The pH value is key
Quality assurance in biodiesel production
Biodiesel is a renewable and environmentally friendly alternative to conventional diesel fuel. Final neutralization and washing are crucial steps in the manufacturing process to ensure the quality of the end product. An optimum pH value ensures purity and stability and prevents corrosion during subsequent use.
Customer benefits
Extended sensor lifetime
Reduced maintenance costs
Improved biodiesel quality
Efficient production process
The challenge
During biodiesel washing, impurities such as methanol and alkalis are removed. Acids neutralize the product, but monitoring the pH value is challenging due to low conductivity and high temperatures. Nevertheless, precise pH control is essential to ensure the purity and stability of the final product.
Our solution
The digital pH sensor Memosens CPS11E ensures reliable measurements in low-conductivity media using a special salt storage that stabilizes reference values. Its B-glass design withstands high temperatures, while an ion trap protects against harmful ions in biodiesel production. This extends sensor life, reduces maintenance, and ensures accurate pH control for efficient production and high biodiesel quality.
