Features of GSP gasification technology: \"two highs and two lows\", namely high adaptability to various coal types and high technical performance indicators; Low investment, low maintenance costs. High adaptability to different coal types: it can be used from lignite to anthracite and even petroleum coke. Coal powder feeding is not affected by slurry-forming properties. There are no special requirements regarding ash content and ash fusion point ; High technical specifications: high gasification temperature, generally ranging from 1350°C to 1750°C. The carbon conversion rate can reach up to 99%; the methane content in the gas is very low (CH4 < 0.1% (V)), with no heavy hydrocarbons present. The concentration of useful gases in the syngas, namely CO + H2, is high, and the efficiency of cold gas utilization exceeds 80%* ; Low investment: For projects of different scales, gasification equipment of various specifications is developed; these specifications are smaller in size compared to similar technologies, resulting in lower costs for the equipment itself, construction, and transportation ; Low maintenance costs: Compact process flow ; The equipment has a long service life; it features a gasification furnace with a water-cooled wall structure, without refractory bricks, and is expected to last for more than 25 years ; By using a combined nozzle (which combines the ignition nozzle and the production nozzle), the expected service life of the main unit is over 10 years. Starting and stopping the operation is straightforward, and the time required is short (it takes only 1–2 hours to reach full capacity from a cold state). Typical gas composition in the outlet area of the GSP gasification unit (on a dry basis): Gas volume (%): H2 23.6%, CO 6.9%, CO2 3.1%, N2 4.0%, Ar 0.1%, CH4 0.3%, H2S 10.0%; Total 100.0%
It must be a type of fluidized bed; it’s indeed an excellent technology, with very low levels of CO2 and H2S. It’s suitable for purification using low-temperature methanol washing, but hydrogen needs to be added in order to produce methanol!
"\"Both CO2 and H2S levels are very low.\" This depends on the type of coal used. Its technological advantages lie in combining the features of Shell and GE, but it seems to lack practical engineering experience
Is the coal tar content high? What is the level of organic sulfur?
Based on the literature, it does seem promising, but the changes in decisions by Linggu and Huaihua are worth considering.
