Abstract

The Plant fluids in Oil Refineries, Petrochemicals, Power and Gas Plants are treated by permanent Magnet installed inside large Piping units (Mechanical Piping Spool), by change of fluid physical property. The Plant Pipe line must be cut to accommodate installation. Using of Piping Magnetic units is to clean the Pipe line scales, softening the water, and save Energy of burning Gases like Natural gas by 20-30% . The conventional units use big lengths piping with diameters corresponding to Pipe sizes, which is costly for Installation. My Patent the "Magneto Orifice Plate" - (MOP) uses the same principal of Magnetic treatment with low cost and use 1.50" inch total length for all Plant Pipe sizes installations, easy , Safe and has same functions of the large Magnetic unit.

Description

Date: July 01.2013 "Detail Description Of The Patent Magneto Orifice Plate (MOP) & Magneto Space Plate (MSP).
1. Introduction Magnetic effect on water:
For more than 35 years, magnetic treatment of water has been proven to reduce "hardness" caused primarily by calcium and magnesium. Water treatment can prevent deposits of these minerals on the inside of pipe walls, as well as existing build up of solids.
Water molecules are made up hydrogen and oxygen atoms and their respective electron orbits. When the water is exposed to a magnetic field, the chemical and physical interaction that takes place between electrical charges and water molecules can cause certain atoms to lose their electrons. When this happens, atoms become ionized or charged because of the missing electrons. As a result, these atoms will attempt to regain their missing electrons. The combination of ionized atoms and magnetic fields causes an electrical current to form in the water. FIG.-01B, TAB.4 In effect, the electrical charges that sustain a magnetic field are carried by the hydrogen ions contained in the water. As a result, high concentrations of acid in water make for a stronger magnetic field.
When a Water or any other fluid moves through a strong Magnetic Field of flux, an excitation occurs in the conductive dissolved solids, which cause expel a free electron or absorb a free electron to satisfy the unbalance condition, as a result the atom have less ability to bond each other ionically, which change the physical property of the water, an example of high bonding (high physical) in solid crystal ice and low bonding (low physical) soft snow flakes, therefore the scale accumulation on the surface of the inside diameter of the water pipe lines used in Oil Refineries and Power plant which act to reduce the inner pipe diameter by accumulation of scales around the inside pipe diameter will change its physical property, the hard scale deposit change to a soft deposit with smooth consistency as butter, and the abrasion of passing fluid abrades this soft material and carry it away because the original bond of the scales can not resist the impact of the unbalanced condition and washed away by the passing fluid.

The conventional (MSU) type shown in FIG.01B TAB4 are widely used in Industry and had approved good Performance for water treatment and Energy saving. The new welded flanges used for installation should be Hydraulically tested or X-Rayed to check possibility of fluid leak after welding. It has been found and approved that using the MSU on Burning Gases such as Propane Gas, Butane, Natural Gas, or Diesel fuel, that these fluids can also be magnetically treated, a physical and Chemical change in gas property can make saving of Millions of Dollars of burning gases in Industrial Burners.
(TAB.05: "Fuel Saver").

2. Orifice Plates in Oil Refineries, Petrochemical and Power Plants Orifice plate is a metal plate with a hole in the middle used since beginning for measurements in Oil Refineries, Petrochemicals, Power plants to measure the flow rate of fluids streams in pipe lines. The suitable bore diameter (d) of the orifice plate to measure the fluid flow is simply calculated as follows:
Where:
B = Beta ratio, d= orifice bore diameter, and D= Pipe line diameter =

3 The best value of "Beta ratio" selected to determine the orifice plate bore diameter, differential pressure of fluid for flow measurement and Max. Flow rate passing through the orifice is between (0.5- 0.75).
Higher Beta ratio, means bigger size bore diameter and consequently higher flow rate passing through the orifice. As the fluid approaches the orifice the pressure increases slightly and then drops suddenly as the orifice is passed.
It continues to drop until the "vena contracta" is reached and then gradually increases until at approximately 5 to 8 pipe diameters.
Reference:
(FUNDAMENTALS OF ORIFICE METERING) by SMITH Metering, Inc.
(EMERSON PROCESS MANAGEMENT-DANIEL FLOW MEASURMENTS) In my application, the Paddle Orifice Plate is used as a "Holder" to the Magnetic Bar Assembly with a bore diameter calculated wider than the Flow Orifice Plate bore diameter to avoid sonic velocity or chock flow at the orifice plate due to restriction on System Fluid Process Pressure and flow.
3. The Patent My design for new device is made to provide and make benefit of this useful existing Technology in Industry easy and more practical for installation in the Plants. The new devices for water and Gas treatment, the "Magneto Orifice Plate"- MOP or "Magneto Steel Spacer"- MSP are designed to provide same operation and functions of the conventional types which have lengths of Approx. 1.5- 6 feet (450 - 2000mm) , But with limited reduced length of 20 -22mm. to Max. 25mm. (0.78 - 0.86 to Max. 0.98 inch) for all pipe lines sizes installations in the plant.
The Design and fabrication is done in either option:
A- By using Paddle Orifice Plate - MOP (Magneto Orifice Plate) B- By using Paddle Steel Spacer - MSP (Magneto Space Plate) A- Using Paddle Orifice Plate:
316 Stainless Steel Rings (Appendix-FIG.06-1&2) are fabricated to accommodate the Magnetic bars, the Orifice plate bore circumference surface is welded with the mid. Width/distance of the ring, i.e. 11.0mm. from each side

