3.8 PETROCHEMICAL INDUSTRIES 



3.8.1 Profile 



Petrochemical plants are major consumers of natural gas liquids and 

 refinery products, such as naphtha and gas oil. They convert these 

 "feedstocks" into several hundred intermediate and final products, 

 including ammonia, ethane, argon, hydrogen gas, fertilizers, neoprene 

 rubber, aromatics, and ethylene (Figure 6). Petrochemicals as a class 

 exclude fuels, such as gasoline, natural gas, kerosene, and coke, and 

 lubricating oil and similar directly consumable products. 



In general, petrochemical plants have a "refinery look" with their 

 typical mass of plumbing. They are highly visible industrial complexes
