摘　　要：采用碳化-氧化法处理炼油厂碱渣,先用碳化法将炼油厂碱渣分离成有机相和无机相,再采用氧化法去除无机相中的恶臭物质(主要为残余硫化氧和硫醇等);在该方法中增加了轻质碳酸钙生产工艺,可用苛化渣生产轻质碳酸钙产品。实验结果表明,采用碳化-氧化法处理炼油厂碱渣,既能得到 NaOH 质量分数为10%～12%的碱液回用,又能得到粗酚、硫磺和轻质碳酸钙产品(干基质量分数为97%,出售)。碳化-氧化法处理碱渣制备轻质碳酸钙可实现资源综合利用,节约苛化渣外运填埋的相关费用和用地,年净增经济效益约100万元。The carbonization-oxidation process was used to treat refinery alkaline residue. First, the residue was separated into organic phase and inorganic phase by carbonization. Then, the malodorous matters such as sulfurated hydrogen and mercaptan were removed from inorganic phase by oxidation. The process is combined with the technology of producing light nature calcium carbonate from the residue. The process can produce NaOH solution of 10% - 12% mass concentration for reuse, crude phenol, sulfur and light calcium carbonate （ dry base mass fraction 〉 97% ） for selling. It is showed that the process can realize the comprehensive utilization of the residue, saving its treatment and dispose costs, and has significant economic benefit.
