Issues regarding the demand for control valves in natural gas processing plants
Thread Content
This post was last edited by 3929519 on 2012-5-8 at 11:40. I would like to ask everyone: in a natural gas processing plant, which units require a high level of precision and reliability from control valves, and which ones have lower requirements? Currently, the processing plant includes units for desulfurization and decarbonization, hydrocarbon removal, water removal, boiler rooms, condensate stabilization, water supply and drainage systems for the condensate tank area, as well as fire protection systems. To control costs, it is planned to use imported control valves for applications that require high precision and reliability, while domestic valves will be used for those with lower requirements. Thank you all. Also, if anyone knows of any good brands of control valves, whether domestic or foreign, could you please suggest them? I only know that FISHER is a good brand for control valves. Thank you again
The control valves we use are all Gorter products made in the Netherlands; we rarely use ones made in China. I hope this can help you
I’m not sure if anyone has heard of the self-acting pressure regulator from Mankenberg in Germany, but its price is slightly higher than that of Fisher’s!
When selecting a control valve, it is essential to first understand the process conditions thoroughly, and then choose the appropriate valve based on requirements such as material, temperature, pressure, and flow rate The locator must be imported; it has excellent reliability! For important applications where there is a large pressure difference, a large/small diameter, high temperatures, or special material requirements, it is recommended to use imported products such as FISHER\BAUMAN\SAMSONG, etc ； Domestic: Wuzhong and Shanghai Ziyi Plant 7 can do it! If you need help or want access to channels, contact me and I’ll help you get a discounted price!
I’m not sure if the original poster is working in the LNG industry, but generally, the control performance of the valves used for introducing raw gas should be good, as well as that of the valves leading to the storage tanks. This is because the pressure in the storage tanks is usually lower than that in the pipelines, in order to prevent pressure surges. Then there are the return valves. As long as the valve is selected correctly and the CV value is calculated in accordance with the process requirements, poor regulation generally will not occur. For valves, the Wuxi tooling we used before gave good results; there is also Fosse available for low-temperature applications. When it comes to domestic valves, Shanghai Fute and Wuzhong Instruments seem to be quite good. There are many imported brands, such as Fisher, Fox, Sonyラン, Nales, and many others. These are my opinions; please forgive any shortcomings.
Choose the right model in the initial stage, and then just compare different options more to be sure. If possible, I can send you the information on our company’s control valves.
