The ,acid, recycling system is a fully modularized ,unit,. For installation, the pump on the ,acid, recycling ,unit, is plumbed to the working pickling tank(s) and a solenoid valve on the ,unit, is plumbed to a pressurized water source. The system uses 115 VAC/ 20 AMP service and, upon delivery, can be plugged in and immediately utilized.

The sour water ,stripping unit, is almost always located in the process area of the refinery and can be a single tower with no reflux or a single trayed tower with an overhead reflux stream. Other processes for treatment of sour water are: caustic/,acid neutralization,, caustic oxidization, and oil removal by settling.

Similarly, acid neutralization would remove a significant portion of the COD in the wastewater by stripping sulfides and mercaptans into the gas phase. However, this COD is not destroyed and will need to be sent to either an incinerator or a sulfur unit [1,4]. B-Results for Naphthenic and Cresylic Spent Caustic Naphthenic Acid Destruction:

Acid, springing is probably one of the oldest on-site treatment methods used in refineries to dispose of spent caustic. ,Acid, springing works by adding a strong ,acid, (e.g., sulfuric ,acid,) to the spent caustic until the pH is around 3. At this low pH, the ,acid, oil tends to dissociate from the aqueous phase to form a separate floating “oil” layer.

There are three distinct processing steps in the sour water stripping process: degasification, hydrogen (acid-gas) stripping and ammonia stripping. Figure 1 shows only one stripper column. During the degasification stage the sour water feed from the plant is cooled and fed to a degasser where dissolved hydrogen, methane and other light hydrocarbons are removed.
