Discharging Part of LNG Liquid Cargo Handling Simulator

Component Modelling of Ship Systems in TRANSAS Liquid Cargo Handling Simulators

Analysis of requirements of physical realism and computational performance for mathematical models, used in liquid cargo handling simulators is presented. Depth of physical modelling, necessary to satisfy the requirements, is considered. Approaches to composition of mathematical models are outlined. Component-based approach with “RanD Model Designer” visual modelling software is described. Comp...

Development of a Cargo Screening Process Simulator: A First Approach

The efficiency of current cargo screening processes at sea and air ports is largely unknown as few benchmarks exists against which they could be measured. Some manufacturers provide benchmarks for individual sensors but we found no benchmarks that take a holistic view of the overall screening procedures and no benchmarks that take operator variability into account. Just adding up resources and ...

Predicting the Liquid Density of Gas Condensates and LNG Mixtures from Equations of State

In this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (LNG) mixtures. In one approach, 12 cubic equations of state (EoSs), comprising the popular Peng-Robinson (PR) and Redlich-Kwong-Soave (RKS), are employed to predict the saturated liquid density of 20 LNG mixtures. In the other approach, these EoS are used in conjunction with a rec...

Single-cycle mixed-fluid LNG process Part I: Optimal design

In this paper, we discuss the design optimization of a relatively simple LNG process; the PRICO process. A simple economic objective function is stated and used on eight different cases with varying constraints. Important constraints are discussed and the results are compared with the commercial PRICO process and with other publications.
