◀️هر چیزی که بگندد، نمکش میزنند؛ وای به روزی که بگندد نمک▶️
این ضربالمثل فارسی، تنها یک جمله ادبی نیست؛ بلکه توصیفی از فلسفه اعتماد به آخرین لایه حفاظتی برای جلوگیری از فساد مواد غذایی است.
بر اساس LOPA وقتی فشار در یک تجهیز از محدوده ایمن فراتر میرود، ابتدا سیستم کنترل فرآیند تلاش میکند شرایط را به ح…

🔴When evaluating a fire pump performance curve, focus on these critical requirements:
✅ The rated duty point should be located in the stable operating region of the curve.
✅ Prefer a relatively flat and stable pressure-flow characteristic to accommodate varying fire demand conditions.
✅ Always evaluate the complete pump curve—not just the rated …

The Continuous Catalyst Regeneration (CCR) system plays a critical role in maintaining the long-term efficiency and stability of reforming units by continuously restoring the activity of the catalyst that is exposed to deactivation during the reaction process.
🎯 Objective of the Regeneration Loop: The main objectives of the regeneration section in a CCR unit includ…

Nitrogen is removed in catalytic hydrotreating by the breaking of the C-N bond producing a nitrogen free aliphatic and ammonia. The breakage of the C-N bond is much more difficult to achieve than the C-S bond in desulphurization. Consequently denitrification occurs to a much lesser extent than desulphurization.
Nitrogen is typically not a significant problem in virgin…

23 May 2024, 09:50 UTC≈5,900 views11 reactionsread 8 August 2026 Helical Strakes are aerodynamic stabilizers which are sometimes used to reduce the forces and deflections of the stack experienced due to vortex shedding. Strakes consist of three (3) vanes which can be wrapped in a helical pattern on the upper 1/3 of the stack. They have the appearance of a “Snake” which spirals around the stack.
If there is another stack (or tall structure) that is nearby, then the interference ef…

Showing the 12 most recent of 18 posts we hold for @Refinerytraining. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
