7, rhamnolipid was capable of fully emulsifying the light crude oil up to the 5th cycle performed (it is very likely that it will be able to undergo many more cycles). Additionally, the crude oil can be fully recovered within 1 h of H2SO4 addition in each cycle. This performance ...

This paper aims to analyse the scientific production that deals with the study of groundwater’s Life Cycle Assessment (LCA), using bibliometric methods. Thus, it contributes to the evolution of knowledge of this resource in terms of its use (environmental, economic and social). The ...
The groundwater enters a vicious cycle and water level will not recover [9,10,11]. In this situation, the grade of WRCCMA is the lowest. Therefore, the membership function is as follows: 𝜇1𝑎(𝑏)=⎧⎩⎨ 1,0.3,0,𝑏>𝐻𝑑𝐻𝑘<𝑏≤𝐻𝑑𝑏≤𝐻𝑘,μ1a(b)...
For example, a dry air cooling system for a natural gas combined cycle generator consumes and withdraws 0.00–0.02 L/kWh, whereas a wet cooling (open recirculating) system for a coal steam turbine consumes 0.53 L/kWh and withdraws 132.5 L/kWh. Efficiency varies significantly, ...
c, In-situ catalytic cycle. Reaction conditions: 100 mg catalyst, 80 °C, 3.2 MPa (CO/C2H2/Ar = 6:5:89), 10 ml H2O. The reaction was cycled by charging new feed gas into the system without separating the catalyst and solution. TOF is calculated as specific mole rate of ...
It is also a point in the hydrological cycle when underground water enters the land surface and afterward flows into a stream (Water science school, 2018; Chukwu, 1999). A spring may be the result of karst topography where surface water has infiltrated the earth’s surface (recharge area),...
The successive time interval is 30 min for each cycle [31]. 2.6.11. Effect of saline environments In investigate the salt solution effect; hydrogel specimens were emerged into saline solutions (NaCl, CaCl2 and AlCl3) with different ionic strength according to the above mentioned method. 2.6....
