3 Terms and definitions
The following terms and definitions defined in GB/T 18820 and GB/T 21534 apply to this document.
3.1
Paraxylene production
Using the reforming reaction product as the raw material, it undergoes aromatic extraction, toluene disproportionation and transalkylation, benzene toluene separation, isomerization, xylene rectification, and absorption.
The whole process of p-xylene production with processes such as attachment/crystallization separation.
3.2
Water withdrawal per ton of p-xylene
During the statistical period, the entire process of producing each ton of p-xylene requires the amount of water extracted from various conventional water sources.
4 Calculation method
4.1 General rules
4.1.1 Scope of water withdrawal
The scope of water withdrawal refers to the amount of water extracted by the company from various conventional water sources, including surface water (measured by water purification plant water supply), groundwater,
