The "color_gs" project
Introduction
After a brief overview of PCS 7 SMART (Page 21), you can start creating the color_gs project.
Additional theoretical knowledge is required to understand these instructions. Hence, each
topic is provided with some background information.
Plant description
Only a small part of the entire plant will be configured for automatic dye production since
configuring the entire plant will be out of scope for this Getting Started project. This minimal
plant configuration will be integrated with the entire plant to understand the overall context in
a better way.
The individual phases of the production process are:
Phase I - Raw Materials
The liquid raw materials for the product are stored in two raw material tanks and are pumped
from these tanks to the reactors.
The solid raw materials are stored in three silos. Screw conveyors are used to measure out
the solid raw materials from the silos to a weigh hopper for weighing. Another screw conveyor
and a blower are used to blow the raw materials into one of the two mixing tanks in the correct
mixing ratio.
Phase II – Production
The required quantities of liquid material are fed from the two raw material tanks to Reactor 1
or Reactor 2 by means of valves. The solid materials from the mixing containers are transported
via screw conveyors to the reactors where they are blended using an agitator. The product is
produced in the reactors by agitating, heating and cooling the raw materials together with the
additives. Valves and actuators control the temperature in the reactors. If required, water from
a filtration plant can be introduced into the reactors using a flow controller.
Phase III - Holding Phase
The product is pumped to a holding tank for post processing. Here, it is stirred slowly and kept
at a constant temperature.
