The feasibility of sintering red mud as wet desulphurization sorbent was studied in this paper. The comparative study of desulphurization efficiency by using sintering red mud and traditional desulphurization sorbent-limestone had done in Liquid-column impingement Scrubber apparatus. The effects of gas velocity, liquid-gas ratio and pH value on desulphurization efficiency were studied. Results show that the desulphurization efficiency of sintering red mud is lower than that of limestone in the same slurry mass concentration, while the sintering red mud can be used as desulphurization sorbent when increase its slurry solid content in appropriate way. The gas and droplets can mix well in absorption section when the gas velocity is upper than 2.7m/s. The desulphurization efficiency higher than 80% can be obtained when L/G ratio higher than 15L/m3 and the pH values between 5.2-7. © (2012) Trans Tech Publications, Switzerland.

A new algorithm which can detect the number of sources accurately in the case of a high degree of coherence and small difference between incident angles is proposed in this paper. The algorithm is based on the criterion of eigenvalue transformation of the covariance Matrix. Firstly, the output covariance matrix is decohered with toeplitz matrix, and then the number of coherent sources is estimated precisely through the appropriate threshold calculated by the new criterion of eigenvalue transformation. Simulations demonstrate the effectiveness of the algorithm. ©2010 IEEE.
