Abstract

A method of erecting a cold box that includes the steps of anchoring at least one column to a foundation in a substantially vertical orientation; anchoring a pipe rack module to the foundation in a substantially vertical orientation, wherein the pipe rack module is in close proximity to the at least one column; attaching interconnecting piping between the pipe rack module and the at least one column; anchoring at least four corner beams to the edge of the foundation in a substantially vertical orientation; attaching prefabricated panels with bracing to the corner beams, to form an enclosure around the column and piping; and attaching a roof to the enclose is provided.

Claims

1. A hybrid method of erecting a cold box in the field utilizing prefabricated and field erected components, said method comprising the following steps:

a. anchoring at least one prefabricated distillation column to a foundation in a substantially vertical orientation;

b. anchoring a pipe rack module to said foundation in a substantially vertical orientation, wherein said pipe rack module is in close proximity to said at least one distillation column;

c. attaching interconnecting piping between said pipe rack module and said at least one distillation column;

d. anchoring at least four corner beams to an edge of said foundation in a substantially vertical orientation;

e. attaching prefabricated panels with bracing to said corner beams, to form an enclosure around said distillation column and piping; and

f. attaching a roof to said enclosure.

2. The method of claim 1, wherein said pipe rack module is prefabricated.

3. The method of claim 1, wherein said prefabricated panels are attached to said corner beams by bolting.

4. The method of claim 1, wherein said prefabricated panels are connected vertically or horizontally.

5. The method of claim 4, wherein said prefabricated panels are attached to the edge of said foundation or to adjacent prefabricated panels with bolts.
