CO2 + sulfuric acid combined process for the decomposition of sodium phenolate in coal tar processing
Thread Content
Our facility currently uses the sulfuric acid decomposition process; due to the difficulties in wastewater treatment, we would like to switch to the sodium phenolate process. Since the source of CO2 is either coke oven gas flue gas or exhaust gas from tubular furnaces, the CO2 concentration in such gases is relatively low. I would like to ask if anyone in the same industry can tell me what the quality of crude phenol produced by companies that use coke oven gas flue gas or tubular furnace exhaust gas to extract CO2 is like For the CO2 + sulfuric acid method, what are the addition ratios of sulfuric acid and CO2, and what is the sulfate ion content in the wastewater?
Bro, I want to know which design firms are capable of designing phenoxide salt treatment processes at the moment?
Bro, which design institute designed the equipment for your company?
Many design institutes are capable of carrying out such designs; Baosteel and Pangang can also do it

The carbon dioxide and sulfuric acid method is used; after the decomposition of carbon dioxide, a small amount of sulfuric acid is required to adjust the pH value of the crude phenol. After the decomposition, the concentration of crude phenol is around 85%, the content of neutral oils is less than 0.8%, and the water content is about 10%.
Our company has a complete process for phenoxide salt decomposition and wastewater treatment. 13702159086, Wang.
