النفط الخام الحلو
النفط الخام الحلو Sweet crude oil هو نوع من النفط. بورصة نيويورك للسلع توصـِّف النفط بأقل من 0.5% كبريت بأنه حلو sweet.[1][2]
النفط الذي يحتوي على مستويات أعلى من الكبريت يُسمى نفط خام مر.
يحتوي النفط الخام الحلو على كميات قليلة من كبريتيد الهيدروجين and carbon dioxide. High-quality, low-sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in industrialized nations. Light sweet crude oil is the most sought-after version of crude oil as it contains a disproportionately large fraction that is directly processed (fractionation) into gasoline (naphtha), كيروسين, and high-quality diesel (gas oil). The term sweet originates from the fact that a low level of sulfur provides the oil with a mildly sweet taste and pleasant smell. Nineteenth-century prospectors would taste and smell small quantities of oil to determine its quality.[3]
