The hygroscopicity of biodiesel (B40) is a challenge in the processing of natural resources. This hygroscopicity significantly impacts quality degradation and combustion efficiency. Hygroscopicity is the property of a material to absorb or attract water vapor (humidity) from the surrounding air. Biodiesel contains ester groups (–COO–) that tend to form hydrogen bonds with water. These group…

Transformer oil serves as a liquid insulation that maintains the stability of the insulation system and prevents dielectric breakdown in transformers. Over time, transformer oil deteriorates due to increased moisture content, acidity levels, changes in density, and a reduction in breakdown voltage, which may compromise the dielectric strength of the oil. This study aims to restore the quality o…
Oil is one of the most important energy sources for human life. One of the common causes of the decline in oil production is the decrease in pressure in reservoirs, because the primary energy used to lift oil to the surface will be reduced over time. TheHall Plot method is most often used to analyze the performance of an injection well bymaking a curve, between pressures multiplied by a certain…

Transformer oil is a liquid insulation that is used as a lubricant in transformers, and as a heat transfer or safety guard for the temperature inside the transformer. When transformer oil is used continuously, its quality as liquid insulation will decrease, which is caused by several factors, including oxidation that occurs in the tank. Contaminants from outside and so on. If this happens, the …
Transformer oil is one of the liquid insulating materials, with the main components of transformer oil involving hydrocarbon elements or compounds, including paraffinic, naphthenic, and aromatic hydrocarbons. Contaminants in transformer oil can cause impurities. The addition of phenol and Butylated Hydroxytoluene (BHT) can reduce the contaminant content. Research was conducted to determine the …
