本刊讯兰化研究院化学工程研究所开发的以渣油为原料大化肥炭黑回收技术，近日通过了中石化总公司组织的技术鉴定。该技术采用过滤吸附脱盐法，成功地去除了炭黑回收系统中的灰份和微量金属，缓解了气化炉结渣、灰水系统结垢等长期困扰工业生产装置，使其难以长周期稳定运行的 Journal of Lanhua Institute of Chemical Engineering developed by the Institute of residual oil as raw material fertilizer black recycling technology, recently passed the Sinopec headquarters technical appraisal. The technology uses the filter adsorption desalting method to successfully remove the ash and trace metals in the carbon black recovery system and alleviates the long-standing industrial production devices that have long plagued the gasification furnace slagging and the gray water system scaling and the like, making it difficult to long-term stability In progress
