Problems in distillation column
In this article I would like to discuss the problems in distillation column. So basically, I am explaining the major problem in an easy manner which is generally faced in the chemical industries, like flooding entertainment of the solvent and the arrangement of the tray or plate in the distillation column . so many types of problems we have observed in the distillation column in this article I would like to explain in detail.
How we can change conditions like temperature pressure how distillation column effected what is the change in the refluxe ratio how can we overcome this problem
The majority of column-related issues you’ll run into are probably caused by inefficiencies, bottlenecks, and/or unforeseen shutdowns. These issues may have a negative effect on the plant as a whole, lowering output and yield. In order to tackle these challenges, new advancements in column internals are being studied, and existing technologies are being upgraded to help maximise their effectiveness and prolong the life of units. As a result, the mass transfer performance is not only more dependable but also more efficient from a financial standpoint.
problems in distillation column
problems in distillation column :- Column fouling can be brought on by a variety of variables acting alone or in concert. A column’s packing and other interior components are vulnerable to fouling because of the vaporisation of volatile compounds, droplet production from condensation, and chemical reactions that cause corrosion.
Mechanical Problems – Vibrations from the equipment might cause column parts to shift over time or even cause internal mechanisms to disassemble, damaging the internal structures.
Low vapour flow might result in a reduction in separation efficiency since it lowers internal pressure in the column. If the vapor’s pressure is insufficient, the liquid on the tray won’t be supported, allowing liquid to seep through the column’s internals.
Solution to avoid problems in distillation column
For both the client and the manufacturer of distillation equipment, technologies to address these problems and boost energy efficiency are at the forefront of column research and development. Due to the effort required to turn off the equipment, these issues can be highly expensive to address (often upstream and downstream equipment must be shut down as well since they are connected to the column). Some of the most current methods to help processors increase energy efficiency and dependability include:
Replacing traditional trays and packings with more modern, cutting-edge options – This can be accomplished in a number of ways, such as by installing high performance packing or by switching out random packing to improve efficiency and tower capacity. Process engineers have also begun combining various packaging sizes in.
New internal distillation column technologies seek to minimise fouling sensitivity, increase capacity, and reduce pressure drop. You can significantly lower capital expenses while increasing production by increasing the efficacy and dependability of distillation towers.

You can also request to contact with one of our sales engineers or download our Process Solutions for Mass and Thermal Media brochure if you’re interested in knowing more about our column capabilities.
Conclusion
The sole recommendation that should be made for the future is to try to concentrate on adjusting the feed inlet and reflux intake into the distillation column. The issue with our experiment was that we were unable to run it long enough to notice this pattern. The distillation experiment should be repeated in the future using steam pressures that are different from our values, and it could also be worthwhile to attempt and insulate the distillation column and reboiler.
