A structured packing element has the shape of a rectangular flat plate, and is provided with slots and recesses. The slots are intended for assembly by interlocking the structured packing elements together in order to form the structured packing. The recesses are provided in order to form channels within the structured packing. A packing structure can be obtained by assembling such packing elements. Such a packing can be used for an operation of bringing a gas and a catalyst into contact. A manufacturing process of such a structured packing is also disclosed.

A method for treatment of a gas having 10 to 0.5% by volume of at least one of COS and CS, and 30 ppm to 5% by volume of unsaturated hydrocarbons:

Method for treatment of gas

An installation and a process which jointly implement compression of acid gases from a hydroconversion or hydrotreatment unit and gaseous effluents from a catalytic cracking unit.

Installation and process for jointly implementing compression of the acid gases from the hydroconversion or hydrotreatment unit and that of the gaseous effluents from the catalytic cracking unit

The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the Ccut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit.

Process for heating the column for distillation of the C3 fraction from an FCC unit by means of a circuit of water heated by streams belonging to units placed upstream and/or downstream of the FCC unit

This invention describes a process for mild hydrocracking of heavy hydrocarbon fractions of the vacuum distillate type or the deasphalted oil type with optimized thermal integration for the purpose of reducing the cost of the exchangers that are used as well as greenhouse gas emissions.
