Opis:
Natural gas is a mixture of hydrocarbons with combustible methane as the main component, the content of which usually exceeds 90. Among the remaining components of natural gas are ethane, propane, butane, nitrogen, carbon dioxide, sulfur compounds. Helium can be also found in some natural gas fields. The composition of natural gas depends on, e.g. the field from which the gas comes, and also way in which it is transported, i.e. pipelines, LNG technology. The quality of natural gas is regulated by respective standards. Gas transmission pipelines are the most popular method, dominating on the international gas market, though LNG technology has recently started to play the more and more prominent role. The intensive development of renewable energy sources is accompanied by the development of the Power to gas technology - the electric energy excess is used for the hydrogen production, which can be directed to the existing natural gas network and such a mixture of natural gas and nitrogen is transmitted. At present transmission pipelines for nitride natural gas Ls and Lw exist in Poland. The aim of this paper is analyzing the influence of natural gas admixtures on the operation parameters of transmission pipelines.

Opis:
Despite all global economic shifts and the fact that natural gas is recognized worldwide as the main and the leading alternative to oil products in transportation sector, there is a huge barrier to switch passenger vehicle segment to natural gas – the lack of refueling infrastructure for natural gas vehicles. The key to solving that problem and providing barrier breaking refueling infrastructure solution for natural gas vehicles (NGV) is home fast refueling units. It operates using natural gas (methane), which is being provided through gas pipelines at client’s home, and electricity connection point. It enables an environmentally friendly NGV’s home refueling just in minutes. The underlying technology is one stage hydraulic compressor (instead of multistage mechanical compressor technology) which provides the possibility to compress low pressure gas from residential gas grid to 200 bar for its further usage as a fuel for NGVs. More than efficiency and convenience, the direct hydraulic compressor technology provides compelling cost and lifetime advantages as well as superior convenience over other solutions. Aims of this article is to compare technical, technological and safety aspects of home refueling units and estimate a perspectives of natural gas vehicles as an alternative for regular vehicles.

Opis:
The production of hydrogen based on excess electricity and transporting it by pipeline as a mixture with natural gas may be an excellent completion of an energy system. When dealing with gas transmission over long distances, gas compression stations become an integral part of the natural gas grid, providing desired pressure of this source of power in pipes. In this paper the effect that hydrogen admixture has on the main parameters of the operation of gas compression stations was described.

Opis:
Natural gas prepared for pipeline transportation must have appropriate parameters described in norms and standards. This entails a restrictive approach to acceptable changes in the composition of the natural gas in pipeline transmission system. The greater number of entry points to the pipeline transmission system causes a greater probability of natural gas diversity in terms of the content of its individual components. It particularly concerns the natural gas sources in which treatment methods are not sufficiently accurate and also imported gas. In specific cases where natural gas with a higher content of heavier hydrocarbons such as propane and butane will enter the transportation system, it is possible for the phenomenon of retrograde (reverse) condensation to occur. The occurrence of the two-phase system significantly worsens the pipeline transport conditions, causing significant pressure drops of transported natural gas. The article examines cases where the phenomenon of retrograde (reverse) condensation occurred in the pipeline transportation of natural gas.

Opis:
In this paper, developed a linear programming model to determine the volume of vessels that will give an optimal return on investment. The solution to the developed model was carried out using the Interior Point algorithm with the help of the MATLAB package. The analysis observed that the production and transporting of the LNG with a vessel of capacity 178,5006m3 would give an optimal profit of 633,640 million USD. And from the results of the analysis, we observed that the decision to take the maximum modern capacity instead of lower capacities yields the highest profit.

Opis:
The natural gas market has changed over the last few years. The approach to commercial relations hitherto was conditioned by the method of supply of this raw material, which was mainly carried out using gas pipelines. Taking into account the fact that natural gas has a six hundred times higher energy density in the form of LNG than in uncompressed form, it is economically justified to transport the resource by more than just traditional gas pipelines. Maritime transport of LNG has become an alternative means of delivering volumes to areas with insufficient gas resources. The article presents general methods of settlement and quality control of LNG in marine loading and receiving terminals. The types of measurements used in LNG settlements carried out on ships and on land are analysed. The aim of the paper was to analyse the way of ensuring and supervising the quality of LNG transported to the ship and to design an assessment form and monitor the stability of the quality level of LNG supplies with the use of a single measurement control card. It is proposed to use a two-track numerical stabilisation control card for single measurements and a mobile range IX-MR (Xi-MR).

Opis:
Among other conventional energy sources, on the present level of technology development, natural gas is a primary energy source, which has the lowest level of harmful substances emission both for humans and the environment. Comparing to coal - in the burning process of the natural gas there is a very low emission of pollutants: trace amounts of sulphur and carbon dioxide, which established natural gas' position as an environmentally friendly fuel. CO2 emission expressed in CO2 kg/kWh of fuel during burning process of lignite amounts to 0.40; of hard coal - 0.33; of heavy fuel oil - 0.28; of light fuel oil - 0.26 and 0.20 of gas. The use of natural gas as a fuel instead of other kinds of fossil fuels, e.g.: coal, results in decreasing harmful substances emission. Therefore, CO2 emission or sulphur dioxide emission is much smaller. What's more, lower CO2 emission means decreasing the greenhouse effect and lower sulphur dioxide emission reduces the amount of acid rains. Natural gas system is different than networks, such as water supply, heat or electricity in such way that, in Poland it is necessary to acquire most of the distributed medium from the sources located outside Polish borders.
Zastosowanie gazu ziemnego jako paliwa w miejsce innych rodzajów paliw kopalnych, takich jak, np. węgiel, przynosi efekt w postaci ograniczenia emisji szkodliwych substancji do atmosfery. Zmniejszeniu ulega bowiem, między innymi, emisja dwutlenku węgla, dwutlenku siarki. Zmniejszanie wielkości emisji dwutlenku węgla do atmosfery wpływa na obniżenie skali zjawiska cieplarnianego. Natomiast zmniejszenie emisji dwutlenku siarki skutkuje redukcją ilości kwaśnych deszczy Podstawowym problemem zaopatrzenia w gaz ziemny odbiorców w Polsce jest to, że zasoby tego surowca energetycznego zlokalizowane na terenie naszego kraju nie są w stanie zaspokoić istniejących zapotrzebowań. Koniczne jest więc importowanie gazu ziemnego. Dostawy gazu ziemnego, w zależności od dostępnej infrastruktury gazowej, wielkości danego rynku zbytu, odległości od źródła gazu oraz innych uwarunkowań, mogą być realizowane z wykorzystaniem rurociągów (gazociągów) lub też drogą morską (statki dostarczające LNG z ang. Liquefied Natural Gas, statki dostarczające CNG z ang. Compressed Natural Gas). Podstawową zaletą łańcucha dostaw CNG są stosunkowo niewielkie nakłady związane z infrastrukturą załadunkową i rozładunkową. Niemniej największym nakładem kapitałowym jest flota statków CNG (około 80%). Inne elementy łańcucha dostaw związane z wydobyciem i obróbką gazu ziemnego jak również z rozprowadzeniem gazu do odbiorców końcowych gazociągami są tożsame z innymi sposobami dostaw gazu ziemnego. W pracy przedstawiono przegląd proponowanych rozwiązań umożliwiających transport morski gazu ziemnego w postaci CNG. Przedstawione rozwiązania to w chwili obecnej koncepcje, a załączone rysunki statków przedstawiają możliwy wygląd statków CNG z zastosowaniem różnych technologii.
