PURGIT® flaring service for anhydrous ammonia and hydrocarbon gases

PURGIT has the equipment to safely degas ammonia tanks and pipelines. Using open or enclosed flares we burn vapors from anhydrous ammonia storage tanks, pipelines, rail cars, tank trucks, tank barges, ships, and various other pressure vessels.  Selection of the flare type is dependent on the gas burned. PURGIT has safely completed degassing and reconditioning on many ammonia tanks with capacities of 1 to 3 million cu/ft. We are experienced in this technique – lists and references available upon request.

Here are some photos of our equipment from past ammonia and LP jobs:

PURGIT VOC flareFlaring and degassing: Large pressure vessels and pipelines are usually degassed as part of routine maintenance so they can be opened for inspection. PURGIT has been tapped for many dozens of pressure vessel decommissioning and re-commissioning across the country. PURGIT has extensive experience with anhydrous ammonia. Re-commissioning: Once the tank inspection is completed, the tanks are filled with nitrogen gas to remove air and moisture. The tank can be tested at this time for leaks. Then liquid or gaseous cargo is introduced into the vessel to condition the tanks. The flaring continues until the nitrogen levels are low enough for the tank compressors to operate successfully.

 Burning ammonia and other gases with low heat value may require supplemental fuel. Natural gas or propane must be added to bring the BTU/ft3 up to proper levels for good combustion. PURGIT uses vaporizers like this one to supply the propane vapor necessary for the gas-assist flare to maintain compliance.
