The invention relates to processes for the combustion of liquid fuels, including a means of using an oxygenated gas in a combustion zone, applicable to steam boilers, which produces a longer, more uniform and cooler oxygen flame than a conventional oxygen flame. According to the invention, the liquid fuel is injected into the combustion zone in atomized form, the fuel being atomized by bringing a stream of fuel into contact with a stream of atomizing fluid, and:

Process for the oxycombustion of a liquid fuel

A method of PSA gas separation for a gas mixture containing hydrogen and hydrocarbon impurities. The gas mixture is put in contact with silica gel and activated carbon so as to adsorb the impurities in the gas mixture. Hydrogen rich and waste gas flows are produced. The waste gas flow may be sent to the combustible network of a petrochemical site, without having to make a pressure adjustment to the waste gas.

Treatment of hydrogen/hydrocarbon mixtures on adsorbents regenerated at high pressure

A method of treatment of a gas mixture which contains H, HS and possibly of other impurities, such as hydrocarbons. The treatment method is aimed at purifying the hydrogen mixture without incurring a overall pressure loss. The method according to the invention uses a device for pressure swing adsorption where the device includes an integrated compressor. In each adsorber of the device a pressure swing cycle is carried out which includes the steps of: adsorption, decompression, purge, and repressurization.

Method for treatment of a gaseous mixture comprising hydrogen and hydrogen sulphide

A method and an apparatus for enriching a combustible gas. The gas mixture is initially flowing in a distribution line at a set pressure. Part of the mixture is bypassed to a separate line where it is then compressed. This compressed stream is then treated in a gas separation unit and is injected back into the distribution system at about the set pressure.
