Overview of coal gasification usage in China (coal feed rate, pressure, etc.): Shell signs new gasification technology transfer contract – 20th such project in China
Thread Content
Let’s share information on the companies using various gasification units in China at present, as well as the amount of coal fed into these units. The format should be as follows:Ash fusion polymerization: Shaanxi Chenggu Fertilizer Factory – gasification pressure of 0.03–0.05 MPa, coal feed rate of 100 t/d; started operation in 2001.
Shell: Datang International Power Generation – gasification pressure of 4.0 MPa, coal feed rate of 2800 t/d; expected to start operation in 2010.
Two-stage furnace: Inner Mongolia Shilin Chemical Co., Ltd. – gasification pressure of 4.0 MPa, coal feed rate of 1000 t/d; expected to start operation in 2010.
GE coal slurry: Shandong Lunan Fertilizer Factory – gasification pressure of 2.70 MPa, coal feed rate of 720 t/d; started operation in 1993.
Opposed multi-nozzle type: Yuncheng Guotai Chemical Co., Ltd. – gasification pressure of 4.0 MPa, coal feed rate of 1150 t/d; started operation in 2005.
Shandong Hualu Hengsheng – gasification pressure of 6.5 MPa, coal feed rate of 750 t/d; started operation in 2004.
GSP: Shenhua Ningxia Co., Ltd. – gasification pressure of 4.0 MPa, coal feed rate of 2000 t/year; expected to start operation in 2010.
Shell has signed a new contract with Hebi Coal and Electricity Co., Ltd. for the transfer of gasification technology; coal feed rate is 2700 tons per day, for methanol production.
Let’s work together to provide more information on technologies such as Texaco, opposed multi-nozzle type, Shell, GSP, multi-component slurry, two-stage furnaces, aerospace furnaces, Endress furnaces, and Lurgi furnaces. :handshake Last edited by purpleghj on 2007-12-15 12:36 ]

Guizhou Tianfu Group: coal input of 2000 t/d; expected to start operation by the end of 2009
I wonder if the original poster knows anything about the investment status of these companies??:handshake :handshake
I only know about ’Tang Dynasty’ s investment details: Great Tang invested around 3.5 billion yuan in 3 gasification units, including costs related to coal preparation and gasification. Since lignite is used, the investment in coal preparation might be higher than that of other Shell companies. This post was last edited by purpleghj on 2007-12-14 09:17
So much money is being invested just for 3 shell gasification units – Datang really is wealthy.
There wasn’t a very good solution either for lignite; at that time, advanced technology was the priority, which is why Shell was chosen. Actually, Lurgi could have been considered as well, but that would have required installing a large number of boilers. :lol
4,000 tons for the Tang Dynasty? Damn, Shell is doing amplification experiments, right?
Shell’s greatest success lies in gas power generation. Moreover, the so-called fully boilerless process presents many problems; many such systems have been introduced in China, but it seems none of them have been able to operate continuously without issues. There have been quite a few difficulties involved. Well, China is a testing ground for coal chemical technology. TEXCO took nearly 10 years to get its system up and running after introduction, and I think Shell experienced something similar as well
Dagang did indeed inject 4,000 tons of coal, but since the lignite used had a moisture content of up to 30%, the equivalent amount of pulverized coal was 2,800 tons.
Shaanxi Weihe Fertilizer Plant: gasification pressure of 6.5 MPa, coal feed rate of 1,500 t/d; came online in 1996
Multi-component slurry: Inner Mongolia Sanwei Resources Group Company, gasification pressure of 4.0 MPa; expected to come online in 2008
For that 3D project, coal is extremely cheap; the price at the mine entrance is said to be less than 50 yuan. However, at present, the supply of coal for chemical industries in Ordos is a major problem – it’s not clear how they plan to address it. What is the scale of their project at present? The initial amount designated was probably 200,000 tons of methanol. It seems that domestic technology is quite effective in small and medium-sized enterprises; let’s wait and see!
