              Kassel plant of the Braunkohlen and Brikett Industrie A.-G., Bubiag, for degasifying brown coal by parallel-flow process is described.  The raw-gas yield for purposes of synthesis amounts to 1,100-1,800 m.³ per ton at normal temperature and pressure.  The CO:H₂ ratio can be adjusted exactly to 1:2 to suit the Fischer benzine-synthesis process without special preparation.  An installation of 12 parallel-flow retorts 32 ft. 10 in. in height has been in continuous service in Hungary since 1932, making about 70,000 m.³ of synthesis gas per day.  Plants of any desired capacity can be supplied under guarantee for the manufacture of town gas or synthesis gas.
