Natural gas is widely used as fuel in the process industries, so the price of natural gas is often an important variable in economic analysis. Develop a 15-year forecast of U.S. natural gas prices. Historic natural gas prices are available at www.eia.doe.gov. The "industrial" price data set is most typical of the contract prices paid by large industrial consumers. Consider any structural changes that may have occurred in the natural gas market when making your forecast.
Reconsider the Methanol Water Distillation. If the feed stream contains 60 mol % methanol, reevaluate reflux ratio, number of stages required, and the column diameter.
Determine the number of barrels of mud gained due to pumping the slug and determine the feet of dry pipe. Mud weight = 12.6 ppg.Slug weight = 14.2 ppg.
The viscosity of the liquor is 0.7 mN m-2 s. The cutoff crystal size required is 5 μm. Select a suitable type of centrifuge to use for this duty.
Main objectives of the computer aided modeling and simulation system - Critically analyze the applicability, domain, features and advantages of the various systems available.
A plant has a batch of 100 kmol of a liquid mixture containing 20 mol% benzene and 80 mol% chlorobenzene. It is desired to rectify this mixture at 1 atm to obtain bottoms containing only 0.1 mol% benzene. The relative volatility may be assumed con..
