Document Type and Number:
Japanese Patent JP3005697
Kind Code:
B2
Abstract:
Process for the removal of mercury throughout a steam cracking plant, characterised in that the regeneration ends in the injection of the regenerating gas into one of the demercurising active masses so that there is substantially no trace of mercury in the air or in the liquids leaving the said plant.
By way of example, the process comprises the use of three demercurising masses, namely: two upstream of the plant, in series (mass 1 and mass 2) and one downstream (mass 3), which is demercurised by at least one of the upstream masses. The use applies in particular to the decontamination of steam cracking plants already contaminated with mercury.
