One of the stages of the manufacturing process of aluminum components is the heat treatment, this The process could represent up to 20% of the total consumption of natural gas at the Mx site. This process It consists of three stages which involve a heating of aluminum components and their basket of temperatures from 480 C to 530 C for the solution stage and 180 to 240 C in the stages of aged The ovens are the type of rollers and their fuel is natural gas with a cost of $ 3.2 USD / MMBtus

Operational patterns can be considered from 20 hrs per day for 300 business days, the total efficiency of various enters each oven (see table). It is predicted that a decrease of 20% demand, where the current demand for the TT process is 4.5 M of equivalent parts. goals Through the knowledge obtained in the course, experience and using practices defined by the DOE (U.S. Department of Energy): - Define an energy operation strategy based on operational data. -Define three project options to reduce energy consumption which have an ROI of At least 1 year. -For each proposed strategy or scenario, determine a matrix of benefits vs. risks. -Perform an exergy analysis for flue gases of a temperature of 400 C Scope Energy improvements focused on saving natural gas Energy cost of natural gas $ 3.2 Usd / MMBTUs Calculate consumption for both the solution and aging processes
