Jiujiang Petrochemical combines the characteristics of the season, taking multiple measures, and pays close attention to the quality control of the whole process of styrene products. From June to September, the company has shipped a total of 17 ships of styrene, all of which have achieved superior quality, effectively ensuring the company's economic benefits.
Styrene is an important organic raw material for the production of plastics and synthetic rubber. The market demand is strong and the economic benefits are considerable. However, as a chemical raw material, the physical properties of styrene are delicate, and when the temperature is high, it is easy to produce a polymerization from styrene to polystyrene. reaction.
Since June, Jiujiang Petrochemical has been concerned with the quality control problems of styrene in the high temperature season. Through perfecting the system, the quality is strictly controlled from the source, the polymer monitoring of the finished tank and dock return line is strengthened, and various measures such as storage and delivery cycle are arranged reasonably. 3. Ensure that the quality of styrene products meets the standards.
They focus on the chemical production characteristics of styrene plants, strictly control the process parameters, fine-tuning and fine-tuning, and keep the device running smoothly. At the same time, the styrene quality management rules are established, and the equipment distillation outlet, semi-finished products (intermediate tank), finished products, and factory are specified. The quality responsibility of each part of the mixed sample is implemented. They strictly analyze the analysis, implement special posts, strengthen the quality analysis data feedback and early warning, and ensure that the styrene products always maintain excellent quality.
In order to prevent fluctuations in product quality caused by high temperature in summer, they strengthened the monitoring and management of polymer storage tanks and dock return line polymers while strengthening process operation management and operation and maintenance of refrigeration equipment, and adjusted the original weekly quality analysis and monitoring to In addition, they also shortened the shipping time of the factory from the previous ten days to six days according to the production and quality of styrene. By reducing the storage and transportation cycle, the styrene is accelerated, which effectively avoids the quality risk in the hot season.
