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 Prl, 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 Wrl 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 Wrl 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.
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.
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 Rcl 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.

The product delivery facility 5 is, as explained above, mounted to supply gasoline, kerosene, gas oil, and further power, 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.
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.

Further, sludge Wrl, spent catalyst waste Wr2, acid gas Wr3 that are generated in the oil refining plant R are supplied to the cement plant C as an auxiliary raw material or a fuel. Therefore, these waste materials, which have conventionally been disposed of independently outside of the plant, can completely or partly be recycled in the complex 2.
Still further, the waste liquid Wr4 is treated in the waste liquid treatment facility 8 which is commonly used for respective plants in the complex 2. On the other hand, exhaust gas Gr generated in the oil refining plant R is treated at the waste gas treatment facility 9 which is commonly used for respective plants in the complex 2.
As described above, the oil-fired power plant P generates power Pp by rotation of a turbine by steam generated from heavy oil or residues Fp. This heavy oil or residues Fp are the residues Pr4 which are supplied from the oil refining plant R through pipe lines as the transporter 3. In addition, in the oil-fired power plant P also, in the same manner as the oil refining plant R, waste liquid Wp is treated at the waste liquid treatment facility 8, and exhaust gas Gp at the waste gas treatment facility 9.
The steelmaking plant S produces the product Ps from scrap Rs as a raw material through an electric arc furnace, a continuous foundry, and a rolling mill. The power Es consumed in the electric arc furnace, the continuous foundry, and the rolling mill is supplied from the oil-fired power plant P through electrical wires as the transporter 3. Further, as the heavy oil Fs consumed in the plant, residues Pr4 supplied from the oil refining plant R through the transporter 3 is used. Still further, slag Wsl and dust Ws2 that are generated in the steelmaking plant S are recycled by using them as raw materials in the cement plant C. As a result, with the present invention, the slag Wsl and dust Ws2, which have conventionally been disposed of independently outside of the steelmaking plant S, can be recycled within the complex 2.
As described above, the cement plant C mainly produces Portland cement Pc by adding gypsum Rc2 and the like to cement clinker which is obtained through burning of raw materials such as limestone Rcl with heavy oil Fc as fuel. This gypsum Rc2 is supplied from the waste gas treatment facility 9. Further, in addition to limestone Rcl, the sludge Wrl and spent catalyst waste Wr2 that are generated in the oil refining plant R are used as raw materials. Still further, the slag Wsl and dust Ws2 that are generated in the steelmaking plant S described below as a byproduct and a waste material are used as raw materials. As a result, it is possible to completely or partially recycle within the complex 2 byproducts and waste materials generated from the oil refining plant R and the steelmaking plant S.
Further, in the cement plant C, the heavy oil Fc used as a fuel is the residues Pr4 that are supplied from the oil refining plant R through pipe lines as the transporter 3; in the same manner, acid gas Wr3 generated from the oil refining plant R can be used as a fuel.
