Greenhouse Gases Emissions

Currently, the influence of transport on the environment represents a serious problem, especially in terms of energy consumption and generation of gases causing global warming. The contribution on the topic of comparing energy consumption and greenhouse gases emissions on relation Brno – Jihlava thus aims to describe generation of emissions in the current types of transport and their calculation according to EN 16258:2012. The results of the calculations will be expressed in emission intensity units to the number of passengers transported. The EN 16258:2012 calculations will be applied to passenger rail transport. In particular, energy intensity and generation of greenhouse gases will be monitored in relation to travelling the distance between Brno and Jihlava.

The Impact

Abstract Liquefied petroleum gas (LPG) plays a major role in worldwide energy consumption as a clean source of energy with low greenhouse gases emission. LPG transportation is exhibited through networks of pipelines, maritime, and tracks. LPG transmission using pipeline is environmentally friendly owing to the low greenhouse gases emission and low energy requirements. This work is a comprehensive evaluation of transportation petroleum gas in liquid state and compressible liquid state concerning LPG density, temperature and pressure, flow velocity, and pump energy consumption under the impact of different ambient temperatures. Inevitably, the pipeline surface exchanges heat between LPG and surrounding soil owing to the temperature difference and change in elevation. To prevent phase change, it is important to pay attention for several parameters such as ambient temperature, thermal conductivity of pipeline materials, soil type, and change in elevation for safe, reliable, and economic transportation. Transporting LPG at high pressure requests smaller pipeline size and consumes less energy for pumps due to its higher density. Also, LPG transportation under moderate or low pressure is more likely exposed to phase change, thus more thermal insulation and pressure boosting stations required to maintain the phase envelope. The models developed in this work aim to advance the existing knowledge and serve as a guide for efficient design by underling the importance of the mentioned parameters.
