US Patent:

20080078447, Apr 3, 2008
Filed:

Sep 29, 2006
Appl. No.:

11/540220
Inventors:

Christos Sarigiannidis - Williamsville NY, US
Thomas John Bergman - Clarence Center NY, US
Michael Clinton Johnson - Grand Island NY, US
Shrikar Chakravarti - East Amherst NY, US
International Classification:

E03B 1/00
H05B 3/02
H05B 1/02
US Classification:

137 12, 219486, 219497
Abstract:

Systems, apparatuses and methods for vapor phase fluid delivery to a desired end use are provided, wherein the conditions of the system are monitored to determine when the water concentration or supply vessel surface temperature exceeds a specified value or when the low vapor pressure fluid pressure falls below a specified value for the purpose of removing a first supply vessel from service by discontinuing vapor flow from the first supply vessel and initiating vapor flow from a second supply vessel.

International Classification:

H05B 3/06
H05B 3/20
F17C 13/00
F17C 7/04
US Classification:

219535, 219536, 219521, 62 481
Abstract:

A system for delivering vapor phase fluid at an elevated pressure from a transport vessel containing liquefied or two-phase fluid is provided. The system includes: (a) a transport vessel positioned in a substantially horizontal position; (b) one or more energy delivery devices disposed on the lower portion of the transport vessel wherein the energy delivery devices include a heating means and a thermally conductive non-adhesive layer disposed therebetween to the gaps and provide substantially uniform energy to the transport vessel.

International Classification:

F15D 1/00
US Classification:

137 14
Abstract:

Systems, apparatuses and methods for vapor phase fluid delivery to a desired end use are provided, wherein the conditions of the system are monitored to determine when the water concentration or supply vessel surface temperature exceeds a specified value or when the low vapor pressure fluid pressure falls below a specified value for the purpose of removing a first supply vessel from service by discontinuing vapor flow from the first supply vessel and initiating vapor flow from a second supply vessel.

US Patent:

20110225986, Sep 22, 2011
Filed:

Mar 22, 2010
Appl. No.:

12/728604
Inventors:

Justin Cole Germond - Amherst NY, US
Kenneth Leroy Burgers - E. Amherst NY, US
Christos Sarigiannidis - Williamsville NY, US
Michael Dennis McCain - Williamsville NY, US
Keith Randall Pace - E. Amherst NY, US
Heng Zhu - Tonawanda NY, US
Hisham E. Falah - Buffalo NY, US
International Classification:

F17C 9/02
F17C 13/08
US Classification:

62 502, 62 532
Abstract:

This invention relates to gas vaporization and supply system that includes (a) a vessel suitable for holding a bulk quantity of a liquefied gas; (b) at least one heating source positioned on or near the vessel to supply energy to, or remove energy from, the liquefied gas; and (c) a heating source controller adapted to use process variables feedback for dynamically regulating the heating source and maintaining and regulating gas output. The process variables feedback results from cascading sequence control of at least two process variables. The process variables include pressure, temperature, and/or gas output flow rate. This invention also relates to a method for delivery of a gas, e.g., ultra high purity gases, from a liquefied state in a controlled manner to a usage site, e.g., a semiconductor manufacturing facility. This invention provides faster heating system response to fluctuations in customer demand, a longer heater life, and improved reliability.
