Patent number: 11970393Abstract: A method of controlling a chemical reaction is disclosed. The method may include feeding a solution at a first flow rate into a reactor and detecting a sound in the reactor using a sound sensor that is adjacent to the reactor. The sound sensor may convert the sound into a sound signal. After the sound signal is acquired, it is compared to a stored sound signal or a stored sound threshold to detect a reaction event. The method may include adjusting the flow rate of solutions into the reactor in response to the reaction event.Type: GrantFiled: July 3, 2019Date of Patent: April 30, 2024Assignee: ECOLAB USA Inc.Inventors: Kun Xiong, Nicholas Ryan Denny, Stephen Joseph Hinterlong, Emily Rader, David R.

Patent number: 11285439Abstract: A method for the reduction and prevention of mercury emissions into the environment from combusted fossil fuels or other off-gases with the use of peracetic acid is disclosed. The peracetic acid is used for the capture of mercury from the resulting flue gases using a flue gas desulfurization system or scrubber. The method uses peracetic acid in conjunction with a scrubber to capture mercury and lower its emission and/or re-emission with stack gases. The method allows the use of coal as a cleaner and environmentally friendlier fuel source as well as capturing mercury from other processing systems.Type: GrantFiled: October 10, 2018Date of Patent: March 29, 2022Assignee: ECOLAB USA INC.Inventors: Nicholas R.
