Latest Applications SciMed Applications Testing the quality of biodiesel What is biodiesel? Biodiesel represents a popular, renewable alternative to traditional petroleum-derived fuels. Its carbon neutral footprint, sustainability and economic viability have brought it sharply into consideration as a substitute and supplement for middle distillate fuels. Biodiesel is synthesised by transesterification of triglycerides into mono-alkylated, fatty esters and glycerine. Why is biodiesel quality control testing important? In the early 2000s, insufficient regulation on biodiesel production led to multiple mechanical issues, such as engine clogging. As biodiesel is less stable than petrodiesel, it is more vulnerable to oxidation. The products of this…
The study of metals and metal alloys can be achieved using thermal analysis techniques to measure properties such as corrosion, oxidation, reduction, expansion, transitions and magnetic properties.
In order to develop new materials that have desired properties, it is essential to evaluate the materials under various atmospheric environments. The infrared heating high-temperature attachment Reactor X has a corrosion-resistant sample chamber separated from the heater section, so it can be used to perform high-temperature XRD measurements under various atmospheres, such as hydrogen, ammonia, high humidity and so forth. Using Reactor X with a 2D detector capable of high-speed XRD measurement, it is possible to investigate in detail rapid phase transitions under heating in various atmospheres.
As next-generation ultrahigh-density magnetic recording media, granular thin films in which metal microparticles are dispersed have been a focus of attention. Among these films, the regular phase (tetragonal crystal) of FePt has a particularly high magnetic anisotropy as well as good corrosion and oxidation resistances, so it is expected that it will be applied to actual devices. However, the irregular phase (cubic crystal) is created at the same time, depending on the filmforming conditions. For this reason, a technique to distinguish these crystalline phases at the nanoparticle and thin film level is required. Using the in-plane X-ray diffraction method, in…
Crude oil is raw material for petroleum products and contains sulfur in concentration from 0.5 mass% to 5.0 mass% typically. Residual fuel oil and high-sulfur diesel fuel are mainly used for boilers and burners, agricultural machines, and long-distance mass transportation means, such as vessels and diesel locomotives of rail road, equipped with large engines. Sulfur compounds in petroleum cause various harmful influences such as air pollution, metal corrosion and catalyst degradation. Therefore, sulfur concentration of crude oil and high-sulfur fuels is monitored or controlled in refinery and production processes in the petroleum industry. X-ray fluorescence (XRF) spectrometry has been used…

Water-methanol-oil mixtures in varying compositions are used as additive in internal combustion engines. Here, water injection, also known as anti-detonant injection systems (ADI), is used to spray water or a water/methanol mixture into the fuel/air mixture in order to cool the introduction system avoiding premature ignition of the fuel. This leads to improved behavior in terms of engine knocking and compression ratio in engines of aircrafts and racing cars. Results are increased power and fuel efficiency, improved power output for short duration such as increase of thrust of jets during takeoff, and reduction of NOX and CO emissions by decreased…

Water within power plants, and particularly boiler feed water, is subject to strict analytical control. Organic impurities in the boiler feed water can easily oxidize under high pressure and high temperatures and may lead to the formation of corrosive organic acids and carbonic acid. State-of-the-art feed water production therefore uses reverse osmosis or ultrafiltration membranes and ion exchangers to reduce and control the corrosion potential of the final feed water. The condensate return has to be checked for TOC levels as well to monitor for contamination, for example contamination caused by leakages in the steam pipes or heat exchangers. In…
Electroplating baths are widely used to deposit a metal coating on a conductive surface by immersion of the objects into a bath solution and application of an electric current. The purpose of this can vary in a wide range that includes decorative silver, gold, or palladium finish on jewelry or the enhancement of physical properties such as corrosion prevention, conductivity, hardness, or durability changes to materials. Manufacturers of plating baths need to establish optimum specifications for their plating solutions and must take action to maintain their formulations and to prevent problems related to improper levels of bath constituents and contaminants….
Crude oil always contains salt, either dissolved in water droplets or in form of crystalline salt. Since salt contents can cause problems by forming precipitates, accelerating corrosion processes or catalyst degradation during the refining process, crude oil is undergoing a desalting process. By-product of this process is water of high salt concentrations up to 26 % of mostly NaCl (smaller amounts of CaCL2 and MgCL2), so-called brine. Brine, as a product of petrochemical industry, is a starting material in other industries, e.g. as refrigerating fluid, in water purification or de-icing processes. One of the quality criteria for the further use of…
