Project Title: Just Scrub It! (Submarine’s air generators improvements)
Date: 2/12/15
Supercomputing Challenge Interim Report
Problem Definition:
The problem we are faced with is the fact that the CO2 scrubbers and O2 generators in submarines are too bulky, and they’re harder/slower to fix because of the size and complexity of the machines.
Problem Solving Plan:
We are going to create a model in Netlogo showing how the oxygen and carbon dioxide molecules are recycled and sorted into separate machines.
Progress Description:
At this point, our team is still in the research phase of the project. We’ve learned:
• The air we breathe on land consists of:
Nitrogen: 78 percent
Oxygen: 21 percent
Argon: 0.94 percent
Carbon dioxide: 0.04 percent
• The air in submarines consists of:
NO2: limit of 5 parts per million
CO2: limit of 5000 parts per million
CO: limit of 35 parts per million
SO2: limit 2 parts per million
Formaldehyde: limits 2 parts per million
Akrolein: limit 0.1 parts per million
NH3: limit 25 parts per million
O3: limit 0.1 parts per million
H2: limit 2 %
Cl2: limit 1 part per million
H2O2: limit 1 part per million
Two models that we are looking at using elements from are: GasLab Two Gas & Connected Chemistry 6: Volume and Pressure.
From the first model, GasLab Two Gas, we are going to make the two molecules attach to a surface, but only one molecule will adhere. We have to figure out how to get the CO2 molecules to attach to a surface.
From the second model, Connected Chemistry 6: Volume and Pressure, we are going to use the coding that indicates when the molecules ‘touch’ the boundaries to model the pressurized environment inside a submarine.

Purpose / Results:
The purpose of this is to improve submarine’s generators and scrubbers, making the air in the submarines closer to the air on land. Oxygen has to be replenished as it’s consumed, if the percentage of oxygen falls too low; a person will suffocate. If the carbon dioxide rises too high, it becomes toxic. It is important to find a way to make the device smaller because it will make it easier to fix and replace. It will also free up space in the submarine for more important equipment. The first course of action we will take is to identify the compounds in air and how they are processed through the submarine’s devices. Then we will find how efficient this process currently is so that we know how to make improvements in the scrubber/generator.
