Application:
Vessel and Exchanger Skid for Refrigeration. Addition of “Economized 2nd and 3rd Stage Suction” for increased Chilling Duty
Objective:
Equipment addition was added to an existing order. The addition of the Economized Flow to 2nd and 3rd stage increased the chilling duty by 50% without the addition of any increased HP consumption.
Design Challenges:
Integration of new equipment into site with existing refrigeration equipment & use of free issued equipment and Compass procured equipment.
Compass Solution:
Close consultation with client and engineering contractor. Cost plus contract administered by Compass, final cost of the associated equipment was approx. 10% below projected costs of original estimate. This was achieved through tight project management, design and shop execution.
Major Equipment Specifications
Exchangers:
5 x shell and coil exchangers for cooling process propane and butane and fuel gas. Economized “Thermal Siphons” were used.
Control Panel:
Allan Bradley PLC based Micro Logix controller
