I have a question regarding the selection of condensers

2010-04-18View Original

Thread Content

For the distillation of solvents such as propanol, methanol, and ethanol, which type of condenser is preferable? It has been suggested to use a tubular design, with a 5000L reactor paired with two condensers of 12 square meters each, to achieve two-stage condensation; this approach would allow for the distillation of such solvents in one integrated system. Are there any other combinations possible? If a tubular type is chosen, is glass better or graphite better? It’s just that graphite condensers seem to be larger than those made of glass and take up more space

If a condenser with a small footprint is desired, the heat exchangers produced by Shandong Hongji Heat Exchange Technology Co., Ltd. can be considered; they offer high heat exchange efficiency and a compact size. Shenzhou Pharmaceutical uses such products.

Fainting – is there any more detailed information available? I’d like to know

If there are no size constraints, tube exchangers are recommended; glass condensers cannot be made large in size. Graphite is generally used in situations involving acidic materials or when carbon steel and stainless steel would be corroded

If the medium under such operating conditions is one of the conventional solvents listed, any stainless steel shell-and-tube heat exchanger will suffice. After all, the heat transfer coefficients of non-metals (such as graphite or glass) are much lower; unless you have specific requirements, such as the need for visual observation. . . . . As for the need for evaluation mentioned on the second floor, the equipment structure itself results in relatively large pressure drop losses; generally, the pressure at the flash outlet for solvent recovery is at a slight positive level. It is necessary to consider your specific process conditions to determine whether this approach is suitable.

Using a combination of shell-and-tube and spiral-plate heat exchangers

For fine chemicals, it is important to have the most suitable combination, as a single reactor is likely to produce several different products, and different solvents are used in each case; therefore, determining the optimal combination is of utmost importance

6# chen*an65: The spiral tube heat exchanger Heliflow from Graham Company in the United States is compact and can be installed in any location; it boasts a heat exchange efficiency of over 40%. Feel free to contact us via QQ: 1483891646, or by phone: 021-58819401
