Description
DIVISIONAL APPLICATION (3) TO CA 0,242,1141 DESCRIPTION
On (Fig.13) is shown the oil-separating vessel-container (Florentine) combined for light and heavy oils. Two-sectional glass module for primary check of presence of ethereal oil in the entering in Florentine distillate and a glass chamber for edging the already released ethereal oil.
The separating vessels (Florentine) work on the principle of the interconnected vessels. They ensure a constant release of water and in some cases of oil. The separation of the components of the mixture in it becomes possible due to their practical inability to mix and the difference concerning their density. Depending on the relative density of the ethereal oil its layer is above the water or under it and respectively in a separating vessel for light oils, heavy oils or combined- both for light and heavy oils.
The separating ability of the receptacles for light oil is determined by the ratio K=-Vi Where: K- the separating ability;
Vi - the velocity with which the oil comes to the surface, mis;
Vi- the velocity of sweeping along of the oil drops by the distillate downward, m/s.
The speed of coming to the surface of the oil drops is determined by the of Stoke's law:
Vi=d! z- i Where: d -is the equivalent diameter of the oil drops, m;
pi-the density of the oil, kg/W;
p2- the density of the water, kg/m';
g- the acceleration of gravity, m/s2;
0- the dynamic viscosity of the water, kg/ (m.s).
At pvpi (light oil) Vi is a positive, i.e. the oil comes to the water surface.
DIVISIONAL APPLICATION (3) TO CA 0,242,1141 At pi>p2 Vi is negative, i.e. the oil sinks to the bottom of receptacle.
The velocity of movement of the distillate downwards depends on its capacity and on the working section of the receptacle, i.e. on the surface through which the distillate drains down.
V~Q
- S
Where Q- is the capacity of the incoming distillate, m3/s;
S- is the surface of the section of the working part of the vessel, m2.
It is accepted that for a normal part of the receptacle V2 shouldn't be greater than 0,001 m/s at an unidirectional movement of the distillate and the ethereal oil, while at an polydirectional 0,0005 m/s.
From the above pointed formulas it is seen that the better separation of the oil is ensure at a lower velocity of distillation , larger drops of the ethereal oil, greater difference in the density of the oil and water and small viscosity of the water. The last two factors depend on the temperature of the distillate. The more the temperature rises the more the difference between the density grows and the viscosity of the water decreases, which facilitates the separation of the oil from the water. Knowing that water at 3,98 C, two molecules water unite in one molecule 2(I-120) then the water has the greatest density. The size of the drops of the ethereal oil depends on the speed of condensation. The gradual condensation favours the formation of large drops of ethereal oil. The high temperature of the outgoing from the coolers cooling steam allows the gradual condensation.
It is accepted that the capacity of the separating vessel of the periodical functioning apparatuses at average speed of distillation is enough t be 2-3 % of the capacity of the distillation apparatus. For the good quality of separation it is necessary the distillate to stay in the vessel at least 15-20 minutes. The separating vessels are usually located one per distillation apparatus but in case of expensive oils two vessels are located consecutively. The second has a controlling function. When working with expensive oils it is usually resorted to gathering the material from all the apparatuses in one bigger receptacle, which results in less smearing, losses due to evaporations and pollution.
