Thermal design of shell & tube heat exchanger. Process data attached. Please note the following design basis: 1. BEM type exchanger to be used. 2. Thermal design margin (greater of the two to be used): 20% on the clean heat transfer area or 10% on the dirty heat transfer area. 3. Number of units: 2 x 100% 4. Design pressure / temperature of tube side: FV / 98 barg // -20 / 100°C 5. Design pressure / temperature of shell side: FV / 98 barg // -20 / 110°C 6. Turndown case shall define maximum area Output expected: 1) HTRI file 2) Exchanger Datasheet

Looking for a talented chemical engineer with flavor for transport phenomena: You will be working with university assignment (master grad), something like the attached file. I require that you have good English, mathematical, thermodynamic skills and an excellent transport phenomena understanding. It is a master grade assignment, so you should either have a practical or theoretical knowledge of the subject. You will have two weeks to do the job. If you have any question, feel free to contact me. ​

As part of a wider product we require the design of a fluid delivery system that will deliver one drop (approximately 0.5 ml) of liquid approximately every 12 hours. It should only use natural forces such as gravity, diurnal temperature change or atmospheric pressure to operate. It should be purely mechanical in nature, simple and operate unattended for several years at a time. The fluid will be a mixture of a solvent similar to Turpentine with (smooth) peanut butter oils and solids dissolved and mixed in it. The resulting liquid will be filtered to remove any oversize particles. It has a viscosity similar to water but a higher density. The fluid will be stored in a flexible foil bag and will flow to the delivery mechanism by gravity. Once delivered, the solvent will be allowed to evaporate off leaving the peanut butter substrate. The temperature range of the surrounding environment will vary from 25 degrees C to - 20 degrees C. Temporary changes to the delivery rate are permissible during extremes of temperature. Please see the attached sketch. The challenge involves delivering the approximate amount of solution without the solvent evaporating and leaving a sticky blockage in any part. If you have a concept that will solve the challenge please apply.
