Alumina-supported Ni-promoted W oxides, carbides and nitrides were presulfided and employed for reducing pollutants and increasing the quality of an extra-heavy crude oil during catalytic upgrading reactions. These materials were prepared by…
A large amount of sludge produced in the processing of crude oil has brought great harm. In this paper, common flocculants are summarized. According to the treatment process of crude oil, flocculants are divided into organic flocculants, inorganic…
Produced water (PW) of the liquid phase is the largest volume by-product from the process of offshore oil and gas production, and compact and efficient treatment methods are brought into focus. The PW, condensate oil, and floccule in the liquid phase…
The performance of coalescing filter cartridges (of four different specifications) after a 410-day field operation for the high-pressure natural gas purification has been evaluated in this study. Our evaluation of field-tested filter cartridges…
In the petroleum industry, oil and water emulsions are frequent, not only in oilfield operations but also during the transportation and refining processes. Once depicting emulsion formation and stabilization, it is essential to analyse how it is…
Fluid fine tailings (FFT) are a by-product of the oil sands bitumen extraction process and are composed of sand, fines (silts and clays), water, and residual bitumen. FFT can take decades to settle without intervention due to the small size of…
