Abstract

Tema ovog rada je dinamička simulacija procesa proizvodnje acetilena. Na početku rada su opisani osnovni tipovi postrojenja za proizvodnju acetilena, a zatim je, za proizvodnju od 50-250 m3/h acetilena, opisano niskotlačno acetilensko postrojenje i njegovi osnovni dijelovi.
Prema razrađenim matematičkim modelima razvijača acetilena, taložnika i bazena s procesnom vodom tijekom rada i mirovanja sustava, te bazena s procesnom vodom prilikom punjenja, izrađena je dinamička simulacija procesa tijekom 24 sata programom Simulink.
Analizom su obuhvaćeni:
• stacionarni rad cjelokupnog postrojenja pri maksimalnom proizvodnom kapacitetu od 250 m3/h
• utjecaj promjera cijevi na razinu vapnenog mlijeka u razvijaču acetilena
• utjecaj stanja zraka na temperature u taložniku i bazenu s procesnom vodom
• promjena proizvodnje acetilena s 80 m3/h na 180 m3/h
• realni slučaj doziranja kalcijevog karbida
• utjecaj prekida dovoda vode iz vodovoda na sustav
Za maksimalni proizvodni kapacitet, dimenzionirani su razvijač acetilena, taložnik i bazen s procesnom vodom.

Abstract (english)

The topic of this thesis is the dynamic simulation of the acetylene production process. At the beginning of the work are described the basic types of acetylene production plant, and then, for the production of 50-250 m3/ h of acetylene, a low-pressure acetylene plant and its basic parts are described.
According to elaborate mathematical models of the acetylene generator, sedimentation tank and pool with process water during operation and system rest, and pool with process water filling, a dynamic simulation of the process during 24 hours with the program Simulink was performed.
Analysis includes:
• stationary operation of the entire plant at maximum production capacity of 250 m3/h
• the impact of siphon pipe diameter to the level of milk lime in acetylene generator
• the impact of outdoor air on temperature in the tank and pool with process water
• change in acetylene production from 80 m3/h to 180 m3/h
• a real case of calcium carbide dosing
• the impact of interruption of water supply on the system
For maximum production capacity, an acetylene generator, sedimentation tank and pool with process water are dimensioned.
