#### Abstract

Main result of constant development of civilizations is the consumption of enormous quantities of energy. An alternative to conventional energy sources are renewable energy sources (RES). Their main advantages are low harmfulness for the environment and inexhaustible resources. One of RES is gaining energy from biogas. The primary components of biogas are methane and carbon dioxide, and traces: nitrogen, hydrogen sulfide, ammonia. In order to improve the calorific value of biogas, it should be remove primarily carbon dioxide from the mixture. An effective method of removing CO2 from biogas is membrane separation. Membrane methods are often used to gas separation due to their simplicity of operation. These processes rely on the transport of some components of the gas by a semipermeable barrier (membrane) through which one or more species move faster than another or other species. Thanks to the development of the chemistry of plastics has become possible to use various synthetic polymers to receive different types of membrane. The transport of components through nonporous solid membranes is based on the difference in pressure on both sides of the barrier and is described by the solution – diffusion model. Often the experimental gas permeation due to the scale of the project or the related costs are impossible to carry out. In such situations the test perform with the use of models. Mathematical models also apply to optimize these processes. In the thesis there are analyzed two simplified models of separation of mixture CO2/CH4 in membrane module: the model of the ideal mixing on both sides of the membrane (used to describe the separation on flat module) and the model of crossflow (used to describe the separation on spiral wound module). On the basis of the above mentioned models was carried out the calculations to show the influence of various parameters on the degree of purity of biogas. The results of the calculations illustrated in charts. Furthermore, shows the comparison of the model with a perfect mixing with the results of experiment carried out at the Institute of Chemical Engineering PAN in Gliwice consisting of the separation of the mixtures of CO2/N2 with different compositions using polymeric flat module.
