“…Of all the oxygenates, tertiary ethers are preferred by refiners to lighter alcohols, among other reasons, because of their lower bRvp and lower vaporization latent heats and their full fungibility in the petroleum refining and distribution systems. Currently, the most common ether is methyl tert-butyl ether (MTBE) because low methanol prices make MTBE a more atractive option than ethyl ieri-butyl ether (ETBE) (Anderson, 1988). Nevertheless, some of the US states and a few of the European Community countries are planning to use ETBE produced from bioethanol as an alternative to MTBE (Oxy-Fuels News, 1992a,b).…”

“…On the other hand MTBE plants can easily be revamped into ETBE. So, it seems that MTBE producers are mainly interested in the flexibility of MTBE/ETBE plants (Anderson, 1988;Forestiere et al, 1991). Another factor that could reduce ethanol cost is the possibility of using azeotropic ethanol (96.5 wt %) (Bakas et al, 1990;Cunill et al, 1993) or subazeotropic ethanol (80-85 wt % ) 0888-5885/94/2633-0581$04.50/0 (Jayadeokar and Sharma, 1992) as a raw material for ETBE production.…”

“…Methyl tertiary butyl ether (MTBE), ethyl tertiary butyl ether (ETBE), and tertiary butyl alcohol (TBA)-three major gasoline octane enhancing chemicals-are likely candidates for use as gasoline oxygenates. Among these three, MTBE is the most favored (Anderson, 1988;Alnsworth, 1991). It is estimated that the production of MTBE will increase 25% per year over the next four years to meet the expected demand (Alnsworth, 1991).…”

This study evaluated the biodegradation of methyl tertiary butyl ether (MTBE), ethyl tertiary butyl ether (ETBE), and tertiary butyl alcohol (TBA)-three chemicals used as gasoline additives. The biodegradation under sulfate reducing, methanogenic and denitrifying conditions was measured in static soil and water microcosms using soils of different origin and varying characteristics. The results indicate that TBA was the easiest compound to biodegrade, whereas MTBE was the most recalcitrant. It is thought that cleavage of the ether bond in MTBE and ETBE is the first and rate-limiting step in the degradation of these organics. TBA degradation was enhanced by nutrient addition in the nutrient poor soils but hindered by the presence of other easily-degraded organic compounds. Degradation of MTBE and ETBE occurred only in the soil with the lowest organic matter content and with a pH around 5.5. No degradation of MTBE and ETBE was observed in the organic-rich soils, and in the organically poor soil the addition of easily degradable organic compounds inhibited MTBE and ETBE degradation.

Thermal integration of homogeneous azeotropic distillation sequences

1990

View full text Add to dashboard Cite

Existing methods for synthesizing thermally-integrated distillation sequences fail frequently when applied to nonideal and azeotropic systems, because increasing the column pressures often introduces new azeotropes and distillation boundaries into the mixture, which make some separation tasks infeasible. A new thermal integration procedure is presented that combines a bifurcation and residue-curve map analysis with the methods of Andrecovich and Westerberg. The procedure is demonstrated with two commercially important separations: ethanol-water-ethylene glycol and methanol-acetone-water. Energy savings of 65% and 40%, respectively, over the optimized nonintegrated sequences are possible.
