    • 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.

    • An injector includes a housing, a fixed core, a movable core, a valve member, and a resilient member pressing the valve member toward a nozzle hole. An inner peripheral surface of the housing axially guides an outer peripheral surface of the movable core. The inner peripheral surface and the outer peripheral surface define an outer clearance therebetween. The valve member includes a shaft-shaped portion and a stopper portion, which contacts the movable core and has a stopper inclined surface. An outer peripheral surface of the shaft-shaped portion and an inner peripheral surface of an insertion hole of the movable core define an inner clearance therebetween. The stopper inclined surface inclines radially inward of the shaft-shaped portion axially toward the nozzle hole. An axial clearance is formed between the stopper inclined surface and the movable core radially outward of a contact portion between the stopper inclined surface and the movable core.
