Calibrating three-hole probes before using them to obtain measurement data from turbomachines has become imperative. Calibration of the three-hole probe prior to its use in any turbomachinery measurement is crucial due to manufacturing inaccuracies during production. This study presents the calibration of a three hole probe used to measure the performance of a suction wind…

The maritime industry, a critical global trade facilitator, necessitates the movement of goods and passengers across the world’s oceans. Ships, the backbone of this industry, encounter diverse environmental conditions, from calm waters to tumultuous seas. Among these challenges, irregular sea conditions have gained increasing attention among naval architects, marine engineers, and safety regulators. The extremes…

In this work, the physico-chemical properties of Khana crude oil contaminated soils, are experimentally determined with respect to ASTM standard, as well the crude oil contaminated soils are remediated using Bacillus substilis and Aspergillus Niger. The kinetic parameters of the soils are as well ascertained using a well-developed biochemical model; estimating the concentration of the…

Breakdown of Floating Production, Storage, and Offloading systems (FPSOs) due to corrosion has been a major cause of downtime in FPSO operating in various regions. A major cause of corrosion in the FPSO is the radiation from jet flame of gas flare stack installed on FPSO. Although gas flaring on the FPSO is very resourceful…

An exergy and non-linear gas path analysis was carried out on a 180 MW gas turbine power plant in Afam, Rivers State, Nigeria. The plant major components were separated into control volumes of exergy inflows and outflows, then analyzing each flow using the first and second laws of thermodynamics. For non-linear gas path analysis, the…

This research presents a thermodynamic appraisal of a 112.5 MW Gas Turbine (GT) Plant through energetic and exergetic analyses utilizing the average operational data for ten (10) years. The components of the GT plant were simplified into control volumes and energy and exergy inflows and outflows, applying the first and second laws of thermodynamics, respectively….

It is common to find a less than 3% coating breakdown in the first 2 to 3 years of operation among FPSOs operating world-wide having hulls with conventional coatings (Cc). Two different coatings S1 and S2 formulated from an aggregate of paints shall be investigated along-side the conventional coating by means of factorial experiment, pull…

The aim of this study is to improve the performance of the propane refrigeration unit for precooling in a liquefied natural gas plant. Energy and exergy methods were used to analyze the performance of the unit. Aspen HYSYS v10 and Microsoft excel v2016 were used to carry out the simulation and analysis. Results obtained show…

This paper seeks to proffer an optimal power flow solution to the non-linear Euler-based load flow equations. Three Swarm intelligence (SI) optimization algorithms, namely, spider monkey (SM), artificial bee colony (ABC) and ant colony (AC) are used for optimal power flow diagnosis of the 330kV Nigerian transmission grid network. All algorithms are modeled and simulated…
