A water monitoring system with a new chemical sensor for oil contamination was developed. The sensor had an organic polymer film on a quartz crystal microbalance (QCM). The organic film was a hydrocarbon polymer and had high affinities for the organic compounds of petroleum products such as gasoline, kerosene, diesel oil and fuel oil. The monitoring system was composed of a sampling part, a purging part, a humidity control part and a sensor part. The oil in contaminated river water could be detected whose threshold odour number (TON) was less than three. The detecting time was less than 5 min depending on the oil kindness. This system was tested using artificially contaminated river water with the oils, to be found that the sensitivity was kept steady for longer than 6 months with 400 detections of diesel oil and heavy oil. Moreover, the oil kind could be discriminated with only one sensor device by analyzing the desorption response curves obtained by flowing a clean air on the sensor instead of the purging air.

Oil contamination in the Storm water has been generally overlooked, even though it causes major environmental pollution and is a substantial threat to all the species in the ecosystem. Likewise, the treatment of oil-contaminated Storm water in public areas and general industries, especially in airports, has largely been ignored. Airports are known as one of the most potent oil contamination contributors through the jet fuel that pollutes the local waterways and Storm water. However, little information regarding the specific actions taken to treat the Storm water contaminated with jet fuel oil in airport facilities, is available.The objective of this paper is to discuss the Storm water management that using the oil-water separator system in airports contaminated with oil. Specifically, this paper highlights the contaminants of Storm water run-off from airports and the oil-water separator system in airports.The use of a corrugated plate interceptor (CPI) for Storm water management in airports was discussed.The success in treating Storm water largely depends on the improvement of infrastructure, the capturing of pollutants and nutrients from the Storm water flows, in addition to the use of wetlands to improve the ecology and water quality of streams and rivers. Incorporating an oil-water separator system into the Storm water treatment system in the airports setting is quite significant since the airport is known for its large and paved areas containing oil, grease or jet fuel.The treatment of the airports Storm water contaminated with oil, grease and jet fuel could significantly reduce the contamination for a cleaner environment. The CPI can be used to separate the oils from the water and then retains the oils safely until removal.

We have used high spatial resolution imaging secondary ion mass spectrometry (SIMS) to differentiate mineralogical phases and to investigate chemical segregations in fluidized catalytic cracking (FCC) catalyst particles. The oil industry relies on heterogeneous catalysis using these catalysts to convert heavy hydrocarbon fractions into high quality gasoline and fuel oil components. Catalyst performance is strongly influenced by catalyst microstructure and composition, with different chemical reactions occurring at specific types of sites within the particle. The zeolitic portions of the particle, where the majority of the oil conversion occurs, can be clearly distinguished from the surrounding silica-alumina matrix in analytical SIMS images.The University of Chicago scanning ion microprobe (SIM) employed in this study has been described previously. For these analyses, the instrument was operated with a 40 keV, 10 pA Ga+ primary ion probe focused to a 30 nm FWHM spot. Elemental SIMS maps were obtained from 10×10 μm2 areas in times not exceeding 524s.
