Polymerization reactor

Номер: CA2114314C
Автор: David J. Lawrence, Donald A. Williams, Michael F. McDonald, Jr.
Принадлежит: ExxonMobil Chemical Patents Inc

A novel chemical reactor; one particularly useful for the production of polymers, especially elastomers such as butyl rubber. The reactor (10) contains (1) a two-tube pass system, constituted of an inner or center tube bundle (20) through which a mixture or slurry of polymerizable monomers and catalyst is passed in one direction, and recycled via an outer tube bundle (30) in the opposite direction in essentially even flow distribution (2), while the tubes of the center and outer tubular bundles are maintained within a jacketed section, or sections of the reactor into which a coolant, or refrigerant; is injected and vaporized to remove the heat of reaction. The coolant, or refrigerant, in heat exchange relationship with the tubes removes the exothermic heats of reaction from the polymerization mixture, and maintains the polymerization mixture at uniformly low temperature. An even flow circulation of the slurry which aids in maintaining uniform low temperature, is provided by the use of (3) a diffuser (60) and (4) mixed flow pumping system (40), with its impeller (43), by virtue of which an adequate pressure head of even pressure profile is developed across the entry sides of the center tubes (20) to maintain the even flow distribution within the two-tube pass system at high circulation rate. There is no vortex whirl at the exit of the impeller-diffuser assembly, and no cavitation bubbles as commonly associated with one-tube pass systems, which employ a central draft tube and axial flow pump. Improved mixing, high hydraulic efficiency, and higher production rates with low polymer fouling, are achieved.

Poppet member for a control valve

Принадлежит: Bendix Corp

ABSTRACT OF THE DISCLOSURE A valve for use in a pressure differentially operated servo-motor to regulate the flow of fluid through a bore in a hub from first and second sources in response to movement of an input member by an operator. The valve has a resilient disc member with a peripheral surface and a central opening. First and second annular ribs symmetrically extend from opposite sides of the disc adjacent the central opening. A spring connected to the input member holds the peripheral surface in sealing engagement with the hub. In a first mode of operation, the spring holds the input member against the first annular rib to allow the fluid from the first source to freely communicate between first and second passages in the hub by way of the bore. In a second mode or operation, the input member moves out of contact with the first rib; however, the internal resiliency of the disc and a pressure differential created across the disc between the first and second sources of fluid moves the first rib into contact with a seat in the hub to inhibit flow communication of the fluid from the first source through the bore while allowing the fluid from the second source to freely flow through the second passage to create the pressure differential from operating the servomotor.

A bearing assembly (20) for a pump (12), e.g., an internai or externat gear pump includes a journal bearing block (20) having a length, a width, and an axial centerline (CL') passing through a center of the journal bearing block (20) with respect to the length. The journal bearing block (20) includes at least two journal bearing bores (21), the journal bearing bores (21) each having a center (C), wherein a bearing bore centerline (CL) extends between the centers (C) of the journal bearing bores (21) and in parallel with the bearing bore centerline (CL). The bearing bore centerline (CL) is offset with respect to the width of the journal bearing block (20) and the axial centerline (CL'). The bearing assembly (20) is particularly applicable to gear pumps, such as external gear pumps for fuel applications.
