Can the produced and purified butanol be sold as a by-product?
Thread Content
Butanol with a purity of 99.0% is used as a solvent in the production process by the manufacturing facility; at the end of production, the butanol is removed under vacuum, resulting in a purity of around 95%, along with moisture content
It’s such a good thing; how could it be considered waste?
The last edit to this post was made by WQH518 on 2021-12-29 at 10:14. First, it is necessary to check whether the business scope listed on the company’s business license includes the sale of butanol products； Second, it is necessary to check whether the recovered butanol product meets the corresponding ** or industry standards. If these two conditions are not met simultaneously, selling butanol by-products constitutes operating outside the permitted scope (which is also considered illegal business operations) or the illegal transfer of waste.
We can consider whether to use equipment to recycle this butanol
Thank you for your explanation. I was considering these two aspects as well; since butanol is our raw material, its sale is certainly not part of our business scope. The purity of the recovered butanol is 95%, which definitely does not meet the national standards (>99%). I just want to see if there are any other possibilities.
Equipment such as distillation towers can be used for purification, but this is not possible at the moment due to a range of issues related to project approval and other matters; therefore, it is part of the plans for several years ahead.
