1.    GENERAL INFORMATION

The Vacuum Dehydration Oil Purification System is designed to remove free, emulsified and dissolved water, particulate and gaseous contamination from petroleum and synthetic based fluids. The water removal principle used is simple, reliable, and will dependably remove water well below the oil saturation point, even when tightly bound in an emulsion. Figure 1 on the next page shows schematically the systems operation. For the dehydration process, the fluid is first drawn into the heater of the system. It then flows through permanent dispersal media that is located inside the vacuum tower. The contaminated oil flows through the surfaces of this media where it is exposed to a vacuum, normally 22” Hg (559 mm Hg). The water and dissolved gases are boiled off and the fluid is dehydrated. An outlet pump removes the dry oil from the bottom of the vacuum chamber where it then passes through the filter housings and out the discharge of the system. For particulate removal, the system is typically equipped with a high efficiency filter element made from micro-glass media and rated Beta(c) > 1000 per ISO 16889, meaning that 99.9% of all particles of a given micron size are removed in a multi pass system.

The process fluid must be compatible with Buna seal material. Buna N is generally recommended for petroleum, water, diesel and water glycol. This unit may be ordered with other seals to provide compatibility with specialty fluids. Buna N is good in the temperature range of -65°F to +250°F.

 

7.    INSTALLATION AND START UP PROCEDURES

Unpacking

This system is delivered with maximum protection during transportation and handling.

NOTE: All damage attributed to the handling and delivery of the unit must be recorded and brought to the attention of the shipper immediately.

 

This system has been thoroughly tested for a minimum run time required to ensure proper operation. Fluid used to test the unit is matched as closely as possible to that listed on the application sheet completed by the customer and supplied with the order. The unit has been thoroughly inspected for defects prior to the delivery. All connections, however, should be checked prior to operating this unit, vibration and/or rough handling during delivery could adversely affect component alignment and/or connection tightness.

 

Mechanical Installation

 

With the system in place, connect the inlet and outlet hoses from the reservoir to the system. The inlet port has been sized to provide enough flow to operate the unit in the automatic mode using oil with a maximum viscosity of 1500 SSU (323.7 cSt). A hose diameter equal to inlet/outlet port size (see specification sheet) is required to provide adequate oil supply to this unit.

 

NOTE: Use of a smaller diameter line will restrict the flow and will adversely effect the automatic operation of the unit.

 

The inlet/outlet connections have been sized for maximum hose lengths of 35 feet. Use of longer hose lengths must be approved prior to installation. Use of a “quick disconnect” on the inlet line is not recommended. This can restrict flow to the unit in specific applications. Oil is drawn into the unit by vacuum created by the system and is capable of pulling oil with up to 8-ft. (2.4 m) of negative head. For applications that exceed this, please consult the factory.

 

Operating Instructions

 

Connect inlet and outlet hoses to the oil supply reservoir and system. Connect condensate sump discharge outlet to waste reservoir. Connect power supply cord to the electrical receptacle.

 

CAUTION: Supply Power Disconnect should be located within a line of sight to the

Power supply source.

 

Close all drain valves on the system.

 

Open all inlet and outlet valves on the system and the oil supply reservoir.

 

Supply power to the system. Turn the Main Power Disconnect to the ON position.

 

Check for phase failure. If the red light illuminates, phase failure exists. In that case, turn the Phase Reversal Switch to the opposite setting. Phase failure light should not be on.

 

Press the Start button.

 

Regulate the Pump Motor Speed Control (black dial) to the desired flow rate.

 

NOTE: The pump’s performance is regulated by the VFD’s motor frequency, and at 60 Hz, the pump will run at rated GPM. On the other hand, if the desired flow rate is half the rated GPM (for example), the knob should be set to 30 Hz.

 

Once the system is up and running, slowly open the air vent valves (on top of the filter housing) and bleed off the air in the vessels. Be sure that a container is placed under the vent valve while bleeding the air, as oil will come out after the air is purged.

 

After that, turn the heater switch to the ON position. The system is set at 150°F from the factory, but the temperature can be increased/decreased by pressing the scroll buttons on the Temperature Control. Normal maximum extraction rate is accomplished when the fluid is processed at a temperature between 140°–160°F.

 

IMPORTANT: It is important to never turn off the discharge pump while the heater is energized. This can cause the heater to overheat.

 

Next, observe the Vacuum Gauge pressure. Normal indication should be between18-26” Hg for the Vacuum Pump. If not, adjust the vacuum by opening or closing the Vacuum Regulator Valve located just below the Air Inlet Filter. This adjustment is gradual and does not respond quickly so there will be a 3-5 second delay in results when the adjustment is made.

 

WARNING: Do not operate the Vacuum Pump below 26” Hg. 18” to 26” Hg vacuum pressure is the ultimate vacuum for continuous operation of the Pump.

 

The system is now fully functioning. Normal discharge operating pressure is 5 –20 PSI. However, with restricted or long discharge lines the pressure can be higher. The pump is set from the factory to relieve at 100 PSI.

 

It is not recommended that you run the system at less than 30 HZ with greater than 30 PSI discharge pressure for extended periods of time. This can damage the VFD or motor on the system. A prime indicator of this operational default is error code EO24 on the VFD

 

When an alarm occurs, check the specific alarm indicator and solve it by using the Troubleshooting Section of this manual. After fixing the problem, press the Stop/Reset button and then press the Start button to run the system again.

