Jilin Yida Chemical Co., Ltd. 2-Ethylanthraquinone Plant Renovation Project
Thread Content
Jilin Yida Chemical Co., Ltd.’s 2-ethylanthraquinone plant renovation project: This project is located in the Economic and Technological Development Zone of Jilin Province, and it is funded and constructed by Jilin Yida Chemical Co., Ltd. Technical upgrades were carried out on the anthraquinone unit and the by-product ammonium sulfide unit; as a result, the production capacity of 2-ethylanthraquinone (2-tert-amylanthraquinone) remained unchanged, while an additional 15,000 t/a of dilute sulfuric acid was produced ； Adjustments have been made to the types of raw materials stored in the product and raw material storage areas, the sulfuric acid storage area, and the liquid ammonia storage area, as well as to the quantities stored and the number of loading/unloading platforms. The total investment for the project is currently unknown.
