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

Patent number: 9920929Abstract: Biomass is quickly becoming an important feedstock for energy generation in power plants. Due to their composition and nature, certain biomass fuels contribute to slagging, fouling, and corrosion. This invention provides a novel method of reducing or suppressing slag deposition and/or cleaning deposited slag in energy production processes in which potassium-containing solid fuels are combusted. Besides acting as a slag suppressant, further advantages of this invention are that the additive has no detrimental side-effects on capital equipment, increases slag friability, decreases slag fouling rate, reduces heat transfer corrosion as well as increasing the lifetime of the selective catalytic reduction catalyst.Type: GrantFiled: June 13, 2011Date of Patent: March 20, 2018Assignee: Ecolab USA Inc.Inventors: Robert W.
