1 Carbon Dioxide Sequestration-A Green Approach
Team Leads: Ranjana Juneja Pre final year Chemical Engineering Sawan Patidar Faculty Advisor: Dr. S. Suresh Assistant Professor Chemical Engineering

2 FACULTY ADVISOR Name: Dr. S. Suresh
Designation: Assistant Professor of Chemical Engineering Dept. Qualification: Ph.D. (IIT Roorkee), M. E., B. Tech Specialization: Chemical Engineering, Environmental Engineering Area of Interest: Energy and Biochemical Engineering

3 PROBLEM The carbon dioxide concentration in the atmosphere is increasing at an alarming rate. The level has reached around 400 ppm as recent report by Dept. of Energy,2012 reveals. Leading to global warming and further consequences.

4 STATISTICS

5 Existing SOLUTION Mineral sequestration Geological sequestration
Ocean sequestration

6 MINERAL SEQUESTRATION
Reaction of CO2 with Mg and Ca containing minerals to form carbonates. Olivine (MgSiO4) and wollastonite (CaSiO3)

7 GEOLOGICAL SEQUESTRATION
CO2 is injected into underground formations. Types of formations: Depleted oil fields Unmineable coal fields.

8 OCEANIC SEQUESTRATION
Direct injection of CO2 in deep areas of ocean.

9 BIOLOGICAL SEQUESTRATION
Micro-algae is used to capture CO2. Biomass so produced can be further processed and used.

10 Liquid absorption technique
Different ionic materials(olivine concrete, lithium aluminate) are used. Optimization of result through Aspen Tech.

11 For Further Processing
A HYBRID SOLUTION Regulator Energy Absorption Column Sun Solar Panel Solvent CO2 CO2 Solvent Unabsorbed CO2 Biomass For Further Processing Micro Algae Cultivation Reactor Micro Algae cultivation reactor

12 Materials Required For solvent absorption technique:
Green materials/ ionic solvent Absorption Tower For Biological sequestration: Seeds for Algae growth Nutrients Reactor
