184 New Trends in Coal Conversion

• Luoyang, Henan Province: This project is sponsored by the China Yituo Group Co.
Ltd. of Luoyang, Henan Province. This facility is designed with 1 þ 1 BGL gasifiers
(one on line and one on standby), each 13 feet inner diameter, which operate at pres-
sures of up to 30 bar and a feed rate of 650 tons per day of local hard coal, to generate a
3
gas production of 43,000 Nm /h. The fuel gas produced is expected to be used in an
industrial complex as a substitute for 18 existing fixed-bed low-pressure gasifiers.

• Ordos Tuke, Inner Mongolia: This project is supported by China National Coal
Development Co. Ltd. and China National Coal Corporation. The facility has seven
BGL gasifiers (five on line and two on standby) of 13 feet inner diameter, which
3
operate at 40 bar to produce 295,000 Nm /h of synthesis gas from 1250 tons per
day of bituminous coal. The synthesis gas is expected to be used for the production
of 1 Mtons per year ammonia and 1.75 Mtons per year urea. The projected startup
date was planned for 2013/2014.
7.2.1.1.9 KBR-Southern Company
KBR’s proprietary Transport Integrated Gasification (TRIG TM ) technology was
designed to process low-rank, high-moisture, and high-ash coal. KBR and Southern
Company are working together to implement TRIG TM in a multitude of product appli-
cations to meet global demand for energy and chemicals.
KRB TRIG TM technology (advanced, pressurized, circulating fluidized bed [CFB]
gasification) is used by Berun Holding Group’s 100 kt/y ethylene glycol project in
Inner Mongolia with high-ash lignite as feedstock. The plant has a design capacity
3
of 35,000 m /h of syngas.

Dongguan Tian Ming Electric Power Company plant in Guangdong Province. TRIG
technology has been added to an existing gas turbine combined cycle plant, enabling it to
use SNG produced from 1600 tons/day of low-grade coals to replace the use of fuel oil.
7.2.1.2 Japan

In Japan, coal consumption has rapidly increased since the end of the 1990s, and the
Japanese government is actively promoting research and development (R&D) on CCT
to increase energy efficiency and carbon capture capability and simultaneously
decrease pollutant emissions.
IGCC power generation system is becoming a key technology to that aim (Guan,
2017). The most relevant examples will be discussed in the following section.

7.2.1.2.1 Osaki CoolGen Project
Two relevant IGCC technologies were developed in Japan during the 1990s. The first
one was the “Hydrogen-from-coal process” (HYCOL process) in 1991, a gasification
technology with an entrained bed, in which pulverized coal is gasified with oxygen

under high temperature (1500e1800 C) and HP (3 MPa) (Guan, 2017; NEDO,
2007). The second one was the “multipurpose coal gasification technology develop-
ment”, also called EAGLE Project. The EAGLE Project started in 1995, and its
