Method for energy recovery from oxidation reactor off-gas |
摘要 |
The present invention relates to a method for efficiently recovering energy from off-gas with high temperatures and high pressures released from the oxidation reactor of aromatic compounds such as xylene, pseudocumene, durene and the like. More particularly, the present invention relates to a method for energy recovery from oxidation reactor off-gas, which comprises subjecting off-gas with high temperature and high pressure from an oxidation reactor to heat exchange with cooling water to cool the off-gas, subjecting the cooled off-gas to direct counter-flow contact with the water heated by said heat exchange to obtain a mixture of off-gas and steam, and cooled water, circulating the cooled water for reuse as said cooling water for said high temperature and high pressure off-gas, and sending the mixture of off-gas and steam to an expander to recover energy therefrom. According to the present invention, the energy recovered from off-gas increases by an amount equivalent to the amount of steam saturating in and accompanying the off-gas.
