May I ask whether a company with Class B environmental protection qualifications is qualified to issue documents and drawings for the distillation of methanol from methanol and water? Are there any qualifications required for the signatories as well?
It’s probably beyond the scope. If the project investment is below 300 million, qualifications such as Class B for chemical engineering or Class B or higher for the petrochemical, chemical, and pharmaceutical industries are sufficient to produce the necessary drawings.
Which part is going over the limit? Is a pressure vessel and pressure pipeline certificate required for distillation?
1. Methanol distillation is a typical chemical process, and environmental compliance requirements only permit the design for waste (water, gas, solids) treatment and soil remediation. 2. For methanol distillation, if a chemical engineering design qualification is adopted, such qualification includes a \"pressure vessel and pressure pipeline certificate\".
Then, can a design document be prepared for wastewater treatment that involves hazardous materials such as methanol, under an environmental protection classification of Grade B?
As long as it is part of the design within the BL line of the “wastewater treatment unit,” the environmental design qualifications are sufficient to cover it.
But when it comes to hazardous materials, according to Document No. 76, it seems that a special qualification for the chemical industry is required
The hazardous materials involved in the wastewater treatment unit are generally chemicals; since the unit does not produce hazardous materials, it can have environmental protection certifications. But I believe that a complete project will not choose a different design firm (with different design qualifications) just because of the design characteristics of a certain component, right?
