Boiling point characteristics for crude oil are used by the refineries to characterize the raw product so it can model the end product closer to specs. More accurate and precise data for the entire crude oil range translates into better profit for the refinery with very little product give-away while still meeting stringent product specifications. Combining High Temp SIMDIS with DHA Front-End delivers better precision data for the whole crude as such, resulting in more accurate cut point determinations, and a better product value optimization. This white paper compares results from High Temp SIMDIS versus HighTemp SIMDIS/DHA Front-End analysis.
The distillation characteristics, i.e., volatility, of hydrocarbons significantly impact the safety and performance of end-products, particularly with fuels and solvents. The boiling range gives information on the composition, the properties, and the behavior of the fuel during storage and use. This paper discusses the benefits of using a process application of the ASTM D7345 test method to provide real, online distillation analysis to prevent product giveaway and reprocessing, and to meet tight blending specifications at the most reasonable cost.
Tight blending specifications are required to make gasoline at the most reasonable cost. On-line analysis provides crucial information to prevent product giveaway and reprocessing. This paper presents a technology discussion for total sulfur analysis and determining distillation boiling points in the gasoline blender, including:
Total sulfur is an important parameter to monitor and control intermediates and/or final products for process optimization and blending in refineries, pipelines, and petrochemical plants. An online sulfur analysis can be deployed at many points in the process and provides the means to monitor conversion processes to produce the most valuable products without giveaway.
Standard Cambridge Viscosity high pressure viscometers such as the VISCOlab PVT are rated for continuous service at pressures from ambient to 20,000 psi and temperatures from ambient to 190°C. The heart of these products is Cambridge’s SPL-440 sensor. This sensor provides continuous measurements, in real time, at an accuracy ranging from 1% at ambient conditions to 5% at the extreme conditions. This paper details:
Viscosity is one on the most critical measures of product quality for virtually every refinery product. New developments in viscosity measurement are enabling refineries to realize significant improvements in production quality, cost, and output. These new developments and their respective benefits are discussed in this paper.
