Can syngas leakage and pipe wall friction generate sparks? Why does syngas catch fire when it leaks?
High-pressure syngas leaks can generate sparks; this has happened in our plant. If the leak rate is high, pressure should not be reduced too quickly – instead, the load should be reduced gradually while releasing pressure, and nitrogen should be used for purging
Leakage of high-pressure syngas and friction against the tube wall cannot generate sparks. A leak fire is a fire caused by static electricity.
The principle behind this issue is actually quite simple: a fire occurs due to static electricity. The principle is the same as that of chains attached to oil tankers to prevent static electricity; both CO and H2 in syngas have low ignition points. But accidents like this are almost non-existent; it’s impossible for there to be such a large leakage. It only happens when the flow rate is high, resulting in significant frictional static electricity. When an accident like this occurs, it’s the fault of the operators and inspectors. . .
