Abstract

1319471 Regenerating carbon beds HITACHI Ltd 28 Aug 1970 41581/70 Heading B1L Carbon adsorption beds 8a, b, c, are reactivated by feeding water to each bed in turn through 17a, b and c, while still feeding gas to be purified to the beds, including the bed being reactivated. The gas to be purified may be sulphur oxide containing flue gas.
