ما هو زيت التنقيط؟
زيت التنقيط هو سائل هيدروكربوني طبيعي يتكثف من الغاز الغني المنتج من آبار النفط والغاز. يتكون بشكل أساسي من هيدروكربونات سلسلة الكربون المنخفضة، لا سيما البروبان، البيوتان، و البنتان، مما يجعله مصدرًا قيمًا للطاقة والمواد الخام.
التكوين والاسترداد:
عندما يتدفق الغاز الطبيعي من البئر، يحمل كمية كبيرة من مكونات الهيدروكربونات الثقيلة، أهمها الهيدروكربونات السائلة. عند تبريد هذا الغاز ومعالجته، تتكثف هذه المكونات الثقيلة وتنفصل عن تيار الغاز. يُعرف السائل الناتج باسم زيت التنقيط أو المكثف.
خصائص زيت التنقيط:
يُظهر زيت التنقيط العديد من الخصائص الفريدة التي تميزه عن السوائل الهيدروكربونية الأخرى:
