Effect of Gas Flaring on Soil and Cassava Productivity in Ebedei, Ukwuani Local Government Area, Delta State, NigeriaJournal of Environmental Protection, 2013Co-Authors: Morrison Ifeanyi Atuma, Vincent Nduka OjehAbstract:
The threat to human, fauna and flora
life posed by pollution due to gas flaring cannot be over-emphasized. Gas
flared often resulted in some environmental degradation, one of such influence
is soil pollution and poor crop yield. This study examined the effect of gas
flaring on soil and cassava productivity in Ebedei, Ukwuani LGA, Delta State.
For the purpose of data collection, five (5) experimental sites were
systematically selected around the flare site in Ebedei and a control site at
Obiaruku. Soil samples were collected at
surface 0 – 10 cm and 10 – 20 cm at distance of 50 m, 100 m, 150 m, 200 m and 250 m apart respectively away from the
Bund Wall of the flare. The data generated were analysed using multiple
regression and paired t-test analyses. The study revealed that the soils found
in Ebedei have high composition of sand and soil temperature and are acidic.
The soil electrical conductivity, Phosphorous, Nitrogen, Potassium and Sodium
were very low. More so, the yield of cassava increases with a corresponding
increase in distances from flare site. The first hypothesis revealed that there
is significant variation in soil nutrients as distance increases from gas flare
sites. This is evident from F value of 234.99 which is greater than the
critical table value of 4.39. Furthermore, as flare distance increases, so also
the organic carbon, electrical conductivity and Nitrogen increase. The second hypothesis
revealed that there is a significant difference in cassava yield at gas-flared
area and the non-flared area which is evident at t (6.032) is greater than the
critical table (1.895) at P 0.05. It is
therefore recommended that Government and FEPA should enact environmental
Policies and revisit and review existing environmental and oil drilling laws in
Nigeria with a view of updating them to international and environmental
Sustainable Development and Gas Flaring Activities: a Case Study of Ebedei Area of Ukwuani LGA, Delta State, NigeriaResources and Environment, 2012Co-Authors: Vincent Nduka OjehAbstract:
The impact of gas flaring on the sustainable development was examined. The presence crude oil and natural gas is expected to serve as socio-economic driver of accelerated sustainable development of an area but the situation of oil producing areas of Nigeria is a far cry from the expected. Data was collected from eight (8) experimental sites around the gas flaring station including Obiaruku (control site), which has no gas-flaring station. Temperature and concentrations of air quality indices were determined. The temperature and air quality measurements in Ebedei were made, at least, 50 meters away from the Bund Wall of the flare. The data were analysed using the Multiple Regression and bivariate correlation. Results revealed that there is a significant relationship between ambient temperature and the gases (CO, NO2, SO4 and CH4) flared in Ebedei at F value of 20.069 which is greater than the critical value of 9.12. An increase in flared gases results to a corre- sponding increase in temperature. Strong negative relationship exists between distance from the Bund Wall of the flare and temperature at r=0.855. Recommendations: (FEPA) should constantly monitor and evaluate the level of damages done by gas flaring to ensure compliance and sustainability of the environment.

Safety Analysis of LNG Storage TankPetro-chemical Equipment, 2020Co-Authors: Tian Shao-weiAbstract:
At the development stage,LNG safe storage is very important.Based on the characteristics of LNG,various technical requirements of LNG for the safe storage was analyzed,such as Bund Wall,design pressure,material etc.Some suggestions for constructing of the single containment metal tank were given.

Discussion on Design of Bund Wall in LNG Tank Farm, 2020Co-Authors: Zhao ZhoumeAbstract:
The determination of effective volume and shape in design of Bund Wall in LNG tank farm as well as selection and proportion of concrete material are discussed with an engineering example. Suggestions for improving resistance of the Bund Wall to low temperature and high temperature are proposed.
