    applied sciences Article A Comparative Exergoeconomic Evaluation of the Synthesis Routes for Methanol Production from Natural Gas Timo Blumberg 1,*, Tatiana Morosuk 2 and George Tsatsaronis 2 ID 1 Department of Energy Engineering, Zentralinstitut El Gouna, Technische Universität Berlin, 13355 Berlin, Germany 2 Institute for Energy Engineering, Technische Universität Berlin, 10587 Berlin, Germany; [email protected] (T.M.); [email protected] (G.T.) * Correspondence: [email protected]; Tel.: +49-30-314-23343 Received: 30 October 2017; Accepted: 20 November 2017; Published: 24 November 2017 Abstract: Methanol is one of the most important feedstocks for the chemical, petrochemical, and energy industries. Abundant and widely distributed resources as well as a relative low price level make natural gas the predominant feedstock for methanol production. Indirect synthesis routes via reforming of methane suppress production from bio resources and other renewable alternatives. However, the conventional technology for the conversion of natural gas to methanol is energy intensive and costly in investment and operation. Three design cases with different reforming technologies in conjunction with an isothermal methanol reactor are investigated. Case I is equipped with steam methane reforming for a capacity of 2200 metric tons per day (MTPD). For a higher production capacity, a serial combination of steam reforming and autothermal reforming is used in Case II, while Case III deals with a parallel configuration of CO2 and steam reforming. A sensitivity analysis shows that the syngas composition significantly affects the thermodynamic performance of the plant. The design cases have exergetic efficiencies of 28.2%, 55.6% and 41.0%, respectively.

The growing importance and volumes of liquefied natural gas for transportation over long distances come as a consequence of this tendency. The liquefaction of natural gas requires a high amount of energy that can be recovered during the re-gasification phase. In this paper, a novel approach for this purpose is presented, where the main feature is the use of a combination of Rankine and Brayton cycles while retaining natural gas as the only working fluid of the system. The proposed system is optimized for cost and exergy efficiency using a bi-level multi-objective optimization procedur e, where the master level is setup as a nonlinear optimization problem and solved using an evolutionary algorithm , while the slave level as a mixed integer-linear programming problem.

  • D for the Liquefaction and Regasification Processes
    LNG R&D for the Liquefaction and Regasification Processes Author: Marcello De Falco, Associate Professor, University UCBM – Rome (Italy) 1.Theme description Liquefied Natural Gas (LNG) is used for transporting natural gas (NG) to distant markets, not supplied by NG grid connecting the extraction/production point to the users. Basically the LNG process is composed by the following steps[1]: Extracted natural gas is liquefied in the production field or in a close site, after removing the impurities. Usually, in the liquefaction process the gas is cooled to a temperature of approximately -162°C at ambient pressure. Then, the LNG is loaded onto double-hulled ships which are used for both safety and insulating purposes and transported to the receiving harbor. As arrived, the LNG is loaded into well-insulated tanks and, then, re-gasified in specific plants. At the end, the re-gasified NG is fed to the pipeline distribution system and delivered to the end-users. But, the high production, transportation and storage costs have reduced the LNG technology spread to specific cases in which there are not other cheaper ways to transport the NG. But, the market and political issues related to the NG are increasing the interest on this alternative transportation technology, which has the benefits of enlarging the potential markets for sellers and the potential suppliers for the buyers (refer to Figure 1). The growing interest has led to greater and greater investments on LNG Research & Development and on its applications. Fig. 1 – Global LNG demand[2] In the following, some of the technologies and innovations related to the LNG production, the transportation and the regasification fields are reported and assessed.

