Polygeneration energy system based on oxygen-blown coal gasification - page 7

Though the above-mentioned results are rather simplified and should
be adjusted according to the concrete situation, the potential benefits of
polygeneration system are no doubt obvious.
The Grand Western Development of China is a huge project in the
21st century. The target is to change the backwardness of west regions,
to develop the regional economy, to cultivate the new educated generation
and to improve the living standard of local people. However, the target
can be hardly realized by only exporting the natural resources in raw form.
Some new innovative approaches should be adopted to make the natural
resources be more value-added. To this point, the concept of polygeneration
could be a good enlightenment.
The Policy Support and Starting Steps for the Development of
Polygeneration System in China.
1. Because polygeneration is a large cross-sector system, its development
depends on the support and coordination of different industry sectors (such
as chemical and power generation sectors) and Central Government from
the standing point of whole nation’s benefits. Therefore, the boundary
between different sectors must be broken at first.
2. State Development and Planning Commission (SDPC), State Economic
and Trade Commission (SETC) and Ministry of Science and Technology
(MOST) must have a concordant action and multi-layer arrangement. For
instance, the fundamental study of this system should be conducted via
State Key Fundamental Research Program, the industrial demo of the
system should be supported by S-863 Program, etc. Besides, a favored
policy under the guidance of government should be issued, since every
new technology and system will have buy-down process. It is irrelevant to
claim unreasonable high request from the very beginning.
3. The utility must loose the regulation of grid connection. Therefore,
the owner of polygeneration system can sell the generated electricity to the
grid at reasonable price.
4. There are two starting options: firstly, in the coal abundant region
(especially coal with high sulfur content), to set up an industrial scale demo
with co-production of power, methanol and syngas using once-through
liquid-phase reactor. It could be expanded according to the availability of
investment, and will serve a impressive example for other regions and
particularly for the West Part of China. Secondly, in the vicinity of oil
refinery, to construct a polygeneration plant using the high sulfur content
residues as feedstock and hence to solve the problems caused by high sulfur
content crude oil.
5. Utilizing the achievement obtained by many research institutes and
enterprises in China, to organize a coordinated team for designing and
construction of polygeneration system with our own intellectual properties.
6. Clean utilization of coal and mitigation of CO
2
emission are the
global issues. Support and donations from international organizations, such
as UNDP, World Bank, Asia Development Bank, GEF, should be pursued.
