Crude Oil

Analyzing Eagle Ford Crude with Lonestar 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 Oil 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.
Detecting Acetic Acid in Crude Oil 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.
Oil Assay - Methanol Analysis 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 Oil 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.
