Application of silicon carbide film in petrochemical field

First, ultra-fine water treatment in oil and gas fields

The silicon carbide ceramic membrane integrated system is used to treat oily sewage in oil and gas fields, and qualified reinjection water is obtained at one time (reaching the A grade index in SY/T5329-2012 standard). With the continuous development of oil and gas fields, the water quality of produced water is becoming more and more complex, the difficulty of treatment is increasing, the traditional backwash filter is prone to filter material hardening, incomplete filter material cleaning, unqualified effluent, short life, large footprint and other problems, and silicon carbide ceramic membrane system adopts "cross-flow" filtration method, with high filtration accuracy, short process, small footprint, high integration, stable effluent and other characteristics, confirmed by on-site pilot tests and engineering cases, its impact on water flooding, polymer flooding, The ternary composite flooding produced water has good treatment effect. Application fields: (<>) oilfield produced water (<>) fracturing backflow fluid (<>) drilling waste liquid (<>) gas field produced water.

Second, the conventional water flooding of oilfield produces sewage film treatment

Conventional water flooding technology is widely used in China's onshore oilfields and offshore oilfields, and the water injection quality directly affects the development effect of oilfields for low-permeability and ultra-low-permeability reservoirs. The silicon carbide ceramic membrane process is used to finely treat the water-flooded oily sewage, and the effluent quality reaches the A standard.

Third, oilfield containing poly/ternary composite sewage membrane treatment

Due to the very complex composition of polysewage containing water, with high viscosity, high degree of emulsification, complex composition and difficult biodegradation, traditional processes cannot meet the needs of oilfield production. When the poly-containing sewage is treated by the combination process of pretreatment + silicon carbide ceramic membrane, the oil and particle suspended solids in the polysewage are removed in one step to meet the water injection requirements of low-permeability oilfield.

Characteristics of silicon carbide ceramic membrane treatment process:

(1) High quality of filtered water quality (2) Save land occupation (3) Save operating costs (4) Long life (5) Simple operation
