Saturated steam at 260 °f is to be used to concentrate 10,000 Lb/hr sodium hydroxide solution available at 100 "F from 10 to 40% in a single effect evaporator. A pressure of 1.9 psi is to be maintained in the vapor space. The overall heat- transfer coefficient can be assumed to be 200 Btu/Ft hr 'F. Calculate the steam consumption in Lb/hr, the economy, and the heating surface required in Ft.

### Problem Statement for Educational Exercise #### Concentration of Sodium Hydroxide Solution using Saturated Steam 3. **Process Description:** Saturated steam at 260°F is to be utilized to concentrate a sodium hydroxide solution at a rate of 10,000 Lb/hr. The initial concentration of the solution is 10%, and it needs to be increased to 40% in a single effect evaporator. **Operating Conditions:** - The solution is initially available at 100°F. - A pressure of 1.9 psi is to be maintained in the vapor space. - The overall heat-transfer coefficient is assumed to be 200 Btu/Ft² hr °F. **Objective:** Calculate the following parameters: - **Steam consumption (in Lb/hr)** - **Economy of the process** - **Required heating surface area (in Ft²)** Students are required to apply principles of thermodynamics and heat transfer to solve for the steam consumption, economy, and heating surface area in this evaporative concentration process. Consider using relevant formulas and data for the physical properties of water and steam in your calculations. This practical exercise will help in understanding the principles involved in the design and operation of evaporators, critical for applications in chemical engineering and process industries.
