Patent number: 11891309Abstract: A method of controlling cooling water treatment at a cooling tower may involve measuring operating data of one or more downstream heat exchangers that receive cooling water from the cooling tower. For example, the inlet and outlet temperatures of both the hot and cold streams of a downstream heat exchanger may be measured, optionally along with a flow rate of the cooling water stream passing through the heat exchanger. Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger. The heat transfer efficiency can be trended over a period of time and changes in the trend detected to identify cooling water fouling issues. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the changes in heat transfer efficiency detected at the downstream heat exchanger.Type: GrantFiled: September 13, 2018Date of Patent: February 6, 2024Assignee: Ecolab USA Inc.Inventors: Anupam Prakash, Stephen J. Hinterlong, Hung-Ting Chen, Craig Myers, Walter H. Goodman, Daniel Meier

Publication number: 20230380952Abstract: A branched stent graft includes a main body aligning with a blood vessel in a radially expanded state and extending between proximal and distal ends. The branched stent graft includes a coupling or a fenestration window proximate a branching blood vessel in the radially expanded state. The main body includes a proximal body stent at least partially located between the proximal end of the main body and the coupling/fenestration window and a distal body stent at least partially located distal the coupling/fenestration window. The main body includes a surrounding region located between the proximal and distal body stents and extending along a main body circumference. The main body further includes a support stent located in the surrounding region and configured to maintain the main body in an open state when aligned with the blood vessel. The support stent imparts less radial force than the proximal and distal body stents.Type: ApplicationFiled: May 16, 2023Publication date: November 30, 2023Inventors: Sydney M. GUSTAFSON, Todd S.

Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger.

Multiple potential causes of the perceived fouling issues can be evaluated to determine a predicted cause. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the predicted cause of the fouling.Type: ApplicationFiled: May 17, 2023Publication date: September 14, 2023Inventors: Craig Myers, Anupam Prakash, Ravindra Raghavapudi, Steven Kramarczyk, Stephen J.

Publication number: 20220226782Abstract: Membrane filtration systems can be used to purify liquid streams for downstream use. In practice, foulant can build-up on the surface of a membrane within a filtration system over time. The effectiveness of the filtration system will deteriorate if the fouling is not properly controlled. In some examples, a method of controlling membrane fouling in a pressurized membrane system involves supplying a feed stream that is predominately air mixed with water to the membrane. In other words, the feed stream a greater volume of air than water, even though it is the water being processed by the membrane. Supplying the pressurized membrane system with a feed stream that contains a greater volume of air than water can yield significantly better performance than supplying the membrane with a feed stream that contains a greater volume of water than air.Type: ApplicationFiled: January 16, 2022Publication date: July 21, 2022Inventors: Seong-Hoon Yoon, Hui Li, Craig Myers, Daniel Meier, Donald Johnson

Patent number: 6699019Abstract: A system for pumping water from a well (32) drilled into an underground water source (44) that is operable in association with the windmill (10) having a tower frame (14), a wind driven turbine (12), and a reciprocating pump shaft (16) operably connected to the turbine. The system includes an air pump (20) mechanically linked to the reciprocating pump shaft (16) of the windmill (10) and operable by the direct reciprocating motion of the shaft (16). The air pump (20) operates through the reciprocating motion of the windmill shaft (16) and delivers a flow of compressed air into the well (32) down to a point below the water level within the well (32). An air lift fluid pump (20, 36) is positioned within the well (32) and comprises a submerged mixing chamber wherein compressed air is injected into the mixing chamber forming a buoyant air-water mixture. This buoyant mixture flows towards the surface which in turn draws water up through the fluid conduit (38) to the surface.Type: GrantFiled: December 12, 2002Date of Patent: March 2, 2004Inventors: Steven Craig Myers, Allan Curtis Hogue
