BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to reactors for conducting polymerization of monomers, and in particular, bulk polymerization reactors for conducting polymerization of alpha-olefin monomers.
2. Description of Related Art
Formation of polymers from various monomers is a well-known art. As is also well known in the art, the polymerization reactor in which the polymers are formed from the monomers have certain inherent limitations to efficiently form the polymers. A major inherent limitation is the removal of heat from the polymerization reactor created by the chemical reaction between the monomers and the catalyst during formation of the polymers. To overcome this problem, cooling systems have been designed to encase the polymerization reactor in an attempt to remove the heat from the polymerization reactor. Additionally, cooling additives may be included in the polymerization reaction mixture in the polymerization reactor.
Both of these prior attempts, however, have various shortcomings. For example, the use of cooling systems outside the polymerization reactor do not efficiently and effectively remove heat from the polymerization reactor, especially for the center most region of the polymerization reactor. Accordingly, the size of the polymerization reactor must be small and limited amounts of polymer may be formed in each reactor batch. Additionally, with respect to the addition of cooling additives to the polymerization reactants, these cooling additives can have an adverse effect on the quality of the polymer as well as increasing the cost associated with forming the polymer.
In other prior attempts, as discussed in U.S. Pat. Nos. 5,449,732, entitled Solvent Free Oil Soluble Drag Reducing Polymer Suspension, 5,504,131, entitled Solvent Free Oil Soluble Drag Reducing Polymer Suspension, and 5,504,132, entitled Solvent Free Oil Soluble Drag Reducing Polymer Suspension, the polymerization reactor is a crystalline, hydrocarbon-insoluble organic polymer reaction enclosure capable of substantially preventing passage of oxygen and water, i.e., plastic bags. Use of these plastic bags permits the polymerization reaction to be carried out without a cooling system or addition of cooling additives. However, because the plastic bags are not provided with any assistance in the removal of heat from the polymerization reaction, only small amounts of polymer reactants, e.g., monomer and catalyst, can be included in each plastic bag. As such, only small amounts of polymer can be formed in each of this type of polymerization reactor. Further, the plastic bags can not be easily separated from the polymer, and thus, are not re-useable.
Accordingly, prior to the development of the present invention, there has been no polymerization reactor or process for forming polymers, which: effectively remove heat away from the polymerization reactor; permit the formation of a large amount of polymer in each polymerization reactor; do not require the addition of cooling additives; and permit the use of a re-useable polymerization reactor. Therefore, the art has sought a polymerization reactor and a process for forming polymers, which: effectively remove heat away from the polymerization reactor; permit the formation of a large amount of polymer in each polymerization reactor; do not require the addition of cooling additives; and permit the use of a re-useable polymerization reactor.

While the invention will be described in connection with the preferred embodiment, it will be understood that it is not intended to limit the invention to that embodiment. On the contrary, it is intended to cover all alternatives, modifications, and equivalents, as may be included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
Broadly, the polymerization reactor of the present invention includes a reservoir and a lid having a heat exchanger. When the lid is placed on the reservoir, the head exchanger is disposed within the reservoir thereby cooling, i.e., removing heat from, the contents of the reservoir.
Referring now to FIGS. 1-3, in one specific embodiment of the present invention, polymerization reactor 40 includes reservoir 80 and lid 70. Lid 70 includes heat exchanger 60. Reservoir 80 includes at least three wall surfaces and a bottom wall surface to form a cavity. As shown in FIGS. 1-3, reservoir preferably includes four side wall surfaces, 81, 82, 83, 84, and bottom wall surface 85 to form reservoir cavity 87. While it is to be understood that additional wall surfaces may be included as part of reservoir 80, thereby permitting reservoir 80 to have any desired shape, preferably reservoir 80 includes four wall surfaces thereby having a rectangular shape (FIGS. 1-3), or cube shaped.
Reservoir 80 preferably includes at least one skid 88. As shown in FIGS. 1 and 3, reservoir 80 includes two skids 88. Skids 88 permit a forklift, or other lifting device, to engage reservoir 80 so that it can be moved to any desired location, i.e., to be placed near sources of monomer that are to be charged, or transported, into reservoir 80.
