For the spray tower limestone process to achieve a specified SO2 removal effi- ciency, it is more economical to increase the limestone stoichiometry and mini- mize the absorber liquid/gas ratio (L/G). The use of adipic acid or possibly dibasic acid (DBA) as an additive to enhance SO2 removal in the limestone scrubbing process is an economically ...

Limestone. Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - CaCO 3 ). There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral ...
