Abstract
A cold trap for condensing and polymerizing residual vapor. The cold trap comprises a containment vessel which comprises a vertical sidewall defining a cylindrical inner surface of substantially constant diameter. Fluidly connected to the sidewall is a vapor inlet line which enters the containment vessel tangentially at a point near the top end thereof such that the vapor entering the containment vessel through the vapor inlet line will impinge against the inner surface of the sidewall and flow in a generally rotational pattern within the containment vessel. The cold trap further comprises a cooling member which is positioned within the containment vessel for facilitating the condensation and polymerization of the vapor.
Claims9
A cold trap for condensing and polymerizing residual vapor, said cold trap comprising:
- a containment vessel having top and bottom ends;
- a vapor inlet line fluidly connected to and entering said containment vessel tangentially at a point near the top end thereof and a vapor outlet line fluidly connected to and exiting the containment vessel tangentially at a point near the bottom end thereof such that the vapor entering the containment vessel through the vapor inlet line and exiting the containment vessel through the vapor outlet line will flow in a generally rotational pattern within the containment vessel;
- and
- a cooling member positioned within said containment vessel for facilitating the condensation and polymerization of the vapor.
A cold trap for condensing and polymerizing residual vapor, said cold trap comprising:
- a containment vessel comprising a vertical sidewall defining a cylindrical inner surface of substantially constant diameter;
- a vapor inlet line disposed horizontally tangential to the sidewall and extending therethrough such that vapor passing through said vapor inlet line will enter said containment vessel in an initially horizontal vector and will subsequently impinge against the inner surface of the sidewall causing the vapor to flow in a generally rotational pattern within said containment vessel;
- a vapor outlet line disposed horizontally tangential to the sidewall and extending therethrouqh;
- and
- a cooling member positioned within said containment vessel for facilitating the condensation and polymerization of the vapor.
A cold trap for condensing and polymerizing residual vapor, said cold trap comprising:
- a containment vessel;
- a vapor inlet line fluidly connected to and tangentially entering said containment vessel and a vapor outlet line fluidly connected to and tangentially exiting the containment vessel such that the vapor entering the containment vessel through the vapor inlet line and exiting the containment vessel through the vapor outlet line will flow in a generally rotational pattern within the containment vessel;
- and
- a cooling member positioned within said containment vessel for facilitating the condensation and polymerization of the vapor.
