  ANÁLISE DA MOVIMENTAÇÃO DA CARGA (SLOSHING) DE GNL E MODELAGEM DE SUA VAPORIZAÇÃO (BOIL-OFF) CONSIDERANDO COMPOSIÇÃO E TIPO DE TANQUE DE NAVIOS METANEIROS (CARRIER), Descrição: http://www.maxwell.vrac.puc-rio.br/26858/26858.PDF The project studies the effect of the LNG cargo movement (sloshing) inside LNG cargo containment tanks with three different geometries (spherical, membrane, prismatic) during transoceanic transportation of this fuel. It is developed a mathematical model of the boil-off rate inside those tanks, varying the composition of LNG exported by six greatest international producers, considering also the thermal isolation of each type of tank geometry. For future work, it is strongly recommended to consider the geometry of the IHI prismatic SPB tank, using actual compositions values of the LNG transported, compositions, instead of average values ​​obtained in the literature; such an actual compositions added to the obtaining enthalpy values ​​from the phase diagram P-h with REFPROP aind ill reduce even more the process uncertainties. Another improvement should consider more maritime routes, like the polar ones, instead of the subtropical route proposed in the present work. Sub-zero polar temperatures are expected to impact the results, which would give an interesting research and quantify this impact. For the purpose of the present work, results could be considered as satisfactory since they are close to those obtained in the open literature. Moreover, considering the high average economic value of the evaporated volume, supposing that the total carrier fleet of about 500 units does not use the BOG for propulsion porposes, an gross economy of about US$ 500,000 could be expected. It is not without reason that GIIGNL and the largest shipping association, BIMCO-30 (International Shipping Association), joined in 2016 to discuss how to deal with the boil-off during the transoceanic LNG voyages.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Doutorado: (1) . , Integrantes: Alan da Silva Esteves - Coordenador / Lucas Carneiro Luz - Integrante.

  Studies on LNG Chain Value: Modeling of the thermal radiation fields emited by LNG pool fires, Descrição: Continue with the research work that made possible the post doctoral intern to invent in 2012 in a previous CNPq Project, a computer code to predict the geometry of a fire solid flame disgorged onto the sea, as well as its surfasse emissive power varying with the flame heigt. The present challenge is to givre a step ahead. It consists of a determination of another mathematical model to calculate thermal radiation (flux) fields propagating and being attenuated by the surrounding atmosphere with a given transmissivity and a give wavelength. These fluxes will propagate and strike surrounding resources in a given distance from the the fire column. In this determination it will be necessary to predict the view fator between emitter and recector objects determined with the Stoke's theorem, considering as well, the the binding of the flame axle (tilt), the flame drag due to wind effects. Such a fields are very important to local Port Authorities (INEA/FEEMA/IBAMA, Marinha do Brasil, etc.) as well as international ones (SIGGTO, USCG, MARAD, IMO, etc.) to predict safe distances and exclusion around onshore cryogenic LNG terminals. Authorities interested in those resuts are FERC, ABS, etc., beside companies such as PETROBRAS.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Alan da Silva Esteves - Coordenador.

New frontiers will be open: (I) new technologies with onboard liquefaction, and (ii) assessment / vulnerability mapping to define safety zones around ships and LNG cryogenic regasification terminals: loading, processing, liquefaction and transoceanic transport of Liquefied Natural Gas; (iii) It will evolve now for new technologies of cryogenic systems for embarked LNG production in FPSO (Floating Production, Storage and Offloading Vessel) ships, their use and transoceanic transport LNG tankers. A criteria will be developed to evaluate, correlate and compare parameters and characteristics of liquefaction processes for shipped Natural Gas (NG) and innovations in LNG carriers with cryogenic tanks spherical (Kvaerner Moss ), double membrane (Gaztransport & Technigaz - GTT No. 96 ), prismatic self-supporting (IHI SPB ), independent self-supporting (Ocean LNG Type B ) [1,2]. Technologies will be investigated seeking to establish a methodology that correlates to common purpose of supporting decision-making processes in choosing parameters. It will proceed with the research work, which culminated with the development in 2012 by then intern postdoctoral CNPq in previous project, of a computational code developed in EES platform. The fire column was then modelled mathematically in its geometry (L / D) at sea and their average radiative emissive power was predicted, varying with the height along the axis of the thermal plume as a result of leakage of LNG damaged vessel, followed by fire. This Project will now proceed with the simulation. But it will be another mathematical model, which will be coupled to the previous one, allowing now to simulate the thermal radiation field (flux) that propagates and is attenuated with a full hemispherical transmittance environment (atmosphere). The novel model from now on will cover the distance between the transmitter and the receiver, the geometric configuration factor between both the inclination (tilt) of the vertical axis of the column and drag (drag) of the base of this column by the action of wind on the sea surface [3]. The determination of this radiation field is absolutely necessary to mark out distances considered safe by national Port Authorities (INEA / FEEMA / IBAMA, Brazil's Navy, etc.) as well as international ones (FERC SIGGTO, US Coast Guard, MARAD, etc.) [4 , 5] for the lease / evacuation of maritime terminals. To the radiation model, two other models will subsequently be coupled: (a) a simulated temperature for the conduction mechanism in the interior of bodies / solids vulnerable resources affected by the field, a dose of thermal radiation (heat between product flow and exposure time); (b) the mapping functions with stochastic error vulnerabilities (percentage) of vulnerable resources will be affected. . , Situação: Em andamento; Natureza: Desenvolvimento. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Alan da Silva Esteves - Coordenador / Edwin Valderrama Campos - Integrante.
