Abstract

The invention provides a regeneration device and a regeneration method for adsorbent. The regeneration device comprises a regeneration gas buffer tank, a compressor, a first heater, a second heater, a primary cooler, a chiller, an adsorbent storage device, a waste gas cooler and a pressure balance tank, wherein regeneration gas is pressurized by the compressor and fed into the first heater; a heat source of the first heater comes from the reacted regeneration gas flowing out of the adsorbent storage device; the regeneration gas is subjected to primary heating, is fed into the second heater for further heating and is fed into the adsorbent storage device for a regeneration reaction; the reacted regeneration gas is subjected to heat exchange and cooling through the first heater, is successively fed into the primary cooler and the chiller for cooling and is returned into the regeneration gas buffer tank for recycling; and the regeneration gas failing to meet the requirements flows from the inside of the adsorbent storage device into the waste gas cooler for cooling, then enters the pressure balance tank, and is discharged into low-pressure gas of the whole plant to serve as fuel. The regeneration device has the characteristics of energy saving, high efficiency, environment friendliness and emission reduction.

Description

technical field [0001] The invention relates to the technical field of adsorbent regeneration methods, in particular to an efficient, energy-saving and environmentally friendly adsorbent regeneration device and regeneration method. Background technique [0002] The adsorbent is used to remove impurities such as sulfur and oxygen-containing compounds in the raw material of the downstream device. After the adsorbent has been in operation for a period of time, because it has a certain impurity adsorption capacity, it will accumulate a certain amount of impurities on the adsorbent, thereby Decrease the adsorption capacity of the adsorbent and affect the subsequent reaction units. Therefore, it is necessary to regenerate the adsorbent after adsorbing impurities to remove the impurities on it and restore its adsorption activity. The traditional adsorbent regeneration method is to use nitrogen as the regeneration gas. During the regeneration process, in order to achieve a better r...
