Electrical Control System

 

The system will include an electrical panel mounted on the storage tank to house the control system to regulate and monitor the process equipment operations. The system is controlled with electrical components mounted in a NEMA 12X enclosure complete with mounted disconnect device for lock-out/tag-out. Each operational device such as pumps, heaters, auto-cycles, etc., will be controlled thru a push button station or selector switch mounted in the electrical panel door connected to an Allen Bradley Processor mounted in the electrical panel.  Standard control voltage is 120 V.A.C. with all wiring (internal of panel and external to devices) installed per N.E.C / NFPA.  PCT uses quality/reliable standard brand components available nationwide.  Applied voltage: 460-3-60.

 

Processor: Allen Bradley. This unit allows future expansion if desired. In the event desired future expansion exceeds the supplied number of I/O, it may be necessary to upgrade the system or purchase another model with additional capacity/features. PCT can provide a proposal for any upsizing desired based on customer’s detailed request.

 

Disconnect: fusible type or circuit breaker installed in panel for lock-out / tag-out

 

Contactors and motor starters: AB or AD with circuit breakers and/or fuses

 

Alarm Indicators: Visual light beacon mounted on top of main control electrical panel and audible alarm in panel door.

 

Program Software: Standard – loaded into processor.  PCT furnishes one initial operational program and one copy of this program on disc with one print copy of logic. Customer is responsible for any program software and programming terminal/lap top for future use.

Operation:

 

The tank and still system as proposed can operate as a batch system or it will operate continuously as long as there is a continuous supply of “dirty” solvent to be processed. Either the dirty solvent tank low level sensor or the clean solvent tank high sensor can shut down the still. When either tank reaches a high or low level an alarm light will be activated.  System must be physically restarted after the low or high level condition has been physically corrected.

 

Closed Loop Chilled Water System:

 

Process Cycle:  When water is used as the cooling medium in any system such as degreasers, distillation units (stills), carbon absorbers, etc, it absorbs the heat from the process side and can only be reused if the absorbed heat is dissipated.

 

The chilled water system accomplishes the heat removal by exposing this heated water to a much lower temperature inside a refrigeration cooled heat exchanger (chiller barrel). The chilled water system provides the “location” for this transfer of heat from the recirculating water to the refrigerant liquid being pumped by the systems’ compressor through the chiller barrel. The recirculating refrigerant absorbs the heat from the water and then gives up this heat through the air cooled condensers of the chiller compressor system into the ambient atmosphere.

 

The capacity of a chilled water system operating within its gallons per minute range is dependent on two external factors. These are inlet water temperature and the efficiency of the refrigeration system removing the heat. The larger the difference between entering water temperature and capacity of the refrigeration system, the higher the exiting temperature of the chilled water returning to the process equipment will be.

 

The amount of water to be chilled is based on a 10 degree temperature decrease between entering and exiting water, thus the requirement for an increased flow rate. A typical chilled water system’s capacity size for heat removal is twice as much as conventional cooling tower systems. The recirculation flow rate for the process water is also generally twice as much.

 

Typical systems consist of an internal or external mounted air cooled compressor unit, generally located in close proximity to the indoor receiver tank.  The chilled water is transferred through the process equipment by the recirculation pump, it absorbs the heat, and then is discharged into the receiver tank where the heated water mixes with the chilled water, and then is pumped through the chiller barrel by a second pump (on a dual pump system), releasing its heat, and returning to the receiver tank. The effect of the heated water being exposed to a much lower temperature of the refrigerant inside the heat exchanger causes the recirculating water temperature to drop. The mixing action of the two water streams in the reservoir tank also tends to lower the total water temperature.

 

During long term operation, a certain amount of the water will be evaporated or possibly seep out, and will need to be made up from an outside source.

 

  • The indoor reservoir tank is insulated and equipped with recirculation pump(s). On a dual pump system, the first pump recirculates the water from the reservoir to the chiller and back into the reservoir. The second pump transfers the water from the reservoir, through the process equipment, and back into the reservoir. The use of dual pumps, each dedicated for a specific duty, increases the efficiency of the operation as well as allows for more finite control of the process parameters.

  • PCT strongly recommends all recirculating water lines be insulated to maintain maximum efficiency as well as reduce ambient condensation.

  • This method allows for reuse of the cooling water and reduces the amount of water used through normal single pass through applications. The cost of the equipment is recovered through water conservation. The ROI will be based on the amount of water currently being used and the current price per gallon.

 

  • Each application is process specific and should be addressed by a knowledgeable party when selecting the correct method to suit the requirements. PCT is pleased to offer free technical consultation in regards to sizing a chilled water system to match your process equipment and provide an estimated ROI for the selected system based on the current local water cost.
