Biodiesel distillation process
Improve biodiesel quality by enhancing cold flow characteristics and removing impurities through high-vacuum, high-temperature distillation, ensuring high purity levels.

Distills and Purifies Biodiesel Components
The high-vacuum distillation column from Crown Iron Works is engineered for biodiesel producers and offers superior separation of biodiesel components. It employs a high-vacuum, high-temperature distillation process to ensure minimal thermal degradation. This column excels in removing monoglycerides and low-volatility compounds, enhancing biodiesel purity and cold flow properties. It is suitable for producing various products like biodiesel, omega-3 capsules, and specialty chemical solvents. With a focus on energy efficiency, the equipment incorporates heat economization, reducing operating costs. Designed for continuous operation, it integrates seamlessly into existing production lines with a PLC-controlled system for ease of use. Available in corrosion-resistant materials, it includes an option for materials like stainless steel to suit chemical environments. Custom engineering support is offered to tailor the equipment to specific production needs.
