Included Training Topics

• Plant On-The-Job Training and Demonstration
• Training for the way to properly do - Daily/Weekly Rounds.
• Develop a SAMPLE DAILY ROUNDS SHEET
• Compressor discharge, suction, oil temp, oil levels, dry side levels, thermosiphon, filter differential pressure.
• Vessel Levels (not just the HMI or PLC Control Panel), Recirculator Pumps types, Oil Pots (iced up or not iced up).
• Air Cooled Evaporators, ice buildup, vibration, fan operation, drip pans for leaks or plugged.
• Condensers, fans, belts, vibration, sump water level and PH levels and pump operation. HMI readout for PH Levels, foam on in water sump, leaks on condenser, water leaks, mist eliminators.
• Roof - Valve Stations on the roof, Penthouses, Silos, vibration, leaks, pipe supports, ice where there Is normally or not normally ice. (Ice Abnormality).
• Mezzanine - Crawl space how often are you looking at them?
• Sites Specific Equipment such as Oil Stills, Surge Drums, Transfer Drums, Purger, TXV valves - bulb location, etc.
• Basic Refrigeration System Video -Industrial Refrigeration system Basics - Ammonia refrigeration working principle.
• Refrigeration Cycle Diagram
• High side/ Low Side (High Discharge and Suction), High Side – HPR, Condensers, Compressors, Low Side – Evaporators, Compressor, Recirculators, Accumulators, etc.
• Review of the plants Piping and Instrumentation Diagrams and Block Flow Diagram (Facility Specific)
• Site specific SOPS – 1 for Each Type Compressor, Condenser and Evaporators, Recirculators, Surge Drums
• Normal Operating Ranges for Compressors, Condensers, etc. and WHY
• Vessel Operating Levels
• Consequences of Deviations and Corrective Actions from Normal Operating Ranges (REPORT ONLY), (What can cause High Head Pressure? What can cause a Compressor to Shut down?
• Review the SOP for Charging the System with Ammonia – Sites Procedure (based on regular Maintenance activities, or during a MOC).
• Video – charging the system with ammonia.
• Emergency Action Plan and Response
• Emergency Shutdown of System if needed. (based on Corporate Policy).
• Hit the E-Stop in the Compressor room
• HPR or TSR leak
• SOPS – Emergency Shutdown of the system
• Release at an EVAP (Emergency Shutdown, High Pressure Receiver, how do you isolate it, can you isolate a valve upstream, or only at the unit, when to hit the E-Stop Button?
• Minor Ammonia Leak (Facility SOP Review) (Video of Engine Room Leak and Explosion)
• Ammonia Handheld Detector Meter Use (how to use them and make sure they are calibrated. (Demonstration)
• Respirators and Papr hoods (Sites Specific Respirators)
• Awareness of the Maintenance Logs and purpose in Machine Room, Nuisance Odor Logs, Oil Draining Logs, Purge Logs, Ammonia log for inventory.
• Oil Draining Procedure/Locations of Oil Draining (Facility SOP Review)
• The difference between Operating Procedures and Maintenance Procedures and the requirements for both.
• Samples of Maintenance Procedures (IIAR-6 Requirements)
• Discuss Ammonia Safety Systems and Devices and Their Functions
• SRVs replacement procedure, Testing the Compressor Cutouts, High Level Floats on Vessels, Testing E-Stops, Ventilation Switches.
• The Functions of each – Plant specific - What should happen if the Emergency Ventilation goes off? If the Ammonia detector activates, does it turn on Emergency Ventilation etc. E-Stop shuts down all the compressors and turns on ventilation.
• Detectors/Sensors
• Ammonia Detectors (locations) (PPM) Alarms Levels and Testing Requirements
• Handheld Detectors (locations) (PPM)

Classroom Type

This is an 8-Hour LIVE-ONLINE WEBINAR, totaling 1 day of comprehensive training.

Classroom is Minimum (10) participants. NH3 may cancel this session if the participation goal isn’t met.

The key to the success of this training program is to ensure you will have the necessary knowledge and skill set to perform your job with integrity and quality. Therefore, you will be given Tests throughout the training, to ensure you have learned the materials.

NH3 Training Center of Texas, LLC shall ascertain that each Student has received and understood the training. NH3 Training Center of Texas, LLC will prepare a record which contains the identity of the student, the date of training, and the means used to verify that the student understood the training.
