What tower equipment is needed! ! ! !
Thread Content
I have a mixture with three components, accounting for 60%, 20%, and 10% respectively, with boiling points of 68 degrees, 98 degrees, and 80 degrees. The first two components are desired, while the third one is not wanted. There are also 10% of substances with low and high boiling points, which are all undesirable. If 2 tons of such mixture need to be processed per day, how should the distillation tower be designed? This post was last edited by ddc805 on 2009-3-30 09:47]
I guess two towers will be needed; without property data, it’s hard to say
I would appreciate some advice from those with experience regarding the approximate height of the tower, its diameter, and the size of the distillation vessel, etc.
Especially, manufacturers of distillation columns, please give some advice! ! !
Laboratories and engineering fields have their own approaches; if you want to know in detail, it’s best to provide the operating conditions and relevant parameters. Only in this way can I help you better. What tower manufacturers produce may not be suitable.
Here’s the situation: There is a product that I want to develop, but I haven’t decided where to start; it depends on the costs. The factor mentioned above is one of the criteria for making such a decision – whether the raw materials should be distilled from mixtures or purchased directly.
If you have sufficient capacity in your utility facilities, distillation from a mixture is generally cheaper. Of course, it depends mainly on the volume and production cycle; if the timeline is short and considering the added value of the product, investing in equipment may not be cost-effective. To determine whether an economy is healthy or not, one must consider it as a whole. It can’t be considered in isolation. (If you’d like to discuss further, you can send me a message.) )
Please provide the detailed parameters so that I can help you with the calculation! A tower definitely won’t work!
The volume of products processed is relatively large, ranging from 200 to 700 tons per year. The material obtained through distillation serves as the raw material, and after 6 steps of reaction, the final product is produced. The price of this final product is 400,000 yuan per ton, so its added value must be quite high. The problem lies in the distillation of the raw materials: there are three components, two of which are needed while one is not.
One tower definitely won’t suffice; at least two are needed, and possibly three as well, with an intermediate tank in addition. The diameter and height of the towers depend on the volume to be processed and on the type of packing used. If the volume is between 200 and 700 per year, the towers won’t need to be very large. It’s just that items costing 400,000 per ton are not very common these days, so one should be cautious. If the pollution is high, I still advise you not to do it. Hehehe
Due to technical and commercial secrets, I can’t go into too much detail. Thanks for the reminder from above – pollution does exist, and this is already within our consideration; addressing it is of course a priority. What I need to decide now is whether to start by using the raw materials directly (whose price is certainly higher) or to distill the raw materials myself; I need to find a balance to determine where the highest economic efficiency can be achieved! ! !
Your product should belong to the category of small-scale fine chemical products; although their added value is high, the production volume is low. The diameter of the distillation column is likely to be very small, ranging from 200 to 400. If a very high level of purity is required, multiple stages of distillation – or what’s known as secondary distillation – are necessary. For high-quality products, four columns might be needed. It’s best to work with relevant design firms or research institutes to develop and design such systems, as investing in such high-value products requires significant capital, and efforts must not go to waste.
It can be simulated using chemical engineering software, such as ASPEN
