In the modern petrochemical industry, naphtha is hailed as a vital bridge connecting refining and chemical sectors. As the core feedstock for ethylene, propylene and a wide range of basic petrochemicals, naphtha occupies a pivotal position in the global petrochemical industrial chain.
As one of China’s leading integrated refining and chemical enterprises, Zhenhai Refining & Chemical Company leverages advanced refining facilities, a complete petrochemical industrial chain and consistent technological innovation to continuously boost the comprehensive utilization efficiency of naphtha resources, delivering solid support for the development of China’s and even the world’s chemical industry.
Naphtha is a light distillate obtained from crude oil distillation, with a typical boiling point range of 30°C to 200°C.
Classified by application, naphtha falls into two main categories:
Naphtha can be used both as a gasoline blending component and a critical feedstock for the petrochemical sector.
Within petrochemical production, naphtha fed into steam cracking units yields the following fundamental chemical building blocks:
These primary raw materials are further processed into plastics, synthetic rubber, chemical fibers and diverse high-end specialty chemicals.
Located in Ningbo, Zhejiang Province, Zhenhai Refining & Chemical ranks among China’s largest integrated refining and chemical complexes.
Supported by large-scale refining installations and complete auxiliary chemical facilities, the company has built a full-length naphtha value chain: Crude Oil → Refining Processing → Naphtha → Ethylene Cracking → Basic Petrochemical Feedstocks → High-End Chemical Products
This integrated refining-chemical model maximizes the value extracted from naphtha and lifts overall industrial chain profitability.
Compared with conventional standalone refineries, integrated operations not only raise feedstock utilization rates but also strengthen the company’s resilience against market volatility.
Naphtha cracking serves as a foundational process for modern petrochemical manufacturing.
During high-temperature steam cracking, naphtha is converted into large volumes of high-value olefin products, among which ethylene and propylene are the two most essential base chemicals.
These derivatives are widely deployed in the following downstream segments:
Used for packaging materials, agricultural films, pipeline systems and consumer goods manufacturing.
Extensively applied in automotive parts, home appliances, medical supplies and textile industries.
Supplies raw materials for tires, industrial rubber goods and automotive components.
Supports the production of polyester, engineering plastics and functional specialty chemicals.
With continuous expansion of Zhenhai’s ethylene projects, its naphtha cracking capacity keeps growing, delivering more stable feedstock supply to downstream manufacturers.
Global petrochemical demand for naphtha has maintained an upward trend in recent years, driven mainly by:
Particularly across Asia, continuous capacity expansion of ethylene and polyolefin plants has further elevated naphtha’s importance as a primary cracking feedstock.
Benefiting from superior geographic location and production scale, Zhenhai Refining & Chemical has evolved into a major hub for naphtha processing and utilization in eastern China.
Against the backdrop of global energy transition, Zhenhai Refining & Chemical actively advances digital transformation and green low-carbon development.
Through smart factory construction, the enterprise achieves:
Meanwhile, the company consistently deploys energy-saving and emission-reduction technologies to improve naphtha processing efficiency and cut energy use and carbon emissions per unit of output.
Green manufacturing and efficient resource utilization have become core development priorities for modern refining and chemical enterprises.
Despite the rapid growth of new energy sources, naphtha will remain a vital feedstock for the global petrochemical industry over the coming decades.
As demand surges for high-performance polymers, new energy materials and functional chemicals, naphtha’s strategic value will become even more prominent.
For Zhenhai Refining & Chemical, continuously optimizing deep processing capacity of naphtha and increasing the share of high value-added products will act as a core pathway driving the company’s high-quality development.
Via refining-chemical integration, digitalized operation and innovative low-carbon technologies, Zhenhai Refining & Chemical is steadily strengthening its competitive edge within the global petrochemical value chain.
Naphtha is an indispensable fundamental feedstock for modern petrochemical manufacturing, and Zhenhai Refining & Chemical stands as a leading Chinese enterprise specializing in naphtha deep processing and comprehensive resource utilization. Supported by a mature integrated refining-chemical layout and persistent technological innovation, Zhenhai not only unlocks greater value from naphtha resources but also provides solid raw material backing for the growth of polyolefin, advanced new material and high-end chemical sectors.
Looking ahead amid ongoing global chemical market upgrading, Zhenhai Refining & Chemical will play an increasingly critical role in naphtha value chain optimization and the development of premium chemical products.
