The Nigerian Petroleum Industry Act (PIA) passed into Law in 2021 has the major goal to reform the Nigerian petroleum sector operations into policy, regulations and business (commercial). In the line of this, the Nigerian National Petroleum Corporation (NNPC) was transformed to NNPC Ltd to operate entirely commercially with a supervising Board and registration with the Corporate Affairs Commission. Such a commercial mandate will entail the need to explore and produce more oil and gas for export and domestic utilization. Oil is becoming less attractive as an energy source but gas is gaining momentum as a clean energy source in the global energy transition road-map. The global energy transition road-map is drawn around clean, alternative and renewable energies. The Nigerian frontier basins have recently come on board as new business opportunities with huge petroleum gas resources. These frontier basins comprise the Anambra, Benue, Bida, Chad (Nigerian sector), Dahomey, and Sokoto Basins as well as the Deep and Ultra-deep offshore. Maturing these basins through data generation and production of the gas resources therein will promote the nation’s gas utilization and gas expansion programmes meant to promote industrialization and huge employment generation, grow the economy and engender positive social transformation. The clause in the PIA that promotes frontier exploration is well-thought out. Available and required geological data needed to mature the frontier basins to producing basins are presented in this paper. The success made in Kolmani River-2 well discovery is a case study.

Albania, as a part of Western Balkan, has a variety of climate systems. This type of climate has a closed connection with waste treatment process. The biogas volume produced by the experimental environmental was 0.6 m3. The maximum methane concentration in biogas was reached at 55.8%/volume. The enclosed area (in oval circle) is another indicator of this system. This area extends over the period from 14.08.2018 until 26.08.2018 (12 days). The biomethane maximum biogas concentration reached 53.5 %/vol. up to 55.8% vol. The concentration drop was 4.2 %/vol. The main factor was the temperature. In the period of maximum durability the temperatures were minimum 30°C and maximum 42°C. Another contributing factor was the inoculum. Since inoculum was made from the treatment of four types of waste of different nature, then the concentration of microorganisms was higher. The purpose of the comparison between the two experiments is the sustainability of biogas production as well as the biomethane concentration biogas concentration on waste treatment. Environmental temperature was studied in three different regions of Albania: Shkodra, Tirana and Vlora. The observations showed that the region of Vlora has the longest period of average daily temperature (June 14th to October 1st).

This paper takes the high-power lithium battery as the research object. The battery capacity is 40Ah. The state of charge (SOC) of lithium cannot be measured directly. We establish an equivalent circuit model of the battery and use Matlab/Simulink to simulate the equivalent circuit model of the battery. The simulation results and analysis show that the designed control strategy can accurately estimate the SOC of the battery and provide a theoretical basis for the designed algorithm in the practical application of energy storage power stations.

Most of the fire accidents of exterior insulation in recent years started with the ignition of unprotected and exposed insulation materials. The fire spread on the thermal insulation layer will be affected by outdoor wind. In this paper, the influence of wind direction and wind speed on wall fire propagation characteristics was studied by carrying out medium sized experiments. The temperatures on the wall surface, radiation heat flux nearby, the infrared image and flame image were recorded during the tests with variation of wind direction and wind speed. It is found that with the increase of the angle between the wind direction and the wall, the surface temperature of the material, the radiation heat flux released decreases.This study results can provide valuable references for optimizing the fire safety design of exterior insulation layer.

The synthesis of C-H-O symbiosis network is considered in EIPs to reduce the amount of raw materials and waste discharge by using internal sources. In the conceptual design stage of C-H-O symbiosis networks, the concept of inherent safety index is introduced and safety factors are considered. Synthesis of C-H-O symbiosis networks based on i-safe index is proposed. Super-structure of C-H-O symbiosis networks was configured in EIPs, then optimization formulation was devised. A nonlinear programming (NLP) optimization model was established. A case study in Guizhou province shows that the method is useful in process decision-making, which could provide data support for early process decision making.

Abstract. In this work, the neutron flux distribution method to determine the effective multiplication coefficient keff has been numerical analysis by MCNP program. The neutron flux distribution of four multi-sphere system models are calculated, and the characteristic parameter c of each system are fitted with keff, so as to measure the keff of multi-sphere system. And experiment based on reactor system has been carried out to prove the method. Experiment results show that the keff obtained by the neutron flux distribution method are consistent with the experimental measurement results, indicating that the method is feasible and reliable.

The reaction of methanol synthesis via hydrogen and carbon dioxide which has a broad application prospect in the energy field should be carried out in a reasonable temperature range. Thus, a comprehensive thermal analysis under different work conditions for the reaction tube which is the really reaction place in the miniaturized methanol synthesis reactor is of great significance to its temperature control and thermal design. In this paper, the thermal analysis models of reaction tube in methanol synthesis reactor via hydrogen and carbon dioxide are established, through numerical simulation, the thermal performance results which include the molar ratio of methanol synthesis and temperature distribution inside reaction tubes changing with the reaction tube diameter, inlet gas temperature, and space velocity are obtained. Based on the results, the change laws of the methanol synthesis molar ratio and temperature distribution change with the three parameters are summed, which provide a reference to the thermal design and working conditions setting for the miniaturized methanol synthesis reactor of hydrogen and carbon dioxide.

Using Fengyun Medium Resolution Spectral Imager (FY3/MERSI) data from 2011 to 2018, this paper analyzed the characteristics of original spectra and the normalized difference vegetation index (NDVI) of lakes, reservoirs, rivers, paddy fields and swamps in Northeast China, A large-scale wetland extraction model was built using the decision tree classification method, and accuracy was verified in typical sites using China High-resolution Earth Observation System (CHEOS-1) data. The results showed that there were differences in the spectral curves and NDVI of different wetland types, especially the swamps, paddy fields and other landforms that showed a growth cycle with more significant differences in spectral curves and index curves than those of lakes, reservoirs and rivers. The total area of wetlands in Northeast China was 79,123.4 km2, including 5262.3 k m2 of lake and reservoir wetlands, 6514.7 km2 of river wetlands, 15284.7 k m2 of swamp wetlands and 52061.7 km2 of paddy fields. The accuracy verification showed that the area accuracy of wetlands was over 91.8%, the overall classification accuracy of wetlands was over 84.8% and the Kappa coefficient was over 0.6446.

In order to improve the execution rate of the power system dispatch plan, a dispatch plan assisted decision-making considering transient safety and stability constraints is proposed. First, the principles for formulating power system transient stability control scheduling are given. Then, through the topological analysis of the expected fault location, decouple the unstable faults, formulate appropriate multi-fault adjustment timing according to the severity of the fault, and decompose the prevention and control problems of multiple fault constraints into several single fault stable control decision problems. In the end, a preventive control adjustment strategy that satisfies all transient stability constraints is obtained. Combined with parallel computing technology, the algorithm has the feasibility of online application.
