6 H 2 O 2 specification:  H 2 O 2 content50%  Free acid (as H 2 SO 4 )0.040% max.  Non-volatile matter0.080% max.  Stability97.0% min.  Freezing point-52.2°C  Boiling point113.8°C  Density1191 kg/m 3 SPECIFICATION OF PRODUCT

7  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 Geological Data  Location The site for the plant is selected on the bank of river Meghna at Baluakandi under Gazaria upzilla in Munshiganj district.  Load bearing capacity: The soil has a bearing capacity of 0.38 ton/ft 2 required piling is used.  Corrosive tendency: Non Corrosive

9 Climatic condition  Dry bulb temperature (maximum) 35 o C (summer)  Dry bulb temperature (maximum) 26 o C (winter)  Wet bulb temperature (maximum) 29 o C (summer)  Wet bulb temperature (maximum) 22 o C (winter)

10 Meteorological condition  Average monthly Temperature 35 o C (max.)  Average Temperature30 o C  Average annual rainfall 2850 mm  Wind flow Direction = South to North Velocity = 52 mile/h

11 Utility  Electric Power ◦ Voltage380/220 V ◦ Frequency50 Hz ◦ Phase3 phases  Cooling Water Inlet Outlet Temperature< 30 o C38 o C Pressure0.5 MPa0.2 MPa Turbidity≤ 50 mg/l Chlorine< 5 ppm P H 6.5 – 8

12 Four main stages involved: 1. Hydrogen Generation ( Reformer) 2. Hydrogenation 3. Oxidation 4. Extraction and Purification

13 A. Reformer:  CH 4 +H 2 O = CO+3H 2 - Q  CO + H 2 O = CO 2 +H 2 + Q B. Hydrogenation And Oxidation tower:
