While SCI has been providing cutting-edge technical solutions to the oil & gas industry for more than 20 years, production companies are currently showing a lot of interest in taking control of their chemical costs through highly accurate monitoring, control, and pump by exception programming.
These control features are delivered via a chemical injection skid that can be customized and integrated into the existing process, and will work with the existing instrumentation onsite, whatever it may be.
Chemical Injection Skid Features Include:
Reduce Chemical Costs / Saving Time & Money
– Chemical optimization
-Controlled Injection Volumes and Inventory
-Verified delivery of product at the Injection Point
– Track Chemical with flow meters that are highly accurate down to 0.00105669 quarts
Monitor Chemical Tank Levels
-Tank Level
-Tank Gain and Loss values daily
– Built in alarming
-Low Level Alarms (alerts to when we need more product)
-Loss of Level Alarm (alerts if X amount of volume is removed in Y amount of time)
-Tank leak detection
-Pump fail to run
-Injection not sensed at injection point
-Meter No Flow alarm
Valve Control
-Ability to control or monitor production valves status to only inject when needed
H2S
-Ability to add an In line H2S analyzer to actively inject H2S chemical based on a live reading and a Ratio setpoint.
Pump Productivity
-Pump run-time (compare against meter total, use for preventative maintenance)
– Pump Control Modes
-Batch Mode
-Continuous Mode
-Rate Mode
-Ratio Mode
– Reduce number of pumps on one location
-Utilize pump to cycle through multiple injection points
– Built in back-up
-Can trigger a backup pump if first pump fails to run
-Use meter to accurately measure product injected
-Daily, Weekly, Monthly Totals per each point of injection
Plug Chemical Injection Skid into existing PLC , Control System, Panel RTU
– Modbus RTU
– Modbus TCP/IP
– Preprogrammed and read to go
– Customize skid to work with your existing hardware (panel, pump, power source)
– We can help install if needed
Communication Options
– Serial
– Ethernet
– Radio
– Cellular
Data Options
Integrate into HMI of your choice (Cygnet, ClearScada, WonderWare, FactoryTalk, etc) for trending, reporting, alarming, etc.
Other programmable Options:
– RTD to monitor Ambient Air Temperature to Automate Methanol Injection
– Cold weather control
– Monitor temp
– Skid battery voltage, (useful for solar applications)
– Current Transmitter on electric pump to monitor Amp draw and verify run status
– Pressure Transmitter at the injection point to ensure product made it to that point
