Engineering Selection Notes:
1. Flare: Inlet pressure of FAII (intermittent emergency) and FAIII (continuous enclosed) is designed at 25/30 mbar; FAIV includes a VFD booster blower for 90 mbar (10–20 kPa).
2. Biogas Holder (DMG): Table row shows 1-hour baseline; recommended storage time is 2 hours or more (e.g., 500 m³/h × 2h = 1,000 m³ effective volume -> select DMG-1150).
3. Biological Scrubber (BDS): Table models are calculated with inlet H2S = 2,500 ppm and outlet H2S = 200 ppm. For higher H2S or stricter outlet, packing volume scales proportionally or uses BDS-Custom-Made.

EnvironTec E-Care™ Smart Cloud Guard (benchmarking Fortune 500 smart service models) upgrades traditional 'firefighting repairs' into AI-driven predictive maintenance. Embedding 1,000+ biogas HAZOP safety and biochemical mechanistic rules, it generates 'Red, Orange, Yellow, Green' 4-color health diagnostic reports via continuous 14-day rolling telemetry: achieving 5-second abnormal SMS alerts directly to operators, locking biological scrubber temperature in the optimal 32–36°C microbial activity zone, intercepting double membrane gas holder overpressure tearing risks, and coordinating with ERP automated safety stock management for 24/48-hour express spare parts delivery—cutting plant energy and O&M costs by 20%–30% (ROI >300%). Through refined management, it foresees and prevents safety hazards, eliminating them before they can occur.
Circulation Temp: 34.6°C (Locked in 32–36°C SOB zone) | Outlet H2S: 18 ppm | AI-PID Micro-O2: Active
Target Dosing: 17.8 L/day (3.6 cm/day tank drop) | ERP safety stock auto-dispatches consumables within 24/48h.
Detected 66.5% time >38°C & 90.6% pure O2 overdose. Chiller valve & AI-PID micro-O2 corrected, saving $12k/yr.
Intercepted abnormal blower VFD fixed-frequency overpressure (>4.2 kPa). SMS pushed in 3.2s; emergency flare interlocked.
