α-pyrrolidone, also known as 2-pyrrolidone, is an important chemical raw material. It is mainly used as a raw material for polyvinylpyrrolidone (PVP) monomer N-vinylpyrrolidone (NVP). It is also a high-grade solvent.

UW2100 universal intelligent controller is a small programmable controller successfully developed by Hangzhou Youwen Automation in cooperation with Zhejiang University, Shanghai Electric, Shanghai Baoxin, etc. on the basis of the national 863 "High-end Large-Scale Programmable Automation Controllers and Systems" research and development with the system. This article first briefly introduces the functional characteristics and technical advantages of the controller, and by analyzing the working principle of the heat exchange station, the 2100 controller is closely integrated with it, thereby increasing the heat exchange efficiency to more than 90%.

Petroleum is a complex mixture composed primarily of hydrocarbons. The relative molecular masses of hydrocarbons and non-hydrocarbon compounds in petroleum range from tens to thousands, and the corresponding boiling points range from normal temperature to over 500 degrees. The molecular structures are also diverse.

Oil and gas boiler power generation has a history of more than 60 years in China. The boilers built in Northeast my country at that time are still operating safely today. The currently developed oil-fired boilers and gas-fired boilers add energy-saving, environmentally friendly and other technologies to the original gas generators, making them efficient, energy-saving, safe and environmentally friendly technologies.
