Jiujiang Petrochemical Desulphurization Dry Gas Compressor Group Investment

Sinopec Jiujiang Petrochemical Company recently completed a key technical renovation project involving its refinery equipment—the 1.2 million tons per year hydrogenation unit. As part of this upgrade, a new desulfurization dry gas compressor unit was installed and successfully driven after two months of construction and commissioning. This investment addressed critical production bottlenecks and significantly advanced the company’s efforts toward clean energy production. Jiujiang Petrochemical has been actively adopting and promoting energy-saving and emission-reduction technologies to optimize both its refinery equipment and production processes. The newly added desulfurization and dry gas compressor is a symmetrically balanced unit that uses oil-free lubrication, reducing maintenance needs and improving operational efficiency. After desulfurization, the dry gas produced during the refining process is pressurized by the compressor and then sent to the PSA (Pressure Swing Adsorption) unit for hydrogen purification. The PSA plant utilizes advanced energy-saving gas separation technology, enabling the efficient removal of multiple impurities in one step. This allows high-purity hydrogen—previously considered waste—to be recovered and reused effectively. By doing so, the company maximizes the value of hydrogen resources within the refinery, contributing to sustainable development and improved economic returns. This project not only enhances operational efficiency but also supports Sinopec's broader goals of environmental protection and energy conservation, demonstrating the company's commitment to innovation and green manufacturing practices.

Stone Grinding Mill Machine

Small Raymond Mill,also called high pressure roller mill, fine power grinding mill, stone ginding mill machine. The grinding mill machine includes Ball Mill, raymond mill, Wet Pan Mill and rod mill machine. They are applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.

While the ball mill can divide into 2 types, wet ball mill and dry ball mill. Ball mill is a mineral processing machine for milling the materials into powders after they are crushed. It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries.
