Should You Use a Filter or a Centrifuge? Follow a simple procedure to make the correct choice

摘要

YOUR COMPANY has developed a new product and now it's time to go from the laboratory to small-scale production.Your chemists have created a slurry and have separated the product most likely using laboratory filters or maybe a laboratory centrifuge.These units are great for demonstrating the effectiveness of the new product.However,they may not produce the same product quality in full-scale operation.So,it's sensible to take several steps before firming up the process flow diagram(PFD)and making equipment selections.The chemists likely have provided you with all the most common fundamental data such as particle size,density and other physical properties of the slurry.(Don't just view the researchers as a source of data;they also sometimes can offer valuable insights for your scale-up efforts-see:”Talk to a Chemist,”http://bit.ly/30puZcK.)You may want to consider refining the product through a variety of drying methods or even liquid/liquid extraction,especially if the desired material is a liquid.However,the most common choice for separation usually involves either filtration or centrifugation.
