Reformed (Catalytic) Gas: A "tailored" gaseous
fuel of high Btu content produced by fluidized or catalytic bed
treatment of hydrocarbon gases at a refinery. The composition
of reformed gas varies, but usually consists of Hydrogen (11
- 22%), Nitrogen (7 - 11%), Methane (30 - 40%), Ethane (13 -
16%), Ethylene (13 - 16%), Propane (0.5 - 2%), Propylene (2.5
- 12%), lower amounts (0.1 - 2%) of other light C4 - C6 alkanes/A
alkenes/dienes (i.e. cis/trans butadienes), Carbon Dioxide and
Carbon Monoxide. Such gases can be mixed with processed natural
gas to increase Btu content. |
|
Refinery Gas: Gases generated as by-products during the refining
of crude petroleum. The composition of these gases varies with
the crude source and can contain a significant Hydrogen and/or
sulfur content (i.e. Hydrogen Sulfide), light A
alkanes/alkenes such as Methane, Ethane, Ethylene, Propanes,
Propylene, Butanes, Butylenes, Dibutylenes, Pentanes, Pentenes,
Hexanes, low levels of Nitrogen, Carbon Dioxide, Carbon Monoxide
and trace Oxygen. |
|
Coke Oven (Coal) Gas: A gas mixture produced during coal carbonization
(inert gases are L.T. 50%). The typical composition is: Hydrogen
(45 – 54%), Methane (28 - 34%), Carbon Monoxide (6 – 7%). |
|
Producer Gas: A low Btu gas mixture produced by the incomplete
combustion of coal or coke in an air or air/steam based gas producer
unit (inert gases are G.T. 50%). The typical composition is Hydrogen
(5 - 10%), Carbon Monoxide (20 - 35%), Nitrogen (55 - 65%). It
is primarily used by the industry producing it. |
|
Water Gas (Blue gas): A low Btu gas mixture produced from a
reaction of steam with coke (inert gases L.T. 50%). The typical
composition is: Hydrogen (45 - 50%), Carbon Monoxide (40 - 50%),
Carbon Dioxide (3 - 7%), Nitrogen (4 - 5%). |
|
Oil Gas: A high Btu gas mixture (natural gas substitute) produced
from the thermal cracking of liquid hydrocarbon fuels. |
|
Blast Furnace Gas: A low Btu gas mixture produced from the
reduction of iron-ore in a blast furnace. |
|
Acetylene: (Commonly manufactured by reaction of calcium carbide
with water). Acetylene is a reactive gas that is typically dissolved
in acetone for safety purposes. Approximately 85% of all acetylene
produced is used for chemical synthesis. Fuel applications include
oxy-acetylene cutting/welding, heat treating and spectrometric
instrumentation (AAS). Trace impurities common to acetylene include:
phosphine, arsine, ammonia, hydrogen sulfide, acetone vapor and
air. |
