Abrégé
The present invention is related to Li and Sn (IV) amides. The amides have the formula Li2+xSn(NH2)6+x where 0 ≤ x ≤ 1. In the form of a mixture with LiH, the amides make reversible hydrogen storage possible within a temperature range of around 100° C.
The gaseous effluent to be treated is contacted in column C1 with an absorbent solution selected for its property of forming two separable phases when it is heated. The regenerated absorbent solution is separated into two phases in drum B1; a fraction rich in water and a fraction rich in reactive compounds.
Separation allows to optimize the operations performed on the regenerated absorbent solution. On the one hand, separation allows to carry out vaporization, through reboiler R1, of a fraction of the absorbent solution, preferably containing a limited reactive compound concentration in relation to the absorbent solution, thus limiting their degradation. On the other hand, separation of the phases allows to reduce the amount of solution to be treated in order to remove the non-regeneratable salts and thus to reduce the costs linked with their elimination. Finally, separation allows to eliminate the degradation products by carrying out a specific and suitable purification for each phase.
The method can be applied to combustion fumes decarbonation and to natural gas or synthesis gas deacidizing.

Method of modelling a porous geologic medium traversed by a network of fractures
A method of modelling a fractured reservoir having application for petroleum reservoir development is disclosed utilizing a set of several families of equivalent blocks of regular shapes and sizes. The fractured reservoir is modelled by a complex porous medium made up of irregular blocks. A function defining the progress of an imbibition front within these blocks, whose derivative A′(X) is calculated, is determined. A function defining the progress of an imbibition front within regular equivalent blocks, whose derivative A′eq(X) is calculated, is then determined. This derivative, which constitutes at least two line segments with distinct slopes, depends on the dimensions of the equivalent blocks. Finally, the dimensions of the equivalent blocks are obtained by adjusting the two derivatives A′eq(X) and A′(X).

Method of estimating the fracture density in a rock medium
The invention is a method of constructing a three-dimensional fracture density log of a porous formation traversed by fractures and a borehole. A number N of intersections between the fractures and the borehole is measured over a section of the borehole of length L located at a depth d, from observations of the wall of this section. A conditional probability law of the three-dimensional fracture density is then estimated, knowing the number N of intersections. The value of the three-dimensional fracture density at depth d is determined by calculating the mean of this conditional probability law. Finally, the three-dimensional fracture density log is constructed by repeating the previous stages for different depths. A three-dimensional fracture density uncertainty log can also be associated by calculating quantiles of the conditional probability law.

A function is determined that defines the propagation of a soaking front within these blocks, and the derivative A’(X) of this is calculated. A function is then determined that defines the propagation of a soaking front within equivalent uniform blocks, and the derivative A’eq(X) of this is calculated. The latter derivative, made up of at least two straight-line segments of distinct gradient, is a function of the sizes of the equivalent blocks. Finally, dimensions of the equivalent blocks are obtained by matching the two derivatives A’eq(X) and A’(X). Application in particular to the exploitation of oil deposits for example.

Method of estimating the permeability of a fracture network from a connectivity analysis
A method for optimizing the development of a fractured hydrocarbon reservoir wherein the network permeability is determined using a reliable compromise between numerical and analytical methods which has application to oil reservoir development. The reservoir is discretized into a set of grid cells and a geometrical description of the fracture network in each cell is elaborated. A connectivity index is then deduced within each cell for the fractures. The permeability of the fracture network of the cells whose connectivity index is above a first threshold is determined and a zero permeability value is assigned in the other cells. Other thresholds can be determined so as to choose between a numerical method and an analytical method to determine the permeability. These permeabilities are exploited in a flow simulator so as to optimize the development of the reservoir.

INSTALLATION FOR COOLING RECIRCULATED INTERNAL COMBUSTION ENGINE EXHAUST GASES AND CONTROL VALVE FOR THE FLOW OF SAID GASES
The invention relates to an installation for cooling recirculated internal combustion engine exhaust gases, in particular from a diesel engine, comprising a flow circuit (12) for a cooling fluid and a flow circuit for the recirculated exhaust gases (14), comprising a gas cooler (46) with an internal free space (118), through which the cooling fluid flows and a control valve (48) for the gas flow in said circuit. According to the invention, the installation comprises means for cooling said valve.
The method comprises the determination of set-point values of physical parameters linked to the intake of gaseous oxidizer into the combustion chamber, and a set-point value ϑref inf of the crankshaft angle at which a fuel must be injected into the combustion chamber. While the engine control system drives actuators so that the values of the physical parameters are equal to the set-point values, the set-point value ϑref inf is corrected before the physical parameters reach their set-point values, by taking account of the differences between the real values of the physical parameters and the set-point values of these parameters. Finally, the engine control system drives the injection of fuel into the combustion chamber when the crankshaft angle is equal to this corrected set-point value ϑref inf in order to retain optimum combustion. Applicable to combustion control in diesel engines.
