Increasing demand for new energy sources requires the use of new substances in the production of energy or at least innovative application of the already known compounds. Considering the above, LNG (Liquefied Natural Gas) is more and more often used as fuel, as the growing pollution of the environment and rapid climate changes force the reduction of emissions of sulphur and nitrogen oxides to the environment. Liquid methane no longer contains sulphur oxides in any form because they are removed during the gas metha...

With the increasing levels of pollution, it is necessary to take actions aiming at reducing emissions of harmful substances to the environment. Unfortunately, increasing demand for new goods and energy does not contribute to the decrease of concentration of harmful substances in soil, water or air. Unexpected uncontrolled releases of chemicals caused by breakdowns in production plants are also a detrimental factor. Adding exhaust and nitrogen oxide emissions from vehicles, the situation seems to be hard to contain...

At the age of an increasing demand for energy we reach to an ever wider range of substances giving a possibility of its generation. A constant need for energy supplies is so strong that we are not prevented by the danger related to the storage or transport of such substances. Although we try to eliminate any risks, even a small human error may contribute to a tragedy. In the case of substantial and sudden depressurization it is impossible to conduct in situ tests at a large scale. An attempt at conducting an in si...

The article concerns the problems occurring in the course of modelling risk areas in the course of hazardous substances propagation. Defining risk areas is a task of the utmost importance with respect to the safety of human lives. Modelling of explosion risk areas is not easy, particularly because we consider a situation in which significant amounts of hazardous substances are released. However, in order to define such conditions, a series of factors affecting the modelling of risky situations were presented in th...
