Pressure transient analysis of multiple leakages in a natural gas pipeline

Pipelines are principal devices for natural gas transportation which are amenable to operational challenges such as leakages. Several methods for predicting leakages in natural gas pipeline have been developed. Some of these techniques detect leakages after several hours while some are prone to false alarms or inaccurate predictions. This study developed a pressure transient analysis model for predicting gas pipeline...

A study of the effects of waste lubricating oil on the physical/ chemical properties of soil and the possible remedies

Waste oil management in Nigeria is not well supervised, hence the indiscriminate disposition into the soil drains and sometimes open water. This has attendant implications on soil and water quality. Need has arisen to evaluate the consequence of such mismanagement on the environment. This study was designed to evaluate the effects of waste oil on the physical and chemical properties of soil in Lagos, and the possible...
