en.Wedoany.com Reported - Sulzer Switzerland has recently launched an integrated dewaxing and deoiling system, a modern technology for wax and base oil production that optimizes separation efficiency by combining multiple processes. The system employs customized treatments for different wax types, including Solvent Dewaxing Units (SDU), solvent-based deoiling for microcrystalline wax, and static melt crystallization for large-crystal paraffin wax. It aims to address the increasingly stringent environmental standards and energy cost challenges in the refining industry.
The integrated dewaxing system is based on the principle of technological complementarity. The SDU serves as the core processing unit, using solvents such as Methyl Ethyl Ketone (MEK) and toluene to selectively crystallize wax at low temperatures, maximizing base oil recovery. Due to its complex crystal structure, microcrystalline wax undergoes solvent-based deoiling to remove residual oil content. In contrast, large-crystal paraffin wax utilizes solvent-free static melt crystallization, achieving efficient separation through freezing and heating processes, thereby reducing energy consumption.
This integrated model offers significant economic advantages. The static crystallization technology reduces capital expenditure, with investments being 30% to 50% lower compared to full-solvent configurations. Operational expenditures are also substantially decreased, with paraffin wax deoiling costs potentially reduced by up to 70%. Meanwhile, product yield increases from approximately 60% to over 90%, ensuring stable output of high-quality wax. The synergistic process design enables heat integration and material recycling, further optimizing overall performance.
The integrated dewaxing system represents an advancement in wax processing, combining solvent-based and solvent-free methods to provide operational flexibility and cost-effectiveness. Paraffin wax and microcrystalline wax, as strategic products, meet market demands and support sustainable production. Intelligent integration technology transforms wax production into a competitive advantage, driving industry innovation. For more details, please visit Sulzer's relevant web pages.
