20090159257 | METHOD AND SYSTEM FOR REGULATING A CONTINUOUS CRYSTALLIZATION PROCESS - A process and a system for regulating a continuous crystallization process which can be used especially for preparation of bisphenol A comprises a heat exchanger connected in a circuit to a crystallization apparatus. A heat exchange performance of the heat exchanger to cool an exit stream of the crystallization apparatus is established as a function of a feed stream supplied, in order to deliver by regulation an exit temperature of the exit stream. The heat exchange performance is calculated, and the calculated heat exchange performance is established in the heat exchanger with a time delay. The time delay prevents large temperature differences in the heat exchanger, so as to prevent fouling in the heat exchanger. With improved regulation quality, this leads to fewer production shutdowns and hence to improved productivity. | 06-25-2009 |

20110105735 | METHODS OF PRODUCING AND PURIFYING PROTEINS - Methods of producing and purifying proteins that comprise a glycan tag are provided. In some embodiments, a protein may be modified to include a glycan tag so as to facilitate production of the protein, e.g., by promoting protein secretion and/or promoting protein solubility. In some embodiments, the present disclosure provides methods wherein a protein may be modified to include a glycan tag, which may then be used as an affinity tag for purification. | 05-05-2011 |
