Product Introduction
Extraction and azeotropic distillation device (glass/stainless steel)
definition:
A third component (called extractant or solvent) is added to the raw material liquid to change the relative volatility between the original components to obtain separation. Different from azeotropic distillation, the extractant does not form azeotropes with any components in the raw material liquid.
The operating characteristics of extractive distillation: In order to increase the relative volatility of the separated components, the liquid phase of each plate should maintain sufficient additive concentration. When the raw material and extraction solvent are added to the column in a certain proportion, there must be a certain maximum Appropriate reflux ratio. When the reflux without additives is too large, instead of improving the composition of the distillate, it will reduce the concentration of additives in the column and make separation more difficult. Similarly, when the reflux temperature at the top of the tower is too low or the temperature at which the additive is added is low, it will cause partial condensation of the steam in the tower and dilute the concentration of the additive in each plate.
In the design, in order to make the concentration of the additives in the rectification section and the stripping section roughly close, the feed liquid of the extractive distillation is often fed into the column under the thermal condition of saturated steam. If it is bubble point feeding, the concentration of additives in the rectification section and the stripping section are different, and different phase equilibrium data should be used for calculation.
product description:
The extractive distillation experimental device is mainly used for laboratory small test and pilot test research and development and simulation. The small test continuous device is mainly made of glass material, which is convenient for observation during the experiment, and the normal pressure/decompression operating conditions can meet the requirements. , but the glass device is not pressure-resistant and the equipment is easily damaged, so the small test device can also be made of stainless steel; the pilot plant is made of stainless steel due to the larger processing capacity.
The main part of the equipment is composed of raw material tank, extractant tank, preheater, tower kettle reboiler, rectification tower, condenser, reflux ratio/reflux tank, tower top receiving tank, tower bottom receiving tank, feed pump, tower Top production pump, tower still production pump, valves and pipelines, control system, vacuum system and other important parts, this system can operate under normal pressure or decompression, and the sealing requirements of the whole set of equipment are relatively high during decompression operation , During the experimental operation, pressure fluctuations will affect the stability of the entire experiment, so the connection parts of the system equipment are all flanged and sealed with PTFE gaskets.
The control system of this device adopts PLC integrated control, and the automatic control system can realize the precise control and system stability of pressure, temperature and flow by viewing the process interface, browsing and viewing the stored historical process data, and accessing the curves of various process parameters. The key protection system ensures the safety of the device and operators through some safety interlocking designs.
The design goal is to build a high-quality and high-level test device skid-mounted platform for customers. The overall level of the device requires a high degree of automation, good data accuracy and repeatability, easy operation, safety and reliability, and long-term stable operation.
