Crystal engineering is applied when the crystal size distribution is too large to meet downstream specifications. By designing the crystallization to produce a fine crystal distribution in situ, downstream milling operations are avoided, thus improving the yield, and reducing energy consumption or safety hazards which may arise due to milling.

Crystallization is a critical process for the purification and isolation of chemical compounds in the manufacture of many fine chemical and pharmaceutical products. The results of the crystallization step have far reaching impacts on overall process efficiency and final product quality. Crystallization is also a very difficult process to effectively optimize and control. Crystallization is inherently complicated simply by being a process involving the creation and formation of solid particles.
Timothy A. Bell, of DuPont Engineering Research and Technology, wrote a review of the challenges of scaling-up particulate processes where he stated: Continue reading
