300,000 tons of acidic water stripping
Thread Content
The 300,000-ton per hour acidic water stripping process does not use his type of catalyst; it features an ammonia extraction line. The sulfur compound level is around 300, while the ammonia nitrogen level is 80. How can these levels be reduced? The top temperature should be controlled at 80 degrees, and the ammonia extraction temperature should be around 150 degrees. The amount of acidic water used is very small, only 3 tons per hour. The main problem is that the top temperature cannot be controlled. After cooling, the temperature still doesn’t drop, remaining quite high. How can the sulfur compound level be reduced?
The format of this text is messy, it contains spelling errors, and some parts need to be selected and corrected: “300,000 tons per year of acidic water stripping – packing is used instead of trays; there is an off-stream line for ammonia extraction. The amount of acidic water is very small, 3 tons per hour.” ——I have a question – perhaps it’s due to my limited knowledge, but I really haven’t seen it before: where does the amount of acid water come from in such a manufacturing process?
The specific process is not clear; the top temperature cannot be controlled. It is possible to reduce the amount of product taken from the top of the tower, increase the reflux at the top, and keep the ammonia extraction temperature low – temperatures above 135 degrees are no problem
