An entrained flow gasifier designed as a component for an Integrated Gasification Combined Cycle plant of optimized efficiency is provided. The raw gas initially flows through a waste heat unit designed as a radiation cooler and subsequently flows through a full water quench. This results in a higher ratio of steam in the raw gas, which decreases the medium-pressure steam supply before the water-gas shift and thus improves efficiency in IGCC plants with CO 2 separation.

Process for the purification of crude gas from solids gasification

Номер: US20140044601A1
Автор: Johannes Kowoll
Принадлежит: UHDE GMBH

A process and device is provided for the generation and purification of a crude gas for synthesis gas generation from a solid carbon-containing fuel by a coal gasification reaction. The fuel is mixed with a quenching medium directly after generation to dissipate the internal energy and is then brought into contact with a compound or a sorbent in the mixing chamber or downstream of the mixing chamber such that the acidic or basic or sulphur-containing or halogen-containing constituents contained in the crude gas and originating from the gasification reaction are absorbed. A solids-separating device removes the solid or solidified constituents from the system. The sorbent can be regenerated and returned to the process such that an energy-intensive cooling of the crude gas is not required for its purification and the synthesis gas thus purified can be used in a subsequent process without any further heating.

A process to efficiently convert organic feedstock material into liquid non-oxygenated hydrocarbons in the Cto Ccarbon skeleton range is disclosed. The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the Cto Ccarbon backbone range.

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.

Processes and apparatuses are described for the selective removal and recovery of acid gases from a gas source comprising at least hydrogen sulfide and carbon dioxide. A step-wise approach is illustrated wherein hydrogen sulfide may be selectively removed from a gas source by treatment with methanol under conditions where substantially all the hydrogen sulfide may be removed. The partially purified gas source may then be provided with a second treatment with methanol under conditions which selectively remove carbon dioxide from the gas stream. Such methods are generally applicable to any gas source comprising at least hydrogen sulfide and carbon dioxide, for example, a gas source produced from the catalytic gasification of a carbonaceous material, the combustion of a carbonaceous material, or the oxy-blown gasification of a carbonaceous material.
