Previous issue date: 2016-07-29 / O prop?sito deste trabalho ? descrever os procedimentos de desenvolvimento de um material
alternativo para isolamento t?rmico a alta temperatura de tubula??es de distribui??o e inje??o
de vapor mediante o reaproveitamento do refugo de materiais isolantes comerciais tais como o
silicato de c?lcio e a l? de rocha associados em forma de blendas com o rejeito de perfura??o
de po?os de petr?leo terrestre. Este trabalho dividiu-se em tr?s principais partes, a primeira
refere-se ? coleta e prepara??o das amostras de materiais como encontrado em campo, ou seja,
materiais que j? foram submetidos ?s altas temperaturas de processo, a segunda foi o
planejamento com o aux?lio do software comercial para planejamento de
experimentos Design-Expert? V10 e execu??o dos ensaios de determina??o da condutividade
t?rmica para as composi??es planejadas com o uso do equipamento medidor de condutividade
t?rmica KD2-Pro da empresa Decagon Devices, Inc., os resultados destes ensaios foram
realimentados no Design-Expert? V10 para gera??o de um modelo matem?tico com sa?da
gr?fica das curvas de n?vel que representam as blendas tern?rias e por fim executou-se uma
simula??o num?rica em regime permanente com o uso do software comercial Ansys? para
comprovar teoricamente a aplicabilidade do novo material como isolante t?rmico para
conserva??o de energia e prote??o pessoal. Os resultados obtidos na simula??o num?rica
apontaram que foi atingida uma temperatura m?dia m?xima de 57,3?C e 59,3?C nos ensaios
experimentais na superf?cie de uma prote??o mec?nica em alum?nio do isolamento t?rmico
projetado com uma espessura 38,1 mm e aplicado a uma tubula??o de a?o carbono di?metro
nominal tr?s polegadas sch. 80 quando submetida a uma temperatura de 313?C. / The purpose of this work is to describe the procedures for the development of an alternative
material used for thermal insulation in high temperatures of steam injection pipes through the
reuse of waste commercial insulation materials such as calcium silicate and rock wool
associates of blends forms with waste of on-shore oil well drilling. This work was divided
into three main parts, the first relates to the collection and preparation of samples of materials
as found in the field, i.e., materials that have been subjected to high temperatures process, the
second was design of experiment and planning with the aid commercial software for DOE
Design-Expert? V10 and execution of the determination of thermal conductivity tests for
compositions designed using the thermal conductivity meter equipment KD2-Pro of the
company Decagon Devices, Inc., the results of these tests were fed back into the Design-
Expert? V10 to generate a mathematical model with graphical output of contour lines
representing the ternary blends and finally was executed a computational simulation on a
steady state basis with the use of commercial software Ansys? to theoretically prove the
applicability of the new material as insulation for energy conservation and personal
protection. The results of the computational simulation showed that a maximum average
temperature of 57,3?C and 59,3?C to the experimental results in the external surface of
mechanical protection of thermal insulation designed with a total thickness of 38.1 mm
applied in a carbon steel pipe with nominal diameter of 3 inches and schedule 80 when
subjected to the temperature of 313?C.
