Publication number: 20230001357Abstract: The present invention addresses to a high-pressure vessel for packaging hollow fiber type membranes with application in the field of separation process with contactors with membranes aiming at a compact device/piece of equipment configured for the packaging of hollow fiber type bundles that can be used for various fluid separation processes such as liquid-liquid, liquid-gas and gas-gas, capable of working at high-pressures, enabling adequate hydrodynamic conditions and easily scalable. It is called a module the general piece of equipment, consisting of the vessel (A or C), object of the present invention, and the membranes packed inside the vessel. This piece of equipment consists of a vessel inside which the membranes are placed (14), and two heads attached at the ends (B or D). Each head has two connection points, thus allowing this device to be used with membrane contactors-type separation systems, such as “classical” permeation systems (liquid-liquid, gas-gas, pervaporation).Type: ApplicationFiled: November 11, 2020Publication date: January 5, 2023Applicants: PETRÓLEO BRASILEIRO S.A. - PETROBRAS, UNIVERSIDADE FEDERAL DO RIO DE JANEIROInventors: Jailton FERREIRA DO NASCIMENTO, Cristiano PIACSEK BORGES, Nicolas ROGER JEAN-DANIEL MERMIER

Patent number: 9890714Abstract: An auto-tune controller and tuning process implemented thereby for measuring and tuning the combustion dynamics and emissions of a GT engine, relative to predetermined upper limits, are provided. Initially, the tuning process includes monitoring the combustion dynamics of a plurality of combustors and emissions for a plurality of conditions. Upon determination that one or more of the conditions exceeds a predetermined upper limit, a fuel flow split to a fuel circuit on all of the combustors on the engine is adjusted by a predetermined amount. The control system continues to monitor the combustion dynamics and to recursively adjust the fuel flow split by the predetermined amount until the combustion dynamics and/or emissions are operating within a prescribed range of the GT engine. Additionally, a method of automated extended turndown of a GT engine to find a minimum load is provided.Type: GrantFiled: January 30, 2015Date of Patent: February 13, 2018Assignee: ANSALDO ENERGIA IP UK LIMITEDInventors: Sumit Soni, Nicolas Roger Demougeot, Peter John Stuttaford
