“…[14] During the exploration of oil fields, oily brine is often wasted as a by-product, which also has potential value to resolve the clean water shortage issue especially in arid areas such as deserts. [15,16] Nature, however, offers a remarkably excellent solar steam generation device. [17][18][19] Research on the development of new bio-sourced materials has thus been attracting more and more attention.…”

Solar-driven water evaporation is considered to be an appealing way to solve water scarcity issues globally. Various natural creatures possess unique structural features and exhibit an excellent pumping ability in arid environments. Motivated by sunflower stalk pith, here, the biomass porous foam modified with zwitterionic hydrogel coating for solar desalination devices is introduced. It is demonstrated that the multi-curvature and gradient honeycomb architecture offers a remarkable solar desalination system, which combines critical aspects of solar evaporation including high light absorption, localizing converted heat, rapid water transport, water activation, and multi-channel release of steam via its ubiquitous structure, and substantially outperforms other natural biomass materials. The device exhibits long-term stability in actual seawater, as well as high performance for soybean oil emulsion and oily brines (crude oil, salts). Furthermore, the long-term use of excellent storability to prevent putrefying is shown, which is attributed to the outstanding antifouling property of zwitterionic hydrogel. It is envisioned that the nature material with the advantage of being inexpensive, environmentally friendly, and portable, may be a new candidate for water purification and desalination.

“…The method for measurement of TOG by infrared spectrometry typically uses a Horiba OCMA-350 analyzer, which is designed to measure contamination by hydrocarbons in samples of fresh and salt water as well as soil [8]. This instrument operates on the technique of energy absorption in the infrared spectrum, with a wavelength range from 3.4 to 3.5 micrometers.…”

Abstract. Infrared spectrometry and spectrofluorimetry methods were correlated in the measurement of oil concentration in produced water. Furthermore, we compared colorimetry and gravimetry techniques. Adsorption experiments were performed in synthetic oily wastewaters by polymer compounds based on poly(hydroxyethyl acrylamide and polypropylene. The residual oil content was used in the techniques correlation.

“…Chemical additives act by modifying the structure of the wax crystals and impeding their growth and agglomeration. Polymers are extensively used in petroleum production,1, 3, 10–14 and the typical wax deposition inhibitors are polyacrylates, polymethacrylates, and ethylene‐vinyl acetate copolymers (EVA), among others 7–9, 15, 16. No inhibitor is universally effective, and so there is a need for laboratory tests to select the best ones, considering their compatibility with the materials of the injection system and stability under the pressure and temperature conditions in the field 17…”

Chemical inhibition is one of the traditional methods used by the petroleum industry to prevent or correct the problems caused by the formation of organic deposits. In this work, three samples of poly(ethylene-co-vinyl acetate)s (EVAs) were added at different concentrations to three different Brazilian crude oils, and their effect on the wax appearance temperature (WAT) and crystallization enthalpy of the oils was evaluated as a function of increasing pressure and the type of saturation gas, using high-pressure microcalorimetry (HPlDSC). The results show that different copolymer compositions present dissimilar performance in reducing WAT, and, in some cases, an optimum concentration was observed. When rising pressure, a positive influ-ence on the WAT is observed, but the performance of organic deposition inhibitors that are ineffective at atmospheric pressure is not enhanced at higher pressures. On the other hand, additives able to modify the crystallization kinetics of waxes at atmospheric pressure show a synergy when evaluated in the presence of light fractions and under high pressures. HPlDSC analysis is an important tool to optimize the additive concentration to be used in oil fields.
