Method and apparatus for injection of flue sig in a technical gas chromatographic separation device

摘要

P improvement to the process of injection of liquid in an industrial device for separation by gas phase chromatography, by means of a vaporizer scans by a vector, the liquid being bring to the vaporizer by a pipe having a valve whose opening and closure allow the injection is a flow gives determined of the quantity of liquid, the purging of the fluid contained in the evaporator and the adjacent pipes at the end of the injection and the purge slow continuous between the injections being provided by a system of valves characterizes in that the vaporization instant is insured with a reboiler exchanger and that a derivation makes it possible to the vector gas of the short - circuited the vaporizer is the closing of the injection, while supplying the tubing. / p
