Flooding of peatlands occurs within the framework of the International Climate Initiative. The European Climate Initiative supports projects aimed at protecting the climate and ensuring a favorable living environment. Investment projects to restore wetlands should take into account environmental risks for the purpose of sustainable development of the region. Ryazan Meshchera is one of the main places for water reclamation activities. The main goal of flooding drained peatlands is to reduce their fire danger. To as...

The problem of optimization of design and regime parameters of PSA unit?s operation with regard to an economic criterion (total costs, profit, etc.) and fulfillment of design and technologicalechnologicalechnological echnologicalechnologicalechnologicalechnological constraints on the process (purity of the concentrated gas (hydrogen, oxygen), on PSA unit capacity, energy- and resource-saving, etc.) is formulated and solved. The problem?s formulation takes into account: 1) the uncertainty (inaccuracy) of the initia...

A mathematical model of the dynamics of pressure swing adsorption (PSA) process during the separation of multicomponent gas mixtures with the aim of producing hydrogen has been developed. The model allows to calculate the profiles of component concentrations (H2, CO2 and CO) and temperature in gas and solid phases, the pressure and velocity of the gas mixture along the height of the adsorbent depending on time. As a result of the computational experiments, the effect of changes in the temperature, composition, and...
