Newton Chambers A process for purifying benzene by fractional solidification cooling is accomphshed by mixing it with refrigerated brine. The process does not remove thiophene. 

This method applies to only two aromatics, benzene (mp - 5.55 0 and jp-xylene (mp = 13.5°Q. Crystallization is of undeniable economic value for the treatment of high benzene cuts (coal benzols and pyrolysis C6 cut). However, this process, developed by Newton Chambers, has hitherto been used only for coal benzols. 

Momentum, thermal and mass transports are three basic physical phenomena of any fluid flow. In a CVD process, when the precursor gases enter a high temperature reaction chamber from room temperature, the aforementioned three transports occur under certain velocity, temperature and concentration gradients. The common underlying physical laws for these three transports are all based on a molecule s thermal motion. Three specific underlying laws which describe the three transports are Newton s viscous law, Fourier law and Fick s law respectively. For a simple one-dimensional system, these laws can be expressed by [14]...
