一种从柴油中脱出环烷酸的工艺方法
摘要：
本发明涉及石油产品中酸性物质脱除技术，提出一种从柴油中脱除环烷酸的工艺方法。在高效微波反应罐中加入馏分油和脱酸剂，无需预混合，直接移入高效微波反应系统中进行微波辐射。经过沉降分离，脱酸剂携带环烷酸形成的酸相与油相完全分离，脱酸率达98％以上，油品回收率达99.0％以上；酸相与同体积30％的硫酸混合，沉降分离，分为上下两层，上层为环烷酸，下层为硫酸盐溶液。在该工艺过程中，没有出现乳化现象，提高了油品的质量和产率，节约生产成本，具有高效、节能、利于环保等特点。
摘要（英）：

The present invention relates to acid matter eliminating technology for petroleum product, and is technological process of eliminating naphthenic acid from diesel oil. After fraction oil and deacidifying agent are added directly into microwave reactor, the microwave reactor is transferred into efficient microwave reaction system for microwave radiation. After deposition separating, the deacidifying agent with carried naphthenic acid is separated completely from the oil phase in deacidifying rate over 98 % and oil product recovering rate over 99.0 %. The separated acid phase is mixed with 30 % concentration sulfuric acid in the same volume for depositing separation into the upper layer of naphthenic acid and lower layer of sulfate solution. The said process has raised oil product quality and output, no emulsification, low production cost and environment friendship.
