Seeking help with chemical engineering design — Ammonia-nitrogen wastewater treatment project with a daily processing capacity of 300 m3

Thread Content

1. Design topic: Treatment project for ammonia-nitrogen wastewater with a daily treatment capacity of 300 m3. 2. Original data and technical requirements: Treatment capacity: 300 m3 per day; the treated water must meet **discharge standards. Main raw materials: wastewater (pH: 9–10, ammonia concentration: 12,000 mg/L, sulfate concentration: 3,000 mg/L, *ao acid concentration: 7,000 mg/L, chloride ions: 4,000 mg/L). Technical approach: Neutralization using sodium hydroxide, followed by separation via stripping distillation. Design phase: Detailed construction drawings. Design contents: 1) Review of literature and determination of the process flow based on the design requirements; 2) Material balance calculations; 3) Heat balance calculations; 4) Calculation and selection of equipment, including stripping towers, vapor-liquid separators, heat exchangers, storage tanks, pumps, etc.; 5) Economic feasibility analysis; 6) Drawings: a) Process flow diagram with control points (PID); b) Equipment layout diagram; c) Partial pipe layout diagram; 7) Design specifications
