PHASE BEHAVIOR TESTS FOR THE ALKALINE-SURFACTANT PROCESS... 

Phase behavior tests performed in glass sample tubes (pipettes) for the alkaline-surfactant process include aqueous tests, a salinity scan (alkalinity scan), and an oil scan. The aqueous tests and salinity scan are the same as those for surfactant flooding. For the sahnity scan in AS or alkaline-surfactant-polymer (ASP) cases, alkali also works as salt. There are two ways to change salinity. One is to change the salt content while fixing the alkali content the other is to change the alkali content while fixing the salt content. Therefore, the salinity...

Figure 14.37, shows a block scheme of the viscose/rayon process from the spinning stage to production of the final viscose/rayon material. In this process, two types of surfactant process additives are introduced, i.e. spin bath additives and lubricant finishing additives.

Figure 5 illustrates the conventional diagram normally used for oil-water-alcohol (or surfactant) processes. For CO2 or hydrocarbon-miscible processes, authors conventionally rotate the ternary diagram 120° clockwise, but the illustrated principle is the same. The binodal curve is normally higher for alcohol and lower for surfactants than the curve shown in Figure 5. Although no real reservoir process can be completely miscible in the exact...

Figure 7. Sucrose-based surfactant process simplified flow diagram...

Coincidental with the development of the new low cost sucrose surfactant process, the upsurge in world mineral oil prices has led to escalations in the prices of petrochemicals and, consequently, the prices of petroleum-based surfactants. As an indication of the increase, surfactant feedstock prices in Europe have risen by 500% in the last four years.
