Shell (China) Limited and Shenhua Coal to Liquid and Chemical Co. Ltd. (Shenhua) have agreed to seek opportunities for conducting joint research and development in advanced coal technology.
Additionally, Shell Global Solutions International B.V. (Shell) also qualified three Chinese companies for the manufacture of key equipment for the Shell Coal Gasification Process (SCGP), in order to make the Shell technology more competitive in the Chinese market.
Shell and Shenhua. Under a memorandum of understanding (MoU) between Shell and Shenhua, the two parties will explore opportunities to jointly develop more advanced coal gasification technology. In addition, they will discuss the possible application of carbon capture and storage (CCS) technology. A joint working team will be set up to implement the agreement.
Shenhua has built the world’s first million-tonne level direct coal liquefaction project in China’s Inner Mongolia, equipped with two gasifiers using Shell’s coal gasification technology to produce hydrogen from coal.
The Shell-Shenhua MoU was signed alongside government meetings between China and the Netherlands on sustainable energy cooperation. Officials from the National Energy Administration of China and the Ministry of Economic Affairs of the Netherlands witnessed the signing, after their meeting concluded with a memorandum of understanding on cooperation in the field of energy between the two government departments.
Shenhua Coal to Liquid and Chemical Co. Ltd. is a subsidiary company to Shenhua Group Corporation Limited. Shenhua Group is the world’s largest coal company. It not only builds coal-to-liquid and coal-chemical projects, but also develops CCS, hydrogen power and renewable energy technology.
Shell has been developing and commercializing coal gasification technology since the 1970s with a total of 26 licensing agreements signed worldwide. Shell has signed 19 licensing agreements with different Chinese users. Eleven plants using Shell coal gasification technology, including Shell’s joint venture with Sinopec in Yueyang of Hunan Province, have been started up.
Gasification equipment. The SCGP is a dry-feed, oxygen-blown, entrained flow coal gasification process which has the capability to convert virtually any coal or petroleum coke into a clean medium Btu synthesis gas.
In SCGP, high pressure nitrogen or recycled syngas in used to pneumatically convey dried, pulverized coal to the gasifier. The coal enters the gasifier through diametrically opposed burners where it reacts with oxygen at around 1,600 °C. The gasification temperature is maintained to ensure that the mineral matter in the coal is molten and will flow smoothly down the gasifier wall and out the slag tap. The hot syngas exiting the gasifier is quenched to below the softening point of the slag and then cooled further in the syngas cooler.
Research on the SCGP began in 1972.
Dongfang Boiler Group Co., Ltd., Suzhou Hailu Heavy Industry Co., Ltd., and Wuxi Huaguang Boiler Co., Ltd. signed qualification contracts with Shell which allow them to manufacture internal components of coal gasifiers and syngas coolers. This equipment is key to Shell’s coal gasification technology and Shell will work with the qualified manufacturers to ensure their product quality.
The qualification contracts were signed alongside the government meetings on sustainable energy cooperation.
