What is Gasificat
si-F--
Gasification may be defined as follows:
• "A process technology that is designed and operated
producing synthesis gas through the chemical converse
materials."
7acji4
carbonaceous
•
10 114
• "A process that converts carbonaceous mater6ts through a process involving
•
partial oxidation of the feedstock in a reducing atmosphere irrtife presence of
steam at temperatures sufficient to convert the feedstock to synthesis gas, to
convert inorganic matter in the feedstock to a glassy solid material known as,,
vitreous frit or slag, and to convert halogens into the corresponding acid
halides."
• "A process that incorporates a modern, high-temperature pressurized gasifier
with auxiliary gas and water treatment systems to produce refined product
synthesis gas, which when combusted, produces emissions in full compliance
with the Clean Air Act."

History of Gasification
• Coal Gasification used to produce medium quality gas since
middle 1800s. Coat heated in low oxygen environment to
produce synthesis gas, that was burned for heating and
lighting in the 1800s, and burned for electricity in the 1900s.
• Gasification used for the past 50 years in the production of
fuels and chemicals.
• Waste Gasification used in treatment of hazardous wastes,
and in conversion of MSW to Medium Calorific Value (MCV)
fuel.
EFTA_R1_01521308
EFTA02444459
Primary Advantages of Gasification
• Ability to produce consistent, high-quality Synthesis Gas
(Syngas) that can be used for energy production;
• Ability to accommodate a wide variety of gaseous, liquid,
and solid feedstocks;
• Major components of Syngas are C412, and CO2, with low
levels of N2 and CH4. SO, a d N0.14F substantially lower in

2. Combustion versus Gasification
Incineration
Designed to maximize the conversion
of feedstock to CO2 and H2O
Large quantities of excess air
Highly oxidizing environment
Operated at temperatures below the
ash melting point. Mineral matter
converted to bottom ash and fly ash.
Gasification
Designed to maximize the conversion
of feedstock to CO and H2
Limited quantities of oxygen
Highly reducing environment
Operated at temperatures above the
ash melting point. Mineral matter
converted to glassy slag and fine
particulate matter (char).

reclamation.

Gasification System Design
1. Gasification System operate by feeding carbon-containing waste
materials into a heated chamber, with a limited and controlled
amount of oxygen. This creates reducing conditions in the
Gasification Reactor.
2. At high operating temperatures in the Gasification Reactor,
chemical bonds are broken by oxidation and steam reforming at
temperatures sufficiently high to promote rapid reactions.
Gasification Reactor temperatures in range of 1,550 to 3,500 °F.
Primary components of Syngas created in Gasification Reactor are
CO and H2, with lesser amounts of H2O, CO2, N2, C114, H2S, and HCl.
Waste materials are converted from solids to gases, they are not
burned. Therefore, Flue Gas is much cleaner for Gasification
Process.
Slag has the consistency of glass, and Sulfur may be recovered in
elemental form, which may be sold.

Key Elements to a Successful Gasification
Facility
• Sorting Line required to remove high ash content materials such as metals,
glass, concrete, brick, rock, and soil;
• C&D materials should be diverted. Plastics and wood can be separated
from CEtD and transported to Gasifier;
• Shredder and pelletizer required to produce good quality, more uniform
pellets, and to reduce moisture content of waste to about 20%;
• Two stage Gasification required, (1) Conventional Gasification to convert
solids to syngas; and (2) Ash slagging unit required to convert carbon in
ash to syngas, increase BTUs of syngas, and convert ash to slag;
• Cyclone required after Gasifier to remove particulate matter from syngas
prior to combustion in Boiler;
• Boiler with Steam Turbine more efficient than Gas Turbine; and
• Air Quality Treatment system typically consists of Acid Gas Removal Unit,
Electrostatic Precipitator, Bag House with Carbon Injection, and Stack.
