Treatment methods for terephthaloyl chloride products

For terephthaloyl chloride products, there are usually several methods for processing the qualified liquid product after distillation. If you choose to cool the product directly, slice it, and then package it, this is feasible and can ensure the product’s quality and stability. Another feasible option is to store the liquid product in the storage tank area for about 7 days, and then pump it to the slicing workshop for slicing and packaging. The key to this method is to ensure the quality and safety management of phthaloyl chloride during storage, such as preventing contamination by impurities and controlling the storage temperature, in order to avoid any factors that could lead to a decline in quality. During the transfer process, attention must also be paid to the materials and maintenance of the pipes and pumps, to ensure that they do not react with phthaloyl chloride or affect its purity. In short, both methods are feasible; the key is to choose the most suitable treatment method based on your production conditions and quality control standards. .

What is the outlet temperature of the distillation tower for terephthaloyl chloride? If the temperature is suitable, rather than using direct air cooling or water cooling, it is better to install an ORC waste heat generator, which saves on cooling water needs and also generates electricity for revenue.

The temperature is around 95°C. The main issue at present is whether storage under atmospheric pressure using a fixed-roof tank is feasible I wonder if Haiyou is aware of this?
