Hydrogen Tank Design and Optimization Project

Specification: 

  1. Hydrogen Tanks volume is approximately 1 liter.
  2. Hydrogen is compressed to 8 bar.
  3. Normal operating condition (room temperature and humidity).
  4. Maximum budget is Rp500.000

Material Selection 

  SS-304 material by looking at the ASME II D table, a yield strength is 30,000 psi, based by calculations using ASME VIII, this material withstand a pressure of 32 bar, this tube is sufficient to withstand a pressure of 8 bar.

Design 

  Based on ASME VIII Div 1, we get
  Joint efficiency (E) = 0,85
  MAWS (SS-304 Seamless Pipe) = 30000 psi
  OD = 3,94 inch = 100.76 mm
  Outside radius (r) = 50.038 mm
  Corrossion Allowance (CA) = 0,01 inch = 0.254 mm
  Thickness (ta) = 0,05 inch = 1.27 mm
  Thickness (t) = (ta-CA) = 0,04 inch = 1.016 mm

  Find Diameter and Height
  In this case we know that Volume of Tanks is V = πr^2h, so we know that V = 1L or 0,001 m^3 and OD 10cm (0.1 m)
  0.001 m^3 = 3.14 x 0.05^2 x h
  h = 0.13 m = 13 cm, so height of the tanks is 13 cm

Manufacturing Process 

  Prepare the chosen materials in accordance with the design specifications.
  Manufacturing process may involve cutting, forming, and welding the steel plates.

Quality Assurance and Testing 

  Hydrogen storage systems are subject to specific regulations and standards, depending on jurisdiction and application. Ensure compliance with applicable codes, regulations and industry standards, such as those set by the American Society of Mechanical Engineers (ASME) or the International Organization for Standardization (ISO).

Total Cost 

  In the online shop we get price of SS - 304 size 100x400 with thickness 1.2 is Rp120.000, and add estimated cost in machining and labour Rp200.000. So total cost is approx Rp320.000

  import matplotlib.pyplot as plt
