An apparatus and method for dehydrating water-containing oil according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of an apparatus for dehydrating water-containing oil.
In this example, dimethyl ether (DME) is used as the liquefied hygroscopic solvent.
As shown in FIG. 1, a water-containing oil dehydration apparatus (hereinafter referred to as “dehydration apparatus”) 10 is a pressure type dehydrator (hereinafter referred to as “dehydration process”) in which a predetermined amount of water-containing oil 11 is introduced and pressurized. And a hygroscopic agent supply means 14 having a pressure tank 14a and a pressure pump 14b for introducing liquefied dimethyl ether (liquefied DME) 13 as a liquefied hygroscopic solvent into the pressurized dehydrator 12 from the bottom. The water is taken into the liquefied DME 13 side which is a liquefied hygroscopic solvent and dehydrated.
In FIG. 1, reference numeral 19 is a pressure pump, 21 is an oil tank, 22 is a dehydration oil tank, L 0 is a supply line for supplying the water-containing oil 11 to the dehydrator 12, and L 1 is a supply line for supplying the liquefied DME 13. , L 2 is a discharge supply line for discharging liquefied DME, L 3 is a supply line for supplying vaporized DME, V 0 and V 4 valves are on-off valves, V 1 and V 3 discharge valves, and V 2 is a pressure control valve Are respectively illustrated.
ここで、本発明で液化吸湿性溶剤として用いるジメチルエーテル（ＤＭＥ）は、例えば８ａｔａ以上の高い圧力で液化し、例えば５ａｔａの圧力で気化するものである。
これは、吸湿剤として高圧の液化状態で水分を吸湿し、その後低圧側にしてフラッシュさせることで気液分離し、例えば蒸留等の操作等を不要として、水分除去操作及び回収操作の簡略化を図るようにしている。
本発明で液化吸湿性溶剤としては、ジメチルエーテル以外には、例えばメチルエーテル、フロンガス、代替フロンガス、イソブタンガス、ノルマルペンタン等を挙げることができる。
Here, dimethyl ether (DME) used as a liquefied hygroscopic solvent in the present invention is liquefied at a high pressure of, for example, 8 ata or higher and vaporized at a pressure of, for example, 5 ata.
This is because moisture is absorbed as a hygroscopic agent in a high-pressure liquefied state, and then separated into a gas-liquid by flushing to a low-pressure side, for example, eliminating the need for operations such as distillation, simplifying the water removal operation and the recovery operation. I try to figure it out.
In the present invention, examples of the liquefied hygroscopic solvent include methyl ether, chlorofluorocarbon gas, alternative chlorofluorocarbon gas, isobutane gas, and normal pentane other than dimethyl ether.
本実施例では、液化ＤＭＥ１３を脱水器１２の本体底部側から徐々に供給し、供給された液化ＤＭＥ１３が頂部側に向かって上昇し、液化ＤＭＥ１３の層を油層の上側に形成する。
この液化ＤＭＥ１３が上昇する際に、油中に浮遊する水分と接触し、液化ＤＭＥ１３の吸湿作用により、油中の水分が移行され、液化ＤＭＥ１３側に溶け込むこととなる。
In the present embodiment, the liquefied DME 13 is gradually supplied from the bottom side of the main body of the dehydrator 12, and the supplied liquefied DME 13 rises toward the top side to form a layer of liquefied DME 13 on the upper side of the oil layer.
When the liquefied DME 13 rises, it comes into contact with moisture floating in the oil, and the moisture in the oil is transferred by the hygroscopic action of the liquefied DME 13 and dissolves into the liquefied DME 13 side.
なお、液化ＤＭＥ１３と油との接触効率を向上させるために、内部を攪拌する攪拌手段を設けるようにしても良い。そして、一度液化ＤＭＥ１３内に取り込まれた水分は、油側に戻ることはないので、水分除去が確実となる。 In order to improve the contact efficiency between the liquefied DME 13 and the oil, a stirring means for stirring the inside may be provided. Since the water once taken into the liquefied DME 13 does not return to the oil side, water removal is ensured.
水分を取り込んだ液化ＤＭＥ１３は、比重が軽いので油の上に供給した分だけ溜まり、水分を取り込んだ液化ＤＭＥ１３の層（上層）と、油１１の層（下層）とに分離される。 Since the liquefied DME 13 that has taken in moisture has a low specific gravity, the liquefied DME 13 accumulates as much as it is supplied onto the oil, and is separated into a layer (upper layer) of the liquefied DME 13 that has taken in moisture and a layer (lower layer) of the oil 11.
また、撹拌手段を用いる場合には、その攪拌を停止し、静置させることで、水分を取り込んだ液化ＤＭＥ１３の層（上層）と、油１１の層（下層）とに分離される。 Further, when the stirring means is used, the stirring is stopped and left to stand to separate into a layer (upper layer) of liquefied DME 13 that has taken in moisture and a layer (lower layer) of oil 11.
脱水の完了は、油層に設けた水分計４０により計測している。
ここで、水分計４０としては、例えば近赤外線水分計、静電容量水分計等の公知の水分計を用いることができる。
Completion of dehydration is measured by a moisture meter 40 provided in the oil layer.
Here, as the moisture meter 40, for example, a known moisture meter such as a near infrared moisture meter or a capacitance moisture meter can be used.