As shown in FIGS. 1 and 3, reservoir 80 includes length 92, height 91, and width 93. Length 92, height 91, and width 93 may be any distance as desired by the person using polymerization reactor 40. It is to be understood, however, that generally, as length 92 increases, the number of heat exchanger plates 66 also increases, and as height 91 and width 93 increase, the dimensions of heat exchanger plate 66 increases. In one specific embodiment, length 92, height 91, and width 93 are equal and each are at least 2 feet. In this embodiment, polymerization reactor 40 is cubed shaped. In a preferred embodiment, length 92 is at least 3 feet, height 91 is at least 2 feet, and width 93 is at least 2 feet. In this preferred embodiment, polymerization reactor 40 is rectangularly shaped.
Reservoir 80 may be formed out of any material known to persons of ordinary skill in the art. Preferably, reservoir 80 is formed out of stainless steel.
Referring now to FIGS. 1-3, lid 70 includes top wall surface 73 and side wall surfaces 72, 74, 75, 76. Lip 71 may be included to provide additional strength. Lid 70 provides protection to heat exchanger 60 from the environment and prevents items from falling onto heat exchanger 60 and into reservoir 80. Lid 70 also includes an inner surface 77 to which heat exchanger 60 is attached. Lid 70 may be formed out of any material known to persons of ordinary skill in the art. Preferably, lid 70 is formed out of stainless steel.
Heat exchanger 60 preferably includes plate hanger assembly 61, coolant inlet manifold 62, coolant outlet manifold 63, at least one coolant inlet conduit 64, at least one coolant outlet conduit 65, and at least one heat exchanger plate 66 having exchanger cavity 69. Hanger assembly 61 preferably includes bracket 59 to permit attachment of each heat exchanger 66 to lid 70.
Coolant inlet manifold 62 is in fluid communication with at least one coolant inlet conduit 64 which is in fluid communication with heat exchanger plate 66. Likewise, coolant outlet manifold 63 is in fluid communication with at least one coolant outlet conduit 65 which is in fluid communication with heat exchanger plate 66. In one specific embodiment, having one heat exchanger plate 66, one of each of coolant inlet conduit 64 and coolant outlet conduit 65 is in fluid communication with coolant input manifold 62 and coolant outlet manifold 63, respectively. In other embodiments having more than one heat changer plate 66, as shown in FIGS. 1-3, each heat exchanger plate 66 includes at least one coolant inlet conduit 64 and one coolant outlet conduit 65 in fluid communication with coolant inlet manifold 62 and coolant outlet manifold 63, respectively. Therefore, coolant is permitted to pass from coolant source, through coolant inlet manifold 62, through each of the at least one coolant inlet conduits 64 into exchanger plate cavity 69 of each of the at least one heat exchanger plates 66, from the exchanger plate cavity 69 through coolant outlet conduit 65, through coolant outlet manifold 63 and back to coolant source. In so doing, heat is removed from the polymerization reaction mixture, i.e., the polymerization reaction mixture is cooled.
As discussed above, coolant inlet manifold 62 and coolant output manifold 63 are in fluid communication with coolant source. Acceptable coolant sources include, but are not limited to, refrigeration units readily known to persons of ordinary skill in the art employing water, water-glycol mixtures, water-alcohol mixtures, dissolved mineral salts, e.g., sodium chloride and calcium chloride, and ammonium as coolants. In this arrangement, coolant may be circulated from the coolant source, through a conduit, e.g., pipe or flexible hose (not shown), into coolant inlet manifold 61. Coolant is then permitted to enter coolant inlet conduit 64 and into exchanger cavity 69 of each heat exchanger plate 66.
Coolant then is permitted to exit each exchanger cavity 69 of each heat exchanger plate 66 through coolant outlet conduit 65 and into coolant outlet manifold 63. Coolant is then transported back to coolant source from coolant outlet manifold 65 through a conduit, e.g., pipe or flexible hose (not shown) to be recharged, i.e., cooled, and circulated back through heat exchanger 60.
