Abstract: The invention provides a catheter including: a first lumen adapted for draining a first fluid from a subject; a second lumen adapted for passing a second fluid through the second lumen; and a third lumen adapted for passing a third fluid through the third lumen such that the third fluid can exit the third lumen to bathe at least a part of an outside surface of the catheter. The invention further provides a kit and/or system including said catheter and method of use for said catheter.

Abstract: The invention relates to a system and method for the hydrothermal oxidation of water-insoluble organic residues. The plant comprises two independent liquid phase feed lines, namely an aqueous phase (1) and a non-water-soluble phase (9). The supercritical conditions in the entrance to the first reactor (10) enable a homogeneous phase to be obtained, in which there are no solubilization problems, thereby enabling the treatment of industrial residues that cannot be treated with standard systems. The inventive system comprises two reactor sections (14 and 18) such that it is possible to inject streams of hydrogen peroxide (11 and 15) in the connections between sections (13 and 17), in order to potentiate the oxidation reaction. The plant is equipped with a heat exchange system (5) in order to make use of the energy generated during the oxidation process, such that the plant operates in autothermal conditions.
