Využití řídícího systému při zpracování a expedici CO2

Abstract

In my Thesis I am pointing at usage of PLC technics (Siemens S7) by process, storage and expedition of liquid CO2. Particulary it means centre of Linde Gas a.s. company based in Litvínov. I am focusing on this 3 main parts: Types of PLC, communication between each PLCs, usage of visulation SW (IFix) and types of I/O signals. Usage of regulation circuits while processing into liquid CO2, in which I designed cascade regulator for controling performance of compressors. This cascade regulator should lead to electric energy saving and increase of production, because performance of compressors will react in automatic to change pressure and amount CO2 on input Subscription of the cartank loading sequence – I made CPM diagram and Gant diagram, which should produce time reserve of.
