Problems solved by technology

This will cause the device to consume more energy and end up delivering gas components at concentrations lower than required
[0005] Another drawback is the inefficiency of the adsorption process, since the duration of the adsorption cycle cannot be related to the concentration requirements of the gas components
[0006] One identified risk is the possibility of facing lower than expected concentrations of gaseous constituents, and the above documents do not provide immediate remedial measures, a fact that can jeopardize user processes or networks

Abstract

A method for controlling an adsorption phase of a gas generator, said generator comprising an adsorbent medium capable of selectively adsorbing a first gaseous component from an inlet gas flow comprising a gaseous mixture, and allowing an outlet gas flow mainly comprising a second gaseous component, said method comprising the steps of: directing the inlet gas flow through an inlet of said gas generator; measuring the outlet gas flow; determining the concentration of said second gaseous component at the outlet of said vessel,; wherein the method further comprises the steps of: A9) calculating the capacity of the generator; A10) comparing the measured outlet gas flow with the calculated capacity; All) if the measured outlet gas flow is lower than the calculated capacity, and if the determined concentration is higher than or equal to a set value, maintaining the generator in adsorption phase for a predetermined time interval, Deltas; subjecting the generator to a regenerating cycle after said predetermined time interval, Delta s.

Description

technical field [0001] The invention relates to a method for controlling the adsorption phase of a gas generator comprising an adsorbent medium capable of selectively adsorbing a first gas component from an inlet gas stream containing a gas mixture and allowing The outlet gas flow consists essentially of a second gas component, the method comprising the steps of: directing an inlet gas flow through an inlet of the gas generator; measuring the outlet gas flow; and determining the concentration of the second gas component at the outlet of the vessel. Background technique [0002] Methods of maintaining relatively constant concentrations of gas components produced by fractional distillation of gas mixtures are known in the art. [0003] An example can be found in US 4,323,370 filed in the name of LINDE AKTIENGESELLSCHAFT, where a periodic adsorption process for fractionating gas mixtures is described. The process maintains the residual concentration level of the adsorbed compo...
