Abstract
Disclosed herein is an apparatus for supplying a liquefied chemical gas comprising a vaporizer disposed within a fabrication plant, the vaporizer adapted to receive the liquefied chemical gas and output a vaporized chemical gas, a purge vessel connected to and in fluid communication with the vaporizer, and wherein the vaporizer is adapted to purge a volume of the liquefied chemical gas and the purge vessel is adapted to receive the volume of liquefied chemical gas. Other embodiments and methods are described herein.
Claims22
An apparatus for supplying a liquefied chemical gas comprising:
- a vaporizer disposed within a fabrication plant, the vaporizer adapted to receive the liquefied chemical gas and output a vaporized chemical gas;
- a purge vessel connected to and in fluid communication with the vaporizer;
- and
- wherein the vaporizer is adapted to purge a volume of the liquefied chemical gas and the purge vessel is adapted to receive the volume of liquefied chemical gas.
An apparatus for purging a liquefied chemical gas from a vaporizer comprising:
- a vaporizer having a contaminated liquefied chemical gas and a vaporized chemical gas;
- a purge vessel in fluid communication with the contaminated liquefied chemical gas;
- and
- means for purging the contaminated liquefied chemical gas from the vaporizer to the purge vessel.
An apparatus for purging a liquefied chemical gas comprising:
- a ton vessel disposed apart from a fabrication plant, the ton vessel including a liquefied chemical gas and a heater, the ton vessel in fluid communication with a vaporizer disposed within the fabrication plant;
- a purge vessel connected to and in fluid communication with the ton vessel;
- and
- wherein the ton vessel is adapted to purge a volume of the liquefied chemical gas and the purge vessel is adapted to receive the volume of liquefied chemical gas.
A method of purging a liquefied chemical gas comprising:
- supplying a liquefied chemical gas to a vaporizer disposed within a fabrication plant;
- vaporizing the liquefied chemical gas in the vaporizer;
- operating the vaporizer for a period of time;
- and
- purging any contaminated liquefied chemical gas from the vaporizer to a purge vessel.
