糠醛是一种有机溶剂,在我国石油工业润滑油糠醛精制中,应用已有三十多年的历史。自一九五四年。石油七厂第一套年仅2万吨加工能力的润滑油糠醛精制装置投产以来,随着石油工业的飞速发展,糠醛装置不断增多。虽然近几年萃取溶剂在不断更新,但现全国仍有大小润滑油糠醛精制装置十六套,加工能力达262万吨/年,糠醛耗量约达2100吨/年(单耗按0.8公斤/吨计算)。随着润滑油糠醛精制能力的不断提高,在生产中暴露出的主要矛盾是糠醛对普通碳
Furfural is an organic solvent, which has been used for more than thirty years in China’s oil industry, furfural oil refining. Since 1954. Since the commissioning of the first set of lubricating oil furfural refining equipment with an annual processing capacity of 20,000 tons, the first seven sets of oil seven plants have been increasing with the rapid development of petroleum industry. Although the extraction solvent is continuously updated in recent years, there are still 16 sets of furfural refining devices with the size of 2.62 million tons / year and the furfural consumption of about 2100 tons / year (the unit consumption is 0.8 kg / Ton calculation). With the improvement of lubricating oil furfural refining capacity, the main contradiction exposed in the production of furfural on ordinary carbon
