Parr Instrument Company Tubular Reactor Systems 5400 Designing and Building Quality Pressure Apparatus for 120 Years

Series Number: Series 5400 Continuous Flow Tubular Reactor Systems Bench Top or Floor Stand Vessel Sizes, mL: Maximum Operating Temperature, °C: Tubular reactors are used in a continuous flow mode with reagents flowing in and products being removed. They can be the simplest of all reactor designs. Tubular reactors are often referred to by a variety of names: - - - - - - Pipe reactors Packed-bed reactors Fixed-bed reactors Trickle-bed reactors Bubble-column reactors Ebullating-bed reactors Single-phase flow in a tubular reactor can be upward or downward. Two-phase flow can be co-current...

Series 5400 Tubular Reactor System Specifications Tubular reactor systems are highly customizable and can be made to various lengths and diameters and engineered for various pressures and temperatures, and materials of construction. A split-tube furnace is provided for heating these vessels. Insulation is provided at each end to minimize heat losses and prevent the end caps from being heated. The heater length is normally divided into one, two, or three separate heating zones, although it can be split into more zones if required. A fixed internal thermocouple in each zone can be furnished...

Series Number: Series 5400 Continuous Flow Tubular Reactor Systems Liquid Metering Pumps High pressure piston pumps are most often used to inject liquids into a pressurized reactor operating in a continuous-flow mode. For low flow rates, HPLC pumps, many of which are rated for 5000 psig, are excellent choices. Typical flow rates for pumps of this type range up to 10 or 40 mL per minute. Pumps are available to accommodate manual control from their digital faceplate or computer-control from a 4871 Process Controller. Chemical feed pumps are our recommendation for continuous feeding of liquids...

Control and Data Acquisition Systems A variety of solutions exist to meet the needs of system operators. System accessories such as heaters, mass flow controllers, and pumps can be obtained with individual control packages to create a Local Control System (LCS) based on our 4838 and 4848 Controllers. As the number of channels to be controlled increases, economics and convenience will often dictate that the system of individual controllers should be replaced with the computer-based Model 4871 Process Controller (PCC). This continuous flow stirred reactor system is on a cart with our Modular...

Series Number: Fluidized Bed Reactors Fluidized Bed Reactors are used extensively in and removal of catalyst. This is advantageous the chemical process industries. The distinguishing when the solids bed must be removed and Floor Stand feature of a fluidized bed reactor is that the bed of solid particles or catalyst is supported by an up flow of gas. This reactor provides easy loading Vessel Geometry: 1" ID, 36" length, with 2.5" ID, 2" length disengagement zone or custom Standard Pressure MAWP Rating, psi (bar): Up to 3000 (207) based on temperature replaced frequently. A high conversion...

Pressure Sensor (Not Shown) Reactor Outlet (To Cyclonic Separator) Fluidized beds have been significantly utilized in chemical processes in which parameters such as diffusion or heat transfer are the major design parameters. Compared to packed bed, a fluidized bed has notable advantages such as better control of temperature, no hot spot in the bed, uniform catalyst distribution and longer life of the catalyst. Nearly all significant commercial applications of fluidized bed technology concern gas-solid systems. Applications of fluidized bed reactors include but are not limited to gas-solid...
