    Abstract: The invention relates to a method and apparatus for recovering power from the gaseous stream produced by an oxidation reaction. Specifically, the invention is based on heating the gaseous stream from the oxidation reaction to a temperature of at least 800 DEG C and recovering energy through a gas turbine. The compressor stage of the gas turbine compresses the oxidant feed to the reactor thereby at least partially offsetting the cost of providing the high temperature and pressure reaction conditions in the reactor. The invention also provides improved control of the power recovery system by optimising the efficiency of the gas turbine by feeding gas to the gaseous stream to modulate the flow of gas to the turbine relative to the compressor discharge flow in order to compensate for the consumption of oxidant in the reactor.

    Abstract: The invention relates to a method of preparing dinitriles, involving hydrocyanation of unsaturated nitrile compounds in the presence of a catalyst based on metallic elements in zero oxidation state and organophosphorous ligands. More specifically, the invention relates to a method of recovering a catalyst for the hydrocyanation of unsaturated nitriles into dinitriles from the hydrocyanation medium. The inventive method consists in: controlling the concentration of unsaturated nitriles in the reaction medium originating from the hydrocyanation reaction, in order to obtain a weight concentration of unsaturated nitriles of less than 20 % in said medium; and supplying the aforementioned medium in a decantation step in two phases, namely an upper and lower phase. The lower phase comprises the majority of the catalytic system, while the upper phase essentially comprises the nitriles.
