At one food processing plant, a
complete pump-out system was installed as part of the initial installation of
the ammonia refrigeration system. It consists of a bank of pump-out valves, an
oil regenerator, and a 50 hp pump-out compressor.
In Part 1, I discussed the advantages of a pump-out system, which include enabling safer operation of the ammonia refrigeration system and providing zero emissions during plant tie-ins. In this column, I’ll look at some typical features of a pump-out system
Pump-out systems, which used to be a relatively common component of many ammonia refrigeration systems, enable ammonia to be removed quickly and safely prior to maintenance work or system modifications.
One of the critical steps in the standard procedures for starting up a refrigerating system is to evacuate the system prior to introducing refrigerant to it, regardless of the refrigerant being used.
Refrigeration systems expert George Briley
talks about why refrigeration system owners
and operators should be aware of the
potential safety problem of faulty insulation.
Ammonia refrigeration expert George Briley
continues his series about defrosting ammonia
refrigeration systems. In this installment,
he answers the question, "So, what’s the best way to design a hot-gas defrost system?"
George Briley explains how to keep regulators at 'ARMs' length with a process safety management document for those covered by OSHA?s General Duty Clause.
George Briley talks about a special industry
task force that will take on the job of devel-oping
ammonia refrigeration training guide-lines
for operators.
As a good businessperson, you want to make sure your ammonia refrigeration system operates easily, runs efficiently and requires minimal maintenance. Here are 10 ideas that will help you achieve these goals.