4 of the ring. The Ring is Designed so that its outside diameter is less than the pipe line inside diameter by 8.0 mm each side to provide free insertion of the Ring into the pipe line inside diameter. This distance of 8mm. has no significant effect on Process condition, specially the process pressure normally recovered after 5 - 8 pipe diameter when Beta ratio is below 0.75, while selected Beta ratio is beyond this figure.
FIG-02 TAB 6: are the Dimensions of pipes inside and outside diameters FIG.-04B01&02, TAB 7 : are detailed dimensions of MOP rings FIG.-05A & B TAB 8: example of the strength of MOP structure FIG.-6 TAB 10: are Flanges & Pipes Dimensions FIG.-7 TAB.10 : peddle type Orifice Plates dimensions for different pipe sizes.
FIG.-08B, FIG.-09B, FIG.-09C,FIG.-09D&E TAB11: are drawings of MOP for different pipe line sizes.
Welding points of the ring with the orifice late is smoothed to secure smooth insertion of the Ring into the inside pipe diameter.
The MOP shall not be installed on pumps discharge or in Ring type Joint (RTJ) flanges because of the Metal ring gasket.
The type of Magnet used is Rare Earth permanent Magnet Neodymium Grade N52, with average flux density of each Magnetic Bar 11,000 - 12,000 Gauss, referred to as NdFeB magnets, or NIB, composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). Strength of the Magnet flux density depend on the material of the Magnet type. The magnetic field axially act on the fluid flow is affected by the process service temperature and thickness of the 304 Stainless Steel Bar tube, lower temperature and thickness of the tube, better strength of the flux, while it is directly proportional with the size of the Magnet to be used, e.g. Neodymium-N52 Magnet piece of 16mm. diameter X6.35mm length (5/8"X1/4") has a "Residual flux density" of 14,800. Gauss.
(Ref. K&J Magnetic products data web site).
The Steel Bar tube thickness is (0.3- 0.6mm), (0.01" - 0.023"). Selection of high flux density type Magnet such as Neodymium N40, N45, N50, or similar depend largely on fluid Service condition, Impurity degree of the water in ppm., and fluid temperature.
B- By using Paddle Steel Spacer - MSP
The Magnetic device is designed and fabricated by using Paddle Stainless Steel Spacer as a "Holder" to the Magnetic assembly of the device.
Spectacle Blind or Peddle Blind plates are inserted into the flange to blank off the process line for Maintenance. A paddle Spacer is inserted , filling the gap between the flanges created by the Paddle Blind allowing the Process fluid to flow through the line.
(Appendix FIG.07) :Spectacle Blinds and Paddle Spacers.
(Appendix FIG.08) :Dimensional drawing of Paddle Spacers.
The bore diameter of the Paddle Spacer for the application is fabricated with same pipe line inside diameter, which need no calculation for Orifice plate bore diameter, and straight forward installation with the pipe flange, The 316 Stainless steel Paddle Spacer is fabricated to ASTM. A516, with a plate width/thickness of 20-22mm. or Max. 25mm. (0.78 - 0.86 or Max. 0.98 inch) which is the Maximum width of the Magnetic device.
The Spacer with this width/thickness of the plate is used to accommodate the Magnetic Bars shown in the Ring (Appendix- FIG. 06-1) by welding the two Steel supporting strips ends of the Magnetic bars Assembly with the Paddle Spacer inside bore's circumference.
Insertion of Spectacle blinds or Paddle Spacers into the RF. Flanges are normally done by pipe fitter's simple tools or by flange spreader.
New ISO approved tools had been introduced , one of these is The EqualizerTM Secure-Grip Flange Spreader safest, and most innovative flange spreading tools available which meet the requirements of ISO 9001-2008, uses unique patented expanding collet technology for Spreading ANSI, DIN, SPO, ASME, API, and other flanges, (Appendix FIG.-03) : EqualizerTm Grip Hydraulic Flange Spreader.
