■ Brief Introduction
Oil and gas environmental industry is a category of oil & gas field technical service industry. Based on the 17 years’ practice in O&G area, Jereh EMG can provide integrated solution of oily waste treatment.
We differentiate the oily waste types, and propose an economical and efficient treatment plan accordingly for customers:
•Oil-base Drilling Mud and Oily Cuttings
•Refinery Oily Sludge
•Oil Sludge Pit
•Tank Bottom Sludge
•Produced Oilfield Water
The solutions can also create more added value for customers, with the realization of waste reduction, hazard-free treatment and recycling.
■ The main technical
Thermal Desorption Technology
It is capable of treating various materials, including oil-base drilling mud and oily cuttings, sludge of oil separator, oil scum and waste activated sludge, sludge pits, heavy oily sludge and tank bottom sludge.
Indirect Fired Thermal Desorption Technical Process
Direct Fired Thermal Desorption Technical Process
Conditioning & Separation technology
It is mainly used for recycling lighter emulsified oily sludge and waste oil. Oily sludge is conditioned by chemical conditioning and mechanical centrifugation method. The oil is removed from the surface of the solid waste by adding chemical agent. Then oil, water and solids are separated by centrifugation. After treatment, the solid can meet customer’s processing standards while recovered oil can be used for sales and separated water can meet the requirements into the sewage treatment plant.
Fracturing Flow-back Fluid Reuse Technology
It deals with the flow-back fluid produced by gel fracturing, slickwater fracturing and linear gel fracturing, and can achieve targeted removal of contaminants, such as hardness of ions, petroleum, suspended solids and boron, etc. The treated flow back can be reused for fracturing fluid mixing, which is good for reducing the fracturing cost and environmental pollution.
Fracturing Flow-back Fluid Reuse Technical Process
Ex-Situ Pile Thermal Desorption technology
It is used for the treatment of contaminated soil by volatile, semi-volatile and less-volatile organic contaminants such as petroleum hydrocarbons, pesticides, polychlorinated biphenyls etc. It is applicable when the polluted soil is already excavated or surface soil is contaminated, which can avoid the long-distance transportation of contaminants.
Ex-situ Pile Thermal Desorption Technical Process
Ecopile technology is mainly used for the treatment of petroleum hydrocarbons and other biodegradable organic contaminated soil, sludge. The bioremediation technology adopts the principles of biostimulation, biofortification, natural attenuation, bio-phytoremediation. It includes by the addition of nutrients to stimulate the growth of indigenous organic matter degradation flora and by adding organic matter degradation flora to strength remediation. It also can realize loose soil and plant rhizosphere remediation through the growth of plant roots.
