The Degree of Desulphurization of a Limestone/Gypsum Wet FGD Spray Tower using Response Surface Methodology

2007

The degree of desulphurization was studied using response surface methodology (RSM), which enables effect examinations of parameters with a moderate number of experiments. All experiments were conducted in a lab-scale spray tower for limestone/gypsum wet flue gas desulphurization (FGD). The model flue gas was prepared from air and SO 2 gas. The SO 2 concentrations in the gas phase were determined by a multi-method analyzer. The degree of desulphurization correlated well with operating parameters, including pH, L/G, T, and v, with a determination coefficient R-Sq of 0.964. Effect tests indicate that L/G has the most significant influence on the degree of desulphurization. The interactions of L/G with pH, and with v, both play important roles. The result indicates that the evolutive response surface model is helpful to describe the degree of desulphurization of the limestone/gypsum wet FGD spray tower.

BACKGROUND: Wet FGD technologies account for around 87% of such systems worldwide, particularly those that use limestone as the absorbent. This technique is widely used in large thermal power stations. Limestone reactivity is one of the parameters that most influence the yield of the FGD process. With the aim of improving the design and operation of desulfurization units, many studies have been carried out to investigate the rate of limestone dissolution.
