Direct cooling crystallization |
| abstract |
A crystallization process is improved by employing direct contact cooling whereby a volatile liquid is vaporized to provide the cooling necessary to effect the crystallization. The effluent vapors of the volatile liquid may be liquified and recycled for reuse by manipulation of temperature and/or pressure. In one embodiment, durene is crystallized from a C 10 + aromatics fraction using liquified n-butane as the coolant. |
