Detailed steps to determine the necessary length of the  parallel flow  heat exchanger.  In this tutorial, we'll explore how to size a parallel flow concentric heat exchanger.   Here, hot oil is cooled by water that jackets it. The given information includes: Oil: Enters at 100°C and leaves at 60°C Mass flow rate: 0.15 kg/s (kilograms per second) Heat capacity: 2131 J/kg°C (joules per kilogram degrees Celsius) Convective heat transfer coefficient: 38.8 W/m²°C (watts per meter squared degrees C) Water: Enters at 25°C and leaves at 50°C Convective heat transfer coefficient: 2250 W/m²°C (watts per meter squared degrees C)   We aim to determine the length of the tube required for the necessary cooling. We'll make a couple of assumptions: negligible heat loss to the surroundings and a thin wall between the fluids, implying no conductive heat resistance between them.   Governing Equation Our heat transfer rate (𝑄) is given by the equation: Q=U×A×ΔT log mean ​ ...

  Steam Requirements for Heating Water in a Heat Exchanger When designing and operating heat exchangers, one common question is: how much steam is required to raise the temperature of water to a desired level? This blog provides a detailed step-by-step guide to perform these calculations using two different examples. Example 1: Case Study:   We have a hot water absorption heater with the following parameters:   Mass flow rate of hot water: 131.9 cubic meters per hour (36.63 liters per second). Initial temperature of water: 85°C. Desired temperature increase: From 85°C to 92°C (ΔT = 7°C). The specific enthalpy of steam at 8 bar is 2767 kJ/kg, and the specific heat capacity of water is 4.19 kJ/kg°C.   Solution:   Calculate the Heat Load (Q): 𝑄=𝑚˙×𝐶𝑝×Δ𝑇 𝑚˙=36.63 kg/s C p =4.19 kJ/kg°C Δ𝑇=7°𝐶 Q=36.63×4.19×7=1074 kJ/s   Calculate the Required Steam Flow Rate: Δℎ=2767−419=2348 kJ/kg 𝑚˙steam=𝑄/Δℎ=1074/2348=0.457 kg/s ...

Understanding Distillation Towers: Types, Operations, Reboiler and Condenser In this blog we will l earn about the different types of distillation towers, including binary and multi-draw towers, their operations, and the essential components like reboilers and condensers used in various industrial processes. Distillation towers are designed in a variety of ways to meet the demands of particular applications. A distillation tower or column can be categorized by the number of products that leave the tower.   Two common types of towers that are identified this way are binary towers and multi-draw towers.   A binary tower separates a feed into two products. For this reason you may also hear a binary tower referred to as a two-product tower. Some binary towers separate one light component from a range of heavier components, but they are still considered to be binary towers because only two products leave the tower.   Multi-draw towers separate a feed into more than two p...

  Plants like this one spend millions of dollars every year to produce marketable, usable products. And just about all of these products will at some stage go through a process called distillation.   It's a process based on the simple principle that different substances can be separated by their respective boiling points.   In practice, however, this separation process can become quite complex as many different variables enter the picture.   In this blog, we'll go through the basic principles of distillation and then focus on what you, the operator, can do to make the operation work more safely and efficiently.   But let's start with the basics. The properties of various substances are determined to a large extent by the size and structure of their molecules. In distillation, the property we're most concerned with is boiling temperature. Substances composed of large heavy molecules tend to boil at high temperatures, while smaller, lighter compounds hav...
