【Ten Years of Rapid Development in Chemical Processing Equipment】From 1974 to 2013: In 2013, Shenyang produced the first 4M150 reciprocating hydrogen compressor for residue hydroprocessing

Witnessing the ten-year rapid development of chemical processing equipment, I praise the prosperity and strength of modern China. More people’s participation makes things even more lively; with you here, Haichuan becomes even better. This is just a preliminary contribution – I invite everyone to get more involved in discussions on this forum. Replies will be rewarded; feel free to discuss! ------------------------------------------------- The new 4M150 hydrogen compressor for crude oil hydrogenation is a key piece of equipment at Sinochem Quanzhou Petrochemical. The rated flow rate of this equipment reaches 83,000 Nm3/h, and the overall piston force per unit of the machine exceeds 1,000 KN; therefore, 150-series reciprocating compressors must be used. Before 2013, no products in China could meet these requirements, and abroad only companies such as Drayson Lan, GE, and Thomson were capable of producing such compressors. Given that major projects do not give domestic equipment any chance, how can Chinese manufacturing become stronger? After thorough research, Sinochem Quanzhou Petrochemical collaborated with Shenmu Group, a leading domestic enterprise in petrochemical equipment, to work together on developing the first 4M150 new hydrogen compressor in China. As early as 2008, SHENGU introduced the technology of 125-ton high-thrust reciprocating compressors from Porschke Turbomachinery in Germany, and made innovative improvements to this technology. Subsequently, based on the digestion and absorption of foreign technologies, SHENGU carried out independent re-innovation by introducing a newly developed four-row symmetrically balanced 125-ton reciprocating compressor for Sinopec Changling Petrochemical’s 1.7 million tons per year residue hydrogenation project. These two super-large products quickly seized the lead in the domestic market. From two-row symmetrically balanced 125-ton reciprocating compressors, to four-row symmetrically balanced 125-ton reciprocating compressors, and then to four-row symmetrically balanced 150-ton reciprocating compressors, there has been a continuous development toward ultra-large-scale units; the 150-ton high-thrust reciprocating compressor represents a historic breakthrough.

In early 2011, SHENGU received requests from various petrochemical clients for the specifications of the 4M150 unit. After discussions with design institutes, it was decided to develop the 4M150 unit based on the new hydrogen compressor project used in Sinochem Quanzhou Petrochemical’s 3.3 million tons per year residue hydrogenation plant. In December of the same year, the China General Machinery Industry Association organized a review meeting for the 4M150 unit design. The experts present agreed that the technical proposal submitted by Shenyang Steam Turbine Group was feasible, that the necessary manufacturing conditions were available, and that the unit could meet the technical requirements of large-scale petrochemical and coal chemical industries; therefore, trial production could be carried out based on this project.
The successful development of the M150 unit has fulfilled the aspiration of the employees at Shenyang Blower Group to create world-class products, strive to enter high-end markets, and expand their influence from a single point to a broader scale. Its significance lies not only in replacing foreign imports and filling domestic gaps, but also in enhancing the competitiveness of the domestic equipment manufacturing industry, expanding the market scope for the domestic petrochemical sector, and creating new sources of economic growth for enterprises. The 4M150 new hydrogen compressor project was unanimously recognized in the expert evaluation organized by the China Machinery Industry Federation as filling a gap in domestic production, with all its performance indicators reaching international advanced levels. Compared to imported equipment, this domestic equipment saves tens of millions of yuan in investment (per unit). Currently, the device is working well.
