Investigation of the effects of purge gas recycling for increasing methanol production and carbon dioxide reduction on the environment using dynamic simulation

Abstract Nowadays, not only development but also survival requires energy. In today’s world, this energy is supplied through various carriers such as oil, gas, electricity, and renewable Due to the increasing expansion of urban communities industry industrial life, issue environmental pollution excessive increase in greenhouse gases has become one major problems communities. Half all carbon dioxide emissions are generated by fossil fuel power plants. Synthesis which includes dioxide, monoxide, hydrogen, methane, nitrogen, obtained reforming natural gas. This gas used produce valuable products methanol. general, methanol produced from hydrogenation monoxide separately presence zinc oxide copper catalysts a complex mechanism. study, production unit, effect recycling different components unit been investigated using dynamic simulation. Also, amount reduction its effects on environment examined. These studies showed that considering these changes, rate current can be increased about two percent.
