Publication number: 20170219168Abstract: A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.Type: ApplicationFiled: April 11, 2017Publication date: August 3, 2017Inventors: Rommel M. Oates, Solomon Dadebo

Patent number: 7881825Abstract: Method of controlling production of a plant incorporating one or more chemical processes in which products are produced through consumption of raw materials. In accordance with the method, current production rates of the products are computed by semi-empirical process models that are corrected through error corrections of actual production rates to produce corrected models. The production is then optimized using the corrected models to maximize the variable margin gained upon the sale of the products. The optimization yields targets that either directly or at least influence consumption of the raw materials. The raw materials are then introduced into the process or processes in accordance with the targets.Type: GrantFiled: March 28, 2007Date of Patent: February 1, 2011Assignee: Praxair Technology, Inc.Inventors: William R.

Patent number: 7292899Abstract: A method of controlling a distillation column having control valves to control both reflux and the vapor rate within the column. In accordance with the present invention, a temperature sensed in a top section of the column is magnified and utilized within the model predictive controller so that control is more aggressive as temperatures increase beyond a threshold temperature. Additionally, in the distillation column, or in fact in any other system in which two or more manipulated variables control two or more common controlled variables, special modeling techniques are utilized to make controller tuning easier to accomplish. In such modeling techniques, each manipulated variable is assumed to be able to have an effect on a controlled variable by a single step response model and other step response models are utilized so that the other manipulated variable(s) that also would have an effect on the same controlled variable are taken into account by the controller as feed forward variables.Type: GrantFiled: August 15, 2005Date of Patent: November 6, 2007Assignee: Praxair Technology, Inc.Inventors: Solomon A.

Patent number: 6993403Abstract: A method of monitoring plant performance within a facility in which having averages of cost contributing items such as raw material usage, product recovery, unit production efficiency, power usage and controller error performance are evaluated, statistically weighted to determine an overall performance factor. The overall performance factor applies an instantaneous indication of plant operation. Excursions of individual performance factors diagnose plant problems.Type: GrantFiled: March 22, 2005Date of Patent: January 31, 2006Assignee: Praxair Technology, Inc.Inventors: Solomon A.
