Is it necessary to use nitrogen for a trial run when initially starting up the syngas compressor and the ammonia compressor?
When nitrogen is available, it is best to conduct a test run using nitrogen. It is also possible to conduct a test run using clean air in the absence of nitrogen; generally, combustible gases are not used. Or liquefiable gases.
It can be used if conditions permit; otherwise, use air. Pay attention to the pressure – it must not be too high. Air can also explode. How to use air? Haha, just remove a section of the imported valve.
Nitrogen or air can be used for the load testing. Given the difference in molecular weights between nitrogen or air and the process gas, the data obtained during testing may differ from those obtained when the process gas is in use; this aspect needs to be taken into account!
It is recommended to consider carefully. The surge curves vary depending on the medium. It is recommended to communicate with the compressor manufacturer to obtain approval.
It is possible to check whether the operating instructions for the compressor provided by the supplier contain information on this matter. It is generally necessary to conduct a trial run using nitrogen (or air) before the actual operation begins; however, it is essential to determine the appropriate value for the final exhaust pressure based on the pressure at the nitrogen inlet site. (It is best to provide these data to the compressor supplier so that they can carry out the calculations) to ensure that the piston force, exhaust temperature, and shaft power do not exceed acceptable levels.
