One of the technologies now that is used for transporting fluids like gases, liquids, and slurries are pumps. This is composed of three major groups which are the gravity, direct lift, displacement pumps. A positive displacement helps in transporting fluid through trapping a certain quantity of fluid and then displacing it to the exit or the discharge pipe.
Gravity pumps are also called as hydraulic rams. These are used by taking water from the underground to higher areas in lower elevations. Multiphase pumping technologies have types and features which includes helicoaxial, twin screw pumps, progressive cavity, electric submersible, and buffer tanks. The advantages of multiphase production are simpler and smaller installation, lesser equipment cost, and increase in production rates.
A helicoaxial is also called as centrifugal. Centrifugal is used by transporting fluids through converting rotational kinetic energy into hydrodynamic energy. The rotational energy comes from the electric motor, and the fluid will then enter the impeller which is near the rotating axis, and the impeller is going to accelerate it, flowing outwards.
A twin screw have two intermeshing screws which will force the fluid movement that is pumped. High volume of gases and fluctuation of the inlet conditions are two types of pumping conditions which are commonly used. To seal these two shafts, four mechanical seals are required.
Progressive cavity is one type of the positive displacement. Sequence progress of small, fixed shape, discrete cavities is used in this type while the rotor is turned. This also acts as motor or mud motor if the solution is being pumped through the interior. Well drilling can be one good application for this.
An electric submersible contains a hermetically sealed motor which is close coupled to the pump. The construction is submerged to the solution that is being pushed. One main advantage of using this is it prevents cavitation, which is a problem about the difference of pump and fluid surface. Submersibles are more efficient than jets, since it pushes liquids to the surface, while jets pulls liquids.
Buffer tanks Cobourg ON usually are placed upstream in the suction nozzle of pump in case slug flows will happen. This will help break the liquid slug energy, smoothen fluctuations of flows coming, and acts as a sand trap. Usually, pumps are rated by flow rate, horsepower, inlet pressure in the head, and outlet suction in the head. The head is being simplified as the amount of feet and meters that the pump will raise and lower the column of the water within atmospheric pressure.
Materials that can be used in a pump includes stainless steel, cast iron, and some more. The material will depend on the application of the pump. For pharma application in water industries, stainless steel is commonly used because high temperature of stainless steel can give better result.
So by the name itself, multiphase have many variations of services and conditions like changing composition of liquid processes, temperature variations, operating high and low pressures, and exposure to abrasive or erosive media. So the challenge for this is to look for appropriate arrangement of mechanical seal and support system to ensure effectiveness and also to ensure quality as well.
