Two Phase Flow occurs when a gas is flowing in a confined space with a liquid. The flow profile and geometry in this instance varies widely as a function of the liquid and gas material properties as well as the flow rates through the pipeline. The Two Phase Flow Demonstrator apparatus is a small scale flow loop that can demonstrate Two Phase Flow phenomena in pipes at a variety of liquid and gas flow rates. It is important that the process operator understand the basics of Two Phase Flow Demonstrator in pipelines, especially as it pertains to the formation of the destructive slug flow regime. Certain flow regimes can be destructive to facility piping, and should be avoided where possible. The destructive effects of these flow regimes can be managed through the use of various piping geometries.
The air and water flow rates are continuously variable over a wide range of flow rates. This allows the operator to observe a wide range of two-phase flow regimes using this demonstrator. The Two Phase Flow Demonstrator is mounted on a movable cart for ease of movement and storage. Two Phase Flow Demonstrator uses air and water to create different flow regimes in the process piping. Air is supplied to the system by a low pressure blower, and water is supplied through a centrifugal pump.

Flocculation chemicals can be added to the rawwater in order to improve the flotation of the contaminants. The diatomiteprovided is suitable as a contaminant. Flotationprocesses are used to separate solids from a liquid. The flotation process mostcommonly used in water treatment is dissolved air flotation. The suspension tobe treated is placed in a tank. A pump transports the raw water, whichenters the flotation column via a vertical pipe. The air dissolves in the water under pressure. Part of the waterflows back to the pump via a bypass. The other part of the water enters apressure vessel filled with Pall rings. The height of the supply linecan be adjusted. The pressure vessel ensures asufficiently long dwell time to dissolve the air and to separate undissolvedair. A water circuit with pump is connected to the flotationcolumn. Two compressors supply air to the water circuit on the suction side ofthe pump.
The water then enters the flotation column from below via a valve. This causesa sudden drop in pressure to almost atmospheric pressure. The contaminants rise up in thecolumn together with the air bubbles. At the upper end of the flotation column,the contaminants enter a circulating channel. Since the solubilityof air increases with increasing pressure, the excess air forms small bubbles.The air bubbles accumulate on the contaminants.

The major advantage of AC three-phase over DC power systems isthat the electrical power is generated economically in large power stationsrelatively far from the end users, transported at high voltage over longdistances with very little power loss and finally made available to theconsumers providing them with two different levels of voltage depending on theapplication needs. Today, the public electric power is supplied almostexclusively using three-phase systems with frequency of 50 or 60 Hz, dependingon the country.

The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravity separation of the gas, liquid hydrocarbon and water phases. The three phase separator demonstration apparatus is a small scale vessel that performs continuous separation of a mixture of oil, air and water. The process has manual control valves with rotameters and is intended to demonstrate oilfield separation principles with basic visual manual operation. It is available in horizontal and vertical orientations. This trainer includes a clear horizontal primary separator vessel.
Function:
This fluid mixture then flows into a separator vessel fabricated of clear materials. This process trainer blends air, water and refined oil to emulate a crude oil stream. The oil and water are recycled; the air is vented to atmosphere.

The unit consists of an inclinable channel mounted on a frame, together with a discharge tank and recirculating pump. The channel slope is adjusted by means of a fine screw jack to which an accurate slope indicator is attached. To commence a demonstration, sand is placed evenly along the channel bed, between the inlet tank and the overfall discharge weir. The channel sides are transparent in order that bed profile changes can be observed, and a section of one side is provided with graphical grid markings to permit quantitative assessments to be made of bedform dynamics. Water is circulated around the system at one of the three selectable flow rates.
Equilibrated soil samples placed on the sand are then subjected to a known variable suction range of 0- 800mm of water. These equipment consists of a free-standing circular tank filled with saturated sand (not supplied). The suction is applied by means of a buried porous pipe and an associated sliding control chamber. In order to maintain the suction an uninterrupted low volume water supply is required.
