Idiay makabukel a bulan ti Marso, ti styrene a pabrika ti Baling Petrochemical Refining Department ket inorganisar manen ti tuloy-tuloy a panagpasayaat ti analisis ti value stream map, a nag-combinar ti bottlenecks iti operasyon ken panaggastona ti enerhiya ti aparato, ken nakisarita iti optimization ken panagpasayaat a dagus. Daytoy ti normal a kasasaad a kasapulan ti aparato a mangipangpangruna iti problema, a masolbar ti problema babaen ti problem-solving platform, ken umuyong ti potensial.
Solve problems online and promote long-term operation of the device. The styrene plant has an annual production capacity of 120,000 tons, which is mainly used to supply raw materials for downstream chemical plants. The ethylbenzene evaporation heat exchanger of the device has experienced internal leakage, which causes ethylbenzene to leak into the steam condensate. If it is stopped, it will directly affect the output of nearly 7,500 tons in 20 days, and increase the consumption of open and stop materials and energy consumption. Ten thousand yuan. In this regard, the styrene plant combines the characteristics of the process, proposes the transformation method and is recognized by the design unit. The steam condensate is used as the system water, and the ethylbenzene vapor separation tank is introduced, which solves the problem quickly and Ipasiguradona ti agtultuloy a panagandar ti alikamen..
Implement "minimally invasive surgery" to stabilize product quality. Li Qin, director of the device, said that in the middle of last year, the polymer content of styrene products was continuously high, fluctuating within the range of 6-9 mg/kg. Although it can meet the national standard requirements, it is less than 3 mg/kg expected by users. There are still gaps in the goals. Therefore, the Ti alikamen ket dagus a nangorganisar ti panagsukisok, ken nagtagtaginayon kadagiti lima a "seksion ti panag-brainstorming" tapno mangpormula kadagiti plano ti panagtignay para kadagiti innem a nangruna a proyekto ken 35 a babassit a proyekto, ken nangipatungpal ti nasayaat a "minimally invasive surgery" iti Styrene Separation Tower tapno mapatalged ti linaon ti polimero. iti baba ti 3 mg / kg, daytoy ket maawat babaen dagiti kustomer{9}} .

Li Qin said that since 2015, the styrene plant has routinely discovered and solved the problem of the device, insisted on "general problems, and complicated problems, and worked hard to solve problems", and continued to promote energy conservation, consumption reduction and production increase. Economic and technical indicators such as output, production, material consumption and energy consumption continue to record, producing more than 480,000 tons of styrene, which has remained profitable for Tawen. .
