    Abstract: The present specification describes and claims a method and apparatus for use in cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials. The residue of gasification is conducted out of the reactor into a cooling apparatus located therebelow and flows through the cooling apparatus from the top to the bottom thereof. A cooling liquid is introduced into the solid residue in the upper region of the cooling apparatus and is metered such that the greater portion of the heat contained in the residue is eliminated in the form of heat of vaporization, sensible heat and chemical binding energy with the resultant steam and reaction products produced. The remaining residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchange.

    Abstract: An improved valve apparatus for the introduction of finely divided coal solids into a vessel in a controlled manner is disclosed. The disclosed apparatus includes substantially vertical and horizontal conduits interconnected to provide a generally continuous L-shaped flow path therethrough. Gas is introduced directly into the bottom portion of the vertical conduit upstream from the point where the vertical conduit and horizontal conduit interconnect. The flow rate of the gas introduced into the vertical conduit is controlled to adjust the amount of coal solids discharged from the discharge end of the horizontal conduit.

    Abstract: A process for converting a finely divided carbonaceous material, particularly coal, to a fuel gas. A finely divided or pulverized carbonaceous feed material, such as coal, is pretreated at a temperature of about 700.degree. - 800.degree. F in order to destroy the caking properties of a caking coal feed in a fluidized pretreatment zone, or, alternatively to dry a non-caking coal feed. The pretreated coal is passed from a pretreatment zone to a gasification zone wherein the carbonaceous feed material or coal is maintained as a fluid bed at selected conditions for converting the pretreated material to ash and a gaseous mixture. During the pretreatment of the feed material, hot off gases are formed and the hot off gases, which generally comprise steam, tars, oils, and carbonaceous fines, are passed from the pretreatment zone to the underside of the fluid bed in the gasification zone. The steam contained in the off gases is reacted with the coal in the fluidized bed in the gasification zone for converting the coal feed material to ash and the fuel gas product. The off gases also provide heat for maintaining the desired temperature conditions in the gasification zone. The tars and oils in the off gases are substantially destroyed during passage upwardly through the fluidized bed in the gasification zone. The fines in the off gases are converted by the gasification reaction in the gasification zone to form a part of the fuel gas and the ash. The fuel gas is withdrawn from the upper portion of the gasification zone and ash is withdrawn from the bottom of the gasification zone.

    Abstract: Disclosed are cooling and depressurization system equipment, arrangement and methods to cool solid particles from a coal gasifier operating at high temperature and pressure. Ash from the coal needs to be continuously withdrawn from a circulating fluidized bed gasifier to maintain the solids inventory in the gasifier. The system disclosed enables use of conventional materials of construction for heat transfer surfaces. The supports for the cooling surfaces are located on the lower temperature upper section of the primary cooler. The cooled solids along with the fluidizing gas exits the primary cooler to a secondary receiving vessel where the solids can be further cooled by conventional means. The fluidizing and entrained gas entering the secondary vessel is filtered and vented through a vent pressure control valve. The column of cooled solids in the secondary vessel is depressurized by a continuous depressurization system to low pressures which are sufficient for conveying the solids to silos for disposal. The system and methods proposed are equally applicable to many high temperature, high pressure processes that require cooling and depressurization of process solids.
