Definitions

  • This invention relates generally to a continuous process for the preparation of a mixture of carbon, monoxide and hydrogen gases.
  • a melter-gasifier is used in which fossil fuel and oxygen, as well as steam and lime or limestone, are fed to a pressurized molten metal bath to produce the mixture of carbon monoxide and hydrogen gases.
  • melter-gasifiers for effecting the partial combustion of the carbon content of fossil fuels in a molten metal bath to produce a gaseous mixture largely composed of hydrogen and carbon monoxide are well known in the art. Such melter-gasifiers are shown, for example, in U.S. Patents Nos. 3,533,739; 3,526,478 and 4,062,657.
  • melter-gasifier More recently it has been recognized that improved efficiency can be achieved in the operation of such a melter-gasifier if the conversion of the carbonaceous fossil fuel is carried out in a pressurized reaction system. However, if a pressurized system is used, the removal from the melter-gasifier of molten slag accumulating on the surface of the molten bath presents a problem. If the operation of the melter-gasifier is interrupted periodically to permit batchwise removal of the molten slag, there will be a discontinuous flow of product gases from the system.
  • shut-off valves at the top and bottom of the lock hopper which must maintain a tight seal on the pressurized systems, are exposed to a flood of water as the mixture of slag and water enters the hopper and is discharged therefrom. This water tends to wash away lubricants on the valve parts and to corrode them. Also large amounts of cooling water are used because the lock hopper is flooded and discharged during each operating cycle.
  • the objects and advantages of the present method are achieved in general by providing a system wherein the molten slag is continuously withdrawn from the melter- gasifier and delivered to a body of cooling water in a quenching chamber as described above, but the solidified slag is de-watered before being removed from the pressurized system through a pressure lock. As described below, the quantity of water used can be minimized by withdrawing quench water from the quench chamber and cooling and re-circulating it.
  • the numeral 10 designates a melter-gasifier reactor of conventional construction containing a molten iron bath 12 with a layer of slag 14 floating thereon.
  • a feed tube assembly 16 comprising an inner tube 18 and an outer tube 20.
  • a mixture of steam and oxygen from a suitable source is fed to the reactor through tube 18 and a mixture of powdered coal and limestone is fed through the tube 20.
  • Partial combustion of the coal in the presence of steam at the discharge ends of the tubes provides heat to maintain bath 12 and slag layer 14 molten and produces a gaseous mixture largely composed of carbon monoxide and hydrogen which may be withdrawn from the reactor through a discharge port 22.
  • the limestone promotes the formation of a fluid slag containing the residual ash from the combination of the coal and thus facilitates the removal of this residue from the reactor.
  • the reactor is desirably operated at an elevated pressure.
  • the fluid slag is continuously withdrawn from reactor 10 through a lateral passage 24 which connects the reactor with a quenching chamber 26 containing a body of water 28 for quenching the slag and converting it to solid granular form.
  • a quenching chamber 26 containing a body of water 28 for quenching the slag and converting it to solid granular form.
  • an oxygen lance 30 Located in the side wall of quench chamber 26 there is an oxygen lance 30 having its discharge end positioned in registry with a passage 24. The oxygen lance is useful in preventing blockage of passage 24 due to solidification of slag therein.
  • the mixture of granular slag and water in quench chamber 26 flows downwardly through discharge pipe 32 to the outlet end of a screw conveyor 34 which as shown in the drawing extends upwardly and outwardly from pipe 32.
  • a screw conveyor 34 which as shown in the drawing extends upwardly and outwardly from pipe 32.
  • the slag is transported by conveyor 34 to the upper end of a pressure lock generally designated 36 and the quench water flows through pipe 38 containing a back pressure valve 40 to a settling tank 42 wherein suspended solids are moved by sedimentation.
  • the clarified water is transferred by pump 44 through pipe 46 to the cooling tower 48 wherein it is cooled and thence by pump 50 through pipe 52 and branch pipes 54 and 56 back to the quenching chamber 26.
  • Make-up cooling water may be added to the cooling water circuit through pipe 58.
  • the pressure lock 36 may be of the general type disclosed in U.S. Patent No. 3,710,808. It comprises the hopper 60 and the double valve assemblies 62 and 64. At its upper end the conveyor 34 delivers granular slag to the accumulating hopper 66. From time to time the valves 62 are opened with the valves 64 closed to permit accumulated flag to flow from hopper 66 to hopper 60. Valves 62 are then closed and valves 64 opened to discharge the granular slag from the system.
