Abstract
A discharge system for removing a solid/gas mixture from a fluidized bed pressure vessel is provided. The system includes a fluidized bed pressure vessel, settling vessels, discharge lines, primary discharge valves, vent lines, primary vent valves, crosstie lines, crosstie valves, and primary exit valves wherein the system is absent a transfer tank, and absent a filter element. The method provides for transferring a solid/gas mixture via a discharge line from the pressure vessel to a settling vessel, wherein gas is separated from the mixture, and the gas is transferred to at least one other settling vessel via a crosstie line. After the solids are transferred out of the settling vessel, the empty vessel then receives gas from other settling vessels in the system.
