The success of long-term gas sales contracts is largely related to the ability of the seller and the buyer to adapt the terms of the contract to their conditions, infrastructure, facilities and market. If the buyer's demand changes from season to season and seasonally fluctuates, problems and complexities arise for the seller and he may need to provide the excess capacity to produce, refine and...
the promotion of oil and gas industry of a country or region requires foreign and longterm investments. ensuring demand security constitutes one of the major driving forces for promoting investments in oil and gas sectors. our main question is to understand the upcoming energy demand security in the caspian markets. just like supply security, energy demand security cannot be affected mainly by ...
the ability of artificial neural network (ann) for estimating the natural gas demand load for the next day and month of the populated cities has shown to be a real concern. as the most applicable network, the ann with multi-layer back propagation perceptrons is used to approximate functions. throughout the current work, the daily effective temperature is determined, and then the weather data w...
One of the issues concerning the replacement of natural gas by green gas is the seasonal pattern of the gas demand. When constant production is assumed, this may limit the injected quantity of green gas into a gas grid to the level of the minimum gas demand in summer. A procedure was proposed to increase the gas demand coverage in a geographical region, i.e., the extent to which natural gas dem...
nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
The purpose of this study was to investigate the photocatalytic oxidation of a reactive azo dye and determine the improvement in the biodegradability when photocatalytic oxidation was used as a pretreatment step prior to biological treatment. The results obtained from the experiments adding H2O2/TiO2 show that the highest decolorisation rate is provided by the combination of (UV+TiO2+H2O2). The...
Estimating Oil Products Demand by State-space Model and Relevant Guidelines for Price Liberalization
The purpose of this paper is to estimate oil products demand by the state-space model, taking into account the implications for price liberalization using the Kalman filter technique in the framework of a time-varying pattern. For this purpose, we use the data of the Energy Balance Sheet and the National Iranian Oil Refining and Distribution Company during the period of 1994-2017. Our model res...
The main target of this of this research is to present the general architectural sub-system model of household's gas demand and to identify different variables affecting gas demand. The factors and variables identified from the subject literature have been analyzed using metasynthesize methodology and appropriate classification and prioritization has been done through content analysis. The stat...
Water samples were collected from river Pandu at six stations where human and animal activities were high. Composite samples were analyzed for dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) , pH values during dry and wet seasons as well as the harmattan period. The total data points were used to establish relationships between the parameters and data were a...
