EGMBE

Adsorption of corrosion inhibitors or cationic surfactants can reduce sandstone formation permeability. Alcohols can be used to remove corrosion inhibitors from rock surfaces. Oil-soluble corrosion inhibitors may be dissolved by organic solvents such as xylene or toluene containing a mutual solvent, most often ethylene glycol monobutyl ether, EGMBE (167). Aqueous fluids containing 5-10% EGMBE can be used to dissolve cationic surfactants.

Figure 11 shows the variation of surface tension of 15 wt% HCl with mutual solvent (ethylene glycol monobutylether, EGMBE) concentration. The surface tension decreases with mutual solvent concentration up to 10 wt%, then remains constant. Mutual solvent acts as a surface-active species. A similar behavior was noted by D Angelo and Santucci [63] when mutual solvent was added to distilled water. 

The first attempts to use interactive stationary phases for the separation of polyolefins started in 2003. Macko et al. used an isocratic separation system for PE-PP blends [136,137]. For the separation of the two polymers, TCB was used as a thermodynamically good solvent for both components and ethylene glycol monobutylether (EGMBE) as eluent. Dimethylsiloxane-modified silica gel was used as stationary phase. As a result, PE eluted almost irrespective of its molar mass under limiting conditions, while PP eluted in the SEC mode before the PE components. Resolution of this method, however, was rather poor and additionally limited by the poor solubility of the polyolefins. These results triggered some in-depth studies on the solubility of polyolefins in different solvents using cloud point titration [138] and the testing of zeolites as selective stationary phases [139-142]. 

Various combinations of solvents and non-solvents were tested for preparative separations of polyolefins according to their molar masses and/or chemical compositions. Lehtinen et al. [151] used ethyleneglycol monobutyl ether (EGMBE) for the preparative separation of polyolefins using the fact that EGMBE is a good...

In the treatment of sour wells (wells produdng H S gas), the possibility of iron sulfide (FeS) precipitation exists. FeS precipitates at a pH of about 2, which poses a potential problem as acid spends and pH rises. Hall and Dill have shown that a mixture of nitrilotriacetic add (NTA), mutual solvent (EGMBE), and a sulfide modifier can control the precipitation of EeS. Sulfide modifier additives are available from service companies and may be included in the iron control additive package. 

A mutual solvent, such as EGMBE, can be beneficial. Because mutual solvent is miscible in oil and water, it helps maintain a water-wet formation. Mutual solvent is effective in both oil and gas wells, but more so in oil wells. 

EGMBE can be added to add however, it may be most effective as an additive to the overflush (ammonium chloride solution). Mutual solvent will strip adsorbed additives, such as the corrosion inhibitor, from formation...
