International Classification:

H01J 1/62

US Classification:

313493000

Abstract:

A system and apparatus for manufacturing a low vapor pressure vapor stream lean in low volatility contaminants, and delivering same to a point of use. The system provides a transport vessel having a liquid phase or two-phase fluid held therein. The liquid and/or two-phase is transferred from said transport vessel to a vaporization vessel, wherein at least part of the liquid is vaporized. A liquid stream that is enriched in low volatility contaminants is withdrawn from the vaporization vessel, and a stream that is lean in low volatility contaminants is withdrawn from the vaporization vessel. The low vapor pressure stream is delivered to a point of use and the purity is maintained within a desired range.

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.
