    摘要： A process for the purification of natural gas to render it suitable for liquefaction comprises passing a stream of natural gas containing water, methanol and carbon dioxide is passed at elevated pressure along line 20 to a vessel A containing a first bed portion 21 of an absorbent material on which water and methanol are absorbed and a second bed portion 22 of an absorbent material on which carbon dioxide is absorbed. A stream of purified natural gas 23 issues from the vessel A and is passed to a liquifaction plant or any other subsequent process or use. A portion of the purified natural gas about 10%, is passed along line 24 to a vessel B which contains a first bed portion 26 and a second bed portion 25 which have previously absorbed water and methanol, and carbon dioxide, respectively. The gas is passed to vessel B at a reduced pressure and the beds of absorbent material thereby regenerated.

    摘要： A process for the separation of foreign matter from a liquid, which process comprises mixing a stream of contaminated liquid containing dissolved gas with a stream of induced gas to provide a multi-phase flow, subjecting the multi-phase flow to turbulence and shearing thereby to produce a well dispersed bubbly liquid stream, passing the bubbly liquid stream into a vessel which contains the liquid contaminated with foreign matter, below the free surface of the liquid, and allowing the bubbles of gas to rise to the surface of the liquid, the surface adherence between the gas bubbles and the particles of foreign matter causing the particles of foreign matter to float to the surface of the liquid.
    Also provided is an apparatus for the separation of foreign matter from a liquid and a nozzle for the production of a bubbly liquid.
