Gas Chromatograph Webinar Series: How to Calibrate a GC Correctly

by Khadra Helminski, Global Integrated Marketing Manager, Rosemount Gas Analysis, Emerson Automation Solutions

All chromatograph systems provide a comparative measurement where the analysis is a comparison to a known “standard” and the “standard” is the calibration gas. The calibration gas system is critical to the accuracy of the analysis as the gas chromatograph is only as accurate as the calibration gas.

We’d like to invite you to the second webinar in our Gas Chromatograph Webinar Series – “Calibration Gases and How to Calibrate a Gas Chromatograph Correctly.”

This webinar will review how to select a calibration gas, the important features of the calibration certificate, and how to calibrate a gas chromatograph using the calibration gas.

Meeting Bureau of Land Management’s Natural Gas Requirements While Saving Time and Money

 

Jamie Marsden

By Jamie Marsden, Business Development Manager, Gas Chromatographs, Emerson Automation Solutions

Are you faced with the challenge of meeting the measurement accuracy requirements of the Bureau of Land Management (BLM)? And do you have a plan of how you could ensure compliance while staying focused on production rather than gathering samples?

Gas producers must comply with the BLM 43 CFR 3175 regulations, which establish minimum standards for accurate measurement and proper reporting of all gas removed or sold from Federal and Indian (except the Osage Tribe) leases, units, Unit Participating Areas (PAs), and areas subject to Communitization Agreements (CAs).

The BLM rule provides a system for production accountability by operators, lessees, purchasers, and transporters. This rule establishes overall gas measurement performance standards and includes, among other things, requirements for the hardware and software related to gas metering equipment, reporting, and recordkeeping. The BLM rule also identifies certain specific acts of noncompliance that may result in an immediate assessment and provides a process for the BLM to consider variances from the requirements of this rule.

There’s a way to be compliant with these regulations while reducing measurement errors and the costs of complying with 40 CFR 3175. Simplifying the process can allow you to focus on production rather than gathering samples. The approach is to use the appropriate natural gas chromatograph (GC). For example, Emerson’s Rosemount™ 370XA and 770XA GCs reduce BTU measurement errors often found with spot sampling. The online sampling of field-mounted GCs eliminates the need for personnel to frequently travel to the Facility Measurement Point (FMP) to pull a sample; saving man hours and travel costs. The 370XA is ideal for C6+ applications while the 770XA is ideal for C9+ applications or where hydrocarbon liquids may be present. Both are compact in design, don’t require a shelter, offer low utility gas consumption, and operate on 24 Vdc. This makes them perfect for remote locations.

The 370XA and 770XA provide analysis per requirements of the Gas Processors Association (GPA). They offer fully pre-engineered custody transfer application solutions that provide accurate and repeatable measurement analysis for the heating value of natural gas (§§3175.118).

In addition, the use of an advanced GC software solution such as the Emerson MON2020 further simplifies compliance and reduces maintenance and operation costs. The software gives you complete control of the GC either locally or remotely. You can store 88 days of analysis results, over a year of final calibration results, and over 1,700 chromatograms. The analysis report provides heating value and relative density.

In total, a straightforward evaluation of technologies can save natural gas operators both time and money. Managing compliance using the appropriate gas chromatograph not only meets BLM 43 CFR 3175 regulatory requirements, it saves substantial time and money while allowing the user to employ a familiar, proven, and highly accurate technology for the job.

The Right Gas Chromatograph for the Job

By Bonnie Crossland, Product Marketing Manager – Gas Chromatographs, Emerson Automation Solutions

Balancing the right level of gas chromatograph (GC) performance and cost for individual applications and locations within a plant or installation is key for many operators. Increased pressure to optimize processes is driving an increased demand for accurate and timely composition analysis for use in process control and product quality assurance. To continue to meet these demands, Emerson’s Rosemount 1500XA process gas chromatograph adds new enhancements to provide faster compositional feedback and complete, high-resolution analysis, helping operators optimize product specifications and maximize throughput.

Rosemount™ 1500XA Process Gas Chromatograph

The Rosemount™ 1500XA process gas chromatograph is designed for refining, petrochemical, power, and environmental applications where selected components in gaseous or liquid streams must be precisely monitored on a continuous basis. The recent enhancements to the 1500XA enable parallel chromatography, offering oven capacity for up to eight chromatograph valves and four detectors, two of which can be flame detectors. Depending on the application, the 1500XA can include flame ionization or flame photometric detectors for measurement of compounds in the parts-per-billion ranges, or thermal conductivity detectors (TCD) capable of handling applications with parts-per-million measurement requirements.

The 1500XA, like the entire Emerson GC family, is characterized by ease-of-use, ruggedness, and reliability. Emerson is currently the only online GC supplier to offer a lifetime warranty on chromatograph valves. The valves are rated for more than five million operations before repair, which involves simply replacing the diaphragms and can be done easily on-site.

With its numerous valves and detectors, the 1500XA can take a complex analysis application and break it down into smaller, simpler analysis blocks. These blocks are then run in parallel, reducing analysis time and providing faster, easier maintenance and troubleshooting, as well as straightforward data analysis. A complex analysis that may have previously taken 20 minutes may now only take 10 minutes, allowing quicker response to process changes. The 1500XA’s concurrent analysis can be used to reduce the time between analyses by running them at offset times. This can increase the number of analyses within a set time period.

Emerson’s MON2020 software allows the 1500XA to operate completely unattended while making analyzer configuration, maintenance, and data collection easy, either locally or remotely. With intuitive dropdown menus and fill-in-the-blank tables, even new users can quickly navigate through the software.

Since many users are looking for cost-effective and reliable GC solutions, the 1500XA with parallel chromatography and concurrent analysis capabilities more than fulfills that need. When combined with the 370XA and 700XA gas chromatographs, the 1500XA rounds out the widest single selection of gas chromatographs on the market. This makes the Emerson GC family flexible, and reduces costs for integrators and users alike. Used in a wide range of industries, the Emerson GC line allows users to get precisely the performance they require in each location and application while maintaining the same easy-to-use interfaces, the unique software capabilities, and common maintenance requirements.
