Safety and techno-economic analysis of ethylene technologies
(
Elsevier Ltd
, 2016 , Article)
Recent growth in shale gas production has contributed to the interest in establishing numerous petrochemical plants for shale-gas monetization. The ethylene industry is one of the main beneficiaries of such growth because ...
High-pressure CO2/N2 and CO2/CH4 separation using dense polysulfone-supported ionic liquid membranes
(
Elsevier B.V.
, 2016 , Article)
Four ionic liquids (ILs) were blended with polysulfone (PSF) to produce functional dense polymer-supported IL membranes (DPSILMs). The main aim was to investigate the applicability of the DPSILMs in industrial gas processing ...
Dynamic simulation and optimization targeting emission source reduction during an ethylene plant start-up operations
(
Elsevier Ltd
, 2016 , Article)
Chemical plant flare minimization has been practiced not only during regular operating conditions but also abnormal operations such as start-ups, shutdowns, and process upsets. This paper focuses on introducing a generic ...
Removal of volatile sulfur compounds by solar advanced oxidation technologies and bioprocesses
(
Elsevier Ltd
, 2016 , Article)
The degradations of volatile sulfur compounds (VSCs) by advanced oxidation technology, solar advanced oxidation technology, biological treatment, and the combination of solar advanced oxidation technology and biological ...
Novel methodology for facile fabrication of nanofiltration membranes based on nucleophilic nature of polydopamine
(
Elsevier B.V.
, 2016 , Article)
Novel methodology for facilely fabricating nanofiltration (NF) composite membrane has been successfully developed by employing nucleophilic nature of polydopamine (PDA) chemistry. The self-polymerized PDA coating over ...
Coagulant recovery and reuse for drinking water treatment
(
Elsevier Ltd
, 2016 , Article)
Coagulant recovery and reuse from waterworks sludge has the potential to significantly reduce waste disposal and chemicals usage for water treatment. Drinking water regulations demand purification of recovered coagulant ...
Mathematical modeling based evaluation and simulation of boron removal in bioelectrochemical systems
(
Elsevier B.V.
, 2016 , Article)
Boron removal is an arising issue in desalination plants due to boron's toxicity. As an emerging treatment concept, bioelectrochemical systems (BES) can achieve potentially cost-effective boron removal by taking advantage ...
Innovative method of metal coating of microcapsules containing phase change materials
(
Elsevier Ltd
, 2016 , Article)
Microencapsulation of phase change materials (PCMs) is needed to prevent PCM leaking during melting. However, the low thermal conductivity of the microcapsules shell limits their applications. To enhance thermal conductivity ...
Mathematical modeling assisted investigation of forward osmosis as pretreatment for microbial desalination cells to achieve continuous water desalination and wastewater treatment
(
Elsevier
, 2016 , Article)
Coupling forward osmosis (FO) with microbial desalination cells (MDCs) can lead to some synergistic benefits, i.e. simultaneous water recovery, desalination and removal of COD (chemical oxygen demand). Herein, an FO-MDC ...
Comparative Study of Homogeneous and Heterogeneous Modelling of Water-Gas Shift Reaction with Macro-or Micro-kinetics
(
Elsevier Ltd
, 2016 , Conference Paper)
This paper presents critical studies on water-gas shift reaction (WGSR) kinetic models as well as the modelling approaches of the reactor, in which the reaction is conducted - the packed-bed tubular reactor (PBTR). There ...
