Economic comparison of emission control systems for glass manufacturing furnaces with heat recovery.

Glass manufacturing, like other process industries, is faced with air pollution compliance problems due to ever stricter emission limits. Several waste gas cleaning equipment options are available for air pollution control (APC) in glass plants, the most common arrangements being based on electrostatic precipitator (ESP) or fabric filter (FF) dust collectors and semi-wet or dry processes for acid gas removal. However, several counteracting aspects affect the choice of gas cleaning technologies, which are confirmed by the discrepancies encountered in actual suppliers' bids.

Waste-to-energy plant for paper industry sludges disposal: technical-economic study.

In this work, a detailed technical-economic analysis of a fluidized bed based waste-to-energy system for disposal of paper manufacturing sludges has been carried out. Specific reference is made to a case study represented by the largest plant in Italy producing recycled paper, with a daily sludge output of about 52t. The adopted plant has been sized for a nominal capacity of 140t per day also allowing the progressive elimination of sludges accumulated in a previously utilized landfill, giving a nominal electrical power output of 3.

Cost-Effectiveness Analysis of Waste Gas Treatment Plants for the Glass Industry.

Cost-effectiveness of different plant solutions for glass furnace waste gas cleaning is compared in the present paper. Plant arrangements based on electrostatic precipi-tator or fabric filter dust collectors and wet, semi-dry, or dry processes for acid gas removal have been considered. A critical survey of each solution's advantages and disadvantages has been presented, taking into account both effectiveness and costs resulting from each available system.

Polyfunctional Plants for Industrial Waste Disposal-Part I: Process and Equipment Design.

This article is the first of two papers dealing with development of a design and costing procedure for polyfunctional waste treatment plants. Part I reviews equipment sizing aspects. Part II defines and validates the cost estimation procedure.

Polyfunctional Plants for Industrial Waste Disposal-Part II: Economics and Model Evaluation.

This is the second part of a two-part paper dealing with the preliminary design and costing of polyfunctional waste treatment plants. In this article, we present some criteria for estimating capital investment and annual operating costs of polyfunctional plants for industrial waste treatment. The process and equipment design methods presented in Part I of this article, together with the economic approach proposed here, allow for complete technical/economic analyses.
