE SOLVED: To shorten cooling time of a dispersion or a liq. after deodorizing treatment, to prevent a film which brings adhesion, piling and/or clogging of an apparatus during cooling treatment from being formed in case of a polymer- contg. dispersion and to simplify simultaneously a complicated structure of the apparatus. SOLUTION: Steam is passed through a dispersion or a liq. to be cooled and held in a treating container 1 and the dispersion or the liq. is whipped as the result (a) and this air bubble is discharged from the top part of the treating container 1 and it is fed into a vacuum separating container 4 through a nozzle and the air bubble is exploded during it (b) and steam formed from the air bubble is condensed by means of a heat exchanger 3 and volatile org. components are simultaneously removed (c) and exploded air bubble is returned to the container (d) and the processes (a) to (d) are performed until the dispersion or the liq. is deodorized to a required extent.

Abstract: Post-polymerisation reduction of the residual monomer content of a liquid solution, mixture, melt, suspension or dispersion obtained by free radical polymerisation is effected by adding a redox initiator system at a suitable temperature, the liquid in the reactor being mixed for the least possible time and at least one of the components of the initiator being added gradually to the liquid for a dose time which is 10-250 times the mixing time of the liquid.

Abstract: Thermal cleaning of articles that come into contact with polymer dispersions comprises treatment in a sand fluidised bed at a temperature high enough to pyrolyse and/or vaporise the contaminants produced by the polymer dispersions. Also claimed is the use of a sand fluidised bed for cleaning these articles.

Abstract: A method for cooling dispersions or liquids (D/L) after a deodorising process comprising (a) passing steam through the D/L in a boiler (1), causing it to foam, (b) taking the foam from the top of the boiler into an evacuated separator (4) through a jet (5) and thus breaking the foam, (c) condensing the water vapour from the foam in a heat exchanger (8) and removing organic volatiles, and (d) returning the broken foam to (1). This process is continued until the D/L is deodorised to the required extent, then the hot D/L is cooled by transferring it from the bottom of (1) to the evacuated separator (4) via jet (5), the water vapour produced is condensed in (8) as before, and the cooled D/L is taken off at the bottom of (4).

Abstract: The use of one- or multi-stage stirrer(s), which produce axial as well as tangential flow components, in a reactor for polymer production by heterophase polymerisation is claimed.
