Distillation and rectification

Distillation technology is commonly used in the Chemical, Pharmaceutical, Food and Beverage, and Environmental Technology industries. We provide you of any shape and size distillation plants for the separation of compound mixtures, for gas stripping and for the recovery and cleaning of solvents. Thus, we offer column system: Random packing columns;Structured packing columns;

Sieve tray columns.

Internals

Different inserts we chosen presented as follows are used depend on the application of the columns.

Reboiler

The falling film evaporator as reboiler supports rapid start-up and shut-down of the column due to its limited liquid holding capacity. It is easy to control and suitable to operate with the smallest temperature differences. Falling film reboilers are used for temperature-sensitive products and are particularly suited to energy saving, multiple-effect distillation processes. Falling film reboilers are used for temperature-sensitive products and are particularly suited to energy saving, multiple-effect distillation processes.

Forced circulation reboilers are used for reboiler which fed with viscous or heavily contaminated media .High liquid velocity in the tubes and the shearing force ensures that this kind of heat exchanger is operated within its optimum performance range, while keeping fouling to a minimum. What pump you select influences performance and efficiency.

Fields of application

Alternative Fuels
Production of bioethanol as a fuel additive
Dehydration of ethanol by means of molecular sieves or entrainer distillation

Shanghai Dea chemical equipment Co.,Ltd

——We devote to design and develop the equipment of chemical separation and abstraction.

——We came from East China University of Science and Technology, which we long-term cooperated with later. And now, we serve for many famous universities, such as Tsinghua University , Sun Yat-sen University , etc.

——We provide equipment of distillation and extraction for the technicians in the area of chemical , medicine and food industry.

——We own senior engineers who have rich experience in chemical engineering.

——Our products can be used in lab-scale, pilot-scale experiments and small-scale production.

——The experimental results are more authentic by using our products thanks to the continuous operation during the course of the experiments or pilot-scale experiments.

——We repaire imputed equipments out-of-warranty for UIC,POPE,BUCHI in the past few years, which made us accumulating rich experience.

We not only produce distillation equipment,

but also study distillation  process,improve the distillation equipment.

Services Dea provide

Technology Consulting
We provide technology consulting and plan designing, please contact with us if you are not satisfied the extraction separation effect with your products.

Feasibility studies and process development
As we all known, testing and process development of customers’ products plays an important role in the whole project. And an experimental result may always achieve better than the complex theoretical calculations. We have a process development team which has rich experience, we experiment new product and face new challenge everyday. Our Purpose: To conduct initial research and development process, to prove the feasibility of separation; to provide design data for industrial production systems; to select the appropriate equipment and optimize the design of the equipment by material properties for each experiment.

Provide experimental equipment
For the separation of mixtures, especially those who are not mature mixture used in the separation plant, a simple theoretical calculation is not enough. Testing and process development for product is crucial, experiment is always the fastest and most effective way to determine the feasibility of separate products, which is better than the results of complex theoretical calculations. Development and design processes are usually done in the secondary laboratory test equipment with a lot of experimentation. Thus, we have established an independent laboratory which is continuous improved.

Process Configuration Design
Maybe you only want to buy the main equipment instead of engineering procurement and construction out of financial condition. Meanwhile, maybe a complete and detailed engineering design plan will trouble you. And we can provide you the chemical plant engineering design for you on base of our long-period experience in engineering design and rigorous style of work,

After-sale service
Equipment supply, installment and moderating.
Operator training.

Our equipment has been assembled and tested prior to shipping finished, so it is a whole package, which can be used directly after unpacked. Please measure the size of the door in order to handle the equipment to the right position. For self-assembly, please inform in advance.
