Definitions

  • fluid coking One of the processes heretofore employed for the conversion of heavy feedstocks is the process known as fluid coking wherein the feedstock is sprayed, having been previously heated (if necessary) to facilitate spraying, into a bed of hot fluidized coke particles in a reactor.
  • fluid coking processes A brief description of fluid coking processes is given in Petroleum Refinery Engineering, 4th edition, by Nelson, pp. 689-691.
  • the feedstock is cracked into lighter products in the vapour phase and into coke, the coke being deposited on the coke particles of the fluidized bed.
  • the amount of particles in the bed 21 is determined by pressure transducers 29, 30 from which a differential pressure signal is derived by a differential pressure manometer 31.
  • a signal from the manometer 31 causes a control valve 32 to open progressively, thereby allowing an increase flow-rate of a propelling fluid from a line 33 to the main transfer line 34.
  • the propelling fluid is preferably steam, and it entrains, fiuidizes and propels particles along the smoothly curving transfer line 34 from near the base of the burner vessel 22 to the coking vessel 11, the particles entering near the top of the bed 12.
  • Control of temperature in the regenerator bed 40 is achieved by means of a temperature transducer 49 which acts on the controller 50 of a valve 51 in a steam propellant line 52.
  • a temperature transducer 49 acts on the controller 50 of a valve 51 in a steam propellant line 52.
  • the valve 51 is progressively opened, thereby increasing the rate of supply of particles from the relatively cooler bed 21 to the relatively hotter regenerator bed 40, thus reducing the temperature therein.
  • a method according to claim 1 in which the temperature in the second bed is sensed and diluent selected from nitrogen, water and steam is supplied to the second bed when the temperature in the second bed is in excess of a required temperature, the amount of diluent varying in accordance with the excess of the temperature relative to the required temperature.
