Beiyang Lixing Stainless Steel Distillation Tower Instrument Extraction Tower Distillation

Stainless steel distillation tower is a chemical equipment used for separating liquid mixtures, widely used in laboratories, industrial production and other fields. The following is comprehensive information about stainless steel distillation tower instruments:

1. ‌Equipment structure and function‌

• ‌main componentsIncluding tower kettle, reboiler, condenser, reflux ratio controller, etc. The tower kettle is used to heat raw materials, the condenser is used to cool steam, and the reflux ratio controller adjusts the reflux ratio to improve separation efficiency

• ‌materialUsually made of 304 or 316L stainless steel, it has strong corrosion resistance and is suitable for separating organic solvents such as ethanol and methanol

2. ‌Application scenarios‌

• ‌Laboratory useUsed for teaching and scientific research, such as the separation of petroleum fractions, alcohols, ethers, and volatile oils from traditional Chinese medicine

• ‌industrial productionSuitable for alcohol recovery, solvent purification, etc., such as distillation recovery of ethanol and methanol

3. ‌Operation precautions‌

• ‌Installation key pointsEnsure the verticality and concentricity of glass components (such as distillation heads) to avoid breakage caused by improper clamping

• ‌Experimental ProcedureIncluding starting the centrifugal pump for feeding, introducing condensate water, taking samples and measuring density after stabilizing the temperature, etc

Extraction tower is a key equipment used for liquid-liquid or gas-liquid mass transfer in chemical separation processes, and its core function is to achieve selective transfer of target components through two-phase contact. The following are the main technical characteristics and application scenarios of extraction towers:

1. ‌Structure and Type‌

• ‌packed columnCommon stainless steel materials (such as 304/316L) are equipped with fillers such as step rings and ball rings to increase the mass transfer area, suitable for laboratory or small and medium-sized production

• ‌Sieve tray towerThe tray aperture is 2mm, arranged in a triangular shape, and the overflow pipe is designed to control the liquid flow. It is commonly used for distillation separation of ethanol water and other systems.

• ‌Supergravity bedRotating structure enhances mass transfer through centrifugal force, suitable for rapid separation of high viscosity or thermosensitive materials

2. ‌operating parameters‌

• ‌temperature controlThe condenser at the top of the tower needs to be filled with cooling water (the flow rate is adjusted by a rotor flowmeter) to prevent steam from spraying out; The heating power of the tower kettle is usually controlled at 3-4A current.

• ‌pressure monitoringThe pressure inside the kettle is monitored in real-time by a pressure indicator to prevent liquid flooding (the heating current needs to be reduced when the pressure suddenly increases).

• ‌reflux ratioBy adjusting the reflux ratio controller, the separation efficiency is affected. During the experiment, samples need to be taken after the temperature at the top and bottom of the tower is stable

3. ‌Application scenarios‌

• ‌Alcohol recoveryStainless steel distillation tower is used for the purification of ethanol water mixture, with a tray efficiency of 0.75~0.85 and equipment investment 40% lower than that of float valve tower.

• ‌Essential oil extractionThe water vapor distillation of plant essential oils such as rosemary and agarwood requires a condenser and extraction tank, and some equipment integrates pressure reduction function to improve the recovery rate of volatile components

• ‌Laboratory scaleGlass distillation tower (electrically heated or vacuum insulated) is suitable for small-scale experiments, such as vacuum distillation of high-purity solvents

4. ‌Selection and maintenance‌

• ‌Material Selection316L stainless steel is preferred for corrosive materials, while 304 material can be used for ordinary working conditions

• ‌Fault handlingIf boiling occurs (liquid rushes out of the top of the tower), the power should be immediately cut off and the material should be refilled to the specified liquid level.
