摘要:
Herein disclosed is a method of separating heavy and light components from a vapor mixture. The method comprises a. distilling the vapor mixture into a first vapor phase and a first liquid phase; and b. condensing at least a portion of the first vapor phase into a second liquid phase and a second vapor phase; wherein the distilling utilizes the internal energy of the vapor mixture. In an embodiment, the method further comprises c. utilizing at least a portion of the first liquid phase to absorb at least a portion of the second vapor phase. In some cases, the method further comprises cooling the at least a portion of the first liquid phase prior to utilizing it to absorb the at least a portion of the second vapor phase.

The invention pertains to a method for processing a Fischer-Tropsch off-gas wherein Fischer-Tropsch off-gas is contacted with a wash fluid in a scrubber, and wherein the wash fluid is recycled in a closed loop with a dedicated scrubber, stripper and splitter. The wash fluid preferably is kerosene or LDF. The C 3+ hydrocarbons that are recovered from the off-gas are, together with other Fischer-Tropsch product, subjected to hydrocracking or hydrocracking/hydroisomerisation. Additionally, hydrogen is recovered from the off-gas.

The present invention relates to a method for treatment of a hot gas generated by a pyrolysis or a gasification process, wherein the hot gas is passed to a first unit for particle removal and cooling, whereby subsequently, a gaseous stream is removed from a first condensed stream thus obtained and passed to a second unit for particle removal and cooling, wherein a second condensed stream is obtained, said first condensed stream and second condensed stream being recycled to said first unit and said second unit, respectively.
摘要:
A method for purifying a combustible gas that is contaminated with contaminants, such as tar and/or dust particles, comprises feeding oil to the contaminated gas. The oil evaporates through contact with the contaminated gas. Said evaporated oil is condensed on a quantity of the contaminants in such a manner that said contaminants grow in size to form particles of increased size in the gas. An electric field between electrodes is applied, by means of which said particles of increased size are electrically charged and removed from the gas. The condensation of the oil takes place at a temperature above the water dew point of the contaminated gas. This water dew point is preferably between 50-100 °C, in particular between 50-80 °C.
