2020 CATALYST HANDBOOK INDUSTRY CATEGORIES PROCESS CATEGORIES COMPANY INDEX REFINING Emission control GAS PROCESSING Mercaptan removal DASH Application: Hydrocarbons and carbon monoxide (CO) from industrial emissions are a major cause of air pollution. The DASH catalyst fully oxidizes and decomposes these contaminants at low temperatures, and also recovers and makes effective use of the heat energy generated in the process of gas disposal. The DASH catalyst is useful for the prevention of air and odor pollution, the removal of volatile organic compounds (VOCs), for energy savings and for heat recovery. Economics: The DASH catalyst is cost-efficient because spent catalysts can be recovered and used. Description: The active surface areas necessary for the oxidative decomposition reaction are large, so they can effectively treat massive quantities of gas, even in relatively small amounts. Geometric surface areas of honeycomb catalysts are also large, so they can remove odors twice as effectively as sphere-type catalysts. Gas temperature is normally from 150°C-350°C at the time of processing of odor removal. Therefore, the fuel cost is half of that necessary for a direct combustion system. If the gas is concentrated, then the DASH catalyst produces self-sustained combustion. Contact: https://www.ne-chemcat.co.jp/eg/contact Supplier: N.E. ChemCat Corporation Website: https://www.ne-chemcat.co.jp/eg/business/chemical/ catalyst/environment.html Advantages: Many examples exist in which DASH catalysts have been used for more than 10 years. DASH catalysts have superior heat resistance and mechanical strength. They are also free of the effects of lower hydrogen sulfide content and halogen compounds. The DASH catalyst does not produce thermal NOx for oxidation removal. In addition, it does not need wastewater treatment because it is a gas phase reaction. Copyright © 2020 Gulf Energy Information.
