Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to location and construction
of a plurality of the innovative layout and configurations of
plants consisted of several industries such as oil refining plant,
oil-fired or coal-fired power plant, cement and steelmaking
plants.
[0003] 2. Description of the Related Art
[0004] In 1950' in Japan, oil refining plants or petrochemical
complexes are constructed so as to be adjacent to each other and
alongside the sea. However, such complexes are only in
consideration of delivery and receipt of raw materials for
products, therefore, there are no significant consideration for
these plants within complex and for utilization of energy such as
power and fuel and/or waste materials between them.
[0005] Although there are cases that iron plants, steelmaking
plants, and power plants are constructed so as to be adjacent to a
petrochemical complex, each plant is independently arranged.
Therefore, efficiency of energy utilization for heat and power is
not so high on the whole. Moreover, waste materials are mostly
transported to other places for disposal, and effective utilization
of waste materials is not considered.
[0006] The patent on a combination of different kinds of plants is
disclosed in Japanese Patent No. 2576006 as "Power generating
method." A plant presented in this patent aimed to improve heat
efficiency at power generation, and result in energy saving and
prevention of global warming, in the plant which atmospheric
distillation unit is co-mounted with a steam power generator and a
gas turbine power generator using low sulfur crude oil.
[0007] Other patent is proposed of a system which is disclosed in
Japanese Patent Publication (Unexamined) No. Heisei 9-87640 as "A
residual oil treatment plant". In this patent, the plant is to
generate power efficiently and effectively utilizing heat energy
contained in residues and exhaust from a diesel engine.
[0008] On the other hand, a method, which is disclosed in Japanese
Patent Publication (Unexamined) No. Show a 63-260982 as "A method
of deoxidizing and supplying harmless pyrolytic gas from
combustible organic waste materials" is also proposed to pyrolize
and gasify combustible organic waste materials generated in an
industrial park and to return this low-pressure gas containing
hydrocarbon to factories and plants as fuel in the industrial
park.
[0009] Further, in U.S. Pat. No. 5,630,862, a refinery and an
iron-making process are combined to dispose of an environmentally
undesirable material and to provide a novel fuel for an iron-making
process.
[0010] Although the above-mentioned technologies have been proposed
mainly to save energy, prevent global warming and generation of
harmful materials through combination of plants and equipment,
there has been no industrial complex in which large-scale plants
for basic industrial products are combined so as to be adjacent to
each other to completely and effectively utilize energy, byproducts
as well as waste materials among them and to minimize the
generation of harmful waste materials which are disposed of and
treated outside.

40 and the like.
[0060] The oil refining plant R is, as illustrated in FIG. 2, a
plant that uses crude oil Rr as a raw material, and produces
gasoline Pr1, kerosene Pr2, gas oil Pr3, and residues Pr4, which
are obtained after hydrodesulfurizing fractions other than residues
in one lot through atmospheric distillation. In addition to the
above, LP gas not shown may be obtained. From storage tanks for
each product, sludge Wr1 is generated as a waste product, and from
a hydrodesulfurization unit not shown in the oil refining plant R
is generated spent catalyst waste Wr2, acid gas Wr3 as a gaseous
waste and waste liquid Wr4 at the same time. Further, in the
atmospheric distillation process and the like, exhaust gas Gr is
generated. In this connection, the waste materials Wr1 to Wr4 and
the exhaust gas Gr have conventionally been treated independently
outside of the plant in some cases. Products containing all the
residues and a part of the residual oil may generally be called
heavy oil, however, residues in the explanation described below
includes the heavy oil defined above.
[0061] The oil-fired power plant P, as illustrated in FIG. 3,
generates power Pp by rotating a turbine with steam generated from
the residues Fp or heavy oil, simultaneously generates exhaust gas
Gp through the combustion of the residues and the heavy oil Fp and
the like as well as the waste liquid Wp. Conventionally, both the
exhaust gas Gp and the waste liquid Wp have been treated in the
plant.
[0062] Further, the cement plant C is, as illustrated in FIG. 4, a
plant that mainly produces Portland cement by adding gypsum Rc2 and
the like to cement clinker which is obtained through burning of raw
materials such as limestone Rc1 and the like with heavy oil Fc as
fuel; at the same time, conventionally, it is required,
independently and outside of the plant, to exhaust gas Gc generated
from a kiln not shown and the like, and to exhaust liquid Wc from
other equipment in the plant.
[0063] Still further, the steelmaking plant S is, as illustrated in
FIG. 5, a plant that produces steel products from scrap Rs as the
main raw material while consuming power Es and heavy oil Fs as fuel
in an electric arc furnace, and in the same manner as the

lines, and when electrical power is transported, the transporter 3
comprises electric wires, and when other byproducts, waste
materials and the like are transported the transporter 3 comprises
belt conveyors, trucks, wagons and the like; a suitable means of
transport is selected in accordance with the object

adjacent to the complex 2 to receive raw material for products for
each plant in the complex 2 and to deliver products from each
plant, so that the common port facility 4 is commonly used for the
plants in the complex 2.

hot water, and steam and so on as products from each plant in the
complex 2 to the urban communities 20, industrial parks 30 in which
other industrial plants are concentrated, airport 40 and so on.
With this product delivery facility 5, not only are products from
the respective plants once collected at the product delivery
facility 5 via the transporter 3 delivered to the urban communities
20 and the like, but also it is a matter of course that products
from respective plants are delivered directly to the urban
communities 20 and the like.
[0067] Further, the waste material treatment facility 6 is also
constructed to recycle waste materials generated at the urban
communities 20, the industrial parks 30, the airport 40 and so on.
In this case, waste materials from the urban communities 20 and the
like are collected at the waste material treatment facility 6 once,
and are recycled after transport to each plant in the complex 2 via
the transporter 3. For example, when the waste material treatment
facility 6 is a furnace, required power is obtained from oil-fired
power plant P, and ash from the furnace can be recycled in the
cement plant C also. In addition to this, it is possible to recycle
waste materials from the urban communities 20 and the like after
direct transport to each plant also, as a matter of course.

independently outside of the plant, can completely or partly be
recycled in the complex 2.
[0073] Still further, the waste liquid Wr4 is treated in the waste
liquid treatment facility 8 which is commonly used for respective
