The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravitational separation of the gas, liquid hydrocarbon and water phases. Gas flow passes through a secondary vertical 2-phase separator, or knock-out ports to remove any further liquids from the gas stream. Mini Plant Large Scale Three Phase Separator process trainer blends air, water and refined oil to emulate a crude oil stream. This fluid mixture then flows into a horizontal separator vessel fabricated of clear PVC. The entire trainer is controlled from a distributed control system (DCS). The separator is equipped with industry typical process instrumentation.

Electronic drive units independently control both motors. Meters show motor electrical power consumption of each motor. A close-coupled load cell on each motor measures torque. Sensor on each motor measures speed, shown by a digital indicator. This test set has two independently-controlled, motor driven compressors, inter cooler and air receiver. It works as a single-stage, two-stage or two-stage compressor with inter cooler. The product of the torque and speed gives true shaft power. To allow students to study different types of air compressor systems, diverter valves allow air to move in different directions. All controls and instrumentation are on an easy-to-operate mimic panel. Electric motors and low-maintenance toothed belts drive two twin-cylinder, air-cooled reciprocating compressors. These include:
From the first stage to the receiver
To the second stage, by means of the integral water cooled inter cooler
Directly to the second stage
Compressors:
Twin cylinders
Maximum delivery pressure 10.3 bar
Speed range 200-1000 rev.min1
The Magnetic Pump Learning System curriculum explains the function, operation, installation, disassembly, inspection, and maintenance of a magnetic pump. The Magnetic Pump Learning System covers the magnetic pump, which uses a magnetic coupling to prevent direct contact between the motor drive shaft and the pump impeller. Additional topics include: how to properly align the magnetic coupling; how to troubleshoot problems; how to select the correct magnetic pump for an application; how to determine a pumps flow/pressure characteristics; and how each component of the pump factors into the overall operation. This feature eliminates any possibility of leakage or seepage and makes the magnetic pump an ideal selection for pumping hazardous chemicals that could harm the environment or for expensive liquids where it is important to reduce loss.
The Magnetic Pump Learning System includes a polypropylene housed, c-face mounted magnetic pump with a centrifugal impeller, a piping network, a magnetic coupling, and a relief valve. In fact, all of the included components are industrial-grade and will allow learners to gain immediate hands-on experience and practice that can apply to real-world mechanisms. The polypropylene housing is chemically resistant, which allows the magnetic pump to move fluids such as acids, alkalis, plating solutions, sterile solutions, and brine for applications in hospitals, chemical laboratories, and wineries. This commitment to providing learns with top-flight equipment is one reason why is the worlds leader in skills-based, interactive technical learning.

The working principle of the apparatus is the following: an air flow generated by a centrifugal fan enters a tunnel passing through a fluid thread rectifier. As the air passes through the tunnel it undergoes a series of treatments, until it arrives in the last chamber, which represents the environment to be conditioned. The Air Conditioning Study Unit With Climatic Chamber And Air Recycle Circuit has been developed for insertion in the most advanced educational subjects. Simplicity and clearness are the fundamental requirements that permit the teacher and students to operate without having to deal first with complicated utilization procedures. Before this last stage, it may be pre-heated and moisturized by water diffusers, to experiment on heating environments and to have the opportunity to vary as many parameters as possible for a complete study on air conditioning. The flow is pre-heated, then moisturized by steam diffusers it is cooled through the evaporator and sent to the final chamber.

The present invention relates to a flow control apparatus for a positive-displacement pump such as rotary-vane pump, plunger pump, gear pump, and more particularly to the flow control apparatus for keeping a flow rate of fluid discharged from the pump at the high rotational speed which is lower than a flow rate of fluid discharged from the pump at the low rotational speed. The unit enables students to investigate the effects of changing the parameters of the control algorithm (proportional band, integral action and derivative time) on the control capability of the system.
