Laboratory-Scale Gasifier

The Laboratory-Scale Gasifier (LSG) at Southern Research is effective equipment for both fundamental research and screening combustion-related technologies prior to pilot-scale or slipstream testing. Figure 1 contains a picture of the main reaction chamber of the facility, which is composed of a 1" thick pressure vessel machined out of a solid piece of Haynes HR-160 Incoloy, which is designed to operate safely at a pressure of 400 psi, while the temperature is as high as 2000°F.

The Laboratory-Scale Gasifier may be used to simulate fixed-bed, fluidized-bed, and entrained-flow gasification methods on the laboratory scale, with precisely controlled temperatures, pressures, fuel and gas feedrates, residence time, and additive introduction, accompanied with hot-syngas cleanup technology evaluation on the back end.

In addition to providing the capability to test fundamental gasification reactions and concepts, the LSG may be used to produce syngas for post-gasification research, such as hot-gas cleanup, syngas reforming, fuel cells, and gas turbine research.

Gasification byproducts, such as char and spent sorbent, are collected on the small candle-filter element inside the top chamber of the gasifier, while the gas leaving the reactor is analyzed by online monitors, including an MKS 2030 FTIR and a GC Mass Spectrometer. These monitors measure the concentration of hydrocarbons, nitrogen and sulfur compounds, CO and CO₂, water vapor, acid gases, light aliphatic and aromatic organic compounds and any tars that escape the reactor. The filter element temperature may be adjusted to accommodate the desired conditions.

Among other things, the LSG is used for evaluating biomass gasification for distributed energy purposes, investigating corrosion in syngas environments, and provide real syngas to challenge advanced hot-syngas cleanup technologies.
