One dimensional model of absorption of CO2 in falling film

Abstract

This paper describes a model of the absorption process in a falling film POE oil/CO2 absorber.  Absorption of CO2 into a laminar falling film on the surface of a vertical plate is considered. Necessary boundary conditions and simultaneous mass and heat transfer model equation are solved. The coolant side is assumed water at specified inlet and outlet temperature.  To solve this, finite element software has been used. The concentration, temperature and velocity profiles are obtained. The mass and heat fluxes along plate length are also depicted.

Low cost 100% Plant Oil Stove

A 100% plant oil (non-edible oil) stove to replace Kerosene as a cooking fuel. The fuel to be pursued is ’straight vegetable oil’ instead of bio-diesel because the ’straight’ vegetable oil will not undergo any processing or refining. 

The ultimate mission of the endeavor is to promote rural energy independence by encouraging the use of a renewable energy source (plant oil) instead of non-renewable sources like kerosene. If successful, this product will be a boon to several BOP (Bottom of Pyramid) people by reducing their dependence on Kerosene and encouraging the use of a more sustainable, renewable energy source.

Previous models can only burn for 2 hours before clogging up with carbon deposits. The goal is to adapt/modify/improve this stove design so that it can burn for 10 hours or more before requiring cleaning.

New toilet turns human waste into electricity and fertilizer

 Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing by up to 90 per cent compared to current toilet systems in Singapore.
