Abstract:
Petroleum products are widely used throughout transportation and industrial manufacturing sectors, but are known to be associated with causing various health issues due to their emitted fumes. According to statistical data, there are multiple cases of deaths reported which were attributed to hydrocarbon gasses and vapors. Measurement of the vapor pressure of petroleum-derived products is essential for obtaining an indication of how a fuel will perform under different operating conditions. Various government agencies regulate the specification of petroleum products and maximum vapor pressure limits are legally mandated in certain areas for air pollution control. Acquiring accurate and reliable vapor pressure measurements is important for ensuring the proper transport and storage of petroleum products as well.The K24870 Automatic Microscale Vapor Pressure Analyzer can determine the total vapor pressure exerted in a vacuum by air-containing, volatile, liquid petroleum products, automotive spark-ignition fuels, hydrocarbons, and hydrocarbon-oxygenate mixtures in accordance with ASTM D5191 and D6378. This newly designed instrument utilizes the Triple-Expansion Principal for vapor pressure determination, which involves the volumetric expansion of tested samples by X times in three steps. By taking the difference of the total pressure after final expansion and the partial pressure from dissolved air, the vapor pressure of the sample is calculated. This innovative Microscale Vapor Pressure Analyzer is fully automated and only requires a small sample size of 1 mL for testing and 2.5 mL for rinsing. The instrument is easy-to-use and is the ideal tool for vapor pressure determination to avoid safety hazards and health implications and promote proper petroleum management.
