We have a natural gas three stages reciprocating compressor having 0.6 bar g suction and 31 bar g discharge.

last month we found that its third stage rod packing temperature rises, what is the reason behind it?

Please be reasonable and use common sense.  A 3-stage reciprocating compressor can be configured in various ways:

• horizontal
• vertical
• Y-configured
• balanced-opposed
• in tandem
• etc.

Draw a schematic diagram and communicate how your compressor is configured and how the packing glands are located.  Our members are not capable of reading your thoughts ......

 

Tell us the intermediate pressures (although we can guess...) and the temperatures that you are describing as rising.  Tell us the history of the packing gland in question - whether it has been inspected and its conditions, as well as the piston rod involved.  Has the "trueness" and alignment of the rod and packing been confirmed by a reliable millwright?  Tell us all the back ground.

 

Await your specific data.
