Refining exchanges

This post was last edited by Qingfeng Lili on 2012-2-22 at 14:22. I would like to communicate with technical personnel from various oil refining companies – what are some good ways to get in touch? Please leave your contact information here so that we can stay in touch, exchange insights and experiences, or share data and information. For example, with QQ, those who are interested can leave their contact information, right?
Why do we still need QQ? This is the best platform.
:) What are the main processes used in our oil refining? Which types of valves are needed in large quantities during this process? Thank you
The main units include atmospheric and vacuum distillation units, catalytic cracking units (reaction and regeneration, fractionation, stabilization, dewaxing, gas separation, MTBE production), catalytic reforming units, delayed coking units, hydrogen production units, styrene production units, refining units, ethylene cracking units, and C4 utilization units. There are many types of valves, and various classification methods exist: 1. Classification by purpose and function: 1. Shut-off valves: These are primarily used to stop or allow the flow of fluids. Including gate valves, globe valves, diaphragm valves, plug valves, ball valves, butterfly valves, etc. 2. Control valves: Mainly used to regulate the flow rate, pressure, etc. of the medium. Including control valves, throttle valves, pressure reducing valves, etc. 3. Check valves: Used to prevent the backflow of the medium. Including check valves of various structures. 4. Diversion valves: Used for distributing, separating, or mixing media. Including distribution valves and steam traps of various structures, etc. 5. Safety valves: Used for overpressure safety protection. Including various types of safety valves. II. Classification by main parameters 1. Classification by pressure (1) Vacuum valves: Valves that operate at pressures below standard atmospheric pressure. (2) Low-pressure valve nominal pressure PN
