Problems with the boiling and crystallization of vinyl carbonate
Thread Content
During the operation of the device, unfamiliarity with the new process led to the following two issues when handling refined carbon ethyl: 1. Boiling, which caused most of the material to be carried away by the steam, resulting in significant losses. 2. Crystallization: Excessively low temperature control causes crystallization to occur inside the film evaporator, leading to blockages. How can the above phenomena be controlled using the instruments without observing through a viewfinder?
I personally think it’s a mismatch between your operating conditions and the structure. The space available for vapor-liquid separation is insufficient, and the upward gas velocity is too high; an additional demister can be added. Crystallization on the inner surface of the falling film crystallizer occurs due to an excessively fast evaporation rate, and reducing the pumping speed is likely to yield better results.