DIVISIONAL APPLICATION (3) TO CA 0,242,1141 Florentine (Fig. 13): (87) - periodically cleaned filter gathering the depositions and particles from the oil sacks; (88) - cover hermetically sealing glass chamber (89), in which the primary edging is made and is determined the thickness of the oil ring of the entering distillate in the oil-separating vessel. By closing of cock (90) periodically a test is made for the oil content in the distillate; Thus by means of testing samples is controlled the duration of the process of boiling; (91)-module for periodical edging; (92, 114 and 115) silicone, ensuring the hermetical sealing of the cconnections of the glass modules with the respective modules of the (Florentine); (93) - pipe through the distillate is supplied to the working cone vessel (107), ending in its lower part with a perpendicular spoon (94), by which the direction of movement of the distillate is changed vertically upward. In that way the trajectory of movement of the distillate is prolonged and the time for oil discharge; (95) - a cock which under normal working conditions is closed and when necessary can be used for transferring the distillate into a second separating vessel or for direct use of the ethereal-oil water; (96) - a cock which is constantly open and is closed only when cock (95) is open or when is made a high-speed draining of the already separated light oil. Then both cocks - (95) and (96) are closed so that the entering distillate in (107) raises the level only in chamber (107), whereas the level of the liquid in chamber (121) does not change. In the process of permanent incessant draining of the light oil by half-closing of cock (96) the capacity of the entering distillate is regulated through cock (96) in chamber (121) to smaller than the capacity of the distillate entering from pipe (93). In chamber (107) this leads to a gradual raising of the level only in chamber (107) and a continued draining occurs by edging in glass chamber (113) of constantly releasing ethereal oil; (97) -hollander technological coupling which provides easy assembly and disassembly if cock (96) becomes defective; (98) - a cock for draining the already separated secondary light oils; (99) - a cock with pipe (108) for diverting the water separated from the distillate (at work it is always open);
(100) - cock for emptying or draining of the separated secondary heavy oils;
(101) - a cock for draining of (107) or for heavy oils; (102) - air-vent with stopper (103) for hermetical sealing. The stopper is removed during a process of non-high-speed draining of the released ethereal oil as cock (99) is closed resulting in raising the level in chamber (118) that gradually starts to fill up. If the stopper (103) is not removed it may cause babbling with bubbles in the already separated light oil so this may disrupt its clarity and quality; (104) - oil-diverting pipe of the already edged oil in chamber (125); (105) - heavy oil; (106) - light oil; (107) - a primary working chamber for oil-separation. It is DIVISIONAL APPLICATION (3) TO CA 0,242,1141 conformable with the formula of decreasing sweeping in downward direction and that is why chamber (107) has the form of an asymmetric frustum of a cone. The lower base of the cone is bent toward cock (101) with the purpose of normal gathering and draining of the heavy oils when such are processed; (108) - a pipe intended to ensure the constant process of overflow of water sucking from the middle part of the Florentine (121) in order to be at an equal distance from the secondary light and heavy oils and not to affect the normal heat exchange sucking up the coldest water from below; (109) - a cone pipe, an overflow drain of the water from the primary chamber (107) to the secondary chamber (121). The construction of overflowing by means of the cone pipe (109) is made so as to get a difference between the levels of the liquids so that the level in chamber (107) to be higher than the level in chamber (121) thus to preserve one of the basic ideas referring the normal heat exchange between the liquids in chambers (107) and (121). Not to disrupt the interconnected vessels but at the same time to ensure a greater difference between the temperatures of the releasing light oil (106) and the temperature of the water in the lower part of chamber (121) must approach the temperature with which the water has the greatest density-3,98 C. In that way is preserved the formula of the speed of coming to the surface of the oil drops, defined by Stoke's law Vi=d2(na-oi)& so that the water to be with the greatest density, but at the same time the temperature in the upper part of chamber (107) where the light oil is, to be the highest ensuring a process of maximum oil-release. If we accept that during a polydirectional movement of the distillate and the ethereal oil Vz= 0.0005 mis for 20 min in a vessel with cylindrical form , as the section is one and the same along the section of the column in the process of release of the oil the oil drops will pass a 60 centimeters column. That is why chamber 107 has the form of a cone, along the vertical plane the section is variable, towards the base the section enlarges from which it follows that V2 decreases. At V2=0.0004 m/s for 20 min is necessary 48 cm column with V2= 0.0003 m/s for 20 min it is 36 cm column, etc. The narrowing of the section of the cone along the vertical plane causes the released oil drops to accelerate in their movement upwards, whereas the distillate moving downwards decreases its velocity. The idea of the so designed construction is to achieve a maximum high parameter for Vi and maximum low parameter for V2. Thus we achieve a maximum ability of separation K and the Florentine is multifunctional, applicable to raw materials DIVISIONAL APPLICATION (3) TO CA 0,242,1141 with small content of ethereal oil as well to materials with greater content of ethereal oil. Its quality parameters are not changed after the connection of more than one distillery.
After the experiments that have been made with the Florentine with capacity 120 litres three distilleries can be connected with working capacity of 1000 liters. (110) - thermometer; (111) -hermetically sealing cover;
(112)- bolts with nuts screwed tight and ensuring the hermetical quality between the modules and the glass chamber (113); (113) - glass chamber which serves to exert visual control over separating oil from water during the draining of the oil in the dehydrator (124); (116) -module with a small volume of chamber (125) with the purpose of making a direct edging of the oil.
That is also convenient for processing of materials both with small content of ethereal oil and with greater content of ethereal oil; (117) - a horizontal base for tightening between modules (116) and chamber 107 of the glass chamber (113); (119) - vertical base; (120) - secondary light oil;
