  • Active control of hydrodynamic slug flow 
    Inyiama, Fidelis Chidozie (Cranfield University, 2013-04)
    Multiphase flow is associated with concurrent flow of more than one phase (gas-liquid, liquid-solid, or gas-liquid-solid) in a conduit. The simultaneous flow of these phases in a flow line, may initiate a slug flow in the ...
  • Design and analysis of robust controllers for directional drilling tools 
    Ghole, Amaan (Cranfield University, 2016-08)
    Directional drilling is a very important tool for the development of oil and gas deposits. Attitude control which enables directional drilling for the efficient placement of the directional drilling tools in petroleum ...
  • Experimental and simulation studies on performance of a compact gas/liquid separation system 
    Zhou, Ying Hui (Cranfield University, 2013-01)
    The need of exploiting the offshore oil reserves and reducing the equipment costs becomes the motivation for developing new compact separation techniques. In the past years, the development of compact separators has ...
  • Multiphase flow instability and active slug control solutions 
    Tandoh, Henry Kwaw Ayisi (2018-03)
    Slugging as a flow assurance challenge is an upsetting condition to the oil and gas industry due to the instabilities it poses on the system. The negative repercussions associated with slug flow stems from the inlet through ...
  • Multiphase severe slug flow control 
    Ogazi, Anayo Isaac (Cranfield University, 2011-01)
    Severe slug flow is one of the most undesired multiphase flow regimes, due to the associated instability, which imposes major challenges to flow assurance in the oil and gas industry. This thesis presents a comprehensive ...
  • Nonlinear dynamic process monitoring using kernel methods 
    Samuel, Raphael Tari (Cranfield University, 2016-08)
    The application of kernel methods in process monitoring is well established. How- ever, there is need to extend existing techniques using novel implementation strate- gies in order to improve process monitoring performance. ...
  • Nonlinear model predictive control using automatic differentiation 
    Al Seyab, Rihab Khalid Shakir (Cranfield University, 2006)
    Although nonlinear model predictive control (NMPC) might be the best choice for a nonlinear plant, it is still not widely used. This is mainly due to the computational burden associated with solving online a set of ...
  • Optimal Design and Operation of Heat Exchanger Network 
    Salihu, Adamu Girei (Cranfield University, 2015-08)
    Heat exchanger networks (HENs) are the backbone of heat integration due to their ability in energy and environmental managements. This thesis deals with two issues on HENs. The first concerns with designing of economically ...
  • Optimization of Reservoir Waterflooding 
    Grema, Alhaji Shehu (Cranfield University, 2014-10)
    Waterflooding is a common type of oil recovery techniques where water is pumped into the reservoir for increased productivity. Reservoir states change with time, as such, different injection and production settings will ...
  • Petroleum refinery scheduling with consideration for uncertainty 
    Hamisu, Aminu Alhaji (Cranfield University, 2015-07)
    Scheduling refinery operation promises a big cut in logistics cost, maximizes efficiency, organizes allocation of material and resources, and ensures that production meets targets set by planning team. Obtaining accurate ...
  • Predictive condition monitoring of industrial systems for improved maintenance and operation 
    Ruiz Cárcel, Cristóbal (Cranfield University, 2014-07)
    Maintenance strategies based on condition monitoring of the different machines and devices in an industrial process can minimize downtime, increase the safety of plant operations and help in the process of decision-taking ...
  • Stabilising slug flow at large valve opening using an intermittent absorber 
    Ehinmowo, Adegboyega Bolu (Cranfield University, 2015-07)
    Slugging is one of the challenges usually encountered in multiphase transportation of oil and gas. It is an intermittent flow of liquid and gas which manifests in pressure and flow fluctuations capable of causing upset in ...
  • Studies on non-linear dynamic process monitoring 
    Iketubosin, P. P. (Cranfield University, 2011-07)
    Owing to the numerous benefits of process monitoring, the subject has attracted a lot of attention in the last two decades. Process monitoring is an art of identifying abnormal deviations in a process from the normal ...
