Abstract

Abstract:

Two urea reactor cylinders seriously fractured in 1995 and 2005 in China. The possibility analysis of chemical explosion in the reactor and some concrete calculation were given, and then compared with the damage of the actual failure. It indicated that the energy generated from the chemical explosion of material in the reactor could not cause a serious fracture of the two urea reactors and great damage to the surroundings. Therefore, the cause of the urea reactor fracture was not a chemical explosion but boiling liquid expanding to vapor explosion.

Key words: urea reactor; chemical explosion; gas-phase space; explosion energy
