This paper presents a method of sorption using peat for elimination of emergency spills of crude oil and petroleum products and the possibility of energy use of oil-saturated peat. The results of assessment of the sorbent capacity of peat are presented, with waste motor oil and diesel fuel chosen as petroleum products. Natural peat has been found to possess sorption properties in relation to petroleum products. The sorbent capacity of peat can be observed from the first minutes of contact with motor oil and diesel fuel, and significantly depends on their viscosity. For the evaluation of thermal properties of peat saturated with petroleum products, experimental studies have been conducted on determination of moisture and ash content of as-fired fuel. It is shown that adsorbed oil increases the moisture and ash content of peat in comparison with the initial sample. Therefore, when intended for energy use, peat saturated with petroleum products is to be subjected to additional drying. Simulation of net calorific value has been performed based on the calorific values of peat and petroleum products with different ratios of petroleum product content in peat and for a saturated peat sample. The obtained results are compared with those of experiments conducted in a calorimetric bomb and recalculated for net calorific value. A satisfactory discrepancy is obtained, which amounts to about 12%. Options have been considered providing for combustion of saturated peat as fuel (burnt per se and combined with a solid fuel) and processing it to produce liquid, gaseous and solid fuels. Peat can be used to solve environmental problems of elimination of emergency spills of crude oil and petroleum products and as an additional resource in solving the problem of finding affordable energy.

Despite the abundance of occurring natural crude oil resources, Nigeria continually suffers shortages of refined petroleum products, which undermines economic development of the country. The purpose of this multicase study was to explore the strategic role of how investment in petroleum refineries and infrastructures can improve supply and hence mitigate shortages or scarcity of refined petroleum products in the petroleum supply chain and enhance economic development in Nigeria. The research participants comprise of ten senior leaders from two private-sector Nigerian downstream petroleum supply companies located in the Niger Delta region, who had effectively implemented strategies for petroleum supply. The conceptual framework for the study was the resource based view theory. Data were collected through semistructured face-to-face interviews and review of operational and policy documents from the supply or marketing petroleum companies. Data were transcribed, analyzed, and validated through member checking and triangulation. The discoveries indicate the need to establish more refineries, privatize the existing moribund refineries, and build more infrastructures in Nigeria. Findings may be used by petroleum leaders and investors to optimize available crude oil natural resources, and to create investment strategies in the petroleum supply chain, leading to product availability, sustainability, poverty reduction, and economic development in Nigeria.

Abstract. Novianty R, Saryono, Awaluddin A, Pratiwi NW, Hidayah A, Juliantari E. 2021. The diversity of fungi consortium isolated from polluted soil for degrading petroleum hydrocarbon. Biodiversitas 22: 5077-5084. One of the major problems in the petroleum industry nowadays is crude oil spills. Riau Province, Sumatra is one of the largest oil producers in Indonesia. Accidental releases of petroleum products are of particular concern to the environment. The process of drilling and refining petroleum generates a large amount of oil sludge. One of the effective technologies used in the waste degradation process is bioremediation using certain microorganisms. The prime objective of the current research was to evaluate the efficiency of fungi consortiums in crude oil degradation in Bumi Siak Pusako-Pertamina Hulu, Indonesia. There are three potential fungi isolates as petroleum hydrocarbon degradation agents with four consortium variations. The parameter values of Optical Density (OD), pH, and diluted CO2 were measured on 0, 4, 8, and 16 days. To evaluate the fungal biodegradation activity using Gas Chromatography-Mass Spectrometry (GC-MS). The result showed that consortium II (KF II) has the highest potential to degrade petroleum hydrocarbon (50.61%). The visual GC-MS examination confirmed a decrease in the peak area for eight hydrocarbon compounds, indicating the efficiency of the fungi in the oil decomposition and dismantling of hydrocarbons. Our findings may provide new information on native fungal resources from chronically contaminated terrestrial environments, and will be useful for petroleum-contaminated bioremediation and other industrial applications.

Kaduna Refinery and Petroleum Company convert crude oil and other liquids into refined petroleum products. These petroleum products are used in our various homes as a source of energy but they can be a threat to human lives and the ecosystem. Gaseous emissions from the combustion of DPK of different volumes from Kaduna Refining were characterized for gaseous air pollutants using the E8500 combustion analyzer. The concentrations for the gaseous emission from the combustion of DPK were 34.92mg/m3 HC, 21.67mg/m3 CO, 89.00mg/m3 NOx for 10 ml. 41.47mg/m3 HC, 33.33mg/ m3 CO, 118.33mg/m3 NOx for 20 ml. 52.3 mg/m3 HC, 49.33mg/m3 CO, 183.33mg/m3 NOx for 30 ml. 50.20mg/m3 HC, 33.00mg/m3 CO, 189.33mg/m3 NOx for 40 ml. 61.12mg/m3 HC, 40.62mg/m3 CO, 199.00mg/m3 NOx , 2.6 mg/m3 SO2 for 50 ml. This study shows that CO and HC exceeded the acceptable limit for stationary sources while NOx and SO2 were below the acceptable limit. Hence, there is a need for rapid response and urgent attention from government and regulatory bodies to put in place policies that will help minimize the effect of these emissions.
