摘要


影響輕油裂解工場(乙烯工場)乙烯產率的主要因素有裂解爐型式與構造、操作條件(如裂解溫度、滯留時間、油料分壓、有無添加積碳抑制劑等)、以及原料特性。本報告以台灣中油公司四輕裂解工場為研究對象,以其現有進料為基礎,著重於裂解爐型式差異性、裂解爐更新、及更新後之經濟效益評估。四輕裂解工場於於94~96年期間爐管由SRT-Ⅲ型更新為SRT-Ⅵ型,若以內部轉撥計價和最終產品計價為基礎,SRT-Ⅵ型新爐管之年平均效益約為新台幣3億元。另外,在相同之進料品質下,SRT-Ⅵ型爐之熱效率較SRT-Ⅲ型爐高約2%。

The purpose of this project is to revamp the cracking furnaces of the No.4 Naphtha Cracker in CPC. The original SRT-Ⅲ type furnace Coil was replaced by SRT-Ⅵ type furnace Coil, and convection area was also modified to new configuration in order to upgrade production yield and heat efficiency.With an annual profit of NT$300 millions was estimated to gain in this project after a restart-up test. The heat efficiency of the furnace was also improved by 2%.
