Summary Overview Experimental accomplishments Experimental Obstacles Base case and UNISIM design Final Design Questions
4
Overview Use algae to convert CO2 to lipids Convert lipids into biodiesel Scaled to industrial application
5
Preliminary Experiments Growth studies on local algae Conducted research on various strains Chlorella vulgaris
6
Pilot Plant Construction
7
Pilot Plant Algae was initially grown in growth chambers Transferred to reactor Bacteria was also introduced Bacteria outcompeted algae for nutrients Experimentation was discontinued
8
Base Case Developed a process flow diagram Utilized UNISIM process simulator to model Catalyst design decision Early equipment selection
9
Process Flow Diagram
10
UNISIM Developed biomass and triglyceride hypotheticals Useful for early estimates of equipment sizing Models liquid operations better than solid
11
Final Design Hand calculations to size equipment Develop a piping and instrumentation diagram Process costing Feasibility analysis
12
Obstacles Reasonable sizing estimates of photobioreactor Solids handling Dewatering Crushing
