Abstract: The object of the invention is a method of controlling a permanent-magnet synchronous or synchro-reluctant three-phase rotary machine (4), comprising the following steps:
measuring a current (iA, iB, iC) flowing through each phase of a stator of rotary machine (4);
first calculating, by use of a single proportional-integral controller, a switching control signal for controlling an inverter (10), according to each measured current (iA, iB, iC), and of a target value (Tref) of a mechanical torque provided by the rotary machine (4) or of a target value of an angular speed of a rotor of rotary machine (4) in relation to the stator wherein the inverter (10) is configured to convey electrical energy between a continuous electrical energy source (8) and each phase of the stator of rotary machine (4); and controlling the inverter (10) by use of the calculated switching control signal.-

Abstract: The invention relates to a method for recovery of hydrocarbons present in an underground formation by injection of a saline aqueous solution comprising at least one surfactant, by means of a numerical flow simulator including a model of the evolution of the interfacial tension between the saline aqueous solution and the hydrocarbons as a function at least of salinity, wherein the interfacial tension evolution model is calibrated as follows: i) carrying out interfacial tension measurements for a plurality of emulsions having distinct salinity values corresponding at least to the optimum salinity, to two salinities bounding the optimum salinity in a 5-10% limit, to the zero salinity and to the solubility limit of the salts; ii) determining the constants of the interfacial tension evolution model by minimizing a difference between the model and the interfacial tension measurements.

Abstract: The invention describes a mass for scavenging mercaptans which is particularly suitable for the treatment of olefinic gasoline cuts containing sulfur such as gasolines resulting from catalytic cracking. The scavenging mass comprises an active phase based on group VIII, IB or IIB metal particles which is prepared by a step of bringing a porous support into contact with a metal salt of said group VIII, IB or IIB metal and a step heating the resulting mixture to a temperature above the melting point of said metal salt. The invention also relates to a process for using said scavenging mass for the adsorption of mercaptans.

Abstract: The present invention relates to a method of characterizing organic hydrocarbon compounds contained in a solid deposit of a geothermal plant, by measuring a quantity of organic hydrocarbon compounds released by a solid deposit sample during heating by pyrolysis according to a temperature sequence such that: from a temperature (T1) ranging between 50° C. and 120° C., the temperature of a rock sample is raised to a temperature (T2) ranging between 180° C. and 220° C. This temperature (T2) is then maintained for a predetermined duration. The temperature of the sample is raised to a temperature (T3) ranging between 330° C. and 370° C. This temperature (T3) is maintained for a predetermined duration. The temperature of the sample is thereafter raised to a temperature (T4) ranging between 630° C. and 670° C.

Abstract: The present invention relates to a device and a process for converting aromatic compounds, wherein: methyl-substituted aromatic compounds are extracted from a hydrocarbon feedstock (2) comprising aromatic compounds having at least 8 carbon atoms in an extraction unit (1), to produce at least one effluent enriched in methyl-substituted aromatic compounds (3A, 3B) and an effluent depleted in methyl-substituted aromatic compounds (4); and C2+ alkyl chains of the aromatic compounds of the depleted effluent (4) are converted into methyl groups in a hydrogenolysis unit (5) placed downstream of the extraction unit (1), to produce a hydrogenolysis effluent enriched in methyl-substituted aromatic compounds (7).

Abstract: The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300° C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250° C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h−1. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300° C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.
