我国的第一台催化裂化可调热量下流式外取热器在牡丹江炼油厂于1983年9月18日投用后,经过一年多的正常稳定生产在1984年7月12日至14日进行了标定,取得23套数据,生产正常,操作平稳,产品合格,达到了预期目的.最大取热负荷超过了原设计负荷(200万千卡/时),达222.6万千卡/时,传热系数平均为418～456.5千卡/米~2·时·℃.长期稳定生产和标定结果证明,催化裂化可调热量下流式外取热器的工艺、设备结构设计是合理、可靠的.生产中不仅增加了渣油的掺炼量,提高了轻质油收率,而且使再生
China’s first catalytic cracking adjustable heat downstream condenser in the Mudanjiang refinery on September 18, 1983 put into use, after more than a year of normal and stable production in July 12, 1984 to 14 days The calibration, obtained 23 sets of data, the production is normal, the operation is steady, the product qualified, has achieved the anticipated goal.The biggest heat load surpasses the original design load (200 million kcal / hour), achieves 2,226,000 kcal / hour, the heat transfer The average coefficient of 418 ~ 456.5 kcal / m ~ 2 · when · ℃. Long-term stable production and calibration results show that the process of FCCU adjustable heat extraction process, equipment structure design is reasonable and reliable. Not only increased the amount of residue blending, increased light oil yield, but also to renewable
