環保脫芳溶劑的開發成果

傳統芳香烴溶劑具有高度溶解力，廣泛應用於工業及民生用途，然而這類含有苯環分子結構的物質屬於高度揮發性的有機脂溶性溶劑，已證實為人體致癌物。中油公司溶劑化學品事業部長期以來扮演穩定供應國內各種大宗溶劑的角色，由於傳統芳香烴溶劑產品有上述諸多問題，基於環保趨勢與中油公司面臨轉型之際，因而投入環境友善產品-環保脫芳烴溶劑的開發。本研究主要透過加氫催化製程，將自有原料中的苯環分子予以飽和大幅降低毒性，轉變為環保脫芳溶劑。由於加氫反應常伴隨大量放熱，除以試驗工廠尺度反應器進行評估測試之外，並透過製程模擬放大了解製程可行性，最後於工場進行試產與正式投產。目前D80環保脫芳溶劑已正式對外販售，其產品規格符合與國際大廠一致，經實際驗證後產品性能可符合市場需求，此產品特點為環保、低毒、無味，並榮獲2022年第19屆國家品牌玉山獎（最佳產品類）。

Traditional aromatic hydrocarbon solvents have high solubility and are widely used in industry and people's livelihood, however, such substances containing benzene ring molecular structure are highly volatile organic fat-soluble solvents and have been proven to be human carcinogens. CPC Solvent & Chemicals Business Division has long played the role of stable supplier of various domestic commodity solvent. Due to the above-mentioned problems in traditional aromatic hydrocarbon solvent products while CPC is facing business transformation, it has dedicated to develop environmentally friendly products such as de-aromatic solvents. This research aims to utilize the catalytic hydrogenation process for CPC self-owned raw material to greatly reduce the toxicity and transform it into an environmentally friendly de-aromatic solvent. Since catalytic hydrogenation reaction generates massive reaction heat, in addition to the evaluation test in pilot plant, the feasibility of process scale up is confirmed through process simulation, and finally the trial production and formal production are carried out in the factory. At present, the D80 de-aromatic solvent has been officially roll out in 2022, its product specifications are consistent with those of international manufacturers. After actual verification, the product performance can meet market requirement. This product is characterized by environmental protection, low toxicity, and odorless, and won 19th National Brand Yushan Award (Best Product Category 2022).
