Environmental pollution issues during oil extraction have always been the focus of social attention. Problems such as leakage, seepage, and volatile gas emissions may not only affect the production and life of surrounding residents but also pose potential threats to the regional ecological environment. Among numerous environmental remediation technologies, Sodium Persulfate has provided an effective technical path for addressing pollution caused by oil extraction due to its high efficiency and wide application range.

Ⅰ. Major Environmental Pollution Challenges Faced by Oil Extraction

Oil extraction covers multiple links including exploration, drilling, oil production, and gathering and transportation. Each link may become a pollution source, posing multi-dimensional challenges to soil, groundwater, and atmospheric environments.

Soil Pollution:

 Crude oil leakage or oily wastewater seepage may cause petroleum hydrocarbons to enter the soil. These substances adhere to soil particles, reducing soil permeability and water retention, altering its physical and chemical properties, and affecting soil ecological functions. Due to the slow natural degradation of such pollutants, they tend to persist in the environment for a long time, not only damaging land resources but also threatening groundwater safety through leaching.

Groundwater Pollution: 

This is a more concealed and long-term challenge. Chemical agents used in the extraction process and light components in petroleum may seep into aquifers through formation fractures or damaged well pipes. Once groundwater is polluted, remediation is difficult and time-consuming, directly endangering residents’ drinking water safety and the health of ecosystems.

Atmospheric Impact:

 Volatile organic compounds emitted during extraction and gathering and transportation are one of the key factors affecting regional air quality and triggering residents’ complaints.

These interrelated environmental challenges not only restrict the sustainable development of the oil extraction industry but also impose higher requirements for ecological environmental protection.

Ⅱ. Application Advantages of Sodium Persulfate in Oil Extraction Pollution Remediation

In response to the above pollution problems, Sodium Persulfate has demonstrated significant application potential. As a professional enterprise deeply engaged in Sodium Persulfate production, Fujian Zhanhua Chemical has always adhered to the core principle of "quality first, scenario adaptation" and established a strict full-process quality control system from raw material selection to finished product delivery. Its produced Sodium Persulfate has a purity of ≥99% and an active oxygen content of ≥6.65%, providing solid material support for the precise and efficient implementation of pollution remediation.

The core of Sodium Persulfate as an effective solution lies in its ability to be activated through various methods such as heat, alkali, and transition metals, generating highly oxidizing sulfate radicals to efficiently degrade petroleum-based organic pollutants.

Application in Soil Remediation

Inject or mix Sodium Persulfate (with activators if necessary) into contaminated soil. The generated sulfate radicals can effectively attack and oxidize the molecular chains of petroleum hydrocarbons adsorbed in the soil, converting them into carbon dioxide, water, or other low-toxicity small-molecule substances. This method can treat pollution at different depths, significantly reducing pollutant concentrations in the soil and creating conditions for restoring soil functions.

Application in Groundwater Remediation

Introduce Sodium Persulfate into the contaminated plume area through technologies such as injection wells or permeable reactive barriers. The radicals it generates can continuously act in groundwater, degrading dissolved petroleum pollutants and some chemical agents, effectively controlling the diffusion and migration of the contaminated plume, and laying a foundation for the long-term remediation of the groundwater environment.

Technical Characteristics

Sodium Persulfate boasts advantages such as relatively thorough reaction and a wide applicable pH range. Its final decomposition products (such as sulfates) are relatively environmentally friendly, with low secondary pollution risks. The technical scheme is relatively mature and easy to implement on-site in oilfields, providing enterprises with a practical and efficient pollution remediation option.

With the increasing environmental protection requirements, the application of Sodium Persulfate in oil extraction pollution remediation will continue to deepen. As a professional Sodium Persulfate manufacturer, Fujian Zhanhua Chemical is committed to providing high-purity, stable-performance Sodium Persulfate products for the environmental remediation field. Through a strict quality control system, the company ensures the stability of products between batches to meet the precise requirements for agent effectiveness in complex site remediation projects.
