PROCESS DESCRIPTION

PROCESS DESCRIPTION In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000). The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)). The components of a contactor include a ...

A method for removing the blinding of calcium carbonate in a fuel gas desulfurizing process is provided to make it unnecessary to stop desulfurizing facilities temporarily, thereby reducing cost and time due to temporary stopping of the desulfurizing facilities, by using organic acid such as dibasic acid. When the blinding of calcium carbonate, in which a pH value of an absorption liquid is ...

NEUTRALISATION OF ACIDIC EFFLUENTS WITH LIMESTONE

its low cost. The price (1993) of limestone is only RIOO/t compared to R280/C for lime. The aim of this study was to develop a method whereby acid waters would be in contact with limestone to ensure effective neutralisation and efficient use of the limestone. A fluidised bed was proposed for this purpose. The bed is packed with small chips of ...

Experimental and modeling study of SO2 behavior during oxy ...

SO2 emissions from coal combustion have several harmful effects on the environment, including their contribution to acid rain. A variety of approaches have been developed to control SO2 pollution. Direct dry sorbent (limestone) injection is a relatively simple and low-cost process. Fluidized beds have been one of the most popular furnaces for the application of direct sorbent injection. In ...
