China is among a number of large developing country or new powers on the ascendance in the international system, all of which are deepening their economic relations with Africa However, China is the largest and most powerful of this group. it has sought closer economic relationships with other developing country regions and continents such as Latin America and Central Asia, but it is with Africa - the continent that hosts more developing countries than any other - that China has fostered the closest links.This book provides an overview of how the China - Africa relationship has evolv |

Sommario/riassunto |
|
A modern reference to the principles, operation, and applications of the most important compressor typesThoroughly addressing process-related information and a wider variety of the major compressor types of interest to process plants, Compressors and Modern Process Applications uniquely covers the systematic linkage of fluid processing machinery to the processes they serve.This book is a highly practical resource for professionals responsible for purchasing, servicing, or operating compressors. It describes the main features of over 300 petrochemical and refining schematics |
