独山子煉油厂的焦化車間是以苏联供給的設計和設备所兴建的釜式焦化裝置,从兩年来的实际生产情况来看,我們認为原料油的性質对釜式焦化过程有很大的影响。对于不同性質的原料油选擇正确的操作条件(如装料量,升温速度,烘焦时間等)是保証焦化裝置能够平稳生产的关鍵。因此,我們对于处理各种原料油的操作方法进行了較長时間的摸索,在操作技术上和設备上陆續作了一些改进。这样,对提高产率、降低損失、縮短週期、減輕工人劳动强度和节約材料等方面都起了一定作用。現將部分經驗和改进叙述于下:
Coking plant in Dushanzi refinery is a kettle-type coking plant built with the design and equipment supplied by the Soviet Union. According to the actual production situation in two years, we think the nature of the feedstock has great influence on the kettle coking process influences. Choosing the right operating conditions (such as loading capacity, heating rate, baking time, etc.) for different types of feedstocks is the key to ensure smooth production of the coking unit. Therefore, we conducted a long period of exploration on the operation methods for handling various kinds of feedstock oils, and made some improvements in operation technology and equipment. In this way, it has played a certain role in improving productivity, reducing losses, shortening the cycle, alleviating the labor intensity of workers and saving materials. Now part of the experience and improvement narrated in the next:
