摘要： 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.

摘要： Methods for facilitating the removal of mercury from flue gases by converting elemental mercury to oxidized mercury and subsequently capturing the oxidized mercury. In one aspect, a method of removing mercury from a mercury-containing flue gas may include the steps of introducing into the flue gas a sulfide source in an effective amount to convert elemental mercury to gaseous oxidized mercury and then capturing the gaseous oxidized mercury.
