Energy efficient design of membrane processes by use of entropy production minimization
(Journal article; Peer reviewed, 2018)To minimize entropy production means to reduce the lost work in a process, and to optimize the use of energy resources. Due to the need for re-compression, membrane units for separation of CO2 from natural gas require large ... -
Enhanced single-loop control of a moving bed temperature swing adsorption CO2 capture process
(Peer reviewed; Journal article, 2023)Using a model in gPROMS, we study a Zeolite 13X-based moving bed temperature swing adsorption (MBTSA) process designed to capture CO2 from a coal-fired power plant. Two enhanced single-loop control strategies were compared ... -
A flexible and robust modelling framework for multi-stream heat exchangers
(Peer reviewed; Journal article, 2013)Heat exchangers are important units in most industrial processes. They involve physical phenomena such as condensation and evaporation including several boiling regimes. Different types of heat exchangers constructed for ... -
Minimizing total annualized cost per tonne of feed processed of a semicontinuous distillation process utilizing data-driven model predictive control
(Peer reviewed; Journal article, 2024)Semicontinuous distillation is a separation technique used to purify multicomponent mixtures with low to medium throughput. This research addresses the problem of designing a Data-driven Model Predictive Control (MPC) ... -
Model predictive control for combined cycles integrated with CO2 capture plants
(Peer reviewed; Journal article, 2021)Flexible thermal power plants integrated with CO2 capture systems can balance the intermittent power generation of renewable energy sources with low-carbon electricity. Among these power systems, natural gas combined cycles ... -
Model reformulations for Work and Heat Exchange Network (WHEN) synthesis problems
(Journal article; Peer reviewed, 2019)The Duran-Grossmann model can deal with heat integration problems with variable process streams. Work and Heat Exchange Networks (WHENs) represent an extension of Heat Exchange Networks. In WHEN problems, the identities ... -
A novel cost-effective silica membrane-based process for helium extraction from natural gas
(Peer reviewed; Journal article, 2019)Natural gas reserves with 0.3–2 mol% helium are considered as the only viable source for this noble gas. Currently, cryogenic separation is used to extract helium, but it is energy-intensive. While membrane-based separation ... -
Optimal cryogenic processes for nitrogen rejection from natural gas
(Journal article; Peer reviewed, 2018)Nitrogen rejection processes are usually needed for two natural gas sources: sub-quality natural gas reserves and produced gas from enhanced oil/gas recovery technologies. The nitrogen content of natural gas in the former ... -
Optimization and analysis of different liquid air energy storage configurations
(Journal article; Peer reviewed, 2022)Energy storage technologies are required to ensure stability of energy systems when the share of renewable energy forms (wind and solar) is increasing. Liquid air energy storage (LAES) is a promising technology for storing ... -
Optimization of helium extraction processes integrated with nitrogen removal units: A comparative study
(Journal article; Peer reviewed, 2019)Helium is regarded as a vital gas to various industries such as medicine, aircraft manufacturing, electronics and fiber optics fabrication. Currently, natural gas reserves are considered the only viable resource for this ...
