Prior art description For many years it has been the common practice. To join pipe sections, process instrumentation, and or numerous forms and types of valves (i.e. automated control valves, manual control valves, check valves, block valves manual and or automated, and or manual throttling valves, and or pressure safety valves) together with threaded or welded connections and or with opposing spaced annular flanges which extend radial from the pipe section and or the instrument and or the numerous forms and types of valves, at each end. Then fastening the sections of pipe, process instrument, and or numerous forms and types of valves, together using a plurality of bolts or fasteners in a mechanical bolting system. A
2o sealing gasket of suitable composition and configuration is interposed between such flanges to contain pressure tightly the solid, the liquid, or the gas within the piping system.
The flanges are then torque to a specification tightness, as to compress the sealing gasket material, thus completing the connection pressure tightly.
Many piping systems so constructed are intended to carry hydrocarbons and or toxic chemicals, and or corrosive chemicals, and or nuclear exposed gas, and or liquid, and or solid products under high pressure. Experience and Engineering Principles and Alberta Environmental Protection Legislation has proven that a gasket interposed between two spaced annular opposing flanges will leak the 3o contents of the piping system, to the atmosphere at a molecular level.
There is uncontrolled molecular level leakage at the spaced annular opposing flanged connections which extend radial from the pipe, and or instrument, and or numerous forms and types of valves.
The leakage occurs through and or across the sealing gasket material. The amount of leakage is a factor of ~ The pressure of the material contained within the piping system.
~ The temperature of the material contained within the piping system.
~ The molecular composition of the material, contained within the piping system.
to ~ The sealing gasket material of construction ~ The surface area contact of the sealing gasket (taken as the diameter of the pipe).
~ The specification torque applied to the sealing gasket as defined by the flange pressure rating These are six of the contributing factors which cause Fugitive Emissions.
The problem with devices and systems in the market today is the failure to deal with the mechanical fastening system of the common welded or threaded flange connection used extensively in industry today. The common bolt (stud) used in 2o the mechanical fastening system all have the potential to leak through the hole through which the bolt passes, when only the outer diameter or circumference of the flange is covered in an attempt to contain a sealing gasket failure or simply detect large and or small concentration leaks.
By simply wrapping the outside circumference of the flange in an attempt to contain leaks, the plurality of bolts (studs) used in the mechanical fastening system begin to leak between the bolt and the bolt hole. The leak is not contained in a manner that all material could be recycled in a purer form isolated from the atmosphere, back to the process of origin for reclaim, or to a system for absorption, adsorption, analysis or destruction Each of these researched devices and systems fails in the attempt to contain leakage at the molecular level through or across the sealing gasket material interposed between two spaced annular flanges. These devices or systems fail to address the leaking ability, of the plurality of bolts (studs) used in the mechanical fastening system, by failing to enclose the mechanical fastening system and sealing the complete connection including the welded or screwed connections before and after the flanges, the flanges, the sealing gasket, and the mechanical fastening system in an enclosure which attaches pressure tightly to the pipe system.
to For example: Canadian Patent #1178629 discloses a flange safety shield which is shrink wrapped to the flange exposing the flange connection and the mechanical bolting system consisting of a plurality of bolts or fasteners. The objective of this device is to contain the leak between the flanges without a concern for the leak potential of the plurality of fasteners (bolts) connecting the flanges together.
For example: Canadian Patent #1308043 discloses a flange clamping and injection device used for on line leak sealing of flanges and piping using a curing agent injection, of sealing compound encased within the clamp/ injection device.
The objective of this device is to fill any cavity formed by the flanged piping system connection, with the sealing fluid which is pumped into the clamping /
2o injection device under pressure. The flange must then be cut out at the earliest convenient maintenance activity. This is a form of destructive leak seal technology.
For example Canadian Patent #1161697 discloses a clamp which uses a bladder inside the clamp to contain and identify the leaking connection by a change in pressure of the space between the clamp and the leaking connection. A
suspicion of a leak, clamping the suspect leak, then waiting for a change in pressure to verify the leak is required to make efficient use of this device.
For example United States Patent #W009616321 discloses a fugitive emission detection system which uses a clamping system attached to the outside 3o circumference of the flange with sensing devices placed directly above in the closest proximity possible to the potential leak. The plurality of fasteners used to connect the flanges is exposed with no concern for the leaking ability of each of these fasteners between the fastener and the hole through which the fastener passes.

A one-line system and instrument drawing representing a piping system 1 with a plurality of flanged connections 2. Fugitive emission capture devices 3 are connected pressure tightly to the piping system 1 to eliminate the loss of containment due to improperly installed flanged connections 2. Instrumentation to detect a pressure change in the fugitive emission capture devices 3 will indicate a leak at that flanged connection. Hose connections S are used to connect temporary piping system 7 to a portable storage tank 6.
Drawings #8 and #9 are a combination of the drawings for claims #8 and #9 3o referring to claims #8 and #9 and drawing #1 as the represented Fugitive Emission Capture Device.
A one-line system and instrument drawing representing a under ground 6 pressure piping system 1 with a plurality of flanged connections 2. Fugitive emission capture devices 3 are connected pressure tightly to the piping system 1 to capture in pure form the fugitive emissions, that a sensing element 7 connected to a programmable remote communication system 5 connected through a below grade 6 PVC under ground conduit 4, will alarm to a control center.
Drawing #12 refers to claim #12 and drawing #1 as the represented Fugitive Emission Capture Device.
to A one-line system and instrument drawing representing a pressure piping system 1 with a plurality of flanged connections 2. Fugitive emission capture devices are connected pressure tightly to the piping system 1 to capture in pure form the fugitive emissions, using a compatible inert carrier gas 4 as a mode of force, kept at pressure by pressure control valve 5 and pressure transmitter 6. A
programmable logic controller 7 opens and closes valves 9, 10, 11 in a timed sequence to allow carrier gas 4 to flow through a molecular concentration analyzer 8. Analyzer out put is to a data logging system 12.
