Hello, I'm Robvanvee. I wanted to let you know that one or more of your recent contributions to Flue-gas desulfurization have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the help desk. Thanks.  Rob van  vee  11:43, 27 September 2019 (UTC)
