Changes i gasoline

[Q45tech]

"The State of California banned the use of MTBE in gasoline starting in December 2002 with a 2 year phaseout period: 0.3 v% max in 2003, 0.15 v% in 2004, and 0.05 v% afterwards. This caused a political chain reaction and other states have passed or are in the process of passing similar legislation.

What are the implications? We lose about 11% of volume, representing the percentage of MTBE in gasoline. We also lose the contaminant dilution effect (10-15% for S, 6 to 8% for aromatics, and 0.2 to 0.3% for benzene). MTBE is also a high octane component (118RON), and its elimination reduces the blend octane by 2 to 3 octane numbers. Finally it raises the T50% by 20 degrees.

The situation can be helped through the use of more expensive alternatives:

1. Use of Ethanol (~ 6 v%) provides the oxygenate content mandated by EPA RFG-2, regains 6% of volume and associated dilution benefits, and gains some octane

2. Use of Alkylate regains some of the volume and associated dilution benefits, helps compensate for Ethanol RVP problems, and gains some octane

3. Gain octane by using higher octane reformate and FCC gasoline by increasing process units severity "

http://www.cheresources.com/greengas.sh ... 8.pdfAfter studying the above assume that your Xmas bonus is tied to profitability and your wife will cut you off if she doesn't get a big present..............plus you know that few states test octane and you can always blame it on the pipeline or storage facilities if your company gets caught..........how much will you cheat............will you sell 89.99999 octane as 93 octane?

Are you a smart enough chemist to make the blend pass at the refinery [so you have a printed record] and rapidly degrade saving a penny a gallon or $10,000 per day which nets YOU a $5,000 BONUS.

"However, for premium unleaded, 18 out of 1164 samples (1.5%) are not meeting the posted octane level and have been sent on to the Attorney General. At this point, it appears if there is going to be a problem with octane in Oregon, it is more likely to be with the higher octane gasoline."http://www.oda.state.or.us/inf....html

""Hobbs was cited for violating N.C. General Statute 119-7 referring to deceiving the public about the quality of a fuel," said N. David Smith, director of the Standards Division. "We found 22 instances where Hobbs delivered regular gasoline into regular and premium tanks at 16 different retail stores."

Inspections of the bills of lading for the deliveries in question revealed that Hobbs' tanker trucks only carried regular gasoline, but pumped this gas into regular and premium tanks at the stations in every instance.?
