<p>The process comprises injecting, in the fluid compound after mixing several compounds, an inert gas (4) driving at a pressure that is greater than an equilibrium pressure of the inert gas in the fluid compound, injecting the fluid compound containing the inert gas in an intermediate buffer tank (6), applying a differential pressure between the injection point of inert gas and the entry point of mixture of compound/inert gas in the tank, and providing the regulation of the gaseous atmosphere of the tank, by injection of inert gas under pressure or ejection of gas, to obtain an overpressure. The process comprises injecting, in the fluid compound after mixing several compounds, an inert gas (4) driving at a pressure that is greater than an equilibrium pressure of the inert gas in the fluid compound, injecting the fluid compound containing the inert gas in an intermediate buffer tank (6), applying a differential pressure between the injection point of inert gas and the entry point of mixture of compound/inert gas in the tank, providing the regulation of the gaseous atmosphere of the tank, by injection of the inert gas under pressure or ejection of gas, to obtain an overpressure relative to an liquid/gas interface (21), where the relative overpressure is lower than the equilibrium pressure of the inert gas in the fluid compound, providing the evacuation of gas entrained by driving the inert gas, and conveying the fluid compound in direction of a downstream processing unit such as a gasification unit (11) and/or an extraction unit (10). The differential pressure, between the injection point of the inert gas and the entry point of the mixture of fluid compound/inert gas in the buffer tank, is obtained by applying a pressure relative to the entry point that is lower than the pressure of the injection point of the inert gas in the fluid compound. The relative overpressure is maintained at the liquid/gas interface in the buffer tank by injection of the inert gas under pressure.</p> |
