While online process analytics flourishes, often it is laboratory analysis which defines final product quality and which provides the yardstick against which analyzer performance will be measured. The lab ensures appropriate quality control for refinery finished products and individual refinery finished products and individual unit operations and provides necessary laboratory support for activities such as operations analysis. In other applications, such as custody transfer, the laboratory analysis becomes the defining arbitrator regarding product specifications Custody transfer occurs when fluids or gases are exchanged between parties, and are based on contractual agreements regarding product quality and volumes. Payment is usually made as a function of the amount of fluid transferred, but in many cases product quality factors such as chemical composition or physical properties may affect the final price. As a result, it is imperative that the fluid be sampled, analyzed and product quality determined. Automating the sampling process reduces the likelihood of human error biasing the sample, and improves data acquisition and retention of chain of custody information. Automated samplers may be used to obtain spot samples or composite samples. Spot samples are taken at one time at one point, while composite samplers are acquired over time and provide a means to determine time or flow weighted averages. The design and implementation of sampling systems requires significant experience and a thorough understanding of design requirements. Requirements for proper sampling will be discussed, as well as automated systems for both spot samples and composite sampling
Optical spectroscopy is a favored technology to measure chemistry and is ubiquitous in the hydrocarbon processing industry. In a previous paper, we focused on a generic, machine-learning approach that addressed the primary bottlenecks of mustering data, automating analyzer calibration, and tracking data and model performance over time. The gain in efficiency has been considerable, and the fact that the approach does not disturb any of the legacy (i.e., no changes or alterations to any analyzer or software in place) made deployment simple. So, we have set the standardized procedure for doing calibrations that adheres to best practices, archives all data and models with easy access in mind, and delivers the models in any format. What remains is to assess the speed of processing and the quality of the models. To that end, a series of calibration experts were tasked with model optimization, restricting the work to selecting the proper samples to include in the computation and setting the number of factors in PLS. The amount of time and the quality of the models were then compared. The automated system performed the work in minutes rather than hours and the quality of the predictions at least matched the best experts and performed significantly better than the average expert. The conclusion is that there is a large amount of recoverable giveaway that can be avoided through automation of this process and the consistency it brings to the PLS model construction.

Removing any moisture from the gas is an important step in sample gas conditioning. To achieve this, suitable coolers are applied to reduce the gas temperature below the dew point in order to condense the moisture. To secure a reproducible analysis result the dew point must remain as stable as possible even when the ambient temperature fluctuates. The required cooling capacity depends on the temperature fluctuations at the sampling site (which may vary over the course of the year), the specific material combination for the heat exchanger to meet the sample gas composition and the energy-efficient operation of the cooler. The coolers are primarily electric gas coolers, either thermoelectric or compressor style, the selection determined by the requirements or the operating conditions. Replaceable heat exchangers in a variety of material compositions and helpful accessories and monitors complete the product portfolio. Especially in hazardous locations, these options can be simplifying the installation and reduce the effort for electrical connections.
Emissions data warehousing presents special challenges that don’t meet the typical strengths and applications of a plant control system. To maximize data integrity and ensure compliance, manufacturers are more frequently looking to Data Acquisition and Handling Systems (DAHS), such as NetDAHS Edge supplied by Cemtek KVB Enertec. The DAHS is built from the ground up to collect air emissions data and perform all calculations to prove compliance with all air permit conditions. The DAHS infrastructure also provides long term data storage and usability functions to allow the facilities to access data, perform analysis, and many other features.
Excimer UV Fluorescence (EUVF) is a relatively new technology that has demonstrated an unsurpassed linear dynamic range than that achievable with conventional UV Fluorescence analyzers. This has allowed it to successfully meet sulfur measurement and calibration requirements of regulatory standard US EPA 40 CFR Part 60.18 Subpart Ja, using a single valve and calibration standard over the entire measurement range.
EUVF has also demonstrated excellent sensitivity making it ideal for accurate, low-level measurement of sulfur in fuels, to meet required reductions in global emissions. Standards such as the American Tier III, European Euro 6 and the Indian Bharat VI set quantitative limits on permissible amounts of specific pollutants that can be released during combustion where emission of oxides for both Sulfur and Nitrogen are regulated. Data will be presented showing successful compliance to repeatability requirements within limits set by these standards.
EUVF has also been shown to exhibit unsurpassed nitrogen interference, making it the choice for precise measurement of low sulfur levels required by these regulations, particularly when high nitrogen content is present. EUVF is now a proven technology with ATOM Instrument being the only manufactured brand incorporating this superior version of UV fluorescence in their analyzers.
The presentation will address how smart digital sensors in combination with digital transmitter outputs enable advanced diagnostics and quick calibration of your pH, ORP, conductivity, and oxygen sensors in the analyzer shop or lab. Areas covered include: Analog vs. digital communication with liquid analytical probes; tools for simple pre-calibration of smart digital sensors in the shop or lab; enabling better sensor management with continuous diagnostics monitoring through transmitter outputs; and, maintenance cost reduction with simpler installation and replacement.
