Rough phenol refining
Thread Content
In coal tar processing units, the yield of crude phenol is very low; therefore, the purification of crude phenol obtained from coking is generally carried out using batch distillation. Currently, there are some plants where the output of crude phenol is high, and if a continuous process is used for its purification, are there any other methods aside from the Baosteel process?
It depends on the design intent – are there any new process or product requirements?
The treatment of crude phenol aqueous solutions turns waste into treasure. It is expected to be promoted. Solve environmental issues to promote corporate development.
For the continuous distillation of crude phenol, the key factor is the required purity of the product, with investment cost being a secondary consideration
Yes. Many design institutes have developed a continuous distillation process for crude phenol, which has been put into production.
What is the reason for the product to change color and turn brownish-yellow?
Purity is one aspect; color is also very important.
Oxidation requires nitrogen sealing; avoid exposing the finished product in barrels to direct sunlight
Are there any customers who sell crude phenol? I’m interested. There’s also sodium phenolate – please get in touch with me if you’re interested. No unsolicited inquiries
Thank you. What I’m doing now is storing them in 200KG barrels in the workshop; sunlight shouldn’t get in there, right?
On January 28, the world’s first industrial demonstration plant for the clean production of phenol, built by Shanxi Coal Chemical Shenmu Tianyuan Co., Ltd. using its own proprietary complex extraction technology, has been in operation for 3 months now. To date, it has produced over 600 tons of phenol, o-cresol, m-cresol, and xylene products with a purity of 99.5% or higher. This marks our country’s successful resolution of the global challenge related to the clean production of phenol, with the industrialization technology for such clean production reaching world-leading levels.
