Apparatus for analytical sampling and/or conditioning of a process gas with selective isolation capability, and method therefore

The method of monitoring or treating a fluid, comprising the steps of:

• a. providing a quill having a receiver to receive a cartridge;
• b. mounting said quill to a fluid passage;
• c. mounting said cartridge to said receiver of said quill;
• d. allowing fluid from said fluid passage to engage said cartridge;
• e. mounting a tool to an isolation device in fluid impermeable fashion, said isolation device formed to selectively provide access to said quill;
• f. opening said isolation device;
• g. deploying an extension from said tool through said isolation device and into said quill so as to engage said cartridge therein;
• h. using said extension to disengage said cartridge from said quill;
• i. retrieving said extension with cartridge from said quill, and through said open isolation device;
• j. closing said isolation device;
• and
• k. accessing said cartridge therein.

A fluid conditioning or monitoring system, comprising:

• a quill, comprising:
• a body having a length having first and second ends and a passageway therethrough;
• a receiver formed within said passageway;
• said first end of said quill in fluid communication with an isolation device;
• a cartridge formed to removeably engage said receiver of said quill, said cartridge having first and second ends, said second end being open;
• a component having first and second ends, said component mounted to said cartridge;
• wherein, upon engaging a tool to said isolation device and opening same, said tool passes through said isolation device to said cartridge, to engage and remove said cartridge with said component from said quill, via said isolation device while under pressure.

The method of installing a component in a quill in a pressure zone, comprising the steps of:

• a. providing a receiver in said quill;
• b. providing an isolation device in communication with said quill;
• c. closing said isolation device;
• d. providing a tool having a body containing a component;
• e. mounting said body of said tool to said isolation device;
• f. opening said isolation device, while using said body to contain any pressure within said isolation device;
• g. using said tool to reposition said component out of said body, through said open isolation device, and into said quill;
• h. using said tool to removeably engage said component to said receiver in said quill;
• i. detaching said tool from said component and withdrawing same from said receiver and said isolation device;
• and
• j. allowing fluid to enter said component via said quill.

An insertion tool, comprising:

• a body having first and second ends and a passage therebetween, said first end comprising a threaded opening having a cavity formed therein to receive a cartridge;
• an insertion rod having first and second ends, said insertion rod longitudinally engaging said passage formed in said body, said insertion rod having a longitudinal passage therethrough, said second end of said insertion rod having formed therein a receiver having walls forming a profile;
• a control rod having first and second ends, said control rod having a length situated in said longitudinal passage of said insertion rod, said second end of said control rod having a drive member having a profile formed to slidingly engage a socket at an end of said cartridge;
• whereby, upon engaging said threaded opening of said body to an isolation device and opening said isolation device, said second end of said insertion rod is formed to pass through said isolation device to insert or remove a cartridge upstream said isolation device under pressure.

A fluid conditioning or monitoring system, comprising:

• a quill, comprising:
• a body having a length having first and second ends and a passageway therethrough;
• a receiver;
• a cartridge formed to removeably engage said receiver of said quill, said cartridge having first and second ends, said first end having a connector formed to engage a tool, said second end formed to engage a pressurized fluid;
• wherein, upon engaging a tool to said isolation device and opening said isolation device, an extension associated with said tool is formed to pass through said isolation device to said cartridge in said quill, to engage via said connector of said cartridge to remove same from said quill and isolation device while under pressure.
