Envelope 2007is a chemical engineer's tool for estimating feasability of future equipment or estimating the efficiency of existing equipment. Change the way you perform "back-of-the-envelope" calculations. With this envelope, you can perform flow checks, pump specification, relief valve sizing, verify sensible heat transfer, calculate stage equilibriums, estimate physical properties, and more. Most calculations do not require elaborate process simulators to get a rough answer and can be completed in the palm of your hand. Download product and use 15 day trial period to verify results and learn about all features. Create chemical components and save their physical properties as individual files to use for heat transfer or equilibrium calculations. Also, create heat exchanger or stage files and store them on your handheld. So many features for less than the cost of most professional technical books.
