Amine Detection with LonestarA variety of amines may be found in oil and gas, both as constituents and as by-products of processes to remove H2S and/or CO2. Lonestar can detect the presence of amines in both crude oil and water backgrounds, allowing in-situ monitoring of concentrations throughout the treatment process. TOPGUARD is a trademark of Baker Hughes Incorporated.

Analyzing Eagle Ford Crude with LonestarThe Eagle Ford Shale Play in Southern Texas is currently (October 2013) the second most productive oil field in the United States, producing some 1.07 million barrels per day . However, after extraction, hazardous levels of hydrogen sulfide may be present in the crude. H2S can be contained or removed with triazine-based scavengers, but leftover scavengers and the reaction byproducts can themselves cause corrosion and fouling downstream. Using the Lonestar portable analyzer, excess scavenger content in crude after treatment can be identified and quantified. For more details, see the Analysis of H2S Scavengers page.

Analysis of Organic Chlorides in Crude OilOrganic chloride contamination in crude oil can cause hydrochloric acid to be formed during hydrotreating. The hydrochloric acid then corrodes equipment through accumulation, and can be particularly damaging in crude tower overhead systems. For this reason, organic chloride levels should ideally be kept below 1ppm.

Carbonyl Sulfide in PropaneCarbonyl sulfide is a contaminant in propane that can form corrosive hydrogen sulfide when it undergoes hydrolysis. This process has been implicated in corrosion and compliance-testing failures in the LPG industry. Using Lonestar, the presence of carbonyl sulfide in propane can be quickly identified.

Detecting Acetic Acid in Crude OilAcetic acid is used to prevent the formation and precipitation of naphthenate salts during crude oil separation and desalting. However, excess acetic acid can lead to high corrosion rates (~100mils/year compared to a normal rate of around 5mils/year), and can generate a high chemical oxygen demand in waste water treatment plants. There is therefore a need for rapid, on-site measurement of acetic acid levels.

Book Conservation Using Lonestar Portable AnalyzerAs stored books age they generate and release volatile organic compounds (VOCs). It has been shown that the release of certain emitted VOCs (such as furfural) is correlated to the extent of paper degradation in a book. The Lonestar portable gas analyzer can be used to detect VOCs associated with paper degradation and aid in the conservation of antique books, manuscripts and other paper based artifacts.

Detecting sulfites and SO2 using LonestarThe Lonestar portable analyzer is able to detect whether Traditional Chinese Medicines (TCM), herbal remedies and alternative medicine products contain sulphites by detecting the presence of trace amounts of sulfur dioxide (SO2). Sulfite sensitivity affects many people making the presence of sulfites in herbal medicines a common concern for consumers.

Detection of Metaldehyde in Water Using LonestarLonestar offers rapid detection and monitoring of metaldehyde at concentrations low enough to meet the European and UK regulations for pesticides in drinking water. Lonestar can be operated on site by non-specialist personnel to monitor water for metaldehyde in only a matter of minutes.

Dimethyl sulfate gas detection using LonestarLonestar can be used as a dimethyl sulfate (DMSO4) gas monitor for ambient air. DMSO4 is a highly toxic but commonly used industrial methylating agent. Lonestar can continuously sample air and raise the alarm if the concentration of DMSO4 rises above a specified threshold level.

Pharmaceutical waste water analysisWaste water treatment by bacteriological biodegradation is used to treat waste water streams (e.g. pharmaceutical, environmental bioremediation). Excesses of some solvents in the waste water can poison the microbes - reducing their efficiency. Consequently there is value in being able to quickly measure concentrations of these critical solvents so they can be pretreated/diluted to protect the bacteria.

Oil Assay - Methanol AnalysisMethanol in crude oil impacts water treatment systems in refineries because bacteria involved in cleansing the water preferentially break down methanol, leaving hydrocarbons and toxins untreated. Methanol is miscible in water, so is present in the desalter effluent. Refineries often choose to cut crude runs rather than risk a "bug kill" - a large upset that would require major remediation and could cause violation of environmental legislation, permit excursions or future penalties.

Analysis of Scavengers for Sulfide (H2S) Removal from Crude OilTriazine compounds are commonly used as scavenger chemicals to remove hydrogen sulfide (H2S) from crude oil, in a process sometimes called "stripping".  These triazine-based additives are often present in excess of the levels required to remove the H2S. The excess triazine, together with the by-products of the scavenging reaction with H2S, may cause corrosion and fouling in downstream equipment. Consequently, there is value in petroleum processors being able to quickly measure excess concentration of scavenger before custody transfer.

Rapid Detection of Geosmin, Fuels and Pesticides in Water SuppliesMonitor drinking water supplies to detect geosmin, fuel (diesel/gasoline/petrol), metaldehyde and other chemical contaminants. Using Lonestar analyzers, utilities can mitigate contamination incidents and avoid taste/odor complaints. Combat tightening regulations and terrorist threats, reduce the costs of supplying consumers, industry and food manufacturing. See the instrument work in the video.

Benzene Analysis and DetectionLonestar is a portable gas monitor capable of rapid and accurate benzene analysis. Lonestar can monitor and detect benzene even in a complex background matrix that includes toluene, xylene and other gases (volatile organic compounds, VOCs) that commonly cause false alarms in other detectors.

Rapid Analysis of 4 Methyl Imidazole (4-MEI)The Lonestar Analyzer can detect and quantify 4-Methyl-Imidazole (4-MEI, also sometimes called 4-MI) within 15 minutes, in a range of backgrounds, including caramels and soy sauce. Deploy Lonestar to ensure compliance with Proposition 65 and improve plant throughput and productivity.

Residual Solvent Monitoring with LonestarLonestar is a powerful, easy to use analyzer for accurate, real time identification and monitoring of Class 1, 2 and 3 residual solvents as outlined by The International Conference on Harmonisation (ICH) guidance documents and the United States Pharmacopeia (USP).

Dimethyl sulfate gas detection using LonestarLonestar can be used as a dimethyl sulfate (DMSO4) gas monitor for ambient air. DMSO4 is a highly toxic but commonly used industrial methylating agent. Lonestar can continuously sample air and raise the alarm if the concentration of DMSO4 rises above a specified threshold level.

Explosive calibration standards (DMMP, MS, DMNB, DNT)The OVG-4 is the fastest, safest and easiest way to test and traceably calibrate sensors and instruments for the detection of chemical warfare agents and explosives.  With our CWX package we provide an OVG-4 and four permeation tubes with common chemical warfare simulants and explosive taggants (DMMP, MS, DNT and DMNB).
