What are the hazards and disposal methods of oil sludge?

Industry News / Chat online / Give me a price / Jan 15, 2020

In the process of oil production, storage and transportation, refining and processing and use, oil will spill and discharge due to accidents, abnormal operations and maintenance. Crude oil spills, if not properly handled, it can pollute the environment (The mainly is soil and groundwater).

After crude oil enters the soil and underground water, the harm produced is mainly reflected in the following aspects:

1. Affect soil permeability and reduce soil quality.

2. It obstructs the respiration and absorption of plant roots, causes root rot, and affects the root growth of crops.

3. Reduce the reasonable content of phosphorus and nitrogen in the soil and affect the nutrient absorption of crops.

4. Polycyclic aromatic hydrocarbons in petroleum have carcinogenic, teratogenic and mutation-causing effects, which can accumulate in animals and plants through the food chain step by step, endangering human health.

According to the soil and water content of the contaminated soil, the oil sludge formed has two states, including solid block oil sludge and liquid oil sludge, which can be removed or reprocessed by intercepting engineering measures.

Oil sludge treatment method

1. Biological treatment methods

This methods can be divided into three categories: a. Tillage method; b. Composting method; c. Biological sludge reactor.

2. Curing treatment method

The curing agent, coagulant and other chemicals of a certain component are added to the oily sludge, and after some chemical reactions occur, they form a solid block solid for stacking, storage and treatment;

3. Desiccation and incineration treatment

The oil sludge shall be dehydrated by mechanical equipment, and then the oil-containing sludge after desiccation treatment shall be sent to a combustion chamber for combustion, and the sludge residue after combustion shall be discharged.

4. Pyrolysis treatment method

Pyrolysis treatment principle is that oil sludge is pyrolyzed at high temperature in the pyrolysis reactor in the absence of oxygen, and then the oil gas produced are cooled with the condensing system to obtain liquid oil.
