  • METHOD FOR DETECTING OPERATIONAL FAILURES
    Publication number: 20230195096
    Abstract: The present invention is related to the field of detection of operational failures, more specifically with the monitoring of head loss in equipment such as reactors, heat exchangers and adsorption vessels. The invention uses a method for continuous monitoring of equipment head loss, in order to assist in the early identification and action on this type of problem, avoiding or reducing losses resulting from its occurrence.

  • Integrated process for the manufacture of olefins and intermediates for the productions of ammonia and urea
    Patent number: 8932456
    Abstract: An integrated process for the manufacture of olefins and intermediates for the production of ammonia and urea, comprising an FCC reactor, a regenerator, a steam reforming unit, an air-separation unit, an ammonia production unit and a urea production unit, is described. This process makes it possible to minimize CO2 emissions to atmosphere, make use of heavy feedstocks of low added value (AR) for the production of light olefins, in addition to making maximum use of all the flows involved, thus increasing the energy efficiency achieved, all at the same time.

  • FLUID CATALYTIC CRACKING PROCESS WITH REDUCED CARBON DIOXIDE EMISSION
    Publication number: 20110155642
    Abstract: This invention concerns a fluid catalytic cracking (FCC) process with reduced carbon monoxide emission which modifies the regeneration phase of the spent catalyst by using pure oxygen without the need for dilution when burning coke adhering to the catalyst. In addition, this invention improves the reconditioning stage of the catalyst, incorporating a reconditioner supplementary to a conventional reconditioner which employs nitrogen as a carrier gas in the reconditioning of the already regenerated catalyst.
