Slide 7: Outline
Outline: Background Background information relating to the vented gases containing hydrogen and previous reports. Facts about Hydrogen Information about hydrogen and what happens when it is released into the atmosphere as a gas. Facts about ‘Fuels’ What is LEL? Summary Page 1
Slide 8: Background
Background: Gases containing hydrogen (H2) are vented from the Ammonia Plant during start-up. The hydrogen containing gas is vented from two stacks, SP8 and SP9, for up to 6 hours but not from both stacks at the same time. Venting occurs from SP8 first followed by venting from SP9. Both stacks are e
Slide 9: Facts about Hydrogen
Facts about Hydrogen: Hydrogen gas (H2) is a very ‘light’ chemical. How ‘light’ is Hydrogen gas? Hydrogen gas is 2 times lighter than helium . Hydrogen gas is 14 times lighter than air. What does this mean? What happens when you fill a balloon with helium and let it go? It rises up into the sky. Wha
Slide 10: Facts about Hydrogen
Facts about Hydrogen: So what does this mean for hydrogen gas? What would happen if you filled a balloon with hydrogen gas? It would rise up into the sky. How does this apply to the stacks SP8 and SP9? What would happen to vented hydrogen gas? Keep in mind what happens to a hydrogen balloon. The rel
Slide 11: Facts about 'Fuels'
Facts about ‘Fuels’ : What does LEL mean? LEL = Lower Explosive Limit LFL = Lower Flammability Limit This is the lowest concentration of a gas in air that can be ignited in the presence of a flame. Below this concentration, the mixture is referred to as a ‘lean’ fuel mixture. What is the LEL for Hyd
Slide 12: Facts about 'Fuels'
Facts about ‘Fuels’ : What does all this mean? If hydrogen gas is mixed with air and the concentration of the hydrogen gas in the air is less than 4 vol %, then it will not ignite even if a flame or ignition source is present. What is the concentration of hydrogen in gas vented from SP8 or SP9? The
Slide 13: Summary
Summary: Hydrogen gas is very light and will want to rise into the sky. To ignite hydrogen gas the concentration must reach 4 vol % in air with an ignition source present. The ground level concentration of hydrogen gas vented from the stacks, SP8 and SP9, is significantly lower than 4 vol %, even un
