The thermal design of a heat exchanger to recover heat from a kerosene stream by transfer to a crude oil stream was carried out in. Make a preliminary mechanical design for this exchanger. Base your design on the specification obtained from the CAD design procedure used in the example. All material of construction is to be carbon steel (semi-killed or silicon killed). Your design should cover:
a. Choice of design pressure and temperature
b. Choice of the required corrosion allowances
c. Choice of the type of end covers
d. Determination of the minimum wall thickness for the shell, headers, and ends
e. A check on the pressure rating of the tubes
Extract ore descriptors or features from the variables and design a model that can classify the ores correctly from images of the ore
question 1nbspheat capacities cv and cp are defined as temperature derivatives respectively of u and h. show that the
Two separate metal blocks of thickness d and 2d are kept at constant temperature T0 at the top anda constant heat flux q0 is provided at the bottom. Draw the steady state temperature profile for eachof the blocks.
Name the microstructural products of eutectoid iron-carbon alloy (0.76 wt% C) specimens that are first completely transformed to austenite, then cooled to room temperature at the following rates:
Make a rough estimate of the cost of steam per ton, produced from a packaged boiler. 10,000 kg per hour of steam are required at 15 bar. Natural gas will be used as the fuel, calorific value 39 MJ/m3 (roughly 1 MMBtu/1000 scf). Take the boiler eff..
Continuous Stirred Tank Reactor (CSTR) : Flow rate and Reactor Volume, The liquid phase reactions
A flat slab of Douglas fir wood 50.8 mm thick containing 30 wt% moisture is being dried from both sides (neglecting edges and ends). The equilibrium moisture content at the surface of the wood due to the drying air blown over it is held at 5 wt% mois..
Write down a balanced chemical equation for the polymerization and Name the polymer formed by this polymerization.
Sulfur dioxide produced by the combustion of sulfur in air is absorbed in water. Pure SO2 is then recovered from the solution by steam stripping. Make a preliminary design for the absorption column.
Lowest standard deviation of measurements, As the Quality Control Manager of a chemical company, you are asked to decide between several process methods that are supposed to uniformly mix 37.4 milligrams into a chemical solution.
A completely enclosed stirred-tank heating process is used to beat an incoming stream whose flow rate varies. The heating rate from this coil and the volume are both constant.(a) Develop a mathematical model (differential and algebraic equations) tha..
Design a Heat Exchanger for the Following Duty: Reduced crude oil leaving a distillation unit with a flow rate of 3166.04 kL/d at 268 oC and is to be cooled to 243 oC by exchange with 62.8 kg/s pre-flashed crude oil coming from pre-flash unit at 206 ..
