Hello guys,
I'm working on a plant which will be automated with pcs7 from siemens.
I have some trouble to define the plantstructure according to IS88.
The plant is recycling bottlecaps under pyrolyse conditions.
There are a lot of processes at the plant:
1) supply of bottlecaps into a container and from there will be blowen into silo's.
2) bottlecaps will be transported from the silo's to a drum which has burners which heat the drum
3) after the drum, the bottlecaps that come out of the drum will be transported to another drum by air.
4) The bottlecaps which come out of the drum will be transported by vibration to a press.
5) bottlecaps will be pressed together
6) gastreatment is also available to purify the outgoing gasses from the drums
7) gasses will go to a analyzer
8)gasses will go to a chimney
I don't know excactly to design the proces according to ISA88.
My definition is as follows:
Process cell: The complete process from supply of bottlecaps to the press (begin to end), so all the units and equipment modules of the proces.
Unit: Individual processes, so the 1st drum is a unit, the second drum is a unit, gastreatment is a unit, and so on
Equipment module: the individual processes in a unit, for example the unit: Drum: rotate drum, burner management system, transportation of bottlecaps, supply of demiwater, suply of compressed air etc.
Control modules: valves, motors etc.
Is this correct?
Thank you,
Grtz Sandor
