Device and method for the adsorption of a gas from a gas mixture to be treated

A device for adsorbing a gas from a gas mixture to be treated, having an inlet for gas to be treated and an outlet for treated gas, which device comprises at least two vessels filled with a regenerable adsorbent and an adjustable valve system connecting said inlet and outlet to said vessels, whereby the adjustable valve system is such that at least one vessel will treat compressed gas while the other vessel is regenerated, whereby by control of the valve system the vessels each in turn treat compressed gas sequentially, characterized in that the adjustable valve system is assembled in a single valve block;

• in that the valve block is provided with:
• one or more control valves;
• a supply channel running from the inlet to the aforementioned control val;
• a blow-off channel leading from the aforementioned control valves to a blow-off opening.

A method for adsorbing a gas from a gas mixture to be treated, using a device having an inlet for gas to be treated and an outlet for treated gas, the device comprising at least two vessels filled with a regenerable adsorbent, the method comprising using an adjustable valve system connecting the said inlet and outlet to the said vessels, whereby the method comprises

• controlling the adjustable valve system such that at least one vessel will treat compressed gas, while the other vessel is regenerated, the vessels each in turn treating compressed gas sequentially, and
• bringing the adjustable valve system together in a single valve block which is provided with:
• one or more control valves;
• a supply channel running from the inlet to the aforementioned control valves;
• a blow-off channel leading from the aforementioned control valves to a blow-off opening.
