ABSTRACT:
The Takahax gas desulfurization method is rendered more energy-efficient and compact by providing separate scrubbing and regeneration loops operating from a common reservoir (31,33) and by using hyperbaric pressure in the oxygenating or regenerator vessel (59). The overall height of a plant of comparable capacity can be reduced from the 13 meters (about 40 feet) required by the prior art to 3.3 meters (10 feet) and can therefore be transported by truck. The preferred washing or scrubbing liquid is an alkaline solution using sodium 1,4 napthoquinone-2-sulfonate as the catalyst. By oxidation, elemental sulfur is made to precipitate and this is filtered out continuously in a filter (77). Regenerated washing liquid flows via a degassing vessel (69) into the common reservoir (27,31,33). In the degassing vessel, under relaxed pressure, degassing occurs, and the sulfur foam, along with the oxygen or air it contains, is returned via a pump (55) to the regenerator pressure vessel (59) or to the filter (77).
