The use of inorganic binder for briquetting of subbituminous coal and torrefed biomass for energy generation is scarce. The present study focuses on the physicomechanical durability and energy content of briquettes produced from subbituminous coal (SubC) and torrefed biomass (TM) using bentonite as binder. Briquettes were produced using 95% SubC...

This work elucidates the effects of particle size and acid type on the yield of pectin extraction from waste orange peels powder and dry cake. The various acids considered in this work are hydrochloric, sulphuric and nitric acid. Three different particle sizes: 0.25nm, 0.15nm and 0.12nm corresponding to standard sieve BSS 60, BSS 100 and BSS 120 re...

A serious drop in ensuring the pipeline product quality in the distribution system is a factor that affects public health and wellbeing. The conventional methods of analyzing the Pipeline product quality require much time and labour. So there is a need to monitor and protect the pipeline product with a real time quality monitoring system to make ac...

Non-renewable diesel from fossil has been considered as potentially carcinogenic with serious harmful effect to human health and to the environment. This study aimed to produce a renewable diesel –biodiesel- via transesterification of waste cooking oil (WCO), investigated and determined the most suitable amongst various types of heterogenous cataly...

Curtailing the effects of environmental pollution being a major problem encountered by third-world countries, this study was embarked on to reduce the effect of land and water pollution caused by improper disposal of dye used by industries by using readily available agricultural waste like peanut Shell, bentonite clay and its composite. Analysis th...

Globally, there are two types of petroleum fiscal system; the concessionary and the contractual petroleum fiscal system. The main differences between the two types of petroleum fiscal system is the ownership of the resources and some distinct fiscal terms. The contractual petroleum fiscal system specifies a cost recovery option and profit oil split...

The development plan of the new oil field discovered in a remote offshore environment, Niger Delta, Nigeria was evaluated. As the oil in place is uncertain, a probabilistic approach was used to estimate the STOOIP using the low, mid, and high cases. The STOOIP for these cases were 95 MMSTB, 145 MMSTB and 300 MMSTB which are the potential amount of...

The nature of oil and gas Nation's petroleum fiscal system affects the survival of exploration and production (E&P) companies during periods of low oil price as these companies are expected to pay royalty to the government irrespective of the price of oil. This affects the sustainability of E&P companies during periods of low oil price. There is th...

The petroleum industry bill (PIB) in Nigeria aims to reform the petroleum sector of the country and increase government revenue from petroleum investments. Despite the benefits the bill offers to the country, its passage has suffered several setbacks. This research therefore studied the impact of the delay in passing the bill on deep offshore inves...

Nigeria recently amended the Deep Offshore and Inland Basins Act. The Act seeks to generate aditional annual revenue of over $1 billion for the government. The 2019 Law seems attractive to the government in the short run in terms of early rent extraction; on one hand, the seeminglly attractiveness of the fiscal terms in the Ammended Act, which is t...

Drilling additives play a unique role during drilling operations, from aiding in the control of various drilling challenges to successfully enhancing downhole drilling efficiency. pH enhancers are amongst the plethora of additives imported into Nigeria at exorbitant prices to aid in drilling operations. These additives includes NaOH, Na 2 CO 3 , Ca...

With the explosive increase in the data traffic of wireless communication systems and the scarcity of spectrum, terahertz (THz) frequency band is predicted as a hopeful contender to shore up ultra-broadband for the forthcoming beyond fifth generation (5G) communication system. THz frequency band is a bridge between millimeter wave (mmWave) and opti...

The general success ratio of wells drilled lies at 1:4, which highlights the difficulty in properly ascertaining sweetspots. well placement location selection is one of the most important processes to ensure optimal recovery of hydrocarbons. Conventionally, a subjective decision is based on the visualization of the HUPHISO (a product of net-to-gros...

An agricultural residue, white yam (Dioscorea rotundata) tuber peel (YTBS), was used for the removal of Cd(II) ion from an aqueous solution using a batch method. The adsorbent was characterized using FTIR, TGA, SEM, EDX, N2 BET, XRD, and XRF. The optimization of sorption variables such as pH, contact time, adsorbent dose, and initial metal ion conc...

In this study, cadmium and lead ions removal from aqueous solutions using a commercial activated carbon adsorbent (CGAC) were investigated under batch conditions. The adsorbent was observed to have a coarse surface with crevices, high resistance to attrition, high surface area and pore volume with bimodal pore size distribution which indicates that...
