Kinetic Studies of Esterification of Rubber Seed Oil with Homogeneous Acid Catalyst for Biodiesel Production

Akhabue and Anor

Kinetic studies of the esterification of free fatty acid (FFA) of rubber seed oil (RSO) for biodiesel production was investigated in this work. Esterification of RSO was carried out in batch experiments using a 1 litre round bottom flask placed on a constant…

Comparison of Algebraic-KTGF and Transport-KTGF in Gas-Solid Flow Development in a Pilot-Scale Circulating Fluidised Bed (CFB) Reactor

Idris et al.

Numerical simulations of isothermal turbulent gas-solid flow in the riser of a pilot-scale circulating fluidised bed reactor has been carried out using FLUENT CFD software. An Eulerian-Eulerian multiphase flow model was used. The constitutive equations in…

Hydro-Cyclone De-oiler Enhancement for Produced Water Treatment

Appah and Aimikhe

This study investigated the effect of retrofitting and systematic upgrade of the Hydro- cyclone De-oiler unit during produced water treatment. The internal orifice of the oil reject cones attached to the end of the oil reject Liners was mechanically and…

Automatic First Break Picking from Pre-stack Seismic Section – Application in Sufyan Oil Field, Sudan

Eze and Mbachi

First break picking involves detecting the onset arrivals of refracted signals from a single signal source at the individual receiver in a receiver array. First-break picking can be done manually or automatically. This work outlines the procedures and…

Geological and Volumetric Risks Analysis of Hydrocarbon Reservoirs in‘‘Mgt’’ Field, Deep Offshore Niger Delta, Nigeria

Oladele et al.

The reservoirs in MGT field, deep offshore Niger Delta Basin Nigeria were studied with the aim of undertaking risk analysis of the identified prospects within the field through geological and volumetric assessments. Petrophysical analysis was carried out…

Correlations for Predicting Vapour – Solid Equilibrium Constants

Fiberesima et al.

The reliability of prediction models in determining hydrate forming temperatures adequately is of paramount importance. Most correlations have been found to vary significantly from experimental hydrate forming temperature data. This study is focused on…

Evaluation of Steady and Unsteady Flow Phenomena Using Computational Fluid Dynamics (CFD) Modelling Methodology in Circulating Fluidised Bed (CFB)/Fluid Catalytic Cracking (FCC) Reactor Systems.

Idris et al.

The simulation framework was developed from the licensed computational fluid dynamics (CFD15) software to simulate the hydrodynamics of gas-solid flow in CFB/FCC riser reactors. The predictions from the commercial CFD code (CFX and fluent) were based on the…

A Review of 3G Data on The Nigerian Benue Trough in View Of Renewed Hydrocarbon Exploration Campaigns

Obaje and Anor

The Nigerian National Petroleum Corporation (NNPC) has commenced another round of exploration campaigns for possible hydrocarbon deposits in the Nigerian Benue Trough. The Benue Trough, divided into lower, middle and upper portions, is a SW-NE trending…

Cross-Lingual Transfer in Low-Resource Morphological Tagging

We investigate cross-lingual transfer for morphological tagging in low-resource settings.
