H2S, H2S in Crude Oil, H2S Analyzer, Safety ABSTRACT Measurement of hydrogen sulfide (H2S) is a critical practice for quality control and safety purposes. Without precise quantification of H2S in a process, efficient processing of crude oil is not possible. To maintain safety when transporting crude oil and condensate, measurement of the H2S content is vitally important. This is an in-plant Hydrogen Sulfide in Crude Oil Managing H 2 S is a challenge at every stage of hydrocarbon production, refining and transportation. Crude oil considered to contain high levels of H 2 S may be refused by the operator and devalued by the customer. A primary objective for testing and treatment of crude oil is the reduction of H 2 S content in the liquid The 205L Portable Lab H2S in Crude Oil Analyzer is a quick and accurate lab analyzer for the analysis of H2S in crude oil. The analyzer features the Sample Transfer Stripper (STS) with exclusive ASI Membrane Technologies and the rateometric-colorimetric H2S detection technology. The Canadian Crude Quality Technical Association (CCQTA) “H2S Measurement in Crude” project was established to adapt and validate an existing portable measurement device, currently used in the internationally accepted IP570 method (measurement of H2S in fuel oils), to accurately measure both liquid and vapor phase hydrogen sulphide in crude petroleum. Difficulty of quantifying H2S in crude oil • Crude oil is compositionally complex • Aromatics make quantification difficult • Common problematic components: • SO2, ethyl-mercaptan, methyl-mercaptan and other sulfur compounds • Crude compositional changes not uncommon The H2S Analyser and Vapour Phase Processor (SA4015-0) are compact bench-top instruments, used to measure the total hydrogen sulphide (H2S) content of fuel oils, such as marine residual fuels, distillates and petroleum blend stocks. The H2S Analyser can measure H2S concentrations from 0 to 250 mg/kg (ppm) in the liquid phase. Sulfur species compounds detection in crude oil, natural gas, fuels, refined products and chemicals. Intertek laboratories detect and trace level measure sulfur species in petroleum, petroleum-refined products such as fuels and petrochemicals, natural gas, and polymers. Sulfur (sulphur) species components are characterized and detectable to ultra-trace levels. The laboratories measure total sulfur content, elemental sulfur, and identify sulfur species to trace levels. Sulfur analysis labs

Mercaptans and hydrogen sulfide in crude oil as per ASTM D3227 and UOP163 1/22/2016. In the refining process of crude oil, sulfur compounds are present throughout the entire boiling range of the hydrocarbons. In order to prevent corrosion of pipes and meet the specifications for the final products, various desulfurization treatments are used. Hydrogen Sulfide Scavengers Organic Bases ÊAdvantages: ÊFast reaction ÊNo sodium ÊOil soluble/dispersible ÊDISADVANTAGES: ÊReaction is Reversible ÊWeak acid/base equilibrium ÊNot specific for H 2S Typically Amines (e.g. MEA) H 2S + Neutralizer Salt Hydrogen sulfide testing measures H2S content in hydrocarbon products, including petroleum, fuels, asphalt, gases and chemicals. Testing for H2S is available for the entire hydrocarbon supply chain, from crude oil production to petroleum refining, fuel and refined products transportation, blending, and storage. 1.1 This test method covers the detection of hydrogen sulfide in liquefied petroleum (LP) gases. The sensitivity of the test is about 4 mg/m 3 (0.15 to 0.2 grain of hydrogen sulfide per 100 ft 3 ) of gas. 1.2 The values stated in SI units are to be regarded as standard. ASTM's petroleum standards are instrumental in the evaluation and assessment of the physical, mechanical, rheological, thermal, and chemical properties of crude oils, lubricating grease, automobile and aviation gasoline, hydrocarbons, and other naturally occurring energy resources used for various industrial applications. The sensitivity of the test is about 4 mg/m 3 (0.15 to 0.2 grain of hydrogen sulfide per 100 ft 3) of gas. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. With our H2S in crude oil analyzer, the ability to analytically quantify H2S in light, medium & heavy crude oil and condensate is greatly enhanced with the Sample Transfer Stripper (STS) utilizing exclusive ASI Membrane Technologies and rateometric-colorimetric detection technology. This principle of operation is described in various ASTM methods including D4084-82, D4468-85, and D4045-81.

Hydrogen Sulfide management in Crude Oil . Managing hydrogen sulfide (H. 2. S) is a challenge at every stage of hydrocarbon production, refining and transportation. Hydrogen sulfide is highly toxic, reduces product value, compromises environmental and safety compliance, corrodes infrastructure, produces noxious odours and has other detrimental effects.
