Manufacture of ammonium sulfate fertilizer from FGD-gypsum. Quarterly report, 1 December 1994--28 February 1995

PDF Version Also Available for Download.

Description

The overall goal of this project is to assess the technical and economic feasibility for producing feasibility-grade ammonium sulfate from gypsum produced as part of limestone flue gas desulfurization (FGD) processes. This is a cooperative effort among the ISGS, the UIUC, AlliedSignal, SE-ME, Henry Fertilizer, Illinois Power Co. (IP), and Central Illinois Public Services (CIPS). Bench-scale experiments will be conducted to obtain process engineering data for the manufacture of ammonium sulfate from FGD-gypsum and to help evaluate technical and economic feasibility of the process. Controlled greenhouse experiments will be conducted at UIUC to evaluate the chemical impact of coal-derived impurities ... continued below

Description

The overall goal of this project is to assess the technical and economic feasibility for producing feasibility-grade ammonium sulfate from gypsum produced as part of limestone flue gas desulfurization (FGD) processes. This is a cooperative effort among the ISGS, the UIUC, AlliedSignal, SE-ME, Henry Fertilizer, Illinois Power Co. (IP), and Central Illinois Public Services (CIPS). Bench-scale experiments will be conducted to obtain process engineering data for the manufacture of ammonium sulfate from FGD-gypsum and to help evaluate technical and economic feasibility of the process. Controlled greenhouse experiments will be conducted at UIUC to evaluate the chemical impact of coal-derived impurities in ammonium sulfate produced from FGD-gypsum on soil properties. A process flow sheet will be proposed and market demand for the products will be established. An engineering team at IP will provide an independent review of the economics of the process. AlliedSignal will be involved in testing and quality evaluation of ammonium sulfate samples and is interested in an agreement to market the finished product. CIPS will provide technical assistance and samples of FGD -gypsum for the project. In this quarter, with an exception of the neutron activation analysis, analyses of FGD-gypsum samples that were generated by two power stations were completed. The high quality FGD-gypsum sample produced from the Abbott power plant in Champaign, IL was 98.36% gypsum, CaSO{sub 4}{center_dot}2H{sub 2}O, and less than 0.01% calcium`` sulfite, CaSO{sub 3}. The low quality sample from CIPS`s Newton Power Plant at Jasper, Illinois, was only 7.36% of gypsum. It was 87.54% calcium sulfite. A literature search provided the information to set up a batch, bench-scale reactor system. Reactions were conducted at 70{degrees}C for a range of times which resulted in 82% conversion of calcium sulfate to ammonium sulfate.
