Day 1 :
University of Bergen, Norway
Time : 09:30-10:05
Bjørn Kvamme obtained his MSc in Chemical Engineering (1981) and PhD in Chemical Engineering (1984) from the Norwegian University of Technology and Natural Sciences. After a short period with SINTEF and two years at Bergen University College, he was appointed to full Professor in 1987 and started education of MSc and PhD in Process Technology in Telemark. He entered a position as Professor in Gas Processing at Department of Physics, University of Bergen in March 2000. He is the author/co-author of 373 publications, of which 140 are in high quality journals.
Hydrocarbons being transported in pipelines will always contain some dissolved water. High pressures and low temperature involves a risk of hydrate (ice-like crystals contain up to 14% CH4) formation. The traditional way to calculate the risk of hydrate formation and the corresponding level of water content that can be permitted before transport has been to calculate water dew-point and the checking if presence of liquid water would lead to hydrate formation at the conditions of temperatures and pressures at these conditions. Pipelines being used for hydrocarbon are, however, normally covered by rust even before they are placed out. One of the most stable iron oxide in rust is Fe2O3. This mineral is a very good adsorption material for water and will as such represent another route for the water to drop out from hydrocarbon mixtures. The chemical potential of water adsorbed on rust can be 3.4 kJ/mole lower than chemical potential of liquid water at relevant conditions. In this study we have examined maximum water content which can be permitted in mixtures of CH4 and C2H6 when considering adsorption drop out versus drop out as liquid water. For CH4 contacting water the tolerance limit based on liquid water drop out is found to be in the order of 26 times higher than corresponding limit based on rust adsorption, for temperature 275 K and pressures between 50 and 250 bars. Similar ratios are also found for pure C2H6 and a mixture of CH4 with 20% C2H6. As a consequence the hydrate risk analysis needs to be revised in order to reflect the most preferred routes for water drop out from gas.

Emergency oil spills during transportation of them by water way, from offshore oil drilling rigs and other sources can rapidly result in harm to the ecosystem and leads to negative and social impact. The development of effective methods on oil spill elimination is a task of singular importance. Burning can be used where other methods are not effective spill response, and can be done in parallel with other methods of spill after determining an appropriate method for a particular site or geographic region. The paper provides an overview of the current state of the problem, and research results on combustion of Karazhanbas and Tengiz oil on water surface were carried out. It has been established that minimum thickness of oil blanket, allowing to initiate and support combustion process, lie in the range of 3-5 mm. For ignition and maintenance of stable combustion of oil on water surface, the synthetic sorbent was suggested. It is found that, the synthetic sorbent accelerates the combustion process of oil on water surface threefold in comparison with combustion process of oil without sorbent. It is shown that the remaining mass of oil on water surface after combustion process termination, presents the bitumen substance, having a good adherence and strong adhesion that allows taking it with high efficiency by mechanical method.
Indian Institute of Technology-Bombay, India
Time : 10:40-11:15
Akkihebbal K Suresh completed his PhD from Monash University. After a brief stint with Hindustan Lever Research Centre (a Unilever company), he joined the Indian Institute of Technology Bombay in 1988 and has been with the Institute ever since. He currently holds an Institute Chair in the Department of Chemical Engineering. He served as the Head of the department from 2005-2008, and as the Dean of Faculty Affairs of IIT Bombay during 2009-2014. Apart from an abiding interest in liquid phase hydrocarbon oxidations, his work encompasses other themes in transport and reaction engineering. He is a Fellow of the Indian National Academy of Engineering.
There are many processes in the general petrochemicals and petroleum processing arena which are characterized by a complex network of reactions, and hence a complex reaction mixture which presents challenges for product workup. While in principle, catalysis presents a possible solution to reduce the complexity of such reactions via a selective promotion of the desired steps in the network, development of appropriate catalysts remains very much an art to this day, if one that is informed by a wealth of experience and some theoretical developments. In this task, we shall discuss some case studies from the petrochemicals and related areas such as biodiesel and automotive catalysis, to illustrate both the possibilities as well as the challenges. Each case study illustrates a separate set of issues. Among the challenges illustrated will be (a) that of selectivity (b) the role of catalyst support (c) synergistic behaviour when catalysts are combined, (d) catalyst activation and deactivation.
