Petrochemical industry is a strategic for nation because it has big impact on society at large. derivative products are an inseparable part of our modern life. With the development technology, humans can synthesize innumerable combinations petrochemical molecular structures to obtain materials with certain properties suitable final be made, from clothing, packaging, pharmaceutical, households, ...

This study adopts the centrifugal compressor system which produces the nitric acid equipment in China Petrochemical Development Corporation’s Plant. The system is non-linear and its manufacturing process is changeable, which the traditional PID (Proportional-Integral-Differential) control method is difficult to apply. This study is intended to apply the artificial neural network method to test ...

Spent petroleum catalyst from Korean petrochemical industry contains trace amount of metals such as Ni, V and Mo. Therefore an attempt was made to recover those trace metal using bioleaching process. Different leaching parameters such as Fe(II) concentration, pulp density, pH, temperature and particle size of spent catalyst particle were studied to evaluate their effects on the leaching efficie...

Greenhouse gases (GHG) emissions impose major threat to global warming potential (GWP). Unfortunately manufacturing sector is one of the major sources that contribute towards the rapid increase in greenhouse gases (GHG) emissions. In manufacturing sector electric power consumption is the major driver that influences CO2 emission. Titanium alloys are widely utilized in aerospace, automotive and ...

This essay introduces a new featured section, to be published in Small Axe annually, that explores the critical vocabulary of field Caribbean studies.

In the current environment, the economic clusterization, which contributes to closer interrelations between the businesses operating within this system and promotes development of the involved regions, represents one of the key factors relating to competitive ability improvement of the active businesses. Identification and assessment of regional clusters is actually regarded as an insufficientl...
