Description of Challenge
Rice straw is burnt each year in Egypt in massive amounts. This disrupts the ecosystem and causes pollution and health problems. Recycling of waste straw to produce gas solves a variety of problems and produces local renewable energy.Gas production from rice straw
Solution
Stages of the production of gas:
Include gas conversion unit the following stages:
1 – pressed straw storage (15 thousand tons)
2 – Unit chop straw
3 – Unit straw burning up to 1200 ° C
4 – Control unit in the resulting gases
5 – filter Wet Scrubber
6 – gas tank:
Nitrogen gas 41%
Carbon monoxide 27%
Methane 13%
Hydro carbonate 4%
Other gases 15%
Mode of Operation:
1. Collection after burning gases and Filter
2. Experience by gas flame color
3. Allow the passage of gas to the tank
4. Works in a storage tank of gas above the surface of the water
– Rising cover by the volume of the gas reservoir
– You select the measurement tank is full (350 m3 gas)
5. Gas network for Home Delivery, where the Natural Gas Company set up a network to feed 300 homes
