Ionization systems configured with a catalyst-bearing sleeve provide improved filtration while keeping ozone levels within acceptable limits. Modular configurations provide for serviceability and replaceability. System controls monitor particulates, temperature, humidity, and other relevant factors and adjust an ionization level accordingly for optimal performance.

Systems and methods for controlling an amine contactor are provided. An exemplary method includes determining a pickup ratio for a solvent in the contactor, measuring a temperature of a lower tray of the contactor, adjusting the pickup ratio based, at least in part, on the temperature, and adjusting a flow rate for an injection of lean solvent into the contactor based, at least in part, on the pickup ratio.

One aspect of the invention relates to a method comprising a single-stage conversion of an atmospheric pollutant, such as NO, NO.sub.2 and/or SO.sub.x in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO.sub.2.sup.0), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

A carbon dioxide capture process system includes an absorber vessel, a stripper, a first group of sensors and a second group[ of sensors. The first group of sensors is adapted for collecting real-time temperature, pH, density and viscosity data for a lean carbon capture solvent used for carbon capture from an acid gas adjacent the lean carbon capture solvent inlet. The second group of sensors is adapted for collecting real-time temperature, pH, density and viscosity data for a rich carbon capture solvent following carbon capture from the acid gas adjacent the rich carbon capture solvent inlet. A control system and related method are also described.
