Hazardous material liquid dispensing system and method |
摘要 |
A non-venting hazardous material liquid dispensing system (25) includes a removable supply vessel (7) coupled to a gas source (1) and a permanent buffer vessel (11). The permanent buffer vessel (11) is additionally coupled through a suction pump (14) to the removable supply vessel (7). The suction pump (14) suctions pressure off the permanent supply vessel (11), transferring the pressure to removable supply vessel (7). The transfer of pressure causes hazardous material liquid (34) to be drawn from the removable supply vessel (7) into permanent buffer vessel (11). The permanent buffer vessel (11) dispenses hazardous material liquid (34) to a process tool.
