Abstract:

Increasing production of gas via fracking technology in the United States has led to the re-emergence of the chemical industry in the US with several new chemical production facilities built in the gulf coast region. Many of these new production facilities include large multi-point ground flares (MPGF). Low-profile MPGFs are very efficient in processing large quantities of flare gas yet pose significant design challenges including elongated flames, high radiation flux to surrounding equipment and associated personnel safety. CFD tools have been used to analyze MPGFs having hundreds of flare burner tips surrounded by specially designed wind fences operated in a chemical plant. This presentation provides an overview of these flares and discusses recent analysis using a transient LES based CFD tool called C3d. This tool includes governing physics to describe soot formation, radiant flux, flame shape and height for an operating industrial scale MPGF. Previous model verification has been conducted for large pool fires and the code has validated for simulating flare performance by comparing measured flame height/shape and radiation flux to simulation results for single burner and three-burner tests when burning ethylene. Comparing transient predictions to steady state results illustrates the need to use transient analysis to capture flame dynamics and associated emissions production and radiation flux during operation of MPGFs in chemical plants. Using the right tool to correctly analyze these complex combustion systems is critical to safe and efficient operation of MPGFs to minimize environmental impact and reduce safety risks.

He has won about 20 national and international awards and his 600+ papers with ~130 co-workers have been cited more than 25,700 times for an H index of 81.

Abstract:

Solar water splitting (conversion of sunlight and H2O to H2 fuel and O2 or sunlight and H2O plus CO2 to fuel and O2) is a potential solution to our growing energy availability and environmental concerns. The huge international effort to produce “solar fuel” (artificial photosynthesis) is commensurate with the funding from governments for this research and its potential importance. Statement of the Problem: While we have solar electricity and this is now economically competitive with conventional electricity, we need fuel for many large-scale uses including ship and air transportation. Thus, there is a global effort to realize solar fuel. Solar fuel generation requires three unit operations, a water oxidation catalyst (WOC), generally viewed as the success-limiting factor, a light absorber-charge separator and a reduction (fuel formation) catalyst. We will describe the use of transition metal oxygen anion clusters (polyoxometalates or POMs), as H2 generation catalysts and more importantly, WOCs. After our initial papers on POM WOCs, many groups have made these molecular versions of metal oxide WOC films and conducted a range of mechanistic and other experiments. We will describe the new POM WOCs that work in acid and how WOCs can be interfaced with photo electrodes to generate H2 and O2. Mechanistic studies of the four-electron-transfer process to split water, the first of their kind, will be presented and the implications of this research discussed.

Session Introduction

Fasiu A Oluwole

University of Maiduguri, Nigeria

Title: Biodiesel yield of oil from four varieties of pre-treatment castor seeds (Ricinus Communist l)

Time : 11:50-12:20

Speaker
Biography:

Fasiu A Oluwole is a Senior Lecturer at the Department of Mechanical Engineering, University of Maiduguri, Maiduguri, Borno State, Nigeria. His research interest is on renewable energy with special interest in biofuels. He has built up this career after years of experience in research, evaluation, teaching and administration both in education institutions and development/fabrication of processing equipment. He has published more than 27 papers in reputed journals.

Abstract:

Statement of the Problem: The environmental effects (global warming) caused by the usage of fossil fuel and the environmental benefits of using renewable and environmental friendly energy resource has made biodiesel more attractive in recent times. Studies have been conducted on the transformation of castor oil into biodiesel. However, the varieties of castor oil used were not specified and little effort has been made to address the effects of oilseed pre-treatment methods on biodiesel yield and properties. This study therefore, investigates the production and characterization of biodiesel using oil expressed from four varieties of pre-treated castor seeds.
Methodology: Oil was expressed from each of the pre-treated castor seeds varieties using hydraulic press. The extracted oils were transesterified by reacting them with anhydrous methanol, using potassium hydroxide (KOH) as catalyst. The process parameters used were three levels of catalyst concentration, three levels of reaction temperature, three levels of reaction time, three heating methods and two seeds conditions. In all the experiments, a methanol/castor oil molar ratio of 6:1 was used. Biodiesel yield was calculated and the fuels obtained were characterized to determine the fuel properties.
Findings: A regression model was developed for biodiesel yield and response surface method (RSM) was used to confirm the polynomial equation solved using the Design-Expert 7.0 Software.
Conclusions: Highest biodiesel yield of 98.20% was obtained from raw dehulled GMS. Biodiesel yield varied with seed variety and was influenced by heating method, catalyst concentration, seed condition and their interactions. Biodiesel from oil of GMS variety possessed the best set of fuel properties and is therefore recommended for use in biodiesel production. The developed mathematical models adequately simulated the biodiesel production process and can be applied to the process involving oils of different origin.

