Hog Dryer Study

PE Tech completed a study to determine the feasibility of using electric energy to run a hog dryer and create efficiencies in their operating conditions and utilize their boilers more effectively to support efficient electrification. The purpose of this project was to identify GHG emission saving opportunities by reducing natural gas usage on the dual fuel power boiler through biomass mechanical dewatering. As part of this study, the team developed a baseline using existing process data and then using manufacturer specification data, they determined what a new operating scenario would be for different bed dryer technologies. PE Tech analyzed five different options including innovative technologies not yet used in the pulp and paper industry. The project recognized the opportunity to significantly reduce GHG emissions through generating more steam from biofuel and displacing natural gas consumption.   All updates were validated against the existing hog press specifications to ensure each studied process supported consistent moisture content into the new biomass dryer. PE Tech completed this project by providing the client with a report summarizing risks, preliminary layout drawings, new operating costs, and a capital cost estimate for the recommended technology which would reduce GHG emissions at their facility.