Referring now to FIGS. 1-2, each heat exchanger plate 66 is formed from front wall surface 51, back wall surface 52, and at least one side wall surface 53 to form cavity 69. Heat exchanger plate 66 also includes length 67, width 68, and thickness 55. Heat exchanger plate 66 may be any shape and formed out of any material desired or necessary to provide sufficient area to cool the polymerization reaction mixture in reservoir 80. Preferably, heat exchanger plate 66 is formed from aluminum. As shown in FIGS. 1-3, each heat exchanger plate 66 includes four side wall surfaces 53 although it is to be understood that heat exchanger plate 66 may be circularly shaped. In embodiments having more than one heat exchanger plate 66, each heat exchanger plate is disposed at a distance 56 from the next heat exchanger plate 66.
In a preferred embodiment, each heat exchanger plate 66 includes a removable film, e.g., plastic sheath, to prevent polymer formed in reservoir 80 during polymerization from adhering to each heat exchanger plate 66. Suitable removable films include plastic sheeting, plastic sheath, a spray-on non-stick substance that is incapable of being polymerized by the polymerization reaction mixture, for example, because the spray-on non-stick substance has a melting point higher than the temperature of the polymerization reaction mixture.
The number of heat exchanger plates 66 present in each embodiment of polymerization reactor 40 is determined by the size of reservoir 80. In the specific embodiment illustrated in FIGS. 1-4, reservoir 80 includes length 92 of 8 feet, 3 inches, height 91 of 4 feet, 1 inch, and width 93 of 4 feet, 3 inches, and each heat exchange plate 66 includes length 67 of 4 feet, width 68 of 4 feet, and thickness 55 of approximately 7⁄8 inch. Seventeen heat exchanger plates 66 are disposed along plate hanger assembly 61 with distance 56 between each heat exchanger plate of approximately 4 13/16 inches. It is to be understood that all of the foregoing dimensions may be altered as desired or necessary to provide sufficient cooling of the polymerization reaction mixture and to optimize polymer functionality.
The polymerization reactors 40 of the present invention may be used to polymerize monomers into polymers, and in particular, alpha olefin monomers into polyalphaolefins. As mentioned above, numerous polymerization methods, reactants, i.e., monomers, catalysts, cocatalysts, are known to persons of ordinary skill in the art. Additionally, bulk polymerization methods are known to persons of ordinary skill in the art. However, none of these known polymerization methods have been conducted in the polymerization reactors 80 discussed above.
In one specific embodiment of the present method for polymerization, at least one monomer and at least one catalyst are combined to form a polymerization reaction mixture in reservoir 80. Lid 80 having at least one heat exchanger plate 66 is then disposed on top of reservoir 80 to protect the polymerization reaction mixture from the environment. During placement of lid 70, each of the at least one heat exchanger plates 66 are inserted into reservoir 80, and thus, the polymerization reaction mixture. Preferably, lid 70 is lowered in the direction of arrow 99 during insertion of each of the at least one heat exchanger plates 66 into the polymerization reaction mixture. Coolant is then permitted to passing from the coolant source and into, and then out of, each exchanger cavity 69 of each of the at least one heat exchanger plates 66. During circulation of coolant through each heat exchanger plate 66, the polymerization reaction mixture is cooled. Each heat exchanger plate 66 is permitted to contact the polymerization reaction mixture for a length of time necessary for a majority of the monomers to be polymerized into polymer. Lid 70 may then be moved in the direction of arrow 98 for removal of each of the at least one heat exchanger plates 66 from the polymerization reaction mixture.
It is to be understood that the invention is not limited to the exact details of construction, operation, exact materials, or embodiments shown and described, as obvious modifications and equivalents will be apparent to one skilled in the art. For example, each of the heat exchanger plates may include more than one coolant inlet conduit or more than one coolant outlet conduit. The dimensions and shapes of the polymerization reactors can be easily determined by a person of ordinary skill in the art. Moreover, additional diagnostic gauges may be included as part of the polymerization reactor, e.g., for monitoring temperature during the polymerization reaction. Additionally, the shape of the heat exchanger plates may be any shaped desired or necessary due to the shape of the reservoir, e.g., circularly-shaped, rectangularly-shaped, triangularly-shaped, trapezoidally-shaped, etc. Accordingly, the invention is therefore to be limited only by the scope of the appended claims.
