My name is Raunak. I am writing from India. I am presently working on a centrifugal compressor (wet gas-hydrocarbon) layout for a refinery in Calgary, Canada. I am struck up on ventilation requirements for compressor shelters and need help from members. I need guidance on the following aspects:
As per API RP 500/505 if out of the 4 walls of the shelter 50% or less is closed
(covered) then the shelter is said to be adequately ventilated. Hence the
compressor motor with Zone-2 rating can be used. If more than 50% is covered,
then Zone-1 is preferred, which is more stringent.
Our Client is asking for the balance of a shelter which gives adequate
protection from snow storms and winter winds and at the same time give adequate
ventilation as the motor is already procured in Zone-2.
We are proposing to provide fixed louvers for some part and sheet cladding for
the remaining in our design.
I wish to know as to how to determine the extent of louvers that must be
provided which will meet the 50% or less guideline. How should the louvers be
spaced? Is there any readily available dimension guide lines for these louvers,
so that they can be represented in the information drawings.
Regards,
