This document reports on an evaluation of emissions from, and available control technology for, submerged combustion evaporators used by the potash industry in New Mexico. A review of the operating parameters of the evaporators was made and the limited existing emission data evaluated. A field measurement program was conducted which utilized a SASS sampling train to quantify the particulate emissions and particle size distribution. Although the submerged evaporator emission proved to be a difficult source to sample because of high moisture content, high particulate concentration and very small particle size, data were obtained that allowed an evaluation of the technical and economic feasibility of control technologies. The three control options that are discussed include a Brink mist eliminator, a Venturi scrubber and a multiple effect evaporator.
