    H2S in Oil Industry

        Introduction This article impacts on human health caused by exposure to hydrogen sulfide (H2S) associated with crude oil and natural gas development. It begins with a brief background on hydrogen sulfide, its presence in oil and natural gas, and possible emission sources from various oil and gas operations. epidemiology, and industrial health publications, as well as of sources from regulatory and environmental agencies, that addresses human health impacts from exposure to H2S. Many recommendations established to protect human health are based on crude exposure estimates or on extrapolation from animal studies. The USA government does not regulate ambient H2S levels, but many states do. Three states conduct routine monitoring of ambient H2S levels, and…

    Removing H2S from Oil

        1. INTRODUCTION Sulfur compounds exist in various light oils made from petroleum. Such as mercaptan, hydrogen sulfide, which cause foul odors and deteriorate the finished products. In addition, due to their acidity, they are corrosive to metals, which is harmful for storage and usage of oil products. Therefore, it is necessary to remove them. In the refining industry, an aqueous base such as sodium hydroxide or ammonia is employed fulfilling the purpose. Although its effectiveness and the low cost of fresh caustic are the reasons for its widespread use, the aqueous base especially sodium hydroxide always causes some problems. Such as spending many caustic materials, and discarding lots of hazardous waste. So environmental agencies around the world have…

    Components of Natural Gas other than Methane

          Natural gas is a mixture of methane, with lower amounts of other hydrocarbons and other substances. These other constituents modify the physical and chemical characteristics of natural gas, for example, inert gases make the natural gas heating value lower. The substances that can be in natural gas are: • Carbon dioxide • Nitrogen • Hydrogen sulphide Heavier hydrocarbons which can be separated to give condensate (gasoline) Water vapour is always contained in natural gas. Carbon Dioxide (CO2) The content in CO2 varies from traces to very high amounts. It forms from the reaction of field water with silicates and carbonates. Even a minimal presence of carbon dioxide in natural gas saturated with water forms…

    Crude Oil Sweetening and Stabilization

    why crude oil is stabilized? Once degassed and dehydrated–desalted, crude oil is pumped to gathering facilities to be stored in storage tanks. However, if there are any dissolved gases that belong to the light or the intermediate hydrocarbon groups it will be necessary to remove these gases along with hydrogen sulfide (if present in the crude) before oil can be stored. This process is described as a ‘‘dual process’’ of both stabilizing and crude oil sweetening. In stabilization, adjusting the pentanes and lighter fractions retained in the stock tank liquid can change the crude oil gravity. The economic value of the crude oil is accordingly influenced by stabilization. First, liquids can be stored and transported to the market…

    Sour Gas Sweetening

    تحلية الغاز الحامضي Sour Gas Sweetening أن الغاز الطبيعي يحتوي عادة ً على بعض الشوائب impurities مثل كبريتيد الهيدروجين H2S وثاني أوكسيـــــد الكربون CO2 والهيدروكاربونات الثقيلة مثل المركبتان. تعرف هذه المركبات بالغازات الحامضية Acid gases.  أما الغاز الطبيعي الحاوي على H2S أو مركبات كبريتية أخرى مثل CS2 – COS والمركبتان يسمى الغاز الحامضي Sour Gas ، أما إذا كان يحتوي على CO2 فقط فيسمى بالغاز الحلو Sweet Gas.  وعادة ً يجب إزالة كل من H2S – CO2 لمنع حدوث مشاكل التآكل وزيادة القيمة الحرارية للغاز.  أن تحلية الغاز الطبيعي Sweetening هي أحد أهم الخطوات في معالجة الغاز ، وترجح أهمية تحلية الغاز للأسباب التالية:  1. المخاطر الصحية: يمكن تحسس غاز…
