Shale oil resources have proven to be quickly producible in large quantities and have recently revolutionized the oil and gas industry.The oil content in a shale oil formation includes free oil contained in pores and ...
Imbibition of water,as wetting phase in oil-wet fractured carbonate reservoirs,plays a key role in fluid flow between matrix and fracture system.The type of injected seawater and its chemistry would profoundly influen...
On January 8,2021,the largest in China continuous catalytic reforming(CCR)unit(with a capacity of 2.6 Mt/a)at SINOCHEM Quanzhou Petrochemical Company using the SINOPEC’s counter-current CCR technology with independen...

Bubble columns can be operated in semi-batch, co-current or counter-current mode. This study attempts to extend the dual-bubble-size (DBS) model, viz., the energy-minimization multi-scale (EMMS) model for gas-liquid s...
A computational fluid dynamics study of three-phase counter-current fluidization occurring in a turbu- lent contact absorber was performed. A two-dimensional, transient Eulerian multi-fluid model was used, in which th...
