After the oil embargo ended, the use of ethanol increased, even though the price of oil fell and for years stayed low. Ethanol became cheaper to make as its production technology advanced. Agricultural technology also improved, and the price of corn dropped. By 1992, over 1 billion gallons of fuel ethanol were used annually in the United States, and by 2004 usage had risen to over 3.4 billion gallons. Many farm groups began to see ethanol as a way to maintain the price of corn and even to revitalize the rural economy. This economic support for ethanol coincided with a further justification for its use: to promote clean. | Paper Industry Information Measurement technology for reliable paper production Looking Forward VEGA Contents Responsibility for people and products 3 Partnership for a demanding industry 4 plics - easier is better 6 Adjustment and system integration 8 Application examples Cellulose production 10 Waste paper and stock preparation 14 Stock preparation 16 Process stabilization in the approach system 17 Paper and paperboard machine 18 Dry section 20 Chemicals and auxiliary materials 21 Instrument overview 23 2 Responsibility for people and products VEGA s comprehensive offering of products and services for level switching and pressure measurement is setting the standard in the paper industry.
