Reciprocating piston compressor: Application case
Baogang Co., Ltd. coke by-product technology upgrading project
Background and significance:
The project will construct a 100,000-ton/year crude benzene hydrotreating unit, including pre-distillation column, stabilization column, main reactor and other production equipment, as well as supporting facilities such as circulating water system and fire protection system.
Through technological upgrades, this project will enhance Baotou Steels resource utilization efficiency and environmental performance in coke by-products, driving the company toward refined and efficient operations.
Supplying products and services: 2 reciprocating piston compressors
Project Significance: Our two reciprocating piston cycle gas compressors enable pressurized recycling of circulating gas, stabilize hydrogenation system pressure, and adapt to process conditions. This helps reduce operational costs, achieve green and low-carbon goals, ensure stable production capacity and product quality, while demonstrating the compatibility and reliability of our equipment in industrial gas recycling compression.
