180 New Trends in Coal Conversion

7.2.1.1.2 Shell Global Solutions International B.V.
In China, Shell gasification technology has been commercialized for more than
15 years, and until 2016, Shell has sold 22 license projects, with 23 gasifiers in oper-
ation, and 6 gasifiers to be started up (von Kossak et al., 2016).
The Shell Coal Gasification Process (SCGP) is based on a pressurized, entrained-
flow slagging gasifier, which is able to operate in a wide range of feedstock (coal,
lignite, petcoke, etc.) to produce syngas. Nowadays the same technology is used in
two different approaches, the SCGP syngas cooler lineup and the SCGP bottom
quench coal gasification technology. Further details are given in Shell Global
Solutions (2014) and van den Berg et al. (2014).
Some significant examples of the broad range of applications of Shell coal gasifi-
cation technology in China are summarized in the following section:
• As an example of the syngas generation for methanol, ammonia, and hydrogen pro-
duction, the Yueyang Sinopec and Shell Coal Gasification Co. Ltd. joined their
effort in 2006 to build and operate a facility with a capacity of 2000 tons of pulver-
ized coal per day to produce syngas for urea/fertilizer (van den Berg et al., 2014).
• Shell Hybrid Demonstration plant in Nanjing: In 2011, Shell teamed up with
WISON to jointly demonstrate the novel bottom quench technology. In 2013,
they successfully started a 1000-t/d SCGP bottom quench technology demonstra-
tion plant in the Nanjing industrial park (Smit et al., 2015).
• Shanxi Lu’an Coal Mine Group has constructed a coal-to-liquids (CTL) plant with
four SCGP gasifiers with a capacity of 3200-t/d dry coal intake capacity. This plant
has been built in the context of the Lu’an CTL project, which is the flagship project
of CTL of Shanxi, and also China’s national CTL demonstration project in the 12th
Five-Year Plan (van den Berg, 2015).

7.2.1.1.3 Siemens Fuel Gasification Technology GmbH & Co.
The development of the Siemens gasification process was begun in 1975 by Deutsches
Brennstoffinstitut Freiberg/Sa. (DBI, German Fuel Research Institute). It is based on a
dry-feed, pressurized entrained-flow gasifier which operates at HPs (40e46 bar) and

high temperatures (1300e1800 C). Developments of the Siemens Fuel Gasification
®
(SFG ) technology and interests can be found elsewhere (Morehead and Battke, 2014).
Currently, several of the most representative examples of commercial application of
®
the SFG technology are in China. They are as follows:
• GreenGen IGCC Project: Using local subbituminous coal, the GreenGen program
has the goal to develop a large-scale demonstration project in Tianjin, near Beijing,
China, that will include integration of key technologies such as IGCC, CCUS, fuel
cell power generation, and combined-cycle power generation based on hydrogen-
rich turbines and polygeneration. The plant is expected to be in operation in the
2020s (Global CCS Institute, 2017; Morehead, 2014; Shisen, 2014).
• Shenhua Ningxia Coal Group: In the Ningxia Coal-to-Propylene Project (NCPP,
Fig. 7.2), with four gasifiers in operation mode and one in standby mode, from a
dry-coal input of 200 TPD per gasifier, the methanol production is expected to
be around 5000 tons/day. Moreover, it seems that Shenhua Ningxia Coal Group
