Energy and emission balance of the Lesser Poland Voivodeship in 2020

The article presents the energy balance for the Lesser Poland Voivodeship in 2020. Production, import, input and transformation yield, own consumption of power plants and combined heat and power plants, network losses and consumption in the economic sector (industry, waste), transport (road and rail), buildings (residential and service), as well as in agriculture and forestry are indicated. The following energy carriers: hard coal, crude oil and derivatives (including gasoline, oils, LPG), non-renewable precipitation, system heat and electricity. An estimate of greenhouse gas emissions in 1990 and 2020 in the Lesser Poland Voivodeship is also presented.

Keywords: greenhouse gas emissions, energy scenarios, energy balance

Assessment of the possibility of CO2 capture using post-combustion method

The combustion of fossil fuels in the process of generating electricity causes carbon dioxide emission, which is considered the main anthropogenic reason for global warming. The paper’s subject is assessing the possibilities of CO2 capture based on post-combustion methods. The post-combustion methods such as: chemical absorption, physical separation, membrane separation, and chemical looping, are described.  The thermo-dynamic modelling of a coal-fired supercritical power plant integrated with post-combustion carbon capture installation using the solvent method is performed. The results obtained from the model are used to investigate the impact of the power plant when carbon capture is performed.

Keywords: CO2 emissions, PCCS, amine technologies

Technological aspects of the development of the production of mining link chains

The article presents a short development history of the types of currently produced mining chains and their share in the world market. The development directions of mining link chains were determined in terms of the materials used and strength parameters. The negative impact of some factors that reduce the operational properties of mining link chains has been demonstrated.

Keywords: chain, safety, durability

Autonomous Planetary Rover Kalman

A project presented in the article is a proof of the usefulness of student organizations and its effectiveness in the popularization of advanced technologies as well as solutions in industrial future. Student-developed planetary rover, using Kalman filter and the other algorithms responsible for, among other things, dynamic terrain mapping and pathfinding is capable of non-collision movement in the most challenging environments. Moreover, the rover uses 6DOF arm developed by students to undertake manual actions, such as soil sampling or maintenance tasks with ease. Invention is provided with a drill to be capable of extracting a sample from a depth of 30 centimeters, which is expected to greatly enhance the research of the geological history of the surveyed region. Robot has been tested multiple times on planetary rovers competitions with a success proving the potential of such platforms as one of basis points in space exploration and opportunities in industrial use, especially in hard-to-reach areas of mining. Featured project represents inspiration for future young engineers and scientists by opening perspectives for implementing similar technologies to more efficient and safer operations in industry.
