摘要
锦州石油化工公司５００ｔ／ａ环丁砜装置经过改造，提高了产品的耐热性和ｐＨ值，并降低了产品中对苯二酚的含量。改质后的环丁砜用于锦州石油化工公司３００ｋｔ／ａ催化重整的芳烃抽提，表现出优良的选择性和稳定性。
After the revamping of the sulfolane unit with 500t/a capacity in Jinzhou Petrochemical Company, the product quality was improved, such as the heat resistance and pH value Increased and the hydroquinone content reduced. The upgrading sulfolane shows superior selectivity and stability in the application of aromatics extraction of the 300kt/a reforming unit.
