Jiujiang Petrochemical Aramatic Hydrocarbon Extraction Plant Successfully Energy-saving

Posted on

The key energy-saving renovation project at the refinery unit of Jiujiang Petrochemical Branch, Sinopec Corp., has reached a major milestone. The recent overhaul of the extraction tower in the 100,000-ton-per-year aromatics extraction plant has successfully gone into operation. The process parameters now meet all production requirements, effectively addressing long-standing issues that had hindered the efficiency of the aromatic extraction unit for years. Since the implementation of the energy-efficient aromatic hydrocarbon extraction tower, the plant has operated with greater stability, ensuring consistent product quality and significantly improving its resistance to operational disruptions. The extraction efficiency has seen a remarkable improvement, with the purity of non-aromatic hydrocarbons in the raffinate oil rising from 97% to 99%. This enhancement has also led to an increase in the aromatics recovery rate, allowing the facility to produce over 10 tons of "triphenyl" products daily. This successful upgrade not only boosts the plant’s productivity but also supports Sinopec's broader goals of energy conservation and sustainable development. The project is expected to deliver long-term economic and environmental benefits, setting a strong example for future refinery improvements.

Air Preheaters (APH)

An air preheater (APH) is a device used to heat air, commonly used in industrial boilers, thermal power plants, and other thermal energy facilities. APH improves the thermal efficiency of the boiler by transferring heat from the flue gas to the air entering the boiler through heat exchange with it.


APH usually consists of a Heat Exchanger with a number of parallel pipes inside the exchanger through which smoke and air flow to allow heat exchange. In APH, the smoke flows on the outside of the heat exchanger and the air flows on the inside so that the heat between the smoke and the air can be transferred through the pipe walls.


The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
