Techno-Economic Analysis of ORC in Gas Compression Stations Taking Into Account Actual Operating Conditions

Region sown areas portfolio optimization taking into account crop production economic risk

Grain production is one of the Ukrainian agro-industrial complex main branches. An indicator of the grain production efficiency is its profitability. It is characterized by significant annual fluctuations that induce risk. Redistribution of existing grain crops areas taking into consideration their profitability can bring to increase of production efficiency. The paper observes Markowitz’s opti...

Exergy Recovery in Gas Pressure Compression Stations (GPCSs)

The exergy analysis is a proper method for performance evaluation of industrial systems. A generic and detailed analysis of the GPCSs on the second gas pipeline of Iran  is made by the means of exergy. The two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. Steady state equations regarding the second law of ther...

Performance of Photovoltaics Under Actual Operating Conditions

Techno-Economic Assessment of Different Inlet Air Cooling Systems in Warm Dry & Wet Climate Stations

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

Optimization of energy consumption and offering a procedure for cooling gas compression facilities at gas compression stations

One of the most important methods of transporting natural gas in Iran and other parts of the world is the utilization of a network of pipelines. Compression station and turbo compressor units play an important role in gas supply through pipelines. One of the primary concerns in these units is the reduction of fuel consumption. By cooling of exhaust gas from the source station, the pressure ...
