Abstract: In a device for providing heating energy to a gas-generating system by means of essentially complete catalytic combustion of a fuel on a suitable catalyst material, heat energy is transferred directly or by means of a heat-conducting medium from the catalytic burner to the gas-generating system. To improve the starting behavior and the exhaust emissions, the device comprises three components that are at least temporarily traversed by fuel, with a cold-start component having an electrical heating device. The central component is preferably designed as a filter press with an integrated heat exchanger. A third, unheated, stage is also provided for residual gas combustion.

The apparatus obtains a large amount of high purity hydrochloric acid having extremely low impurity concentration with a simple system. The inner wall of the gas supply pipe is constructed with such materials from which impurities are not eluted by hydrochloric acid at least to the position of the wall which is reached by the backward flow or splash of produced hydrochloric acid, vapor of the hydrochloric acid or water in an absorbing reactor.

Abstract: An incinerator fumes processing plant has a first reactor (1) with fumes and injected absorbent flowing longitudinally through it. The flow from the first reactor enters a second reactor tangentially. The second reactor (2) is constructed so that the flow is driven by a rotating motion so as to separate progressively, and by centrifugal effect, the solid particles from the gases. The second reactor includes means (2a, 2b) for recirculating in the plant part of the solid particles separated in the second reactor. The dedusted fumes are then discharged from the plant.

Abstract: An apparatus and a process for cooling a feed injector of a gasification reactor that produces synthesis gas is described. Cooling fluid is injected into a channel in the feed injector adapted for circulating the fluid. The injection pressure is maintained near or above the gasification reactor pressure. The fluid is withdrawn from the channel through an outlet at an outlet pressure between about 515 KPa above to about 1030 KPa below the gasification reactor pressure. The fluid is cooled, degassed, and injected back into the channel in the feed injector. The pressure on the cooling system is variable and tracks the gasification reactor pressure.

Abstract: Catalyst particles are contacted with a liquid and a gas in a vertically extending cylindrical vessel. The particles and liquid are placed in the vessel into which the gas and liquid are continuously fed from the bottom thereof so that an upwardly flowing mixture comprising the particles, liquid and gas is formed. The mixture is introduced into a gas separating zone disposed adjacent to an upper portion of the vessel to separate the mixture by gravity into a gas phase, a supernatant liquid phase and a phase rich in the catalyst particles. The gas and supernatant phases are continuously withdrawn from the separating zone while the catalyst particles-rich phase is continuously recycled to the bottom of the vessel by gravity.
