1. A treatment process for removing and/or remediating contaminants in a contaminated gas, comprising steps of:
flowing a stream of the contaminated gas through a pipeline;
treating the flowing stream of the contaminated gas by injecting droplets of an aqueous liquid treatment composition containing 35-55 wt % total of one or more hydroxide compounds into the flowing the stream of the contaminated gas in the pipeline such that the liquid treatment composition mixes into the contaminated gas in the flowing stream and remediates contaminants in the contaminated gas;
injecting water into the mixed flowing the stream of the contaminated gas and the liquid treatment composition in the pipeline downstream of where the liquid treatment composition is injected into the pipeline; and
separating the flowing stream of the treated contaminated gas from any remaining amount of the liquid treatment composition, the water and any precipitates and solids released from the contaminated gas in the treatment step in a separator.
