The Refining of Natural Gas - Bright Hub Engineering

The dehydrator removes the water moisture content from the gas by injection of glycol liquid into the stream. This is carried out in the glycol tower and as the glycol particles absorb the water they fall to the bottom, the dry gas rising to the top for the next process. The glycol is regenerated by boiling of the water which has a lower flash point, leaving the glycol for reuse. Amine tower

What Is Nitrogen Purging? - Procedure and Equipment Used

A cleaning component known as a "pig" is driven through the lumen of the equipment being cleaned using pressurized nitrogen gas. During the pigging procedure, the pig and gas pass through each pipe channel, purging the interior and removing gaseous and particulate impurities. Dilution Purging with Nitrogen Gas . Dilution purging involves combining gaseous nitrogen with the gas needed to be

Liquid Nitrogen Treatment. Medicine for warts and verucas

After a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off. The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn. Occasionally a blister (sometimes a 'blood blister') forms. If this happens, it is best to pop it with a clean pin and apply a plaster. New skin quickly forms
