During maintenance shutdowns or regular inspections related to PED regulations (pressure equipment), companies using anhydrous ammonia wish to empty and inert their devices, which typically contain 4 to 20 tons of ammonia products. CURIUM uses its validated method - using an ATEX compressor to transfer the liquefied phase of ammonia and then recover the gas phase without emitting any gas into the atmosphere. The transfer flow rate is 150 cubic meters per hour. This operation greatly limits the amount of waste generated - only producing very little or no alkaline waste. Then fill the device with gas for inerting.