また、脱水器１２の後流側の液化ＤＭＥ１３を排出する排出供給ラインＬ2に気化器１６が介装されている。そして、水分を取り込んだ液化ＤＭＥ１３は、静置分離した後、排出弁Ｖ1を開いて抜出し、気化器（圧力：５ａｔａ）１６においてフラッシュさせて、気液分離している。 Further, a vaporizer 16 is interposed in a discharge supply line L 2 for discharging the liquefied DME 13 on the downstream side of the dehydrator 12. The liquefied DME 13 that has taken in water is left to stand and separated, and then the discharge valve V 1 is opened and pulled out, and is flushed in the vaporizer (pressure: 5 ata) 16 for gas-liquid separation.
ここで、気化器１６側の圧力を５ａｔａと低圧側に操作することで、高圧（８ａｔａ）での脱水器１２から抜出された水分を含む液化ＤＭＥ１３が気化し、分離水３０と気化ＤＭＥとに気液分離される。なお、気化器１６の調圧ラインＬ6には圧力調節弁Ｖ2を設け、圧力を例えば５ａｔａ程度と調節している。 Here, the liquefied DME 13 containing water extracted from the dehydrator 12 at high pressure (8 ata) is vaporized by operating the pressure on the vaporizer 16 side to 5 ata and low pressure side, and the separated water 30 and vaporized DME are vaporized. Gas-liquid separation. Note that a pressure control valve V 2 is provided in the pressure adjustment line L 6 of the vaporizer 16 to adjust the pressure to, for example, about 5 ata.
前記気化器１６で気化した気化ＤＭＥは、送給ラインＬ3に介装した加圧ポンプ１９を介して気化ＤＭＥを液化しつつ、圧力タンク１４ａ側に送液し、再利用するようにしている。 Vaporized DME vaporized by the vaporizer 16, while liquefy vaporized DME through the pressure pump 19 interposed feed line L 3, was fed to the pressure tank 14a side, so as to re-use .
気化器１６で分離された分離水３０は、抜出しラインＬ4に介装された排出弁Ｖ3を開いて分離水タンク３１に抜出し、ここで分離水３０を保管している。 The separated water 30 separated by the vaporizer 16 is drawn out to the separated water tank 31 by opening the discharge valve V 3 interposed in the drawing line L 4 , where the separated water 30 is stored.
脱水完了後、静置して二層とし、下層側の脱水処理油を脱水器１２の底部から抜出しラインＬ5に介装された開閉弁Ｖ4を開いて脱水処理油タンク２２に抜出し、ここで保管される。
なお、連続で油の脱水処理をする場合には、油タンク２１に戻すようにしても良い。
After completion of the dehydration, it is allowed to stand to form two layers. The lower layer dehydrated processing oil is extracted from the bottom of the dehydrator 12 and the on-off valve V 4 interposed in the line L 5 is opened to be extracted into the dehydrated processing oil tank 22. Stored in
Note that when the oil is continuously dehydrated, it may be returned to the oil tank 21.
本発明によれば、液化吸湿性溶剤としてジメチルエーテル（ＤＭＥ）を用い、これを液化した液化ＤＭＥを接触させて、油中に含まれる水分を、簡易な構成で除去することができる。また、脱水操作に伴う消費物質がない、サイクル方式での脱水が可能となる。
脱水効果においては、液化ＤＭＥを等量用いることで、水分を０．３〜数％程度含有する油から水分を除去して、０．１％以下の含水率とすることが可能となる。
According to the present invention, dimethyl ether (DME) is used as the liquefied hygroscopic solvent, and the liquefied DME obtained by liquefying the dimethyl ether is brought into contact with the liquefied hygroscopic solvent to remove water contained in the oil with a simple configuration. Further, the dehydration can be performed in a cycle manner without the consumption substances associated with the dehydration operation.
In the dehydration effect, by using an equal amount of liquefied DME, it is possible to remove the water from the oil containing about 0.3 to several percent of water, and to obtain a water content of 0.1% or less.
よって、高度の脱水をする必要がない油や、温度処理により劣化が激しい生物分解性油に対しての粗脱水（例えば水分含有量０．１％以下）に適用することとなる。 Therefore, the present invention is applied to rough dehydration (for example, water content of 0.1% or less) for oil that does not need to be highly dehydrated or biodegradable oil that is rapidly deteriorated by temperature treatment.
以上のように、本発明に係る水分含有油の脱水処理装置及び方法によれば、水分を含む油から溶解水を簡易な設備で効率よく処理することができ、例えば燃料油、潤滑油の処理が簡易になる。 As described above, according to the apparatus and method for dehydrating water-containing oil according to the present invention, it is possible to efficiently process dissolved water from oil containing water with simple equipment, for example, processing of fuel oil and lubricating oil. Becomes simple.
脱水処理としては、１日に１回、水分除去の為の脱水処理装置への脱水処理運転を行うことで、常に所定水分量以下の油を維持することができる。
例えば１００Ｌの油を処理する場合でも１００Ｌ用いることがなく、２０〜３０Ｌの液化ＤＭＥの使用量で済むこととなる。
As the dehydration process, the dehydration process operation to the dehydration apparatus for removing the water is performed once a day, so that the oil having a predetermined water content or less can always be maintained.
For example, even when processing 100 L of oil, 100 L is not used, and the amount of liquefied DME used is 20 to 30 L.
また、液化ＤＭＥは寒冷地でも高温地でも使用できるので、水分含有油の脱水処理に適用場所を選ぶ必要がない。 In addition, since liquefied DME can be used in cold or high temperature areas, there is no need to select an application site for dehydration of water-containing oil.
