In the petroleum processing industry, ketone-benzene dewaxing and deoiling technology, as a key process, plays a crucial role in enhancing production efficiency. This article will deeply explore the key steps of ketone-benzene dewaxing and deoiling technology and reveal its importance and advantages in petroleum processing.
1. Selection of ketone-benzene
Ketone-benzene is a commonly used solvent with good solubility and selectivity, which can effectively dissolve the wax and impurities in crude oil. Choosing the appropriate ketone-benzene is crucial for the dewaxing and deoiling process, which can affect the quality and purity of the final product.
2. Mixing and stirring
Mix the selected ketone-benzene with the crude oil and conduct sufficient stirring to ensure sufficient contact and mixing between the ketone-benzene and the crude oil. This step can promote the dissolution of wax and other impurities, laying a good foundation for the subsequent dewaxing and deoiling.
3. Cooling process
Cool the mixture to a certain temperature, usually below room temperature, to make the wax and other impurities solidify and precipitate. Controlling the temperature and time of the cooling process is the key to ensuring the effective precipitation of wax, which can be adjusted according to the characteristics and requirements of the crude oil.
4. Separation and filtration
Separate the cooled mixture to separate the precipitated wax and impurities from the ketone-benzene. Separation and filtration are achieved through methods such as centrifugation or filtration to ensure the purity and quality of the final product.
5. Ketone-benzene recovery
The separated ketone-benzene can be recycled and reused through methods such as distillation to reduce costs and resource waste. An effective ketone-benzene recovery system can improve production efficiency and economic benefits.
6. Summary
Ketone-benzene dewaxing and deoiling technology is one of the key steps to enhance the efficiency of petroleum processing. Its excellent solubility and selectivity can effectively remove the wax and impurities in crude oil and improve the quality and purity of the product. By controlling the key steps and optimizing the process flow to achieve the efficient operation of ketone-benzene dewaxing and deoiling will bring considerable economic benefits and competitive advantages to petroleum processing enterprises.
