Abstract
Systems and methods for producing a product gas are provided. In one embodiment, a system includes at least one separation bed to separate adsorbable components from a gas source, a valving means to selectively direct gas from the gas source to the at least one separation bed, at least one sensing device associated with the at least one separation bed to sense the progress of an adsorption zone within the separation bed, and a controller. The controller includes logic to read the output of the at least one sensing device and control the gas separation process based on the progress of the adsorption zone.
Claims20
A system for producing a product gas, comprising:
- a product gas separator, comprising a first separation bed to separate adsorbable components from a gas source;
- at least one sensing device associated with the first separation bed to sense the progress of an adsorption zone within the first separation bed and provide an output;
- a memory to store an original control parameter and an adjusted control parameter;
- a controller, comprising logic to:
- read the output of the at least one sensing device;
- determine the adjusted control parameter based on the output of the at least one sensing device;
- store the adjusted control parameter in the memory;
- and
- control the separation of the adsorbable components from the gas source based on the stored control parameter, wherein the stored control parameter is based on non-ideal conditions occurring during separation of the adsorbable components.
A method of producing a product gas, comprising:
- reading a first set of operating parameters;
- reading an output of a first sensing device associated with the progress of an adsorption zone within at least one separation bed;
- determining a second set of operating parameters based on the output of the first sensing device;
- storing the second set of operating parameters in a memory;
- and
- producing the product gas based on the stored set of operating parameters, wherein the stored set of operating parameters is based on non-ideal conditions occurring during production of the product gas.
