Abstract
A container holds a mix of liquid and gaseous crude oil. A barrier layer of balls, beads or similar, floats on the liquid surface, physically trapping and returning any vapour formed by gas bubbling, back to the liquid portion, thus providing a gas portion substantially free of vapour.
Description
Liquid Carryover Control System
Description
Introduction.
Crude oil, as it comes from the well, is a mixture of oil, water, gas and solids in varying proportions. These are separated by many different processes in order for oil companies to sell the various products such as butane and propane gas, petrol, diesel and lubricating oil, and bitumen and heavy asphalt products.
When the pressure in the well is relieved, the gas bubbles out of the iiqud ice a tizzy drink and is piped away separately. In successive separation stages the pressure is dropped to near atmospheric where the product is stored in the large crude oil storage tanks. Gas continues to be liberated perhaps like aiiat fizzy drink, but the* quantity is large due to the huge volume of liquid crude oil. This low pressure gas is piped from the top of the tanjs and cpmpressed and liquefied in a process referred to as condensate recovery. Refer to Figs I & 2 of drawings.
The gas contains droplets or mist of crude 0 whi can be harmlul to the downstream processes, polluting process equipment, compressors and other plant with oil, asphalt and other contaminants.
iiters aid "knock ou vessels are used to get dd of these products and leave pure gas but their success is limited. This patent proposes a solution to control droplets leaving the liquid surface.
Patent Principle This patent document describes a system to stop or limit the formation of droplets at the surface of the liquid crude.
The basic principle is described below.
In many industries wheç hot or vçltile iquis are used for cleaning or other applications, a layer of floating balls is placed on the surface of the liquid both to control splashing and aporation and to conserve heat. In some processes air or gas is bubbled through liquids such as cleaning solvents to agitate the liquid and wash any articles which are immersed. This allows baskets of components or individual items to be lowered through the layers of balls and into the bubbling liquid.
The balls imrndiately seal the surface after this is done, and again when the items are removed. Specialist companies manufacture balls of all sizes in a whole range of materials with resistance to various solvents, oils and other liquids, polypropylene being one of the commonest and cheapest.
g 3 shows how a bubbte can throw qd droplets into the space above the surface and fig 4 shows how a floating layer of particles can dampen this action.
ihs App Hcaion This patent s or the appiicaton oa oang layer o?b1is or pathcies on the surface of the crude oil which has the effect of rçducing or stoppin.g the droplets of oil which are carried over with the gas as mist to the next process. The particles are optimised in size and shape asjs the ttliclsness of the layer in order to absorb the energy of the bursting bubbles so that no liquid droplets are thrown into the space above the liquid.
Trials, show that tiny particles of plastic in the shape of beads or toroids are very effective but this patent is to cover all shapes and sizes of floating particles of any material, used to control the liqui rryove into the gas stream. These may be as small as sand or larger than tennis bafls, with layers of any thickness. Layers of floating particles about 10 ceitimetres.thick hve been found yery effective with toroidal shaped plastic particles about 2 mm diameter, removing around 95% of the droplets present without this layer on the urface.
This patent covers also various methods for applying and removing the particles, as well as methods of preparing materials and particles suitable for this application.
This patent covers all applications of liquid carryover due to bubbling gas liberating droplets into a stream of gas.
ig I and ig 2 show how the system s arranged hen appiled to crude di tanks, and fig 3 and fig 4 show how gas energy is absorbed by a layer of particles floating on the liquid surface.
Newness and novelty Liquid carryover has been a proIem in the dl industry or a long time and many solutions have failed. The normai. approach.is to remove the droplets fr* the gas stream after liberation from a surface, but this method prevents the liquid droplets from forming at the source, the liquid surface. At low pressure it is not possible to use dense filters or cyclones because of the pressure drop. This method of controlling carryover has been provenfor.smatl simulations, working very successfully. No similar method is available within the major oil companies at the present time.
