Identification of thermal error in a feed system based on multi-class LS-SVM

Chao JIN, Bo WU, Youmin HU, Yao CHENG

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 1,   Pages 47-54 doi: 10.1007/s11465-012-0307-6

Abstract:

Research of thermal characteristics has been a key issue in the development of high-speed feed systemsystem is identified with the variance and mean square value of the temperatures of supporting bearingsA series of experiments were carried out on a self-made quasi high-speed feed system experimental benchThe results show that the recommended model can be used to predict the thermal error of a feed systemsystem.

FBRM and PVM investigations of the double feed semi-batch crystallization of 6-aminopenicillanic acid

Min SU, Lin WANG, Hua SUN, Jingkang WANG

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 3,   Pages 282-288 doi: 10.1007/s11705-009-0018-7

Abstract: 6-Aminopenicillanic acid (6-APA) is a crucial pharmaceutical intermediate in the chemistry of semi-synthetic antibiotics. The focused beam reflectance measurement (FBRM) technology and particle vision measurement (PVM) technology were employed to the processes of online-monitoring of 6-APA crystallization behavior in a double-feeding semi-batch crystallizer. Experiments were carried out with four kinds of double-feeding policies and the results were compared with the traditional single-feeding. Records and analysis of FBRM indicated that the nucleation of double feeding policy was much higher than single policy, and chord length of 6-APA was almost determined and had little change after the nucleation peak. Ostwald ripening process had no significant effect on further growth of 6-APA crystal. PVM images showed that the crystal habit of 6-APA was continuously changed during the crystallization process. The development of (002) face in the final crystal for the five feeding policies were different.
