RSR Corp.'s Quemetco Inc. selected the BOC LoTOx nitrogen oxide (NOx) control system to meet emissions requirements at its reverberatory furnace in City of Industry, Calif. BOC, Murray Hills, N.J., won the contract to install and operate the control system following a month-long demonstration at the City of Industry site. The demonstration, which was partly funded by the California Air Resources Board Innovative Clean Air Technologies program, used a BOC mobile demonstration trailer to treat a slipstream from the Quemetco furnace exhaust. Once installed, the full-scale system will enable Quemetco to meet California emissions limits without affecting its furnace operation.
