Role of Polyaluminum Chloride in Oilfield Wastewater Treatment

Polyaluminum chloride has become an important agent in oilfield wastewater treatment in recent years. It is a new type of coagulant with strong coagulability, rapid demulsification, fast sedimentation, small floc volume, and the same effect under alkaline and neutral conditions, which is the direction of water treatment agent developers. Polyaluminum chloride, polyaluminum ferric chloride and polyacrylamide are the key agents for the treatment of oilfield sewage.

The desulfurization effect of polyaluminum chloride in oilfield wastewater treatment is obvious. A large number of sulfur ions in oilfield wastewater not only do great harm to the surrounding environment, but also induce local corrosion and stress corrosion cracking of metal equipment. The desulfurization effect of polyaluminum chloride used in oilfield wastewater treatment was studied. Polyaluminum chloride has wide pH range, low cost and good safety. The electrochemical method is used to oxidize sulfur ions as sulfur elements, and then polyaluminum chloride is used as flocculant to desulfurize oilfield sewage.

The so-called oily sewage mainly refers to the pollutants produced by petrochemical enterprises in the process of exploitation. If the oily sludge is directly discharged due to improper treatment, it will not only directly affect the soil and groundwater resources, but also be a huge waste of our scarce oil resources.

It is found that polyaluminum chloride has a long molecular chain, which can bridge the colloidal particles formed by coagulation to form a large and tough floc, thus improving the performance of the floc. The composite application of polyaluminum chloride and polyacrylamide can improve the treatment effect.

If the oily sludge wastewater with harmful substances and high oil content is treated with a certain recovery technology, a considerable amount of waste oil in the oily sludge can be recovered, and the treated sewage sludge can meet the national discharge standards to prevent secondary pollution.
