2. HYSYS SIMULATION PROJECT100 MTPD HYDROGEN PEROXIDE (50%) PLANT

3. DEFINITION OF THE PLANT • A hydrogen peroxide plant is to be set-up at Gazaria, Munshiganj having a capacity of 100 metric ton of hydrogen per oxide (50 % w/w) per stream day, corresponding to 33,000 metric ton of hydrogen peroxide(50% w/w) per year, including all off sites, auxiliaries, utilities and supporting facilities using natural gas as feedstock and fuel.

4. SPECIFICATION OF RAW MATERIALS • NG from TITAS Gas • Methane > 96 % (V/V) • Calorific Value > 1000 Btu • Pressure > 240 kPa • Temperature about 5-15 oC • Air • Water

6. SPECIFICATION OF PRODUCT H2O2 specification: • H2O2 content 50% • Free acid (as H2SO4) 0.040% max. • Non-volatile matter 0.080% max. • Stability 97.0% min. • Freezing point -52.2°C • Boiling point 113.8°C • Density 1191 kg/m3

7. PROCESS SELECTION • By Auto-oxidation of alkylanthraquinones • By Electrolysis from Ammonium Bisulfate. • From Barium Peroxide • By oxidization of isopropanol Auto-oxidation of 2-ethylalkylanthraquinone is selected for this project.

8. DESIGN BASIS Geological Data • Location The site for the plant is selected on the bank of river Meghna at Baluakandi under Gazariaupzilla in Munshiganj district. • Load bearing capacity: The soil has a bearing capacity of 0.38 ton/ft2 required piling is used. • Corrosive tendency: Non Corrosive

9. DESIGN BASIS (Contd.) Climatic condition • Dry bulb temperature (maximum) 35 oC (summer) • Dry bulb temperature (maximum) 26 oC (winter) • Wet bulb temperature (maximum) 29 oC (summer) • Wet bulb temperature (maximum) 22 oC (winter)

10. DESIGN BASIS (Contd.) Meteorological condition • Average monthly Temperature 35oC (max.) • Average Temperature 30oC • Average annual rainfall 2850 mm • Wind flow Direction = South to North Velocity = 52 mile/h

11. DESIGN BASIS (Contd.) Utility • Electric Power • Voltage 380/220 V • Frequency 50 Hz • Phase 3 phases • Cooling Water Inlet Outlet Temperature < 30 oC 38 oC Pressure 0.5 MPa 0.2 MPa Turbidity ≤ 50 mg/l Chlorine < 5 ppm PH 6.5 – 8

12. PROCESS INVOLVED Four main stages involved: • Hydrogen Generation ( Reformer) • Hydrogenation • Oxidation • Extraction and Purification

13. REACTIONS INVOLVED • Reformer: • CH4+H2O = CO+3H2 - Q • CO + H2O = CO2+H2 + Q • Hydrogenation And Oxidation tower:
