Dibujar un diagrama que explica cómo gas natural es extraído y procesado para ser utilizado.

6

Explicar cómo se puede utilizar gas natural para:

6a

Producir hidrógeno

6b

Generar energía

6c

Transporte

CNG (Compressed Natural Gas) is used to provide power for internal combustible engines. It provides a much cleaner substitute than convention gasoline or diesel fuel. Liquified Natural Gas (LNG) use for commercial trucks and buses is rapidly expanding around the world.

6d

Una fuente de energía

It is used for waste treatment and incineration, glass melting, and food processing. It serves residential, commercial and industrial uses. It also serves as an ingredient for products like paint, detergents, carpets, as well as tires.

¿Gas natural se utiliza para hacer cuáles productos? Explicar el proceso en por lo menos dos de las respuestas.

Fertilizer

Of the many components found in nitrogen fertilizer, ammonia is one that can be produced from cheap raw materials. A combination of natural gas and steam is forced into a large container. The oxygen is then removed from the system by burning natural gas and steam. This process leaves primarily nitrogen, hydrogen, and carbon dioxide. The carbon dioxide is then removed from the system using electrical current.

Plastic

Natural gas can be used to manufacturer plastic materials. For this to be done, the natural gas must be converted to ethane. Heat generated from the conversion process poses a problem and must be removed. Methods have been developed that can heat and cool simultaneously, making the production of plastics from natural gas a viable and more cost effective alternative.

¿Cómo se produce etanol?

Ethanol is produced from any plant or crop source that contains a hefty amount of sugar. It can also be made from starch or cellulose; sources that can be converted to sugar.

Four Step Process

1. Crops or plants, used as raw materials are ground up.
2. The ground up material results in sugar, which is then dissolved.
3. Ethanol and carbon dioxide are produced as a byproduct by introducing bacteria that feed on the sugar.
4. The right concentration is obtained by removing the impurities in the ethanol.

9

Discutir en un grupo algunos de los efectos al entorno con respecto al uso de combustibles alternativos.

	Tip for earning from home during the pandemic
	Group discussion can be done with video conferencing.

This is an open group discussion with a unit counselor and/or the instructor teaching the honor.
