Molecular Distillation System

Molecular Distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation.

Product Features

Design

Different from the traditional wiped film evaporator design, the condenser is located inside the short path evaporator body.

Operation 

Feed liquid is admitted into still under high vacuum, immediately spread into a very thin film and forced quickly down the evaporation surface. Heated walls and high vacuum drive the more volatile components (distillate) to the external condenser as the less volatile components (residue) continue down the cylinder. The resulting fractions, thus separated, exit through individual discharge outlets. Depending on application, the desired product is either the distillate or the residue fraction. Small amounts of condensable low MW compounds collect in cold trap upstream of vacuum system. For high solvent loads, an optional external condenser may be installed immediately downstream of the still.

Particular features

Continuous distillation process.

Very low operating pressures up to 0.1Pa (100Pa=1mba). (The considerably lower pressure in the short path evaporator is obtained by the short distance for the vapours on their way from the evaporator surface to the condenser. )

The very low operating pressures ensure very low distillation temperatures and therefore a very gentle distillation is possible.

Short residence time. (Thanks to the short residence time, the low evaporation temperature and the immediate cooling of the concentrate, thermal stress and decomposition of the product can be minimized.)

High evaporation rates.

——Fields of application 

For the thermal separation of high molecular and high-boiling products.

For heat sensitive materials.

Sanitary grade of SUS304/SUS316L Stainless Steel Vendor: Shanghai Bao Steel Group Corporation or equivalent supplier.

In order to keep the raw materials organized and make sure proper material will be used, we insist asking the material vendor to provide original material test report. Also, we will do in-coming tests to ensure the material is qualified:

  • Metal spectrum analyzer
  • Thickness gauge
  • Roughness detector

All designing, manufacturing and inspection processes are performed according to GB150-1998. ISO9001 Quality Management System Standard will also be applied throughout the entire manufacture process.

Yes, with our certified workshop and excellent welding technics, we can provide you with high quality ASME or PED pressurized equipment.

As multiple tests and inspections are required, lead time of such equipment is longer than normal pressure equipment, it usually takes 18 to 20 weeks to finish.

Plasma welding machine imported from Germany will be used for tank longitude and girth welding and fillet welding to make sure the welding seam smooth and even.

Also, GTAW welding technology will be applied, inert gas concentration is 99.999%. Different welding wire ER316L or ER308 will be applied for different material of SS plate.

For particular circumstances, electric-arc welding will be applied. Welding material used for:

S304-S304: A102; S316L-S316L: A022; Different SS: A302.

Welding seam between jacket and vessel shall be NDT inspected according to JB4730-94 to ensure the impermeability and long service life.

For single tank, it takes around 3-5 weeks to deliver.

For integrated systems, it normally takes 18 to 20 weeks to deliver.

ASME/PED certified equipment will take 18 to 20 weeks

You are welcome to contact us for details if any needs.

Yes, customization order is acceptable.

You may send over the requirements, we will realize your design and provide you with the most cost-efficiency solutions.

Plastic wrap film should be applied around the entire equipment.

Electrical parts should be disassembled and packed in crates if possible, otherwise it should be fully protected from water or any kind of potential damage in shipping.

Tank will be put down and sitting on a CS frame support, steel wire will be used for fasten tank to support. Rubber should be applied to where steel wire is touching the equipment.

When fixing the equipment in container, multiple fixing belts and/or steel wires should be used to make sure no movement of equipment.

should be used to make sure no movement of equipment

Yes, we will.

Equipment will be thoroughly washed before packing. Water used for washing should not have chloridion content more than 25mg/L to avoid damage of stainless-steel surface. Water stains must be cleaned once washing is finished.

Normally we will ship the equipment by sea due to the weight of it.

Air shipping is also an option, but it will cost more.

It depends on your choice.
