Enraf radar gauges for China petrochemical complex

Enraf has secured a major project investment for the CSPC Nanhai petrochemicals complex at Daya Bay in southern China, for 110 storage tanks employing 175 radar gauges

Enraf secures major project investment for the CSPC Nanhai petrochemicals complex at Daya Bay in southern China.

The project is the biggest ever single investment by a Shell chemicals company.

This massive USD 4.3bn complex has over 110 storage tanks employing 175 radar gauges.

Against stiff competition, Enraf will first be supplying the TDAS (Tank Data Acquisition System).

All field equipment will include 1mm accurate radar gauges, temperature and pressure interfaces.

These devices are designed to fit across the complete range of hazardous products stored at wide extremes of temperature and pressure.

CSPC will be employing the Enraf CIU Prime and Plus units, and Entis ProT software for the TDAS.

This combination offers the customer the functionality, availability and accuracy required on this high profile installation.

Through the use of fibre-optic networking and secure firewalls, Enraf have engineered an architecture that achieves complete fallback redundancy.

The integrated lightning and surge protection offered by the robust and proven Bi-Phase Mark communication links also more than satisfies the customer that this is a system which is going to offer maximum up-time and reliability.

The complex is centred around a naphtha cracker producing 800,000t/yr of ethylene.

In total the complex will produce some 2.3 million t/yr of product by 2005.

Located in the South Eastern corner of Guangdong province about 80 km from Hong Kong, Nanhai is part of a phased economic and industrial development plan for this coastal region.

In addition to providing a cornerstone for future regional growth, it will also make a significant contribution to reducing China's dependence on imported petrochemical products.

The partners in the project are Shell Nanhai, a member of the Royal Dutch Shell Group, and CNOOC Petrochemicals Investment Limited (CPIL).

Each company has a 50 percent stake in the project.

The joint venture, called CSPC, will build, own and operate the petrochemical complex as well as market material mainly to the domestic market.
