The question of methodical approach to the distribution of total technological energy consumption between separate kinds of outputs of multi-product manufacture is considered. Such ferrous metallurgy industries include blast furnace process, oxygen, energy, and coke production. The theoretical basis of proposed methodological provisions is Hess's law on thermochemical reactions and its consequences. For manufactures where the products correspond to the types of energy resources and have calorific value, the distribution of energy consumption is carried out according to the weighty volumes of types of products and their heat of combustion (for example, coke production). For industries that have multi-product manufacture of non-combustible products, the distribution of energy consumption between products is based on the weighty volumes of products and their heat capacity (for example, blast furnace iron production). In accordance with the proposed methodological provisions, we present calculation formulas for determining the distribution of total technological energy consumption for separate types of coke and blast furnace production. The results calculations of energy consumption are presented separately for coke, coke-oven gas, and chemical products of coke manufacture as well as for cast iron and furnace slag for blast furnace production. Calculations show a significant reduction of the energy consumption of coke, with regard for the distribution of energy consumption for individual outputs of coke production (by 27.2%) and pig iron in blast furnace production (a decrease in 31.8%.). The proposed methodological provisions for the distribution of total technological energy consumption between separate types of outputs of multi-product industries can be used in such manufactures of oil refining and chemical industry, in the processing industry, in particular, in the production of dairy products, etc. Keywords: energy consumption, multi-product manufacture, coke, coke-oven gas, cast iron, slag, heat of combustion

The performance of Ni/SiO2 Catalysts modified by La2O3, ZrO2 and CeO2 were tested in a BaCo0.7Fe0.2Nb0.1O3-δ (BCFNO) membrane reactor by catalytic partial oxidation of coke oven gas (COG) under atmospheric pressure. The results show that the oxygen permeation flux increased dramatically with Ni/RxOy/SiO2 (R = La, Zr or Ce) catalysts by adding the element of rare earth especially the La during the reforming reaction. At optimized reaction conditions, the dense oxygen permeable membrane had an oxygen permeation flux around 16.4 ml/cm2•min and a CH4 conversion of 99.2% have been achieved at 900 oC.

PurposeThe purpose of this paper is to investigate the performance of coke oven gas (COG)-combined cooling, heating and power (CCHP) system and to mainly focus on studying the influence of the environmental conditions, operating conditions and gas conditions on the performance of the system and on quantifying the distribution of useful energy loss and the saving potential of the integrated system changing with different parameters.Design/methodology/approachThe working process of COG-CCHP was simulated through the establishment of system flow and thermal analysis mathematical model. Using exergy analysis method, the COG-CCHP system’s energy consumption status and the performance changing rules were analyzed.FindingsThe results showed that the combustion chamber has the largest exergy loss among the thermal equipments. Reducing the environmental temperature and pressure can improve the entire system’s reasonable degree of energy. Higher temperature and pressure improved the system’s perfection degree of energy use. Relatively high level of hydrogen and low content of water in COG and an optimal range of CH4volume fraction between 35 per cent and 46 per cent are required to ensure high exergy efficiency of this integration system.Originality/valueThis paper proposed a CCHP system with the utilization of coke oven gas (COG) and quantified the distribution of useful energy loss and the saving potential of the integrated system under different environmental, operating and gas conditions. The weak links of energy consumption within the system were analyzed, and the characteristics of COG in this way of using were illustrated. This study can provide certain guiding basis for further research and development of the CCHP system performance.
