An inventor has developed a complicated process for making heat continuously available at an elevated temperature. Saturated steam at 373.15 K (100°C) is the only source of energy. Assuming that there is plenty of cooling water available at 273.15 K (O°C), what is the maximum temperature level at which heat in the amount of 2000 kJ can be made available for each kilogram of steam flowing through the process?
An effluent disposal contractor is considering entering the recycled field. At present he incinerates an organic waste containing recoverable solvents and dumps the aqueous based effluent containing acids and metals.

In the manufacture of methyl ethyl ketone from butanol, the product is separated from unreacted butanol by distillation. The feed to the column consists of a mixture of 0.90 mol fraction MEK, 0.10 mol fraction 2-butanol, with a trace of trichloroe..
For a Thermo-Finnigan LTQ-FT running Xcalibur 2.0.1 how can you automate 10 MS3 experiments where only the activation time is changed?
Calculate the relative change in the rate coefficient for the reaction at the Earth's surface (T = 295 K) and at the top of the troposphere (T = 220 K). The reaction has an activation energy of 19.5 kJ/mol.
Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 g/cm3. How much sodium carbonate was required for complete neutralization of the spill, and how ..
A civil engineer is designing a road. At what angle should he bank the road surface in a curve of radius 70m so that there is no tendency for a vehicle traveling at 90 km/h to slip sideways, either up or down the banking.
Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
