Description:Metal casting operations produce air streams containing 0.5 to 5 volume percent of various catalyst vapors. The source of these streams is the exhaust from cold box core machines. These streams are a serious pollution problem and are produced at 3,000 U.S. foundries. They also are a significant resource recovery opportunity because a large foundry may release catalyst vapors with a potential annual value of $200,000 to $500,000. The overall objective of this project is to develop a membrane process to recover and recycle the catalyst vapors. In favorable cases, the process can achieve simple payback times from the value of the recovered catalyst of 1 to 2 years. The focus of the Phase I research is to develop a suitable membrane for the process and to analyze the technical and economic feasibility of the process based on the membrane properties determined by permeation experiments with air/catalyst vapor feed gases.
If successfully developed, the process will be applied widely because current technology involves destruction of the catalyst vapors at a significant cost to plant operators. Initial users are likely to be foundries operating on a continuous basis, in which significant amounts of catalyst could be recovered from a single machine. There are about 400 to 500 such large foundries in the United States and more overseas. The potential market in the United States is $90 million in these larger plants, with an industry-wide market of $200 to $300 million.
