摘要： An apparatus for a three-stage cooling and scrubbing system for the treatment of hot crude gases and liquid slag downstream of an entrained flow gasification. Crude gas and slag are firstly cooled and prescrubbed in a first stage by injection of water from ring and/or wall nozzles into a free quench space. Crude gas and slag are then fed together with excess water into a waterbath as a second stage before intensive spraying is once again carried out as a third cooling and scrubbing stage in an annular space.

摘要： A technology for producing synthesis gas from crude gas from various gasification processes for solid or liquid fuels. To limit the temperatures in a subsequent strongly exothermic CO shift reaction to adjust the H2/CO ratio, the crude gas which has been freed of dust flows through two shift reactors arranged in series. The first reactor has a specific reaction-kinetically limited catalyst and the second reactor has a conventional sour gas catalyst. The specific catalyst used in the first reactor limits the exothermic shift reaction to such an extent that the reaction temperatures in the first and second reactors remain so low to avoid thermal damage to the catalysts even without introduction of external steam, and the desired gas composition is achieved.

摘要： A multistage gas washing system is applied for dust separation from crude gases of entrained flow gasification of pulverized fuels under pressures up to 10 MPa and temperatures which are greater than the melting point of the fuel ash. A first stage comprises a modified quenching system and a downstream washing column, which operates as a bubble column. A second washing stage comprises one or more Venturi washers connected in series. A third washing stage comprises multiple high-pressure atomization units of washing water, a partial condenser for cooling the crude gas by 1 to 15° C. with condensate formation, and a separation column, which is equipped with washing surfaces and a plastic-coated demister.

摘要： A three-stage quenching and scrubbing system for treatment of hot crude gases and liquid slag after an entrained flow gasification. In the first primary stage, cooling and scrubbing water is injected such that slag can no longer adhere to the wall of the central tube and the conversion reaction of the carbon monoxide with water vapor to give hydrogen can proceed to close to the equilibrium. A secondary quenching and scrubbing stage takes the form of a bubble column, and further cooling and the deposition of coarse dust and slag are effected in a water bath. The rest of the treatment is through intensive spraying in a tertiary quenching and scrubbing the gas stage, nozzle rings for deposition of fine slag and partly of fine dust. All three quenching and scrubbing stages enable cooling of the crude gas down to the water vapor dew point determined by the plant pressure.

摘要： A process for treating steam-saturated crude gases from an entrained flow gasification of fuels before entry into heat exchangers sited upstream of a crude gas converting operation. To avoid solid deposits in an entrance region of the heat exchangers, the crude gas is converted from a saturated into a superheated state by supply of a hot gas to the crude gas. Hot gas contemplated is superheated high pressure steam or recycled superheated converted crude gas.

摘要： Devices for a three-stage scrubbing system for treatment of hot crude gases and liquid slag by an entrained flow gasification. Crude gas and slag are conducted downward into a water bath in a central tube. The upper part of the central tube consists of a double-threaded tube screen welded in a gas-tight manner, in which water is injected directly as the first scrubbing and cooling stage in the interior thereof. In the water bath, a bubble column is formed, which simultaneously constitutes the second scrubbing and cooling stage. Surface bodies arranged in three layers increase the scrubbing effect. After leaving the bubble column, the crude gas is again sprayed with water in a cavity, wherein one or more nozzle rings are disposed. This forms the third scrubbing stage. The crude gas then leaves the quenching and scrubbing apparatus in steam-saturated form at 200-220° C. and is sent to further treatment.
