  • Metering practice and policy : an examination of battery electromagnetic meter calibration, performance and verification 
    Thomas, Alun Lewis (Cranfield University, 2009-09)
    The last twenty years has seen the rise to dominance of electromagnetic flowmetering (EFM)technology within the UK water industry network. In the last ten years, the introduction of battery powered EFM designs, for both ...
  • Modelling of an axial flow compact separator using neural network 
    Qazi, Nadeem (Cranfield University, 2009-05)
    A novel design axial flow cyclonic separator called I-SEP was tested with an extensive set of experiments using air-water two phase flow mixture at atmospheric pressure. These experiments provided valuable data on the ...
  • Modelling of transient gas-liquid flow and pigging in pipes 
    Lima, P. C. R. (Cranfield University, 1999-08)
    More and more transient gas-liquid operations in pipes are being successfully applied in the oil and gas industry. Pigging in two-phase pipelines, to remove liquid accumulation or for cleaning purposes, is an important ...
  • Modelling the two-phase performance of a centrifugal pump 
    Downham, S. E. (Cranfield University, 2000-03)
    A review was carried out which revealed that no simple mathematical model was available which could be used to predict the performance of a centrifugal pump when it is operating under two phase flow conditions. Experimental ...
  • Multiphase characteristics of high viscosity oil 
    Al-Awadi, Hameed (2011-11)
    Heavy oil production has drawn more and more attention in petroleum industry. The amount of heavy oil in the world is twice more than the conventional oil (low viscosity), which has been consumed rapidly from the past. ...
  • Multiphase flow measurement using gamma-based techniques 
    Arubi, Isaac Marcus Tesi (Cranfield University, 2011-03)
    The oil and gas industry need for high performing and low cost multiphase meters is ever more justified given the rapid depletion of conventional oil reserves. This has led oil companies to develop smaller/marginal fields ...
  • 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 ...
