Multiple effect evaporator solved problems pdf

In the operation of the multiple-effect evaporators there is a number of aspects which incide in their performance. These aspects which are variables or parameters rulling the evaporation process Multiple effect evaporator performance analysis for-design and operation. Multiple Effect Evaporators - Introduction. 221 311 просмотров 221 тыс. просмотров. Overview of a multiple effect evaporators. Свернуть Ещё. The evaporators / concentrators are the largest energy users in a Kraft pulp mill and represent one of the areas of the mill where significant savings in production costs The principle of operation of the multiple effect evaporator is that live steam is used in the first effect to evaporate water. There could be single effect evaporator or multiple effect evaporators. With addition of each effect steam economy of the system also increases. The system consists of quadruple effect having falling film evaporator as each effect. There is forward feed flow. Designing of this system has been done. Multiple-effect evaporation proved useful in both achieving purer vapor and lowering the total required heating power. Flash models with different temperature increments were constructed. The aim was to solve an temperature increment that would be satisfactory to 8.2. Multiple-effect evaporator. Chapter 5 Multiple Effect Evaporators1 Multiple Effect Evaporator In case of a single effect Multiple Effect Evaporator Putting new values, energy balance for second effect equation (5) Practice Problem 1060 kg/h of 4% (by weight) caustic soda solution is fed to a quadruple-effect A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Single Effect Evaporator ChE 3787L Unit Operations Lab I Dr. Sundar Vaidyaraman 9/25/2003 Group 3 Team Leader: Ashley King Team Members: Ricardo Cruz, Tony Koulianos, Courtney Running the evaporator under a vacuum proved to be more efficient with respect to steam usage for evaporation. 4. Multiple Effect Evaporator Problem Guided By Prof. M.G.Desai Page | 4 ABSTRACT During our visit to the ATUL LTD.,ANKLESHWAR we found in Multiple Effect Evaporator plant that steam utility increases with the time for the production of sodium sulfate. Multiple-effect evaporators configuration. Process diagram where a multiple effect evaporator is located. EVAPORATION. FS-AVA-003. As the water evaporates from a solution and the liquid becomes more concentrated, it is possible to reach the precipitation point of solved salts. • In a multiple effect evaporator, water is boiled in a sequence of vessels, each of which is at a lower pressure than the last. Schematic of multiple effect evaporator. MEE is very simple in operation and the most proven system for evaporation. It is the least energy efficient of all evaporation types, however. study112.3 Methods of modeling of multiple effect evaporator systems12Chapter 31314PROBLEM STATEMENT15Chapter ABSTRACTA septuple effect flat falling film evaporator system for the concentration of blackliquor is studied and a generalized cascade algorithm is developed for the study112.3 Methods of modeling of multiple effect evaporator systems12Chapter 31314PROBLEM STATEMENT15Chapter ABSTRACTA septuple effect flat falling film evaporator system for the concentration of blackliquor is studied and a generalized cascade algorithm is developed for the Download & View Single Effect Evaporator Problem as PDF for free. THE SINGLE EFFECT EVAPORATOR The typical evaporator is made up of three functional sections: the heat exchanger, the evaporating section, where the liquid boils and evaporates, and the separator in which the vapour Double effect evaporator solved problems Lesson 5BASIC CONCEPTS OF MULTIPLE EFFECT EVAPORATORS 5.
