Belt filters of various sizes are also used for the clarification of phosphoric acid sludge as this process has shown to be economically beneficial. This paper discusses different aspects of belt filter applications in phosphoric acid processes, from both end user and supplier points of view. It is aimed at providing information to aid in the selection of future filters. This paper will re-examine the basic principles of economical heat transfer as it relates to these issues. An equilibrium reactor was developed taking into account the ionic species found in the urea synthesis conditions in such a way that it can operate as a synthesis reactor or a carbamate decomposer.
Results compare favorably against published data.
The model contains Technical Bulletins describing the validation of the predictions it generates. The plant consists of two stages - a single bed converter contact plant and a modified tower plant. SO 2 can be produced. This process does not generate any additional waste. To supply WMCF's fertilizer plant in Phosphate Hill a sulfuric acid plant was installed to treat the off-gases from the copper smelter in Mt. Isa.
