Study On Design And Accounting Method Of Dehydration Absorption Tower For Glycolysis

Dehydration absorption tower is the core equipment of ethylene glycol dehydration process system, dewatering absorption tower directly influences the performance of the process system of processing capacity, production quality and energy consumption quota.Absorber design and calculation process trival, large amount of calculation and application of auxiliary software can greatly improve the efficiency of absorption tower, process design and calculation accuracy.Tower in domestic, the apparent in some design software still has some defects, such as low version, such as poor universality and insufficiency.Is commonly used in this paper by the method of glycol dehydration process of plate type absorption tower as the main research object, from the structure design, fluid mechanics calculation and the tower body three angles, the strength design of the main research work is as follows:(1) Tracking and retrieval method of glycol dehydration technology in domestic and foreign design, the absorption tower design and optimization technology and the latest progress in related fields, research designed and auxiliary equipment in domestic and foreign software function characteristics, scope of application and development trend.(2) Conclude the water content of natural gas formula calculation method, the applicable scope of the evaluation of different formulas. Determine the glycol solution physical parameters, the calculation method of lean glycol concentration and circulation.(3) Complete dehydration absorber tower body, the overflow area, opening area, reduced liquid device, gas liquid contact element process design methods, such as research, proposed plate plate area allocation and hole and valve solutions, determining dehydration absorption tower process design process.(4) The blister tray, float valve tray and mesh plate hydraulic parameters calculation method of accounting content including dry plate pressure drop, liquid layer resistance, downcomer liquid flood, flooding smuggled with foam fog, etc., put forward three kinds of plate method defines the elasticity of operation of four cases are given absorber hydraulics parameter tuning steps.(5) The plane assumption analysis dehydration absorber natural vibration characteristics of absorption tower is deduced from the formula of vibration period, the basic mode under the influence of absorption tower by earthquake load, seismic moment, wind load and bending moment calculation method of wind, determine the tower body bearing strength and stability checking index.Real beam method and the virtual beam method was used to study the six top deflection calculation formula under the influence of the reaction, determine the different to the top of the tower diameter range deflection control values.(6) Based on C#programming language and Microsoft Visual Studio2010platform development method of glycol dehydration absorption tower Design and calculation of auxiliary software the TDT-Design, implementation of dehydration absorber design, hydraulic calculation, strength Design and stability checking, etc. The TDT-Design has a good input and output functions, operation, interface aesthetics, calculation result is reliable, strong universality.(7) Using the above research results and TDT-Design software design and accounting field A TEG dehydration dehydration process system of absorption tower. The tower operation stable performance and can meet the demand of field A production process.
