Patent attributes
A gas blending and compressing system includes a blender having a blending chamber configured to blend two or more separate gases into a blended gas, a compressor configured to compress the blended gas to a selected pressure, and a control system configured to sense operational parameters of the blender and the compressor, to sense one or more properties of the blended gas and to control the operation of the blender and the compressor to maintain the quality of the blended gas. A method for blending and compressing two or more gases includes the steps of: blending the separate gases into a blended gas using the blender; compressing the blended gas using the compressor; and matching a constant flow through the compressor to a selected minimum flow dependent on nominal operating parameters of the compressor. Alternate embodiment systems and methods blend separate gases at high pressure without using a compressor. Various principles are applied at high pressure including choked flow and partial pressure blending.
