CO2 FLASH VAPORIZER

SAMPLING EQUIPMENT
LCO2 Flash Vaporizer Unit: This electrically heated, flash-vaporizer / pressure regulating (VPR) device is first to be connected to a storage tank or other sample sources’ liquid phase outlet valve. The purpose of a VPR is to flash-vaporize LCO2 and its impurities into a homo-geneous phase and then send a representative gaseous sample to a gas wash bottle , container or to purity tester at a controlled delivery pressure (ex. 20 – 40 psig [136 – 252 kPag]) for efficient flushing and filling. An outlet port needle valve is also installed for convenient sampling operations .

Here are other alternatives to the use of a CO2 vaporizer, although they might be more limited depending on the needs of each company and the intended applications for the device. On the one hand, ambient vaporizers can fulfil similar tasks to a CO2 vaporizer, although these solutions are limited to -28ºC.