  • GTL Or LNG: Which Is the Best Way to Monetize “Stranded” Natural Gas?
    388 Pet.Sci.(2008)5:388-394 DOI 10.1007/s12182-008-0063-8 GTL or LNG: Which is the best way to monetize “stranded” natural gas? ＊ Dong Lichun, Wei Shun’an, Tan Shiyu and Zhang Hongjing School of Chemistry and Chemical Engineering, Chongqing University, Chongqing 400044, China Abstract: A large portion of world’s natural gas reserves are “stranded” resources, the drive to monetize these resources leads to the development of gas-to-liquids (GTL) and liquefied natural gas (LNG) technologies. LNG has the advantage of having been developed for the past 40 years and having an excellent safety record. GTL on the other hand is another option with substantial benefits, but its development stage and commercial viability are far behind LNG. This paper presents a techno-economic comparison of GTL with LNG, including technical development, plant effi ciency, market potential for the products, and capital cost for the infrastructure. The aim is to give an overall view on both LNG and GTL and provide a perspective on the profi tability of these two technologies. Key words: GTL (gas to liquids), LNG (liquefi ed natural gas), “stranded” natural gas 1 Introduction LNG and GTL serve different energy markets with different marketing systems, policies and strategies. The Natural gas is playing a more and more important role comparison between LNG and GTL is the most prominent in the supply of energy for both industrial and domestic use. debate for resource owners, developers and investors The total global annual gas consumption is forecast to rise alike. Several factors have to be considered to evaluate to 4.59 trillion cubic meters by 2020 with an annual increase the project economics.

  • Methane Number Improvement of Gas from LNG Regasification Unit
    E3S Web of Conferences 67, 04033 (2018) https://doi.org/10.1051/e3sconf/20186704033 3rd i-TREC 2018 Methane Number Improvement of Gas from LNG Regasification Unit Danianto Hendragiri Tjojudo1 and Sutrasno Kartohardjono2,* 1Department of Procurement for Primary Energy and Business Development, PT Indonesia Power - Kantor Pusat, Jl. Jend. Gatot Subroto Kav 18, Jakarta 12950, Indonesia. 2Intensification Process Laboratory, Department of Chemical Engineering Universitas Indonesia, Kampus UI Depok 16424, Indonesia. Abstract. Methane Number (MN) is one of quality requirement of gas as fuel for gas engine, which indicates fuel capability to avoid knocking in the engine. Higher MN provides better quality of gas for gas engine. Natural gas with higher methane (CH4) and fewer higher hydrocarbon, tends to have higher MN score. This study aims to obtain heating methods of LNG to produce vapor that has appropriate MN as a fuel gas supply to gas engine. The simulation for LNG regasification prepared is an approach to the design of the existing regasification facility of the power plant in Bali. The temperature ranges for LNG heating simulation were obtained based on saturated temperatures of LNG phase envelopes. In the simulation. to obtain a certain MN value can be conducted by adjusting the temperatures at two different values i.e. above -110 and below - 80 . To produce LNG vapor that has MN of 80 either through higher temperature of heating (HT heating) or lower temperature of heating (LT heating) requires more energy℃ than direct heating℃ without MN improvement. Heat loading for LT heating is higher than HT heating due to more temperature defference between LT and heating fluid temperatures.

    Using cold energy of the LNG in the integrated process of gasification and electric energy production Milan Zlatkovikj Thesis to obtain the Master of Science Degree in Energy Engineering and Management Supervisor: Prof. Henrique Anibal Santos de Matos Examination Committee Chairperson: Prof. Edgar Caetano Fernandes Supervisor: Prof. Henrique Anibal Santos de Matos Member of the Committee: Eng. Rui Marmota November 2017 i Acknowledgements Getting close to finalizing this work, I want to express my gratitude to the people that helped me in making it. First of all, I want to thank my supervisor professor Henrique Matos and Antonio Domingues. Their in-depth knowledge of this thematic was the reason it started in the first place. The experience of process integration and research work from professor Matos helped me in the analytical part of this work. On the other side, Antonio’s vast experience in the oil and gas industry helped me to understand how the LNG industry works and the terminals in general. Their technical expertise is undeniable. However, during this work, I realized that even with the best engineering skills some projects might get stuck, due to other non-related issues, that every student ocassionally evidents. For their help on this matter, I am even more grateful. The encouragement from professor Matos in the periods when the work wasn’t going the best has great contribution, that now is finally coming to an end. On the other side Antonio’s calmness and patience showed me that for some work time and patience are a must. I would like to thank to the colleagues that worked during the same period in LabSOP at Tecnico.
