Step-by-step process flow:1️⃣ Feed Preheating – Raw naphtha is heated using heat exchangers.2️⃣ Mixing with Hydrogen – Hydrogen is added to the feed.3️⃣
Operator Zone – Oil & Gas Interview Questions Latest Questions
🔹 The operating conditions vary based on feed composition, but generally:✔ Temperature: 280–400°C (536–752°F)✔ Pressure: 30–60 bar (450–900 ...
Sulfur removal is critical because:✔ Protects reformer catalyst – Sulfur poisons the Pt-based catalyst in catalytic reforming.✔ Reduces SO₂ emissions – Prevents air ...
The key reactions in the NHT unit are:✔ Hydrodesulfurization (HDS) R−S+H2→R−H+H2SR-S + H₂ → R-H + H₂SR−
the catalyst used in NHT is typically Co-Mo (Cobalt-Molybdenum) or Ni-Mo (Nickel-Molybdenum) on an alumina base.✔ It promotes hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) reactions.✔ Helps convert ...
The Naphtha Hydrotreater (NHT) Unit removes sulfur, nitrogen, oxygen, and metal impurities from naphtha using hydrogen under high temperature and pressure. This process:✔ Protects the catalyst in the reformer unit (since ...
🔹 Radiography in Oil & Gas (NDT) 🏭📸 Radiography is a non-destructive testing (NDT) method used in the oil & gas industry to inspect the internal structure of welds, pipelines, pressure vessels, and other components without damaging them. It uses X-rays ...
