Purge strategy

SIDE DRAW WITH A PRACTICAL AUTOMATIC PURGING STRATEGY... 

Since the flowrate of the side stream is quite small, an alternative way to periodically purge out this impurity is also purposed. This automatic purging strategy does not rely on any online composition measurement but only uses a temperature measurement. Qosed-loop dynamic simulation demonstrates that the proposed purging strategy can successfully keep the column under normal operation with both product purities at their specifications despite feed impurity variations. 

Potential Enzyme-Related Impurities and Purge Strategies... 

Eaeh reservoir eompartment should be provided with two three-quarter-ineh minimum size plugged eonneetions above the rundown oil level. These eonneetions may be used for sueh serviees as purge gas, makeup, oil supply, and elarifier return. One eonneetion should be strategieally loeated to ensure an effeetive sweep of purge gas toward the vents. 

This chapter introduces the principles, methods and strategies for the composition of formulas that stimulate the intestines, promote bowel movement in order to purge accumulation, eliminate toxic substances, drain fire and cold of the body and drive out congested water. They are used to treat excess conditions and interior syndromes. These methods and strategies relieve the symptoms rather than treat the cause. However, they can stop further pathological changes caused by the accumulations. 

In this way, it assists herbs that purge and drain downwards and herbs that descend Qi in the intestines. For applying this strategy, Jie Geng should be used in small dosage. 

The strategy of the formula composition is to use seeds, honey and Yin-nourishing herbs to moderate the function of the purgative and Qi-activating herbs. 

This formula demonstrates the strategies of clearing the heat. It not only reduces the heat by cooling and descending, but also by purging the bowel, increasing urination and dispersing the Qi and heat in order to separate and remove the heat. In this way the heat can be eliminated completely. 

In this formula, a strategy is used to drain heat-toxin and eliminate the intense heat in the Heart by purging the intestines and promoting bowel movement. 

This reaction is difficult to avoid, but it can be minimized by working with these melts at the lowest practical temperature. Some authors suggest purging the melt with 02 or N02 in order to oxidize the N02 to NOj, but these procedures may lead to the production of still more impurities such as hydroxide, superoxide, and hydrogen ion [39]. By far, the best strategy is to use the highest quality starting materials available and to subject these materials to careful recrystallization before...
