CALCULATION OF PROPANE THERMAL CRACKING PROCESS PARAMETERS

Thermal and one many thermocatalytic processes high temperature conditions is going This consider taking raw material first tubular in ovens certain up to heated. Some the same as furnace at time replace reactor doing In oven placed serpentine of pipes beginning part it heats up. Next cracking process goes. Raw whom individual hydrocarbons use when done unconverted live reaction environment give too favorable. Catalytic isomerization 50-65% isopentane from normal pentane taken. 1-2% gas during doesn't buy N- pentanm non-isomerizable again returned according reaches 97-98%. According prepared model, final indicator output target products (propylene + ethylene) these components relative total filling were taken optimality criteria study. The essence recirculation method that mixture reacting non-reacting enters separator system after reactor. Here they are separated each other, then unreacted mixed with fresh materials fed back into our case, only propane ethane given recirculation, not all Because converted intended - propylene by primary reactions. if a devices included complex account mathematical modeling optimization process, obtained value criterion will be wrong. can change optimal criterion. systems mentioned processes, separating node main conditions. A usually consists reactors, separators other associated units. An inversely related carried out continuous between steps input previous subsequent step. It seems clear considering kinetics simultaneously sufficient. To obtain realistic results, necessary above equations together place separator.In this work, results study preparation theoretical regularities adsorption-separation junctions recirculated chemical-technological complexes their practical shown. During modeling, along nodes complex, attention was paid adsorption additions German practice. Keywords: propane, cracking, n-pentane, isopentane, methane, hydrogen, hydrocarbon.