The three-dimensional scale remains at 200,000 tons, and the 900,000-ton methanol project of Jutai in the Dali Park has also begun construction
The waste boiler process of Shell’s gasification furnace is suitable for power generation; however, for ammonia synthesis and methanol production, it is necessary to add steam to the syngas, which makes it less advantageous compared to the quenching process. Shell needs to develop a quenching-based process to meet the needs of China. I heard that Sinopec loses 800 million yuan per year in this area. Do not treat us as a testing site for gasifiers abroad; what is needed in production are mature technologies to avoid as many detours as possible. It took three years for TEXCO to reach full production capacity after introducing the technology. Furthermore, the coal type required for gasification in the pulverized coal water-cooled wall has stricter requirements than those for TEXCO. Therefore, we must not be reckless when choosing a process; we need to conduct a thorough evaluation to avoid irreparable losses.
Water for coal chemical projects in Inner Mongolia must be obtained through water rights exchange
According to the latest surveys, the estimated commissioning dates for these facilities are as follows: Hubei Shuanghuan Technology Co., Ltd., with a coal input of 900 t/d, scheduled to start operations in May 2006; Sinopec Yueyang/Shell Gasification Co., Ltd., with a coal input of 2000 t/d, scheduled to start operations in December 2006; Sinopec Hubei Fertilizer Plant, also with a coal input of 2000 t/d, scheduled to start operations in December 2006; Sinopec Anqing, with a coal input of 2000 t/d, scheduled to start operations in November 2006; Liuzhou Chemical Industry Co., Ltd., with a coal input of 1300 t/d, scheduled to start operations in January 2007; Yunnan Tianan Chemical Co., Ltd., with a coal input of 2700 t/d, expected to start operations in March 2008; Yunnan Zhenyi Fertilizer Plant, also with a coal input of 2700 t/d, expected to start operations in March 2008; Dalian Dahuahua, with a coal input of 1100 t/d, expected to start operations in June 2008; Yongcheng Coal and Electricity Group, with a coal input of 2000 t/d, expected to start operations in March 2008; China Shenhua Coal Liquefaction Company, with a coal input of 2x2000 t/d, expected to start operations at the beginning of 2008; Henan Zhongyuan Dahuahua Group, with a coal input of 2000 t/d, expected to start operations in March 2008; Henan Yima Kaixiang Group, with a coal input of 1000 t/d, expected to start operations in March 2008; Bohai Chemical Group Tianjin Alkali Plant, with a coal input of 2x2000 t/d, expected to start operations in 2010; Guizhou Tianfu Group, with a coal input of 2000 t/d, expected to start operations by the end of 2009
The information on floor 17 is fairly comprehensive; the following additions are provided: 1. On December 4, 2007, the air separation unit with a capacity of 53,000 Nm3/h for Yongcheng Coal and Electricity Group’s Longyu Coal Chemicals’ project to produce 500,000 tons of methanol per year was successfully commissioned. Based on the current situation, the coal gasification unit will not be put into operation until at least March 2008. 2. On December 1, 2007, the 52,000 Nm3/h air separation unit of Zhongyuan Dahua’s project with an annual methanol production capacity of 500,000 tons was successfully commissioned. Based on the current situation, the commissioning of the coal gasification unit is likely to occur around the same time as that of Yongcheng Coal and Electricity. 3. Although Henan Kaixiang Chemical’s production capacity is relatively low (200,000 tons of methanol per year), the start date of operations is uncertain due to funding issues; it would be good if it could begin operating in the first half of 2008. 4. The progress of Yunwei Shares’ Zhanhua company is worth looking forward to; at present, aside from the gasification stage, the subsequent purification and ammonia synthesis processes have been completed, which will certainly **reduce the startup time for the subsequent units.

The treatment of lignite is relatively complex, and the investment in coal preparation for the Datang project far exceeds that of other Shell gasification projects
Ash pyrolysis gasification furnace: Jinmei Group, 2.5 MPa, coal feeding rate of 1,000 tons per day; put into operation in 2009. Shijiazhuang Jinsihua Fertilizer Factory, 0.6 MPa, put into operation in 2008
Fengxi’s attempt to operate at 1.0 MPa was not successful; it’s quite unbelievable that Jinmei dared to use a furnace operating at 2.5 MPa. Which company is on the 20th floor?
