| Resumo: | 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 57,3ºC and 59,3ºC 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 313ºC. |
