熔融結晶器缺點(diǎn)/Disadvantages

結晶器的結構相對精餾塔來(lái)說(shuō)，略復雜。需要發(fā)汗、洗滌等步驟。過(guò)程較復雜，過(guò)程的連續化較困難。
The structure of the mold is a little more complicated than that of the distillation column. It needs Sweating, washing, etc. The process is complex and difficult to be continuous.
相對于其它熱分離單元操作，熔融結晶具有如下優(yōu)點(diǎn)：
Compared with other heat separation units, melt crystallizer has the following advantages:
高選擇性、低能耗、操作溫度低、無(wú)溶劑、無(wú)廢液、無(wú)氣相。熔融結晶與精餾相?#23481;^，具有操作溫度低、所需能耗小等突出優(yōu)點(diǎn)。除以上兩點(diǎn)外，第三點(diǎn)就是可以利用工廠(chǎng)里其它操作單元所產(chǎn)生的廢熱。因為現有的大部分有機化合物的熔點(diǎn)都在工廠(chǎng)廢熱溫度范圍?#21462;?br /> High selectivity, low energy consumption, low operating temperature, no solvent, no waste liquid, no gas phase. Compared with distillation, it has many advantages, such as low operating temperature and small energy consumption. Besides, Waste heat from other operating units in the plant can be utilized. Because most of the organic compounds’ melting point is in the range of the waste heat in the factory.
熔融結晶與溶液結晶相?#23481;^，由于沒(méi)有添?#26377;?#30340;溶劑，所以避免了溶劑的后處理過(guò)程，這個(gè)優(yōu)點(diǎn)往往可以彌補熔融結晶的其它缺點(diǎn)。
Compared with solution crystallization, melt crystallization avoids the post treatment process of the solvent without adding new solvent, and this advantage can often compensate for other shortcomings of the melt crystallization.
熔融結晶處理的是液態(tài)物質(zhì)，液態(tài)相對于氣態(tài)而言，所需要的體積小，所用設備體積小，投資少。當然，如果熔融結晶需要長(cháng)的停留時(shí)間時(shí)，則這點(diǎn)優(yōu)勢就不明顯了。熔融結晶過(guò)程沒(méi)有氣體產(chǎn)生，泄露?#23376;?#25511;制。而且整個(gè)設備可密閉，有利于環(huán)境安全。熔融結晶不需要添加任何物質(zhì)，所以沒(méi)有廢液和其它化學(xué)物質(zhì)（溶劑）產(chǎn)生。要知道，溶劑回收的成本往往占整個(gè)結晶成本的大部分。對于非固體溶液型體系，從理論上來(lái)說(shuō)，結晶過(guò)程具有高的選擇性和高的產(chǎn)品純度。
Melt crystallizer deals with liquid substance, which requires a small size and a small amount of equipment, therefore needs less investment. However, if melting crystallization takes longer residence time, then this advantage is not obvious. During crystallization, no gas is produced, and leakage is easy to control. Moreover, the whole equipment can be closed and is more conducive to environmental safety. Molten crystallization does not require the addition of any substance, so no waste liquid or other chemical substance (solvent) is produced. The cost of solvent recovery often accounts for most of the cost of the crystallization process. For the non solid solution type system, the crystallization process has high selectivity and high product purity.
