New Ways for the Advanced Quality Control of Liquefied Natural Gas

Currently, gas chromatography is the most common analytical technique for natural gas (NG) analysis as it offers very precise results, with very low limits of detection and quantification. However, it has several drawbacks, such as low turnaround times and high cost per analysis, as well as difficulties for on-line implementation. With NG applications rising, mostly thanks to its reduced gaseous emissions in comparison with other fossil fuels, the necessity for more versatile, fast, and economic analytical methods has augmented. This work summarizes the latest advances to determine the composition and physico-chemical properties of regasified liquid natural gas, focusing on infrared spectroscopy-based techniques, as well as on data processing (chemometric techniques), necessary to obtain adequate predictions of NG properties.

Rollover of Liquid Natural Gas in a Storage Tank: A Numerical Simulation

In the filling and transportation processes of liquefied natural gas (LNG), the safety of LNG storage tanks is compromised because of rollover phenomenon. As such, the rollover factors of LNG in a storage tank should be identified to prevent or weaken the rollover intensity of LNG. In this study, the rollover behavior of LNG in a storage tank is numerically simulated. The density of the two layers in a LNG storage tank is related to temperature in our numerical model. It is found that the greater the significant initial density difference (range of 1-12 kg·m-3) is, the more obvious the LNG rollover will be. A density difference of 7.5 kg·m-3 is found as the critical density difference in the present work. When the initial density difference exceeds the critical density difference, the LNG rollover coefficients increase dramatically. Moreover, an LNG rollover model with two daughter models is proposed, which are divided by the critical initial density difference, i.e., a cubic relationship between rollover coefficients and the initial density difference when the density difference is less than 7.5 kg·m-3 and secondly, a linear relationship between the rollover coefficient and the double exponential functions when the density difference is larger than 7.5 kg·m-3.

Policies for Improving PM2.5 Particles and GHGs Emissions in a Maritime Port of Taiwan: Evidence Based on the INDC and GGRMA Regulations

The impact of possible emission reduction policies designed to reduce port emissions in the Port of Kaohsiung in Taiwan was analyzed, focusing on ways to reduce air pollution from CO2, CH4, N2O, PM10, PM2.5, NOx, and SOx generated by vessels, cranes, and truck tractors in the port. This paper was set up in two stages to determine how pollution reduction policies could reach the 2030 and in 2050 goals. The results showed that emissions of CO2, CH4, N2O, PM10, PM2.5, NOx, and SOx could be reduced by 46%, 26%, 25%, 77%, 77%, 76%, and 68%, respectively, in the first stage (in 2030, INDC), and by 57%, 59%, 53%, 79%, 79%, 80%, and 69%, respectively, in the second stage (in 2050, GGGRMA), as compared to 2005 data. This paper concludes as follows: (1) for vessels, the use of liquid natural gas is the best way to reduce GHGs when navigating by water; (2) for bridge cranes, electrification is the better policy during operation; (3) in the case of truck tractors, the generation of battery-electric power is the best way to reduce emissions. These policy proposals for improving air quality can be applied to all ports in Taiwan.

Global Liquified Natural Gas Trade under Energy Transition

With the recent rising attention and debates on the role of natural gas, especially liquid natural gas, in energy transition, it is critical to have a consistent approach in assessing uncertainties and dynamics in the global gas market during the next two to three decades. There are two objectives of this paper. The first one is to estimate and discuss the impacts of the global liquified natural gas (LNG) trade under a low-carbon scenario using a partial equilibrium model. The second objective is to discuss the role of a structural economic model in empirical analysis and strategy design under a regime shift, such as an energy transition, for the global natural gas market.

DAMPAK PROSES RESETTLEMENT AREA VILAGES TERHADAP PERUBAHAN SISTEM SOSIAL EKONOMI MASYARAKAT (Studi Pada Masyarakat Kampung Tanah Merah Kabupaten Teluk Bintuni)

BP LNG Tangguh adalah salah satu Multi National Corporation yang saat ini melakukan kegiatan ekplorasi gas alam cair (liquid natural gas) di Kabupaten Teluk Bintuni Provinsi Papua Barat. Kehadiran BP LNG Tangguh di Kabupaten Teluk Bintuni terhitung sejak tahun 2002 hingga saat ini. Kampung Tanah Merah adalah salah satu dari beberapa kampung di Teluk Bintuni yang terkena dampak dari kegiatan operasional BP LNG Tangguh karena areal tersebut dijadikan sebagai lokasi pembangunan kilang gas. Pembangunan kilang gas alam cair di areal Kampung Tanah Merah menjadi salah satu alasan kunci bagi BP Tangguh untuk merelokasi warga Tanah Merah dari kampung mereka ke lokasi baru yang dipilih. Pemilihan lokasi bagi masyarakat Tanah Merah dilakukan berdasarkan persetujuan dari berbagai pihak dengan menentukan lokasi seluas 200 Ha disebelah Kali Saengga yang merupakan wilayah Kampung Saengga. BP Tangguh memfasilitasi semua proses perpindahan penduduk mulai dari pembangunan pemukiman, sarana pra sarana dan memfasilitasi proses perpindahannya. Perpindahan masyarakat Tanah Merah dari kampung lama ke kampung baru tentunya menimbulkan permasalahan dimana lokasi yang dipilih tidak memiliki potensi baik lahan pertanian maupun areal melaut bagi masyarakat. Masyarakat mengalami perubahan pada kondisi sosial ekonomi karena sebelum direlokasi mereka bekerja sebagai nelayan penangkap udang dengan penghasilan yang sangat cukup bagi mereka. Setelah dipindahkan ke kampung baru mereka tidak lagi dapat menangkap udang namun mereka dipaksa bekerja sebagai petani. Kondisi tanah dan luasan lahan yang disediakan untuk lokasi pertanian tidak memadai sehingga tidak memberikan hasil pertanian yang baik bagi masyarakat. Masyarakat tidak dapat menyesuaikan diri dengan pekerjaan sebagai petani dan sebagai akibatnya mereka mengalami penurunan tingkat pendapatan.

Pandemic State Failure, Hydrocarbon Control, and Indigenous Territorial Counteraction in the Peruvian Amazon

During the COVID-19 pandemic, the Peruvian government failed to protect its sparsely populated Amazon region. While infections were still rising, resource extraction was quickly approved to continue operations as a declared essential service that permitted an influx of workers into vulnerable indigenous territories despite weak or almost absent local healthcare. This article analyzes territorial counteraction as an indigenous response to pandemic national state failure, highlighted in a case of particularly conflictive stakes of resource control: Peru’s largest liquid natural gas extraction site Camisea in the Upper Amazon, home to several indigenous groups in the Lower Urubamba who engaged in collective action to create their own district. Frustration with the state’s handling of the crisis prompted indigenous counteraction to take COVID-19 measures and territorial control into their own hands. By blocking boat traffic on their main river, they effectively cut off their remote and roadless Amazon district off from the outside world. Local indigenous control had already been on the rise after the region had successfully fought for its own formal subnational administrative jurisdiction in 2016, named Megantoni district. The pandemic then created a moment of full indigenous territorial control that openly declared itself as a response and replacement of a failed national state. Drawing on political ecology, we analyze this as an interesting catalyst moment that elevated long-standing critiques of inequalities, and state neglect into new negotiations of territory and power between the state and indigenous self-determination, with potentially far-reaching implications on state-indigenous power dynamics and territorial control, beyond the pandemic.
