Optimization and utilization of ethylene raw material in integrated petrified enterprise;

In the purchasing of crude oil, it can select appropriate kind of crude oil to take place the planned variety according to the change of market Moreover, it can be used to calculate the profit of petroleum refining and chemical enterprises, as well as the sulfur distribution in each plant and product according .

Selection and implementation of auto-control systems in petrochemical enterprise;

Petrochemical enterprises in China are facing strong impact from international powerful counterparts after China has become a member of WTO.

Using a large-scale refining-chemical integrated enterprise with 8 million t/a crude processing capacity as an example, raw materials for ethylene were optimally arranged from many angles, including refining-chemical integration , choice of crude oil, choice of wax oil and heavy oil processing schemes and long-term operation of unit, commercial operation result achieved anticipated goal.

It also introduces the experience of integration of oil refining and chemical industry with Reliance Industries Limited(India) refining-chemical integration project, CNOOC Nanhai Petrochemical 12 million t/a refining project and CNOOC-Shell Petrochemical 800 kt/a ethylene project as examples.

To introduce three new technologies of refinery-chemical integration in brief, bring forward a ethylene developing case of advanced refinery-chemical integration, in which ethylene feedstock is higher and lighter quality, and the propylene to ethylene ratio is above 1.

The features of Lean Production in shipbuilding are to implement the product flexible manufacturing on Enterprise Wide Integration,to coordinate supply chain,to integrate CAD/CAPP/CAM and to employ advanced shipbuilding technology.
