In recent months, as the conflict in the Middle East—involving Iran—has escalated, the global oil market has experienced significant turbulence, sparking concerns regarding potential supply disruptions in one of the world’s most critical energy regions. According to global gasoline price data, fuel costs have surged substantially in numerous countries: gasoline prices in the Philippines have risen by over 50%, while Nigeria has seen an increase of nearly 49%; concurrently, gasoline prices in the United States and Canada have climbed by approximately 25% to 30%.
Driven by a continuously growing global population, the daily demand for primary energy sources is constantly on the rise. Gasoline stands as one of the most widely utilized fuel sources in use today, serving primarily as the fuel for spark-ignition internal combustion engines. It consists predominantly of organic compounds derived through the process of petroleum distillation. Various additives are incorporated into gasoline to enhance its performance characteristics, and it is frequently blended with ethanol to mitigate the environmental pollution resulting from its combustion.
In response to the prevailing international landscape—and in strict adherence to the ASTM D4815 Standard Test Method for Determination of MTBE, ETBE, TAME, DIPE, tertiary-Amyl Alcohol and C₁ to C₄ Alcohols in Gasoline by Gas Chromatography—our company has introduced the HKL-4815 GC system for the determination of oxygenates in gasoline. Our method offers a simple and rapid testing procedure with accurate and reliable results. Besides，the test the determination of ethers and alcohols in gasolines by gas chromatography. Specific compounds determined are methyl tert-butylether (MTBE), ethyl tert-butylether (ETBE), tert-amylmethylether (TAME), diisopropyl ether (DIPE), methanol, ethanol, isopropanol, n-propanol, isobutanol, tert-butanol, sec-butanol, n-butanol, and tert-pentanol (tert-amylalcohol).
Ethers, alcohols, and other oxygenates can be added to gasoline to increase octane number and to reduce emissions. Type and concentration of various oxygenates are specified and regulated to ensure acceptable commercial gasoline quality. Drivability, vapor pressure, phase separation, exhaust, and evaporative emissions are some of the concerns associated with oxygenated fuels.
This apparatus is applicable to both quality control in the production of gasoline and for the determination of deliberate or extraneous oxygenate additions or contamination.
