  • Oil/water separation in a novel cyclone separator 
    Stone, Andrew Colin (Cranfield University, 2007-08)
    Conventional bulk oil-water separation is performed in large gravity separators that take up large areas and potentially contain large volumes of hazardous material. An intensified bulk separator has the potential to ...
  • Optimal operation of tubular reactors for naphtha cracking by numerical simulation 
    Gao, G-Y.; Wang, M.; Ramshaw, C.; Li, X-G. (Wiley, 2011-12-06)
    Process gas temperature profile and steam-to-hydrocarbon ratio in the feed have important impact on product yields and coking rate in tubular reactors for naphtha cracking. This study is to evaluate these effects ...
  • Passive slug mitigation by applying wavy pipes 
    Xing, Lanchang (Cranfield University, 2011-08)
    This work is to develop a passive slug mitigation technique based on a novel flow conditioner, wavy pipe, through laboratory experiment and numerical simulation. The wavy pipe has been applied to two types of slug flows: ...
  • Planning for the integrated refinery subsystems 
    Ejikeme-Ugwu, Edith (Cranfield University, 2012-06)
    In global energy and industrial market, petroleum refining industry accounts for a major share. Through proper planning and the use of adequate mathematical models for the different processing units, many profit improving ...
  • Process analysis and improvement of a Claus unit of an existing gas plant 
    Gharsalla, Khaled R. M. (Cranfield University, 2016-05)
    This research is a part of Master degree research programme at Cranfield University to study Claus process and perform process analysis on an existing Sulphur recovery unit in a gas plant. The Mellitah Plant, in Western ...
  • Sand transport in multiphase pipelines 
    Yan, Wei (Cranfield University, 2010-09)
    Over the life of an oil and gas reservoir, it is likely to encounter sand production. In offshore production fields, as there are lack of processing facilities nearby, gas, liquid and sand are often transported together ...
  • Severe slugging and unstable flows in an S-shaped riser 
    Montgomery, J. A. (Cranfield University, 2002-02)
    Severe slugging and unstable flow in an S-Shaped riser has been investigated in three research themes - experiments, criterion modelling and transient code modelling. A series of experiments were carried out on the ...
  • A study o f single and two-phase flows in devices with narrow flow passages 
    Laskey, S. J. (2002-05)
    In many industries, the depressurisation of gas-saturated solutionseis controlled to regulate bubble formation. Carbonated drink dispensers need to depressurise solutions with minimum bubble formation, whereas dissolved ...
  • A study of flow behaviour of dense phase at low concentrations in pipes 
    Koguna, Aminu Ja'Afar Abubakar (2016-09)
    Offshore production fluids from the reservoir are often transported in pipelines from the wellheads to the platform and from the platform to process facilities. At low flow velocity water, sand or liquids like condensate ...
  • A study of gas lift on oil/water flow in vertical risers 
    Brini Ahmed, Salem Kalifa (Cranfield University, 2014-01)
    Gas lift is a means of enhancing oil recovery from hydrocarbon reservoirs. Gas injected at the production riser base reduces the gravity component of the pressure drop and thereby, increases the supply of oil from the ...
  • Study of post-combustion Carbon Dioxide capture for coal-fired plant through modelling and simulation 
    Lawal, Adekola (Cranfield University, 2010-12)
    Fossil-fuel power plants are the largest single source of carbon dioxide (CO2) emissions. Post-combustion capture through monoethanolamine-based absorption is viewed as the most mature technology proposed for mitigating ...
  • Study of power plant with carbon dioxide capture ability through modelling and simulation 
    Biliyok, Chechet (Cranfield University, 2013-11)
    With an increased urgency for global action towards climate change mitigation, this research was undertaken with the aim of evaluating post-combustion CO2 capture as an emission abatement strategy for gas-fired power ...
  • A study of trilateral flash cycles for low-grade waste heat recovery-to-power generation 
    Ajimotokan, Habeeb A. (Cranfield University, 2014-10)
    There has been renewed significance for innovative energy conversion technologies, particularly the heat recovery-to-power technologies for sustainable power generation from renewable energies and waste heat. This is due ...
  • A study on high-viscosity oil-water two-phase flow in horizontal pipes 
    Shi, Jing (Cranfield University, 2015-09)
    A study on high-viscosity oil-water flow in horizontal pipes has been conducted applying experimental, mechanism analysis and empirical modelling, and CFD simulation approaches. A horizontal 1 inch flow loop was modified ...
