Data-Driven Robust Optimal Operation of Thermal Energy Storage in Industrial Clusters
(Peer reviewed; Journal article, 2020)Industrial waste heat recovery is an attractive option having the simultaneous benefits of reducing energy costs as well as carbon emissions. In this context, thermal energy storage can be used along with an optimal operation ... -
Evolutionary Algorithm to Support Field Architecture Scenario Screening Automation and Optimization Using Decentralized Subsea Processing Modules
(Journal article, 2021)Manual generation of test cases and scenario screening processes, during field architecture concept development, may produce a limited number of solutions that do not necessarily lead to an optimal concept selection. For ... -
Extracting Valuable Information from Big Data for Machine Learning Control: An Application for a Gas Lift Process
(Journal article; Peer reviewed, 2019)The present work investigated the use of an echo state network for a gas lift oil well. The main contribution is the evaluation of the network performance under conditions normally faced in a real production system: noisy ... -
Multiple-Input Single-Output Control for Extending the Steady-State Operating Range—Use of Controllers with Different Setpoints
(Journal article; Peer reviewed, 2019)This paper deals with a case when multiple inputs are needed to cover the steady-state operating range. The most common implementation is to use split range control with a single controller. However, this approach has some ... -
Ontology-Based Process Modelling-with Examples of Physical Topologies
(Journal article, 2021) -
Real-Time Optimization under Uncertainty Applied to a Gas Lifted Well Network
(Journal article; Peer reviewed, 2016)In this work, we consider the problem of daily production optimization in the upstream oil and gas domain. The objective is to find the optimal decision variables that utilize the production systems efficiently and maximize ... -
Sensitivity-Based Economic NMPC with a Path-Following Approach
(Journal article; Peer reviewed, 2017)We present a sensitivity-based predictor-corrector path-following algorithm for fast nonlinear model predictive control (NMPC) and demonstrate it on a large case study with an economic cost function. The path-following ... -
Study of various aqueous and non-aqueous amine blends for hydrogen sulfide removal from natural gas
(Journal article; Peer reviewed, 2019)Various novel amine solutions both in aqueous and non-aqueous [monoethylene glycol (MEG)/triethylene glycol(TEG)] forms have been studied for hydrogen sulfide (H2S) absorption. The study was conducted in a custom build ... -
Thermo-Fluidic Characteristics of Two-Phase Ice Slurry Flows Based on Comparative Numerical Methods
(Journal article; Peer reviewed, 2019)Ice slurry is a potential secondary refrigerant for commercial refrigeration systems because of its remarkable thermal properties. It is necessary to optimize the heat transfer process of ice slurry to reduce the energy ... -
Vapor Liquid Equilibrium Measurements of Two Promising Tertiary Amines for CO2 Capture
(Journal article; Peer reviewed, 2019)Post combustion CO2 capture is still a rather energy intense, and therefore expensive, process. Much of the current research for reducing the process energy requirements is focused on the regeneration section. A good ...