Ifeyinwa Orakwe

Robert Gordon University, United Kingdom

Title: Integrated catalytic membrane reactor process for CO2 reforming of methane

Time : 12:20-12:50

Speaker
Biography:

Ifeyinwa Orakwe is currently undertaking her PhD programme at the Robert Gordon University, Aberdeen, United Kingdom. She is also a Research Assistant working on a project related to CO2 reforming of methane. She has a Bachelor degree in Chemistry and Masters in Environmental Science. In her research career, she has published in professional journal papers and made oral presentations at international conferences. Her research interests are in the areas of oil and gas, waste water and designing inorganic hybrid ceramic membrane for the purpose of water treatment and syngas production.

Abstract:

The greenhouse gases which are majorly CH4 and CO2 have raised concerns throughout the world due to their link to global warming and climate change. Research is ongoing to develop methods that can be applied commercially for the utilization of flue gases into useful products such as syngas. There are methods currently in use commercially such as the steam reforming and partial oxidation reforming for syngas production, but due to the requirement of very high operating temperatures, these methods are not usually economical for commercial syngas production. Recently, the use of membrane technology has drawn so much interest. In this study, a CO2 reforming method employing a catalytic membrane reactor process was built to study the CO2 reforming of methane. The membrane used was a tubular mesoporous tube consisting of Al2O3, with the rhodium catalyst impregnated into its pores by the wet impregnation method. The impregnation method allows for the catalyst to be deposited into the pores on the outer surface of the membrane. A flue gas stream comprising of CO2-12.5%, CH4-2.5%, CO-50ppm, N2-80.595%, O2-4.4% was feed into the reactor system as soon in figure 1 under various operating conditions: temperature range 700oC-900oC and flowrates of 0.45 and 1.50 Lmin-1. The exit stream was connected to a GCMS which was used to interpret the results. At 700oC, no conversions were realized but at 900oC, CO2 and CH4 conversions reached above 94%. Our catalytic membrane process is therefore a viable and effective technological breakthrough which converts the two most important greenhouse gases CH4 and CO2 into valuable syngas without the need for CO2 pre-separation from flue gas.

Yeshitila Asteraye Tsigie

National Taiwan University of Science and Technology, Taiwan

Title: In-situ biodiesel production from wet Chlorella vulgaris under subcritical conditions

Time : 14:00-14:30

Speaker
Biography:

Yeshitila Asteraye Tsigie has PhD in Applied Chemistry from National Taiwan University of Science and technology. He has his expertise in biofuels research. Biodiesel and bioethanol research have has been the focus of his research thematic area. He has conducted works on Biodiesel from yeasts and algae. Chlorella vulgaris was one of these microorganisms wherein the biodiesel research was undertaken.

Abstract:

The conventional base catalyzed biodiesel production process uses refined vegetable oil as feedstock oil and is not environmentally friendly. The supercritical methanol technology does not require the use of catalyst but it is energy intensive due to the high temperature and pressure required in the process. In this work, a process was developed for producing biodiesel directly from wet Chlorella vulgaris biomass (80% moisture content) using subcritical water as catalyst. Under the following conditions: The ratio of wet biomass to methanol is 1/4 (g/mL), the reaction temperature is 175 °C and after 4 h, the reaction product contained 89.71% fatty acid methyl esters (FAMEs). The yield is 0.29 g FAME per g dry biomass. This is considerably higher than the yield of 0.20g FAME per g dry biomass obtained when the neutral lipid of C. vulgaris biomass was extracted and converted into FAME.

Abstract:

In the search for eco-friendly carbon neutral and minimal pollutant emission generating fuels to combat global climate change in addition to issues of the energy security, biodiesel is at the front among the options available for potential bio-renewable fuels. The increasing interest in biodiesel and blends amongst production systems opens up new vistas of research from selection of appropriate raw materials and feed stocks to the desired end product quality and quantity. Biodiesel primarily obtained from the trans-esterification of the fatty acids or by pyrolysis/thermal cracking, however, to achieve the higher quality of biodiesel with higher conversion efficiency from the fatty acids demands exclusive optimum operational and solvent/reagents conditions in terms of their affordability and physico-chemical conditions. There are extensive efforts taken up on the optimization of feedstock oils but yet paradigm shift in the research can be visualized through the use of alternative efficient green solvents/ reagents/enzymes/catalysts and viable advanced low cost technologies. The measure of these qualities and performances after conversion are determined by prominent biodiesel parameters which may be chemo-physical, thermal, gaseous emissions, gravimetric/instrumental and engine performance. The utmost scope to work on the alternative green and sustainable energy is the addition to the use of modern nanotechnologies to biotechnologies for achieving the efficient process as well as optimum production parameters of biodiesel which complies with the US, European, South African and Indian biodiesel standards which are of essence. This paper explores these and their relationships in the biodiesel production systems and highlights their overall significance.
