【3D Process Flow】Summary Post – Useful for learning about the process flow: https://bbs.hcbbs.com/thread-5711616-1-1.html ---------------------------------------------------------- - Reciprocating Ultra-High Pressure Compressor: The reciprocating ultra-high pressure compressor (Hyper Compressor) is the key equipment in the production process of low-density polyethylene (LDPE). The diagram clearly shows the three functional areas of the device: the central motion mechanism area, which includes the crankshaft and crosshead that convert the rotational motion of the motor into back-and-forth linear motion ; The open isolation section in the middle is used to physically separate the lubricating oil system from the ethylene gas system ; And the outermost high-pressure compression zone. This compressor is designed for extreme pressure conditions, and it is capable of compressing ethylene gas to a pressure of up to 3,500 bar, thereby giving it supercritical fluid properties. The diagram shows the key components, including the dark gray mirror-polished tungsten carbide plunger used to withstand extremely high pressures, as well as the high-pressure cylinder assembly made up of a series of disc-shaped packing cups stacked together. The device features a unique concentric combination valve design, as well as a high-pressure oil injection lubrication system and a cooling water circulation path that are necessary to ensure its stable operation under extreme conditions. This compressor can achieve an exhaust pressure of 3,500 bar and a drive power of over 30 MW.
