  • Patent number: 5424043
    Abstract: A device for treating gaseous effluents from a catalytic cracking unit comprises at least one first stage for regenerating a catalyst used in a catalytic cracking process wherein the gaseous effluents issuing from a cracking catalyst regenerator are treated in a heat recovery unit (CR) including a treating chamber having an entrained bed. The absorbent introduced in this chamber has a "fine" grain size ranging between 0.1 and 100 .mu.m and can be regenerated in the device downstream from heat recovery unit (CR).
    Type: Grant
    Filed: January 27, 1994
    Date of Patent: June 13, 1995
    Assignee: Institut Francais du Petrole and Babcock Enterprise
    Inventors: Gerard Martin, Jean-Louis Bouju
  • Patent number: 5328674
    Abstract: Process for desulfurizing combustion gas wherein the gas is fractionated into at least two flows which pass through distinct passageways (4 and 5) and receive particles of a solid desulfurizing agent coming from distinct injectors (7 and 8) . The two particle-charged flows meet (9) , are separated again (10 and 11) and meet again thereafter (12). The process can be repeated several times. The final mixture is carried off and fractionated into desulfurized gas and recovered solid particles.

  • Patent number: 5230871
    Abstract: For generating heat, with reduced emission of sulphur and nitrogen oxides, a fuel containing sulphur oxides and nitrogen is effected, the combustion burned and particles of a fresh absorbent are fed into a turbulent zone (9) upstream of an adiabatic desulphurisation zone (8); and the mixture produced is passed into a heat recovery zone (16). Part of the absorbent is recycled to the desulphurisation zone, and the flow rate of fresh absorbent and recycled absorbent is adjusted so that the temperature of that zone is from to C.
