Call for case studies on ammonia synthesis plant startup accidents!
Thread Content
Our company intends to start producing synthetic ammonia; we would like to ask about accident cases that occurred during operations, and we hope everyone can help analyze the causes
While driving, many of the instrument electronics are in the debugging phase, so a shutdown of the vehicle is normal. I recommend that interlocks be put into use as much as possible; otherwise, in the event of a failure, it could lead to serious accidents such as damaged equipment and burned catalysts.
Three sets of dry gas seals for the synthetic compressor have failed consecutively! !
1. Interlocks are recommended for compressors and Roots blowers. Prevent over-oxidation caused by negative pressure at the compressor inlet. 2. High and low level alarms for the gas tank to prevent the fan from operating under negative pressure. The gas tank top flipped over.
Why isn’t there a detailed analysis of any accident cases? They’re all too simplistic
Last year, our factory. The gas scrubber of the desulfurization system was deflated after being shut down. The reason is that a liquid seal occurred in the operating desulfurization system, resulting in an increase in the system pressure difference. The reduction is not timely. Negative pressure at the compressor inlet caused the gas scrubbing tower of the decommissioned desulfurization system to collapse. Thinking about it now is still shocking. Safety in production cannot be taken lightly! ! ! ! ! ! !
You need to learn how to search on forums; there are many such posts. http://bbs.hcbbs.com/thread-418723-1-1.html
Did the motor explode when starting the ammonia synthesis cycle machine (turbine type)?

At that time, since the gasification and air separation purification systems had not been completed, the low-pressure refined gas from the old system was used to carry out heating and reduction. One day after one month of operation, the exhaust pressure of the dry gas seal reached the interlock value, causing the system to shut down. Upon further inspection, traces of water were found in the dry gas seal filter. Due to the high water content in the low-pressure purified gas, moisture enters the dry gas seal, damaging it.
