How To Remove H2S and CO2 from LNG?

This article will outline the process of how to remove hydrogen sulfide (h2s) and carbon dioxide (co2) from a natural gas stream. The point of this article is to make it easier for LNG operators to reduce the costs of gas treatment by removing waste gasses before they can affect plant production or equipment.

LNG is a very dangerous gas and must be handled with care. If mishandled, it can release large amounts of H2S and CO2.

To remove H2S and CO2 from LNG, you will need the following supplies:

1. A vacuum cleaner

2. Fermentation agents (such as kefir or yogurt)

5. A pot to cook the food in

6. A filter (such as a carbon filter)

7. A measuring cup

8. A countertop or table

9. LNG tanks or containers (if removing H2S) 

10. A hot plate

Remove the gas from H2S and CO2 by using a vacuum cleaner. Remove as much of the gas as possible without removing any food particles, as this will result in a "dirty" ferment that may not be edible. You can use the vacuum cleaner to remove all of the gas, but it's recommended that you use 1/4 to 1/8 cup of liquid carbon dioxide (CO2) remover per gallon of LNG (1 ml per 9 gallons). 

Then, add more LNG if necessary for a pail to remain full . Do not add more LNG than necessary as it may lead to a "dirty" ferment.Be careful of using an open flame so that the gas does not become ignited. A way to light these materials is with a butane lighter or lighter fluid. If your system uses a butane lighter, you can use the flint wheel to ignite the fuel, after opening the valve and before removing your container from within the chamber.
