MANUFACTURING EQUIPMENT FOR PREPARING NEOPENTYL GLYCOL HAVING HIGH PROCESS EFFICIENCY

摘要

The present disclosure relates to an apparatus for producing neopentyl glycol with high processing efficiency. More particularly, the present disclosure relates to an apparatus for producing neopentyl glycol with high processing efficiency, which comprises: a hydrogenation reactor including a hydrogenation catalyst therein; a material feed line for supplying hydroxypivaldehyde solution to the hydrogenation reactor; a discharge line for discharging a neopentyl glycol product produced from the hydrogenation reactor; and a recycling line for recycling a part of the discharged neopentyl glycol product to the hydrogenation reactor, wherein a pre-heater is installed in the material feed line, and a circulator and a heat exchanger are installed in the discharge line. According to the apparatus for producing neopentyl glycol with high processing efficiency of the present disclosure, it is possible to prevent clogging of the lines to solve the time- and system-related troubles. It is possible to increase productivity, since there is no clogging of the lines and shut-down of the apparatus. There is no need for carrying out line cleaning even when the apparatus is operated again after shut-down for a predetermined time. It is possible to make continuous flow with no additional driving power, thereby avoiding a need for input of additional energy, or to make continuous flow merely by using a small amount of hydrogen extracted from a hydrogen feed line without significant modification of the existing lines, thereby providing high cost-efficiency.
