  • Process and apparatus for winning oil from a vapor gas mixture
    Patent number: 9034076
    Abstract: A process for winning oil from a vapor gas mixture (VGM) containing a plurality of oil fractions obtained by the pyrolysis of a hydrocarbon containing material includes dedusting and cooling the VGM. The dedusted and cooled VGM are fractionated in at least two electrostatic precipitator stages at respective temperatures corresponding to respective boiling points of the oil fractions so as to separate the oil fractions.
    Type: Grant
    Filed: October 10, 2012
    Date of Patent: May 19, 2015
    Assignee: ENEFIT OUTOTEC TECHNOLOGY OÜ
    Inventors: Hermann Sieger, Christian Binder, Hans-Joachim Werz, Nikola Anastasijevic, Andreas Orth, Aleksandr Kaidalov, Kirill Kaidalov

  • Process for sintering iron oxide-containing materials on a sintering machine
    Patent number: 5476533
    Abstract: A sinterable mixture comprising iron-containing materials and solid fuel is sintered on a sintering machine; to decrease the rate at which exhaust gas is to be removed and to produce a desirable sinter, a part of the exhaust gas is enriched to an oxygen content of up to 24% by the addition of higher-oxygen gases and is then recirculated as a recycle gas, and exhaust gas is removed as a tail gas from the process only at a rate which corresponds to the rate of the gas which is formed during the sintering process plus the rate of the gas added for enriching plus the rate of inleaked air which has infiltrated from the outside minus the rate of oxygen consumption.
