Patent number: 8101009Abstract: This abstract discusses membranes needed to separate fluids for the production of oxygen-enriched air, nitrogen-enriched-air, for the separation of carbon dioxide from hydrocarbons, and the separation of hydrogen from various petrochemical and oil refining streams. Membranes are needed that provide a resistance to interaction with process components or contaminants, provide the mechanical strength required to withstand high membrane differential pressures and high process temperatures, and exhibit sufficient maximum strain such that membranes are not brittle and can easily be formed into desirable membrane forms. Membranes of polyimide polymers, particularly polyimide polymers sold under the trade name P-84, are annealed in a controlled annealing step to improve the mechanical properties of the polymers used to make separation membranes.Type: GrantFiled: September 8, 2008Date of Patent: January 24, 2012Assignee: L'Air Liquide Societe Anonyme pour l'Etude Et L'Exploitation des Procedes Georges ClaudeInventors: Okan Max Ekiner, John W.

Publication number: 20120009531Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.Type: ApplicationFiled: July 31, 2010Publication date: January 12, 2012Applicants: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges Claude, American Air Liquide, Inc.Inventors: Rajeev S.

Publication number: 20110307407Abstract: Techniques are disclosed for increasing the robustness of optimization solutions for bulk gas distribution, relative to uncertain events such as unexpected plant outages. The techniques actively consider different assumptions regarding unexpected plant outages while searching for a solution (i.e., when generating a delivery schedule). A robust solution (delivery schedule) is one on which a plant outage only has a limited impact. A computer-implemented delivery scheduling application may identify a robust solution that performs well with respect to a range of uncertain future conditions (e.g., a variety of plant outages), at the lowest additional cost to the producer/distributor relative to other solutions.Type: ApplicationFiled: October 28, 2010Publication date: December 15, 2011Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Nicoleta Neagu, Hugues Dubedout
