Title:
Organic-solvent dehydration equipment
Document Type and Number:
Japanese Patent JP6024131
Kind Code:
B2
Abstract:
[Problem] To provide an organic solvent dehydration device that achieves a continuous purification of an organic solvent, basically does not require the replacement of a dehydration material, and can highly efficiently and stably eliminate water from a large quantity of organic solvent. [Solution] The organic solvent dehydration device dehydrates/eliminates water contained in an organic solvent to be processed by introducing the organic solvent to be processed and containing water to a dehydration material, causing contact to same. The dehydration material contains a plurality of spherically-shaped positive ion exchange resin pieces. The dehydration material has a particality of at least 90% at a particle size of the positive ion exchange resin of no greater than 0.4 mm. The organic solvent dehydration device has: a dehydration tank filled with the dehydration material; an introduction line for introducing the organic solvent to be processed into the dehydration tank; a decompressor that decompresses the interior of the dehydration tank; and a desorbed gas discharge line that discharges from the dehydration tank a gas desorbed from within the dehydration tank, and introduces same to the decompressor.
