Nowadays, the optimal control of a heat integrated industrial plant becomes one of the most important research areas in the chemical industry. There are at least two main reasons why this topic is interesting: first, the reduction of production costs applying the heat integration techniques and second, process optimization through advanced control alternatives, when taking into account the impr...

The popularity of vehicles and the increased time spent in cars with air conditioning systems has led to regulations many countries that require use environmentally friendly refrigerants minimal global warming zero ozone depletion potential (GWP ODP). Cars need high-performance, eco-friendly reduce their impact on environment, lower fuel consumption, decrease carbon emissions. aim current work ...

Natural gas (NG) requires treatment to eliminate sulphur compounds and acid gases, including carbon dioxide (CO2) hydrogen sulphide (H2S), ensure that it meets the sale transportation specifications. Depending on region is obtained from, concentrations of gases could reach up 90%. Different technologies are available capture CO2 H2S from NG absorb them with chemical or physical solvents; occasi...

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 ...

One of the industries with high potential for energy saving is the petrochemical industry. Ethylene and propylene production plants (olefin plants) – as a part of the petrochemical industry – are very energy intensive. So, any try to improve their energy consumption efficiency could lead to a high amount of energy saving. Iran’s petrochemical industry uses old technologies and components and du...
