Patent number: 11255486Abstract: A pretreatment system and method for a floating liquid natural gas (“FLNG”) facility are presented. The inlet natural gas stream flows through a membrane system to remove carbon dioxide and a heat exchanger, producing first and second cooled CO2-depleted non-permeate streams. The first cooled CO2-depleted non-permeate stream is routed to additional pretreatment equipment, while the second cooled CO2-depleted non-permeate stream is routed directly to a LNG train. Alternatively, the inlet natural gas stream may flow through a membrane system to produce a single cooled CO2-depleted non-permeate stream that is routed to the LNG train after sweetening and dehydration. Because the pretreatment system delivers the incoming gas stream to the LNG train at a lower temperature than conventional systems, less energy is needed to convert the gas stream to LNG. In addition, the pretreatment system has a smaller footprint than conventional pretreatment systems.Type: GrantFiled: October 16, 2017Date of Patent: February 22, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Ankur D. Jariwala, Richard D. Peters

Patent number: 10427094Abstract: A membrane permeation system and process accommodates varying acid gas inlet concentrations over time while utilizing only the initially installed equipment and still maintaining the non-permeate gas specification. The system and process provide flexibility to operate efficiently over a wide range of inlet CO2 concentrations by adjustments to primary permeate, secondary permeate, and recycle gas operations. The glassy polymer membrane devices used in the system and process are selected so removal duty efficiency increases as acid gas concentration increase. Designing the system and process to handle about a 15% increase in acid gas concentrations over initial conditions effectively treats acid gas concentrations well above that 15% increase, thereby eliminating the need for additional equipment or for additional downstream amines and physical solvents.Type: GrantFiled: July 15, 2016Date of Patent: October 1, 2019Assignee: Cameron Solutions, Inc.Inventor: Richard D.

Publication number: 20170226438Abstract: A membrane filter element includes at least two cylindrical-shaped, fiber bundles, one of the fiber bundles containing first fibers fabricated to provide a selected first gas selectivity, a selected first gas permeability, or a selected first gas selectivity and permeability performance and arranged so a first gas permeate exits the membrane element; another of the fiber bundles containing second fibers fabricated to provide a selected second, different gas selectivity, a selected second different gas permeability, or a selected second gas selectivity and permeability performance and arranged so a second different gas permeate exits the membrane element. The different performance characteristics can reduce the number of membrane elements required for gas separation and to improve gas separation performance due to changing gas composition as the gas travels through the membrane element.Type: ApplicationFiled: April 24, 2017Publication date: August 10, 2017Inventors: Richard D.

Patent number: 8276715Abstract: A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain time metrics. The controller receives a hall call signal, and based on certain time metrics that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT), assigns the call signal to an elevator car. In this example, EWT represents the time a passenger is waiting for an elevator car to arrive, and ETT represents the it takes for a passenger to reach their destination once having boarded an elevator car. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign, where ETD represents the sum of EWT and ETT. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.Type: GrantFiled: December 27, 2011Date of Patent: October 2, 2012Assignee: ThyssenKrupp Elevator Capital CorporationInventors: Rory S.
