Explanation of professional terms and practical application cases
Purified terephthalic acid (PTA): It is an important chemical fiber raw material and is widely used in polyester fiber production.
Take a new PTA project as an example. Its process flow includes key steps such as oxidation of paraxylene and separation of crude terephthalic acid. Energy consumption can be significantly reduced by optimizing the energy efficiency of process air compressors and dehydration tower reboilers.
Background of Standard Formulation and Analysis of Technological Evolution
With the rapid development of my country's chemical fiber industry, the energy-saving demand of purified terephthalic acid projects has become increasingly prominent. This standard is based on basic standards such as GB/T 31341 and GB 31533, and combines advanced processes and technologies at home and abroad to further refine the specific requirements for energy-saving assessment.
Implementation Suggestions
- Preliminary preparation stage: Ensure full communication with the construction unit and clarify the boundaries and scope of project energy use.
- On-site investigation stage: Pay attention to the utilization conditions of surrounding surplus energy and optimize energy allocation plans.
- Energy-saving measures evaluation stage: Compare advanced processes and equipment at home and abroad, and put forward operational improvement suggestions.
