Embodiments of the disclosure relate to a plant matter burning or vaporization apparatus comprising a plant matter receptacle for containing plant matter, and a burning/vaporization region for burning or vaporization of plant matter to produce a plant compound vapor, and a plant matter conduit operable to continuously convey plant matter to the burning/vaporization region. Embodiments of the disclosure also relate to a solvent combination apparatus comprising or operatively connected to a vapor conduit located at or at a distance from the burning/vaporization region, from which the plant compound vapor is removed from the environment of the plant matter and conveyed to a solvent in which the plant compound vapor is dissolved. The dissolution of the plant compound vapor in the solvent may be assisted by passing the solvent and smoke/vapor through a nozzle creating a region of high pressure.

The invention relates to a gas scrubbing process and a corresponding plant for removal of acidic gas constituents from crude synthesis gas which make it possible by treatment of shifted and of unshifted crude synthesis gas in the gas scrubbing process and by combination of the thus-obtained partial product streams to produce a plurality of gas products having different compositions. In addition, the invention ensures that the flash gases obtained during decompression of the laden scrubbing medium are utilized materially and/or energetically in advantageous fashion.

Methods are provided to use water-free quench liquids to obtain pyrolytic liquid products with reduced formaldehyde content. Products include liquids with improved hydroxyacetaldehyde content.

The present invention relates to an improved process and system for purifying a gas, preferably an energy gas, containing aromatic compounds and isolating a fraction of aromatic compounds from said gas. In the process according to the invention, the gas is contacted with a washing liquid in step (a), at a temperature of 15-250° C., to obtain a purified gas, which is depleted in aromatic compounds, and a spent washing liquid wherein the aromatic compounds are dissolved. The spent washing liquid is stripped in step (b) with a stripping gas comprising at least 50 vol. % steam, to obtain a stripped washing liquid which is advantageously reused in step (a) and a loaded stripping gas comprising the aromatic compounds. The aromatic compounds are separated from the loaded stripping gas in step (c) by condensation of the steam and/or the aromatic compounds comprised in the loaded stripping gas to obtain an immiscible composition and isolating the aromatic compounds therefrom. The cleared stripping gas which is advantageously reused in step (b).
