Huajin Ami 73.6/700000 Tons/Year Ethylbenzene/Styrene Plant Officially Centered, Liaoning Large Styrene Production Capacity Enters Countdown to Production

On July 2, 2026, the 73.6/700000-ton/year ethylbenzene/styrene plant of China Huajin Ami Fine Chemical and Raw Material Engineering Project held a mid-shift ceremony. The construction task of the main project was fully completed and officially transferred from the construction stage to the production preparation stage. The landing of this node marks the official countdown to production of a set of heavyweight styrene production capacity in Liaoning, China.

Construction history: 8 months of steady progress, a full set of verification procedures completed.

This set of equipment from mechanical completion to the delivery of about 8 months, the key nodes in order to advance, the construction rhythm is stable and orderly. On November 15, 2025, the plant machinery will be completed, the main works of civil engineering, equipment and process pipelines will be completed, and the stage of three checks and four decisions, purging and pressure test and linkage test run will be transferred. January 2026 35KV 1# and 2# main transformers were successfully powered once, and the power system of the plant was officially started. On June 1, 2026, the safe production month will start, and special operations for hidden danger investigation and emergency drills will be deployed to enter the safe sprint before production; on July 2, 2026, the device was officially handed over and entered the production preparation stage.

Within the 8-month construction verification period, a complete set of procedures such as electrical power receiving, system pressure test and linkage test run were completed, laying a solid foundation for the success of the subsequent start-up.

Technical Highlights: Badger process blessing, large-scale main device construction difficulty is high

this device adopts the advanced technology of Badger Company in the United States, and is a representative large-scale main device in the same industry. Badger ethylbenzene/styrene process has a wide range of industrial applications in the world, with high selective catalytic dehydrogenation technology is known, product purity and yield are in the industry leading level.

At the construction level, the scale of the device is large, the equipment precision is high, and the requirements for the installation of process pipelines and the medium construction precision of the equipment are extremely harsh. Civil engineering, structure, equipment, instrumentation, electrical and other multi-disciplinary highly cross-operation is difficult to coordinate the project, which is one of the core devices with high construction difficulty in the whole Huajin Amei project. CCCC success itself is an important verification of the construction management ability of the construction team.

Industry impact: three dimensions to analyze the market impact of 700000 tons of styrene new capacity.

Huajin Aramco is backed by Saudi Aramco's capital and raw material advantages, 700000 tons/year styrene belongs to China's domestic single set of large-scale device magnitude, once the formal production will be from the supply, raw materials, downstream three dimensions of the market pattern has a significant impact.

On the supply side, 700000 tons of new production capacity will form a direct supplement to the spot market of styrene in North China and Northeast China. However, what needs to be clearly understood is that China's domestic styrene is already under the pressure of overcapacity, and the new capacity will further suppress the regional price center. For existing styrene suppliers and traders, the downward pressure on styrene prices in North China and Northeast China needs to be included in the evaluation of pricing and inventory strategies in advance.

At the raw material end, the 736000-ton/year ethylbenzene unit is used as a supporting upstream, relying on the self-supply of pure benzene and ethylene raw materials to build a complete "pure benzene + ethylene & rarr; ethylbenzene & rarr; styrene" integrated chain. The advantage of self-supply of raw materials will give Huajin Ami significant cost competitiveness, and its profitability will be significantly better than that of competitors relying on outsourced ethylbenzene in the downward cycle of styrene prices, which constitutes a continuous cost suppression for small and medium-sized styrene producers in the region.

In terms of downstream conduction, styrene is the core monomer of many important downstream products such as ABS, EPS, PS, etc. After the release of Huajin Amei's production capacity, the raw material procurement costs of ABS, EPS and PS production enterprises are expected to benefit from abundant regional supply. However, traders need to be alert to the downward risk of styrene spot price brought about by the increase in supply, and pay special attention to the change of regional price difference between North and East China to avoid accumulating excessive spot exposure in the downward price channel.

Combined with the recent dynamics of China Jinxi Petrochemical's 800000 tons/year aromatics transformation to produce qualified pure benzene, the systematic expansion trend of aromatics and styrene industry chain in Liaoning is clearly visible. Overlay BASF Guangdong base, CNOOC Shell Phase III and other large-scale ethylene projects in South China, China's styrene national production capacity pattern will usher in a deep restructuring between 2026 and 2027.

Follow-up Key Observation Nodes

the current device has completed the delivery and entered the production preparation stage, the next key signal is the commissioning announcement and the first product output time. It is recommended that styrene, ABS, EPS, PS-related traders and downstream processing enterprises incorporate Huajin Ami's driving dynamics into the key tracking framework and adjust the regional procurement strategy in advance.
