【JST-201】One-on-one discussion thread: TianDa distillation technology and process packages
Thread Content
In chemical engineering projects, the three transfers and one reaction play a key role; among them, reaction and mass transfer are the most challenging aspects of such projects. 1. There are numerous domestic manufacturers specializing in distillation technology, yet only a few excel in this field. Processing equipment and factory conditions are not the key factors that determine success. The key to the problem lies in technology! For example, in a constant-pressure column with 30 trays, if each tray experiences an efficiency loss of 1%, the overall design efficiency for all 30 trays will be equal to 99 raised to the power of 30, which results in an efficiency of 74%. A decline in efficiency leads to a drop in product quality, increased energy consumption, and production costs that remain higher than those of competitors, with no identifiable reason for this. 2. The soul and core of a packed tower lies in the distributor; the quality of the distributor directly determines the separation efficiency of the tower. 3. There are many books on distillation technology available online; we need to learn to combine theory with practical engineering applications. Welcome everyone to discuss and exchange ideas!
Continuous distillation process for phenylphosphorus chloride series products I. Batch process The traditional batch process for phenylphosphorus chloride series products is characterized by high energy consumption, low product purity, and poor level of automation. II. Introduction to the continuous process 1. Under the action of a catalyst, chlorobenzene and phosphorus react in a high-temperature, high-pressure reactor to produce mixtures such as phenyldichlorophosphine, diphenylphosphine chloride, triphenylphosphine, and phosphorus trichloride. The product components account for about 95% of the reaction material components. 2. The mixture produced by the reaction is transferred to the light-end removal tower; the mixture of chlorobenzene and phosphorus trichloride obtained from the top of the tower is fed back into the reaction system ； The material from the bottom of the tower enters Tower 1 for product distillation. 3. The 1# product distillation tower operates under negative pressure; phenyl dichlorophosphine is extracted from the top of the tower, with a product purity of >99%. The material from the bottom of the tower enters the 2# product distillation tower. 4. The distillation column for Product 2# operates under negative pressure; diphenylphosphine chloride is obtained from the top of the column, triphenylphosphine is obtained from the side stream, and the material at the bottom of the column consists of high-boiling substances. The purity of all products is >99%, meeting the quality requirements. (Set of distillation reactor internals)
When it comes to distillation technology, Tianda is indeed the strongest:victory:
I hope the original poster will participate more in the discussions and answer the questions of other users; in that way, the business will surely grow bigger and better!
It would be amazing if this reaction process could be widely adopted