 

To stop the system, close the inlet valve and allow it to run for approximately 30 seconds. The system oil will be returned to the reservoir. Then simply press the Stop/Reset button.

 

Close all valves from the reservoir and on the system.

 

Turn the Main Power Disconnect to the OFF position.

 

Auto Water Drain (Optional)

 

Located on the back side of the water sump are two electric switches, one on the top and the other on the bottom. When the system is in operation, water will begin to fill the sump. Once the water reaches the top electric switch, the auto water drain operation will begin. First, the vacuum isolation ball valve closes to keep the vacuum inside the main tower. Next, the system shuts down. The vent valve and drain valve then open simultaneously. The water then begins to drain. Once the water level in the sump falls below the bottom electric switch, the vent valve and drain valve will close. Finally, the system will start back-up and open the vacuum isolation valve. This cycle will repeat every time the water sump is filled. If there is a problem with the auto water drain, and the sump fills, the system will shut down after two minutes.

 

Vacuum Tower Bypass (Optional)

 

This operation is located on the back of system between the discharge from the heaters and the intake of the vacuum tower. The main function of this option is to isolate the flow from the heater pass the tower and through the discharge line back to the reservoir, eliminating the dehydration process. While the dehydration may be turned off, your heaters will still be engaged allowing the oil to heat up to the required temp. To enable this process you will need to close the inlet valve going into the tower, open the Tower Bypass valve and close the valve from the tower to the pump. After you open and close the proper valves, turn the Bypass Switch (VDOP Bypass Switch) to the ON position and adjust the motor speed accordingly to the situation at hand.

 

Housing Bypass (Optional)

 

This process enables the flow to bypass the filter housing located on the discharge side of the system. This process does not require any electrical components. In order to engage this process you must close the valve that allows the flow into the filter housing, then open the bypass valve and close the outlet valve from the filter housing to the discharge port. This process is critical due to it allows you to change the filter element when required with out having to shut down the system process. This will allow you to keep the dehydration and heater process to still be enabled, therefore you don’t have any down time in the middle of the job.

 

Filter Replacement Procedures

Before replacing the filter elements, first drain the housing by opening the drain (with a container below) and then open the vent valve. This will allow the atmospheric pressure to push down on the fluid inside the vessel. After draining the housing, loosen lid bolts in a counter-clockwise direction.

 

For micro-glass filter elements

 

Loosen t-nuts to remove the used filter elements.

Install new filters so that they seat properly at the bottom of the housing.

Tighten the t-nut to secure the new filter.

Make sure o-ring gasket is seated properly on the lid.

Seal the filter housing by tightening all the bolts for a proper seal.

 

For bag filter elements:

 

Lift out used bag filter.

Install new bag filter so that it seats properly at the top of the housing.

Make sure o-ring gasket is seated properly on the lid.

Seal the filter housing by tightening all the bolts for a proper seal.

10. MAINTENANCE

 

Vacuum Chamber Internal Dispersion Media

 

The dispersal media function is to maximize the surface area of the oil exposed to the vacuum by creating a thin oil film as the oil passes over the media. This process makes the water removal process much more efficient. The internal dispersion media is stainless steel and never needs to be changed.

 

Oil Filter Element

 

The outlet filter is equipped with a differential pressure indicator to alert the user when the element is ready to be changed. This indicator is calibrated to 30-40 PSID at which time the system will automatically shut down. Element change frequency can and will vary with every application and cannot be predicted effectively. However, the filter has be over sized by approximately six (6) times rated flow to maximize the life of the element under normal conditions.

 

It is suggested that the element be changed every six (6) months if no indication is shown during that time. The filter media can become fatigued and fail due to flow surges, heat, water, and pressure after continuous operation over a long period of time.

 

Vacuum Tower Air Inlet Filter

Metered outside air used to control the vacuum pressure inside the vacuum chamber, this air is cleaned using a filter/breather to remove particulates form the air as it enters the vacuum chamber. The element can be plugged within a very short period of time if larger amounts of air-borne contaminates are present. Under normal operating conditions and continuous operation, the air breather element will last approx 3-5 months before change out.

 

Vacuum Pump Coalescing Filter

The vacuum pump uses a coalescing outlet filter element to filter the exhaust air leaving the vacuum pump. The element is a cloth type with exterior metal canister attached to the discharge of the vacuum pump. To replace this element, expand and slide down the two spring retainers which are located on the outside of the coalescing element. Do the reverse process for installation of new cloth element.

 

Claw vacuum pump

The claw vacuum pump uses oil to lubricate the pump gears during operation. This oil can be seen from the oil sight plug located on the side of the claw vacuum pump. The sight plug should show the oil at ½ or in the middle position of the sight glass. The vacuum pump holds 10 oz of ISO VG 220 gear oil. The best choice would be synthetic oil and should be changed every 4-6 months or 20,000 hours of continuous operation whichever comes first.

 

The claw pump requires very little maintenance and is designed for high water ingression. When there is high water ingression and the unit is going to be stopped for extended periods of time, it is necessary to purge the claw vacuum chamber with air. This an easily be accomplished by opening the ball valve located on the side of the vacuum pump while it is running. This is done to remove any condensation that may otherwise remain trapped within the claw vacuum chamber. If the water is not removed from the claw chamber, then water can cause rusting of the vacuum chamber and claws.
