  • in reply to: What is the price of bitumen emulsion? #322544

    The price of bitumen emulsion depends on grade, emulsifier type, and production capacity. GlobeCore equipment enables producers to maintain competitive pricing while ensuring product consistency.

    in reply to: How to test hydraulic oil for moisture? #322333

    The easiest method to test hydraulic oil for moisture is to use a portable tester like GlobeCore TOR-1, which delivers fast, on-site results without the need for laboratory analysis.

    The GlobeCore TOR-8 meets IEC 60567 and ASTM D3612 standards for dissolved gas extraction and analysis, ensuring compliance with international transformer diagnostic practices.

    Regular testing with GlobeCore TOR-7 identifies water, particles, and insulation degradation early, helping prevent transformer failures and outages.

    Due to its high FFA content, cod liver oil may require acid esterification (using H₂SO₄) before base-catalyzed transesterification with NaOH or KOH. A two-step method is most effective. For cleaner oil, base catalysis alone suffices. The GlobeCore USB plant supports both acid and base catalysis, with automated control of reaction stages, methanol ratios, and catalyst dosing, making it ideal for processing marine oils like cod liver. Enzymatic transesterification is also an option for small-scale, high-purity applications but is costlier.

    Sodium hydroxide (NaOH) and potassium hydroxide (KOH) are the most commonly used base catalysts for mustard oil biodiesel. The oil’s relatively low free fatty acid content usually allows for direct base-catalyzed transesterification without pre-treatment. The GlobeCore USB system is compatible with both catalysts and allows for fine-tuning dosage based on feedstock quality. Antioxidant additives can be used post-production to improve the stability of biodiesel made from high-erucic-acid oils like mustard.

    in reply to: How to convert palm oil to diesel? #317413

    Converting palm oil to diesel involves transesterification using alcohol and a catalyst. This creates fatty acid methyl esters—biodiesel—that can be used in diesel engines. For best results, the oil should be refined to reduce water and free fatty acids. The GlobeCore USB system ensures high-quality biodiesel output, with modules for heating, reaction, and separation built in. The process is fast, safe, and compliant with international biodiesel regulations.

    Producing biodiesel from rapeseed oil requires several key components: an oil press (to extract the oil), filtration units (to remove solids and impurities), a reactor for transesterification, and separation equipment for removing glycerin. Optional stages include methanol recovery and washing/drying of the final fuel. The GlobeCore USB biodiesel production plant integrates all essential stages except oil pressing, offering automated heating, mixing, reaction, and separation within one modular system. It is scalable, reliable, and engineered to deliver high yields with minimal labor, making it perfect for professional and industrial use.

    The USB 6 Impeller Stirrer features adjustable speed settings, automated process control, and real-time monitoring, ensuring accurate ingredient blending and formulation precision.

    Key equipment includes mixers like the USB 6 Impeller Stirrer, which provides efficient and homogeneous slurry preparation.

    in reply to: what is a power factor test? #315011

    A power factor test measures the phase difference between voltage and current in a dielectric material, indicating the level of energy loss and the quality of insulation.

    in reply to: what happens when a transformer leaks oil? #314955

    Cooling in transformers involves dissipating the heat generated during operation, often through natural convection or forced methods (using fans or pumps), with oil acting as the primary coolant.

    in reply to: is specification of transformer oil? #314797

    Transformer oil specifications include parameters such as dielectric strength, flash point, viscosity, acidity, moisture content, and pour point, ensuring the oil performs safely and effectively.

    Nitrogen is introduced into transformers during transportation to displace oxygen and moisture, thereby preventing oxidation and degradation of the oil and internal components, which helps maintain the transformer’s performance and prolong its service life.

    in reply to: how often should transformer oil be changed #314642

    Transformer oil is usually replaced according to manufacturer guidelines and condition-based monitoring; routine changes might be scheduled every five to ten years, but if oil testing reveals significant degradation, contamination, or moisture ingress, an earlier change is recommended.
