The crude oil assay is the collection of the results of physical tests that are performed to determine the key properties (boiling point, density, viscosity, heteroatom contents, acid number, etc.) of crude oil and its fractions. It is the procedure based on laboratory and pilot plant testing for determining the general distillation and quality characteristics of crude oil. Crude oil assay is important for determining the value and processability of crude oil. This is the preliminary step before processing the crude oil in the refinery. . In order to utilize the crude oil assay data, it is necessary to understand the results and significance of some of the laboratory tests.

Determination of Ethylene Glycol in Used Engine Oil by Headspace-Gas Chromato...PerkinElmer, Inc.
The presence of ethylene glycol in used motor oil is an indication of antifreeze coolant leakage into the crankcase of an internal combustion engine, thus predicting engine-wear problems. Several options for the determination of glycols currently exist, including colorimetric tests which are easy to perform, but subjective in interpretation and not particularly sensitive, fast or cost effective. Gas chromatography (GC) can also be used for analysis, but the ethylene glycol is difficult to detect and quantify due to its low molecular weight, low volatility and high polarity. Ethylene glycol chromatographic
peak shape is often difficult to control and carryover can be a problem. Injecting used engine oil directly into a gas chromatograph for the determination of ethylene glycol introduces high molecular-weight oil and non-volatile components into the injector and the column. Consequently, the chromatography is very long, the column lifetime is shortened and the sample throughput is low, since high boiling components from the oil matrix must elute before the next injection. ASTM Method D4291-98 specifies diluting the oil sample with hexane, extracting the glycol into water and analysis by GC. This is a very labor intensive sample preparation procedure and an unforgiving chromatographic method, whereby water and the polar analyte are injected on-column. An alternative to ASTM Method D4291-98 is investigated here, which involves a very simple in-situ derivatization technique that allows the glycols to be made more volatile and less polar.
Headspace (HS) extraction is used to isolate the glycols from the complex sample matrix and inject into a gas chromatograph for rapid separation and quantification without the oil matrix. The result is a rapid, high-throughput method capable of analyzing hundreds of samples per day for ethylene glycol and propylene glycol in motor oil.

The LLT Clarifier is a new short retention time trayless clarifier developed at Audubon Sugar Institute in Louisiana. Since 2009, many sugar mills in different parts of the world have implemented the technology with excellent results. The main differences of the LLT, compared to other clarifiers, are that it comes with an integrated flash trough and juice turbulence reduction devices (TRDs). The built-in flash trough eliminates the necessity of an external flash tank; provides more degassing area compared to the latter; occupies less space; requires less steel, and avoids the need of foundations and support structures. The juice distribution system of the LLT Clarifier comprises a number of feed pipes uniformly distributed over the cross-sectional area. The exit points of the pipes come installed with the TRDs that effectively reduce flow momentum and eddies. As a result, the LLT Clarifier is capable of providing shorter retention times, lowers sucrose losses and provide juice of high quality compared to other clarifiers available in the industry. The purpose of this presentation is to explain in more detail the technical aspects of the LLT Clarifier.
