Abstract

Described herein is a production system including a unit, wherein the unit includes a subunit (1.1) for continuous manufacture of formulations. The subunit includes a combination of a small-volume process mixer and a buffer tank, means of feeding defined amounts of feedstocks into the process mixer, a measurement unit for ascertaining properties of a formulation manufactured in the process mixer, an evaluation unit for determining a deviation of properties of the formulation manufactured in the process mixer from the properties of a predefined target state, and a unit for adjusting the feed of feedstocks in view of the deviations. Also described herein is a process for manufacturing formulations.

First claim

The invention claimed is:

1. A process for continuously manufacturing formulations, the process comprising:
continuously feeding feedstocks into a process mixer (kP) in which there is a first mixing device for mixing of the feedstocks,
continuously manufacturing a formulation by mixing the feedstocks in the process mixer (kP) and transferring the formulation into a buffer tank with a second mixing device via a connection between the process mixer (kP) and the buffer tank,
ascertaining properties of the continuously manufactured formulation by means of a measurement unit, the measurement unit being assigned to the connection of process mixer and buffer tank or arranged within a corresponding conduit system,
determining a deviation of properties from a predetermined desired state in a predictive state of the overall batch of the formulation based on the properties of the continuously manufactured formulation by means of an evaluation unit,
ascertaining adjustment volumes for feedstocks that are needed in view of the deviations in the properties of the continuously manufactured formulation from the target state of the overall batch and a total volume of formulation volume to be manufactured for establishment of a target state of the total volume,
continuously manufacturing further portions of the formulation in the process mixer (kP), taking account of the adjustment volumes ascertained by adjusting the feed of feedstocks into the process mixer (kP), and
combining the manufactured portions for manufacture of the total volume.

2. The process as claimed in claim 1 , wherein the formulations are manufactured using liquid feedstocks and feedstocks that can be used as liquid feedstocks through pretreatment.

3. The process as claimed in claim 2 , wherein the formulations are manufactured with exclusive use of liquid feedstocks and feedstocks that can be used as liquid feedstocks through pretreatment.

4. The process as claimed in claim 1 , wherein the continuous feeding of feedstocks is effected using means (M), where the means (M) have devices for withdrawing defined amounts of feedstocks from reservoirs that incorporate technical means of monitoring and closed-loop control of a mass flow rate of the respective feedstocks.

5. The process as claimed in claim 4 , wherein the means (M) additionally comprise fluid-conducting pipework systems for transfer of the defined amounts of feedstocks into the process mixer.

6. The process as claimed in claim 1 , wherein the properties that are ascertained in the measurement unit include viscosity, pH, color, conductivity, density, and/or temperature.

7. The process as claimed in claim 1 , wherein the adjustment of the feeding of feedstocks is set up such that, after the manufacture of an overall batch, the overall batch has a target state predefined by reference values.

8. The process as claimed in claim 1 , wherein the continuous feeding of defined amounts of feedstocks into the process mixer (kP) comprises the direct feeding of intermediates which have been manufactured in a subunit.
