Some Geomechanical and Petrophysical Linkages Within Paleo-Sedimentary Beds of Ghana
Abstract: Instability issues have been a major challenge in the Sekondian Series of South-Western Ghana. This is particularly affecting civil works and environmental mitigation efforts across the formation as extensive weathered profile impedes structural integrity. Uniaxial Compressive Strength (UCS) of lithological units which is a critical stability measure in most engineering projects requires quality sample of appropriate dimension for its determination. Samples for this important design parameter cannot be easily obtained …

Investigation on Catalyst Selection for Polymerization Processes in Petrochemical Industries
Abstract: Organic polymers are long-chain compounds made of several repeating units. These polymers are either natural, such as protein, cellulose, starch or synthetic, such as polyethylene (a plastic), polyesters and polyamides (plastics and fibers) and polybutadiene (rubber).Many organic compounds possessing multiple bonds have the tendency to polymerize in the presence of an initiator. Polymerization of these compounds can either be affected by the use of chemical initiators such as free radicals …

A Review Paper on the Working of Petroleum Refineries
Abstract: ABSTRACT- What’s happen in petroleum refinery, why we have a tendency to install refineries and the way crude is refined, we will understand in simple means by this article. Crude can't be use directly, produce plenty of pollution and too much expensive also, therefore we'd like refined crude and establish several rock oil products like (kerosene/LPG/petrol/jet fuel/gas /naphtha etc.) for our desires for energy, heat and plenty of other’s needs. …
