What are the criteria for determining whether the products of atmospheric and vacuum distillation are qualified? Could you explain it in more detail, or recommend some books or materials?
Every company has its own corporate standards, and there are even more of these when it comes to by-products.
1. Some enterprises have their own standards for products, and they use these standards to determine whether their products meet the required criteria. . . 2. If there are no product testing and inspection standards established by the company itself, then industry standards such as those from the petroleum or petrochemical sectors should be referred to. For example, straight-run gasoline can be tested using the standards for naphtha, while diesel can be produced in accordance with the current national standards for finished diesel, or it can be made to meet those standards. . . 3. For paraffin oil, only residual carbon, density, and moisture are evaluated. . . Residual oil is produced in accordance with the fuel oil specifications or the supply targets agreed upon with the customer. . . :lol
