Abstract: 1421148 Cleaning exhaust gases from steelmaking converter K BAUM [trading as VERFAHRENSTECHNIK DR ING KURT BAUM] 20 Dec 1972 [20 Dec 1971] 58872/72 Heading C7D [Also in Division F4] A steel making converter 10 comprises tuyeres 16 through which O 2 , N2, Air, Ar, and hydrocarbons can be blown in the hydrocarbon surrounding the O 2  blast, and a gas-collection unit comprising a water-cooled hood 27 and a movable skirt 28. The off-gases pass into a stack 40 and a Venturi scrubber 41, thence to a secondary Venturi scrubber 44, and then either through valve 54 or to a stack 51 and torch 52. The skirt 28 can be adjusted either to allow air to enter the hood 27 and react with the off-gases, or to seal the hood. The scrubbed off gases are monitored by a partial pressure sensor 68 (for O 2 ) and an infra-red sensor 69 (for CO, CO 2 , and H 2 O), and when the off-gases reach the desired calorific value they are directed through pipe 53 and valves 58 to storage. The sensor 68 also. monitors changes in combustion conditions and shuts down the skirt 28 when stoichiometric conditions are achieved. When the converter 10 is tilted, the gases are collected by auxilliary hood 66. Powdered materials, e.g. iron oxide, CaCO 3 , CaO, CaF2 may be introduced through the tuyeres from container 31.

Patent GB-2000822-A (GB)
Title: A method of rendering lignin separable from cellulose and hemicellulose in Lignocellulosic material
IPC: A23K10/32
Filed: 1978-07-11
Abstract: Lignocellulosic material is packed in particulate form in a pressure vessel, steam is passed into the pressure vessel at a pressure of at least 500 psi to bring the lignocellulosic material to a temperature in the range 185 to 240 DEG C in less than 60 seconds to plasticize the lignocellulosic material and as soon as the material is plasticized it is extruded through a die to atmosphere to form a particulate material. During extrusion the softened material is subjected to severe deformation and then severe mechanical shock thus fracturing the linkages between lignin,the hemicellulose and the cellulose. The temperature range and rapid rise thereto by the material substantially minimizes degradation of the fragile hemicellulose. The process converts lignocellulosic material into a substrate which is extremely easy to treat by enzymes, either as a feed for ruminant animals or for conversion to sugars and alcohols and for the solvent extraction of lignin.
