Can antibiotic by-product salts be used in chlor-alkali production?
Thread Content
Colleagues, I would like to ask if anyone is aware of whether the by-product salts from active pharmaceutical ingredient manufacturers can be used in chlor-alkali production. Our company has newly installed chlor-alkali production facilities; these facilities will help to handle hazardous waste while also providing a source for some of the liquid caustic soda needed as raw material. I beg earnestly
If antibiotics are produced by biochemical methods, the by-product salts may contain high levels of organic impurities and ammonium salts, which need to be strictly removed from the raw salt used in chlor-alkali production.
Are there any new chlor-alkali plants being built now?
What are the requirements of chlor-alkali enterprises for industrial salt? Ordinary sun-dried salt? Refined salt? Can industrial salt, a by-product of production, be used? How to deal with impurities?
I guess not. Some substances in the brine processing section cannot be removed; there seems to be a problem with the ion exchange resin
The waste salt is subjected to re-firing to remove impurities, moisture, and organic substances, thereby meeting the **first-class industrial salt standards. Then it is used in the chlor-alkali industry. My family helped modify this equipment; feel free to contact me if you need anything.
Yes, a pilot scale test of 5,000 tons was successful, and a plant has been built for processing. Our company processes 50,000 tons per year, specializing in the treatment of sodium chloride; after the treatment, it meets the standards for first-grade industrial salt before being sold.
The requirements for saltwater in chlor-alkali production are quite strict; it mainly depends on what impurities, including organic impurities, are present in the by-product salt. These impurities need to be removed through appropriate treatment before the salt can be reused. We have the necessary technologies to refine and purify this by-product salt so that it can be used again in chlor-alkali production.
How much was the investment for the previous 50,000 tons per year plant?
We specialize in evaporation crystallization, salt treatment, as well as custom equipment for titanium, nickel, and stainless steel. . . There are successful cases where salt meets the standards for use in chlor-alkali production, that is, it conforms to industrial salt standards
