Optimization of depropanizer operation for cracking unit with HYSYS analogue system;

The techniques of SC-1 type cracking heater,predepropanization unit,prehydrogenation separation element,opening heat pump were used in new 450kt/a ethylene equipment of Lanzhou Petrochemical Company.

Dynamic simulation and optimization of fixed-bed reactor for propane dehydrogenation

Modeling of coke burning-off regeneration for coked propane dehydrogenation catalyst

The production of propylene by propane dehydrogenation has become the third source of propylene to meet the continuously increasing demand of propylene and its derivatives in the world.

Study on coupling of dehydrogenation of propane with reversed water-gas shift reaction for propylene synthesis;

Higher productivity and selectivity of propene in dehydrogenation of propane wereachieved with MgO crystal catalyst treated by shock wave.

Aiming at the serious fouling happened in the depropanizer reboiler of ethylene plant, a high effective antifoulant, RIPP1461, was developed and used in the depropanizer of the 300 kt/a ethylene plant at Maoming Petrochemical Co.

ommercial　tests　of　RIPP1402　antifoulant　were　carried　out　in　depropanizer　and　reboilers　of　Qilu　30×104t/a　ethylene　plant.

The object we discussed in this article is 12 MTA gas fractionation depropanizer.
