Reaction calorimetry provides information quickly which can be applied to quantify the risks and criticality associated with a chemical process. Reaction calorimetry helps identify key process parameters, including: Continue reading →
I would like to thank the American Institute of Chemical Engineers (AIChE) and William Hollar (Sabic) for inviting METTLER TOLEDO to present a paper at AIChE Spring 2013 Session in San Antonio last week. The session – New Approaches in Chemical Manufacturing Operations – Continue reading →
I’m really looking forward to attending the annual American Institute of Chemical Engineers (AIChE) meeting in Pittsburgh, PA this year. It is always a great opportunity to meet excellent scientists working in very diverse areas. As a chemical engineer it is also nice to focus on chemical engineering for a change! – since many of the conferences I attend are chemistry orientated.
The starting point for most crystallization processes is a saturated solution. Crystallization is generally achieved by reducing the solubility of the product in this solution by cooling, antisolvent addition, evaporation* or some combination of these methods. Another common method used to drive crystallization is via a chemical reaction where two or more reactants are mixed to form a solid product insoluble in the reaction mixture; a common example of this would be the reaction of an acid and a base to form a salt.

Crystallization touches every aspect of our lives from the foods we eat and the medicines we take, to the fuels we use to power our communities. The majority of pharmaceutical products go through at least one crystallization step during their manufacture. Salt and sugar are delivered to our dinner tables as crystals. The unwanted crystallization of gas hydrates played a role in the recent Deepwater Horizon oil spill. Continue reading →
