【発明の詳細な説明】
本発明は濃縮または蒸留を効果的に行なう方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for effectively carrying out concentration or distillation.
従来、高沸点を有する物質または熱的に不安定な物質の
濃縮及び蒸留には、減圧蒸留または水蒸気蒸留などの方
法が用いられてきた。Conventionally, methods such as vacuum distillation or steam distillation have been used to concentrate and distill substances with high boiling points or thermally unstable substances.
しかし、水分を嫌う物質を含有する場合や親水性の強い
物質を含む場合には水蒸気蒸留法は使用できす、また、
減圧蒸留法は、装置が複雑となること、排気ガス中に被
蒸留物の一部が混入し、これらが大気中に逸散し環境汚
染を来たす等の欠点がある。However, steam distillation cannot be used when containing substances that dislike moisture or containing highly hydrophilic substances.
The vacuum distillation method has drawbacks such as a complicated apparatus and a part of the distillate mixed into the exhaust gas, which is dissipated into the atmosphere and causes environmental pollution.
本発明者らは、例えば、石油留分を重合して得る、高沸
点分を含む石油樹脂留分を濃縮または蒸留して石油樹脂
を得る方法として、これらの欠点のない方法を種々検討
した結果、濃縮または蒸留の系内に不活性ガスを循環さ
せ、かつ濃縮缶または蒸留缶の底部より該不活性ガスを
吹込みながら濃縮または蒸留を行なうことにより、効率
良く濃縮または蒸留をなし得ることを見出した。The present inventors have investigated various methods that do not have these drawbacks, for example, as a method for obtaining petroleum resin by concentrating or distilling a petroleum resin fraction containing high boiling points obtained by polymerizing petroleum fractions. It has been shown that concentration or distillation can be carried out efficiently by circulating an inert gas in the concentration or distillation system and performing concentration or distillation while blowing the inert gas into the bottom of the concentration or distillation can. I found it.
以下、図面により本発明をさらに詳細に説明する。Hereinafter, the present invention will be explained in more detail with reference to the drawings.
第１図は、本発明の一実施態様に用いる回分式濃縮装置
の経路図である。FIG. 1 is a route diagram of a batch concentrator used in one embodiment of the present invention.
原料仕込管１により濃縮搭２に一定量の原料を仕込み、
ガス吹込ノズル３より不活性ガスを吹込む。A certain amount of raw material is charged into the concentration tower 2 through the raw material supply pipe 1,
Inert gas is blown from the gas blowing nozzle 3.
不活性ガスは、用いる原料に不活性なガスで通常窒素ガ
スが用いられる。The inert gas is a gas inert to the raw materials used, and nitrogen gas is usually used.
凝縮器４で留出物を凝縮し、受槽５で不活性ガスと留出
物を分離して、留出液ポンプ６で留出物抜出管７から留
出物を抜き出す。The distillate is condensed in a condenser 4, the inert gas and the distillate are separated in a receiver tank 5, and the distillate is extracted from a distillate extraction pipe 7 with a distillate pump 6.
一方不活性ガスは、循環管８を通して循環し調圧弁９で
圧調整を行う、もし設定圧以下になれば不活性ガスを吹
込みつ匁、循環ポンプ１０で不活性ガスを送り、設定圧
以上になった場合は調圧弁１１でガスをパージし、流量
調節弁１２で不活性ガスの流量を調節する。On the other hand, the inert gas is circulated through the circulation pipe 8 and the pressure is adjusted by the pressure regulating valve 9. If the pressure is below the set pressure, inert gas is blown in and the circulation pump 10 is used to send the inert gas so that the pressure is higher than the set pressure. If this occurs, the pressure regulating valve 11 purges the gas, and the flow rate regulating valve 12 regulates the flow rate of the inert gas.
また循環ガスは加熱器１３で温度を調節してノズル３よ
り吹込む。Further, the temperature of the circulating gas is adjusted by a heater 13 and then blown through the nozzle 3.
搭の温度は加熱器１４で調節し、缶部が所定の濃度にな
ったらタップ配管１５よりタップする。The temperature of the tower is adjusted by a heater 14, and when the can part reaches a predetermined concentration, it is tapped from a tap pipe 15.
第１図は回分式濃縮搭を示したものであるがこれと同様
の装置を数段直列に繋ぐことにより多段式連続濃縮を行
うことも可能である。Although FIG. 1 shows a batch type concentrator, it is also possible to perform multistage continuous concentration by connecting several stages of similar equipment in series.
又、不活性ガスの流量を精密に制御すること及び循環ガ
ス濃度を精密に制御することにより糸外に循環ガスを放
出することなく経済的運転が可能である。Furthermore, by precisely controlling the flow rate of the inert gas and the concentration of the circulating gas, economical operation is possible without releasing the circulating gas outside the yarn.
本発明は被濃縮物または被蒸留物の性質を損なうことな
く濃縮または蒸留を行うことができる。The present invention allows concentration or distillation to be performed without impairing the properties of the concentrate or distillate.
又、おおむね密閉系で行うため例えば有機低沸点物など
が大気中に逸散することがない。Furthermore, since the process is generally carried out in a closed system, organic low-boiling substances, for example, do not escape into the atmosphere.
次に実施例で本発明を詳述する。Next, the present invention will be explained in detail with reference to Examples.
