Absorber design in sour natural gas treatment plants: Impact of process variables on operation and economics = Absorberentwurf für Anlagen zur Behandlung von sauren Erdgasen: Einfluss Prozessparameter auf Betriebsführung und Prozesswirtschaftlichkeit [PDF]

open access: yes, 1985
Two models of absorber have been developed which describe the absorption of H2S and CO2 from natural gases by aqueous di-isopropanolamine (DIPA) or methyl-di-ethanolamine (MDEA) solutions. In these models mass transfer, reaction and equilibrium processes

Nonlinear Modeling and Verification of a Heaving Point Absorber for Wave Energy Conversion [PDF]

open access: yes, 2017
Although the heaving Point Absorber (PA) concept is well known in wave energy conversion research, few studies focus on appropriate modelling of non-linear fluid viscous and mechanical friction dynamics.

Modelling a Heaving Point-Absorber with a Closed-Loop Control System Using the DualSPHysics Code

open access: yesEnergies, 2021
The present work addresses the need for an efficient, versatile, accurate and open-source numerical tool to be used during the design stage of wave energy converters (WECs). The device considered here is the heaving point-absorber developed and tested by

Performance Evaluation of Wide-Angle Ultrathin Microwave Metamaterial Absorber with Polarization Independence

open access: yesAdvanced Electromagnetics, 2018
A novel dual-band wide-angle ultra-thin absorber composed of dual closed-concentric ten-point stars with polarization independence is presented in this article. The ten-point stars formed resonators are engraved on low cost FR4 substrate. The EM absorber

Nonlinear Model Reduction by Moment-Matching for a Point Absorber Wave Energy Conversion System

open access: yesJournal of Marine Science and Engineering, 2022
This paper presents a data-driven model reduction by moment-matching approach to construct control-oriented models for a point absorber device. The methodology chosen and developed generates models which are input-to-state linear, with any nonlinear ...

On the Optimization of Point Absorber Buoys

open access: yesJournal of Marine Science and Engineering, 2014
A point absorbing wave energy converter (WEC) is a complicated dynamical system. A semi-submerged buoy drives a power take-off device (PTO), which acts as a linear or non-linear damper of the WEC system.

Numerical Investigation of the Scaling Effects for a Point Absorber

open access: yesWater, 2022
In order to design and evaluate the behaviour of a numerically optimised wave energy converter (WEC), a recommended procedure is to initially study small scale models in controlled laboratory conditions and then progress further up until the full-scale ...

Optimization of energy‐capture performance of point‐absorber wave energy converter

open access: yesInternational Journal of Energy Research, 2022
An optimization process is proposed for improving the energy‐harvesting efficiency of the point‐absorber wave energy converter (WEC) and thus enhancing the utilization of wave energy resources. The multidisciplinary design optimization integration system
