Systems and methods for compression pack pipe insulation

Abstract

An insulation product for a pipe or vessel having at least one aerogel insulation layer, an additional insulation layer positioned around the at least one aerogel insulation layer, and a protective cladding layer surrounding the at least one aerogel insulation layer and the additional insulation layer.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a division of pending U.S. application Ser. No. 15 / 586,082 filed May 3, 2017, the entire disclosure of which is hereby incorporated by reference herein for all purposes.BACKGROUND OF THE INVENTION[0002]Industrial tanks and vessels used for cryogenic applications are typically insulated by exterior applied insulations, such as cellular glass or PIR foam combined with one or more vapor barrier layers. In applications where higher performance and lower boil off are desired, storage tanks are often constructed as double wall vessels. Typically, in such applications the annulus space is filled with MLI, expanded perlite, or JM Cryolite® insulation, sealed, and then evacuated. Up to 20% of the cryogenic piping at LNG facilities that export products have requirements to meet certain noise standards. The compressors used in the liquefaction process generate loud noise that is radiated along all the pipes connected to the compr...

AI Technical Summary

Benefits of technology

[0004]Embodiments of the invention relate to an insulation and insulation systems for pipes, storage tanks, and vessels. The insulation and insulation systems described herein provide excellent thermal and acoustic performance with minimal thickness compared to conventional insulation solutions. The present insulations are particularly useful for applications involving cryogenic liquid storage tanks and other storage containers that store liquids below 300° F. where insulation thickness needs to be minimized. The insulations may also be used in applications that utilize traditional cryogenic insulation, such as cellular glass or PIR foam, but that also require acoustic performance without adding significant thickness. Additionally, the insulation and insulation systems of the present invention are faster and easier to install than conventional insulation products.

Problems solved by technology

The compressors used in the liquefaction process generate loud noise that is radiated along all the pipes connected to the compressor.

Typically, such cryogenic applications require custom made shapes and sizes of insulation that significantly increases the cost and time associated with insulating a pipe or vessel.
