The objective of the study focuses on gas/non-Newtonian liquid horizontal flow in a pipeline. The gas and the liquid flow rates were varied over a wide range of flow conditions. The flow rate of the non-Newtonian liquid ranged from 0.023 to 0.115 m3/s, while that of the gas ranged from 0.023 to 0.160 m3/. The experiment was conducted to determine the pressure drop using a transparent pipe of 76.2 mm diameter and 2.44 m long horizontal pipe. Xanthan gum solution was used to simulate non-Newtonian fluid. The pressure drop gradient model of Lockhart-Martinelli as modified for gas/shear thinning fluid flow. The theoretical predictions of pressure loss were compared with the experimental data for air/shear thinning fluid flow results. From the experimental work, it was observed that the pressure drop was directly proportional with the concentration of Xanthan gum (shear thinning fluid). The flow regimes of bubbly, slug, plug and wavy flow were also captured by a high-speed camera.

Mesfin is currently working as Assistant Professor & Program Director of Chemical Engineering at Heriot-Watt University Dubai Campus. He was a postdoc fellow at Yeungnam Univeristy (South Korea) before joining Curtin University, Sarawak Malays as faculty staff. Mesfin has won the 2014 IChemE Malaysia Award for Research Innovation and Excellence. He also got a prize for his research being highly commended in the Petrochemical Processing Award at the 2013 IChemE Malaysia Awards for Innovation and Excellence”. He has won also the 2015 APAC-EMEA (Asia Pacific, Europe, Middle East & Africa) Honeywell UniSim Design Challenge & the 2014 Asia Pacific Honeywell UniSim Design Challenge. His current research work focuses on optimal design and operation of thermally coupled distillation unit under uncertainties. Thermally coupled distillation such as dividing wall column (DWC) has significant advantage in terms of energy saving by more than 30% compared to the conventional distillation columns.


Uncertainty is an inherent characteristic of any process. It may arise both from external and internal factors and has a profound effect especially for gas processing plant as its feeds are normally originated from upstream production facilities. Thus, the plant is usually subjected to continuous variations in upstream conditions, such as feed flow rate, composition, ambient temperature and pipeline pressure. These variations effects propagate throughout the plant and affect its normal operation. As a result, decision making for optimal operating conditions of an in-operating plant is a complex problem and it is exacerbated with changing product specifications and utility requirements. Moreover, the condition of feed composition is an important factor since it mainly determines what kind of process configuration to be employed for recovering natural gas liquids (NGLs). Besides, due to the number of process schemes developed for NGL recovery, it is usually difficult to select the best process scheme that can consolidate capital and operating costs within an acceptable range. In industrial practice, heuristic optimization approach based on trial and error have been employed to solve those problems. The main reason for such kind of decision is due to lack of systematic solution approach. As a result, aggressive decision may be preferred due to high profit expectation. However, this strategy will deteriorate the objective function and later leads to constraint violation. Therefore, a systematic method is required to evaluate the trade-off between profitability and reliability of holding the process constraints. The challenge here is how to find solution approaches that can incorporate all these uncertainties effect and enable us to make prior-decision for the in-operating plant.

The adoption of any petroleum arrangement - concessionary or contractual - is a financial issue that is centered on how costs are recovered and profits divided, which is at the heart of taxation and economic rent theories. Hence countries are expected to make the tax system attractive for the IOCs in order to encourage inward investment. The effectiveness of any petroleum arrangement depends largely on the attractiveness of its underlying tax regime which, in turn, depends on the effectiveness of its design and implementation. The uncertainty created by the non-passage of the proposed Nigeria Petroleum Industry Bill (PIB) over the years has continued to impede investments in the oil and gas sector in Nigeria. Oil producers Trade Section (OPTS) and other stakeholders in the sector in Nigeria have expressed concerns over the federal government’s intention to change the laws governing the oil and gas industry including the fiscal terms. The aim of the study is to critically examine whether the Nigerian petroleum tax system is appropriately designed and effectively implemented to achieve the benefits the country desires from its petroleum taxation arrangements. The study reviews the current and post PIB upstream fiscal regimes and undertook a comparative examination of Nigeria’s fiscal regime against selected world fiscal arrangements. The study also determined how Nigeria’s fiscal regime holds up against key features of importance to government and prospective investors, which include degree of stability, flexibility, neutrality and how the regime distributes the burden of risk between the resource owner and the oil companies. The study concluded from preliminary studies that there is a correlation between fiscal terms (tax and royalty) and various profitability indexes (DCFR, PIR, AVP, PVP, MCI & payout). The global comparative analysis result also shows that Nigeria fiscal terms (pre & post PIB) are outside the competitive window and will invariably discourage foreign direct investments.

Among OECD countries, Turkey has the highest rate of increase in energy demand since 2010, and it is noteworthy that it depends on energy imports to a large extent. The continuation of the decline in oil prices in 2015 has enabled Turkey to reduce its oil and natural gas import costs as well as other oil and natural gas importing countries. The crude oil supply of Turkey in 2014 is shown in Figure 1.

In 2015, Turkey produced approximately 51 thousand v/d crude oil per day. Whereas, 796 thousand v/d crude oil was consumed; import of crude oil at 503 thousand v/d level and 242 thousand v/d imports of finished goods were realized. Compared with the year 2014, while imports of finished products showed a decline, crude oil imports and crude oil consumption increased. In 2015, the total consumption rate of domestic crude oil production was 6.4%. The consumption rate of Turkey’s domestic natural gas production in 2015 was the lowest in the last decade and realized as 0.8%. In other words, Turkey's import dependency rate for petroleum is 93.6%, and natural gas import dependency rate is 99.2%. In 2015, the distribution of petroleum imported by Turkey according to the source countries has changed considerably compared to the year 2014. It is observed that in 2014, 90% of the imports are made in only six countries, while in 2015 the source country balances have changed. Iraq ranks first with 29%, Russia second with 18%, Iran third with 14%. Compared to 2014, the rate of oil imports from Iran and Saudi Arabia has fallen, while the share of Russia and India has risen considerably. When we look at the source countries where oil is imported in 2015, the most noteworthy point is the diversity of countries where oil is imported at low levels.
