The biodiesel production plant is a fully integrated system designed for efficient transesterification, purification, and byproduct recovery to produce high-quality biodiesel. Ocean specializes in designing, manufacturing, and supplying biodiesel production plants. We offer everything from project planning and custom designs to guidance of installation and after-sales services, ensuring your plant operates smoothly.
1.Pre-treatment
A biodiesel production plant begins with feedstock pretreatment. Raw oils are filtered to remove impurities, then heated and settled to eliminate moisture. The process converts free fatty acids into neutral oils, ensuring cleaner input for efficient production.
2.Esterification
Ocean’s biodiesel production plant mixes raw oil, methanol, and a catalyst in precise ratios. Under normal pressure and 95–110°C, free fatty acids react with methanol to form methyl esters—an essential step that improves feedstock quality and stability. Recovered methanol is reused through advanced neutralization and distillation systems, ensuring efficient and sustainable biodiesel production.
3.Transesterification
Biodiesel production continues with the transesterification stage. The pre-esterified materials are neutralized and dehydrated, then mixed with methanol and a catalyst in precise ratios. The reaction takes place in a tubular reactor under controlled temperature. After methanol removal, the mixture settles again for glycerin separation.
4.Glycerin Treatment
The biodiesel production line includes a dedicated glycerin treatment section designed for efficient byproduct recovery. Crude glycerin is first heated to remove residual methanol, then acid-neutralized and settled to recover fatty acids for reuse in methyl ester production. After pH adjustment, the refined glycerin is ready for sale, enhancing overall resource utilization and process sustainability.
5.Biodiesel Distillation
Biodiesel production achieves final purification through multi-tower vacuum distillation. Crude methyl ester is refined to remove sulfur compounds and impurities, producing high-purity biodiesel. The biodiesel production plant uses thermal oil heating and energy recovery design, ensuring an efficient and stable distillation process.
6.Methanol Recovery
Excess methanol and exhaust gases from esterification and transesterification are first neutralized, then sent to the methanol distillation system for recovery. This recycled methanol reduces emissions and improves overall process efficiency.
The biodiesel production plant from Ocean delivers high conversion efficiency, superior product quality, and low energy consumption. It minimizes environmental impact, eliminates waste acid water discharge, and addresses common issues such as high sulfur content and excessive glycerin in the final product.
Customer-Centric Solutions
Tailored designs to meet your unique operational and business needs, ensuring your turnkey biodiesel project runs efficiently from planning to full-scale operation.
High Yield Efficiency
Engineered to yield 10-1000 tons per day, helping your biodiesel production system achieve exceptional output with lower operating costs.
Eco-Friendly Production
Ocean integrates advanced purification and recovery technology to ensure minimal emissions and waste generation, supporting a cleaner and sustainable production environment.
End-to-End Service
From installation to technical training and after-sales services, Ocean provides end-to-end support to keep your biodiesel plant performing at its best.
The biodiesel production line is designed to handle a wide range of raw materials, including but not limited to vegetable oils, animal fats, used cooking oil (UCO), fatty acids, and acid oils. This flexibility allows the plant to effectively convert both oily and acidic feedstocks through esterification and transesterification processes, ensuring high resource efficiency and stable production performance.
The decanter centrifuge performs efficient solid–liquid separation, removing water and impurities from feedstock oils. It ensures cleaner input and enhances transesterification efficiency, resulting in higher biodiesel yield and product quality.
The integration of a methanol distillation tower enhances the biodiesel production plant’s efficiency by continuously recovering and refining unreacted methanol. This closed-loop system lowers raw material consumption, reduces emissions, and ensures a cost-effective, environmentally friendly operation.
As the core unit of the biodiesel production plant, the transesterification reactor enables fast and complete conversion of oils or fats into biodiesel through efficient mixing and precise temperature control. It ensures high reaction efficiency, stable product quality, and reduced energy consumption.
