Abstract

A method and means for purifying petrochemical products in a circuit circulating such products at a pressure of about 2 to 6 bar, comprising heating the petrochemical product and maintaining the temperature to about 100 °C, passing the product through a nozzle of approximately 0.7 to 1.2 mm thereby to increase the velocity of the product, thereby separating different components of the product, returning separated clean petrochemical product to the circuit, and draining steam and gaseous parts.

Description

Method and means for purifying petrochemical products
The present invention is related to a method and means for removing alien liquids from petrochemical products.
The automotive industries have problems with alien liquid contaminations in petrochemical products for lubrication and different power transmissions or transformers (hydraulics, gears, valves, etc.). These contaminations mainly consist of water (from condensation, leaks, frost, etc.), not combusted fuel residues, acids and possibly other alien liquids depending on the local conditions. Acids can only form when water is present.
For the industry it is important to keep the liquid petrochemical products free from such liquid contaminations. This is achieved with the method according to the present invention as defined by the features stated in the claims.
The drawing discloses in figure 1 a longitudinal section of a combined filter and purifier for petrochemical products according to the present invention, figure 2 discloses a general view of a special distillation element according to the invention, figure 3 discloses a longitudinal section of a nozzle in the element, figure 4 discloses a vertical section of the element, figure 5 discloses a side view of the element, and figure 6 discloses an enlarged section through the top of the element end the top of the chamber.
The special distillation element 1 according to the invention is placed vertically in a ventilated chamber 2 as part of a filter and purifying means comprising a filter chamber 10 and a lid or cover 3. In the ventilated chamber 2 the liquid petrochemical products enter in at a flow of 20 - 35 liters per hour under a pressure of 2 — 6 bar through a tube 8. The tube 8 is heated to keep it at a constant temperature of about 100 °C. Immediately thereafter the liquid passes through a metering jet or nozzle 5 with an opening of 0.7 - 1.2 mm, where the velocity of the liquid is accelerated because of the sudden pressure release. Partly because of the different thermal properties of different components of the liquid mix passing through such as oil, water, fuel, etc.; these components will react differently to these sudden changes of temperature, pressure and velocity.
A fractional separation of the components will occur and these separated materials will partly be in gas form and partly as liquid when it leaves the metering nozzle 5 like a spray or fountain hitting the cover 3 creating the ceiling of the chamber 2 that directly above the nozzle 5 is formed like the inverted inside of a dome 4. The materials in the gas or in an evaporated form, the gas like steam from water and acids, possibly gasoline and other alien liquids, are vented out via a not disclosed ventilation opening due to an overpressure that will occur due to the gas formation. The light and oil-diluting parts of possible diesel fuel will also be evaporated out in this process. The petrochemical liquid will be reflected down from the dome 4 in the ceiling of the chamber 2 to the head 9 of the distillation element 1 and will flow down over its surface which is also heated to about 100 0C. This surface is formed like a pear or mushroom with grooves to delay the surface velocity of the liquid in order to "distillate" possible alien liquid remains. The liquid flows to the bottom of the distillation chamber 2 where it is drained back to the actual equipment through a not disclosed outlet.
An important part of the invention is the shape of the distillation element and the ventilated chamber 2 with its inverted dome 4 in the ceiling of the chamber 2.
The distillation element 1 is preferably made of aluminum because of the good thermal conductivity. The element 1 has a shape like a mushroom or pear.
An electrical heating element for heating the distillation element is inserted into a heating element bore 7 in the head of the element 1. A thermostat for control of the temperature in the head of the distillation element 1 is installed in a thermostat bore 6 in the head of the distillation element 1.
The surface of the distillation element 1 it provided with grooves to trap or slow down the liquid flow.
The distillation element according to the present invention provides high performance with few parts, whereby said parts are inexpensive to manufacture. Said low price is especially remarkable when compared with the high performance. Furthermore the distillation element according to the invention is easy to install and use and need no maintenance.
The method and means according to the present invention is especially suitable to remove water from oil, such as hydraulic oil, oil in combustion engines, gasoline and diesel etc. The distillation element 1 may be used alone in a circuit or in combination with a filter packet 11 in a filter chamber 10 of a filter or purifying box as disclosed in figure 1. Oil enters the filter box through a port 12, flows downwardly along the outside of the filter 11, penetrates through the filter 11 and enters the pipe 8 of the distillation element 1.
