GENERAL SITUATION The petrochemical industry is a technology and capital-intensive industry. The United States took the lead in the development of the petrochemical industry and started launching petrochemical projects in the 1930s and 1940s. The petrochemical industry in other developed countries, such as Germany, the United kingdom, France, Italy and Japan, began their development in the 1960s and 1970s.The petrochemical industry in these countries has played展开更多
