The following list will briefly discuss each of the major components of a typical chemical injection system. Depending on their purpose and physical setting, different chemical injection systems may vary, however, most employ each of the following in some way:
Tanks – Tanks are one of the most fundamental aspects of any chemical injection system because they required to store the chemicals which need to be injected into the system. Tank size and structure may vary, but typically they will be horizontal and cylindrical. They may feature a flat, conical, or dished bottom with a flat or dished top.
Pumps – Pumps are another fundamental aspect of chemical injection systems because they provide the source for generating the flow the pressure required to achieve the system’s objective. Pumps may be of a diaphragm or plunger type and may feature a number of different power sources including electric motor, air operated motor, solar power motor, or solenoid driven motor.
Valves and instrumentation – Valves and instrumentation are needed to measure and monitor what is going on within the system. For instance they will often monitor the liquid level inside the tank, allow for the calibration of the flow rate, monitor and adjust the pressure within the system, and set off alarms and other fail safes designed to ensure safety and proper function. Specific gauges and valves may vary depending on the exact purpose of the chemical injection system and the client’s own unique set of requirements and needs.
Electrical – A chemical injection system’s electrical system provides a way for the system to be started or stopped either locally or remotely. Typically the various controls and functions will be routed to a control panel for ease of use and function.
Skid Structure – All skid mounted chemical injection systems will also of course feature a skid structure as part of their fundamental component parts. The skid structure provides the structure itself for the system and is designed in such a way to protect the system while accommodating its various parts. It will usually feature structural steel which has been continuously welded. Often it will also feature a drip pan designed to collect drained chemicals.
