No. 6 means double jeopardy Oelker realized that a total system solution was needed, and sought the assistance of a U.S. company, Met-Pro Corp., Harleysville, Pa. Oelker noted that that plant managers were pleasantly surprised that one of their options involved using lower-cost fuel. “When we met with our client, they didn’t realize that they had an option for burning a cheaper fuel that normally would not enable compliance with all pollution control codes. We explained the solution to their problem and how they could burn No. 6 fuel oil with the proper environmental controls in place.” This involved a switch to No. 6 fuel oil and the installation of an environmental control system consisting of a dust collector and SO2 scrubber (see Figure 1). The system was the only one of its kind in Chile, and allowed the plant to burn No. 6 fuel oil in its manufacturing processes while still maintaining emission levels well within govern- The CMPC paper mill in Santiago, Chile uses low-cost No. 6 fuel oil to power its manufacturing processes, with environmental-control equipment from Met-Pro Corp. to control gaseous and particulate emissions within regulatory compliance. ment regulations (see Figure 2). The system also permitted operation without any loss in performance in their manufacturing operations, and with significantly lower operating costs than natural gas, while maintaining SO2 emissions at undetectable levels. The plant’s pollution control system incorporated a number of innovative technologies to achieve more efficient environmental compliance. For example, an option for the system’s pulse jet collectors made available the option of top bag removal, compared to the standard method of bottom bag removal.
