Controls for glass melters may save trillions of Btu/yr

Article Abstract:

Air Products and Chemicals is developing an expert system that can optimize the performance of oxy-fuel melters, which could potentially lower energy used during glass production by as much as 15 trillion Btu/yr. The glass industry is currently using simple linear systems during the manufacture of glass but wastes a lot of time in trial-and-error attempts to reach steady-state operation. The expert system offers a system of automatic controls allowing glass melters to optimize quality and operate more efficiently.

Pick the best acid-gas emission controls for your plant

Article Abstract:

Wet limestone, wet soda ash or caustic soda, lime spray drying, circulating lime reactor and sodium bicarbonate or sesquicarbonate injection are some of the methods used in controlling acid-gas emissions from chemical facilities. The selection of the best emission control can only be determined after considering capital and operating costs; operability and maintainability; and site-specific preferences for reagent form.

Right-sizing environmental controls

Article Abstract:

Details of the case studies that reveal bigger environmental control systems may not always be environmentally or economically viable are presented. Examples that emphasize the importance of right size of pollution control systems for stable environmental conditions are discussed.
