Chemical Injection Packages (or Chemical Injection Skids) are used to inject a precise and accurate amount of chemical into a system at a required pressure either continuously or intermittently
Chemical injection packages are assembled bringing the following components together.
Galvanized Carbon Steel or Stainless Steel structures complete with drip pans are projected to accommodate tanks, pumps, instruments and auxiliaries.
Materials utilized: Painted Galvanized Carbon Steel Stainless Steel.
Suitable to store chemicals our tanks are projected and manufactured according to ASME VII Div.I with U-stamp when needed and Roark & Young stress analysis.
Material of construction: SS304, SS316L, Carbon Steel, Plastic, FRP, GRP or CS +PTFE coating upon request.
ASCO provide a wide range of pumps.
Dosing pumps utilized according API 675 IIIrd ed. and reciprocating pumps according to API 674 Pump are the most common utilized pumps.
Flowrate variation can be either by manual stroke adjustment, automatic 4-20mA, pneumatic 3-15 psig, VFD or Flow control valves giving our customer the widest variety of choice.
Each chemical injection skid is provided with set of valves and instrumentation for different operation and application.
The most common used instruments are: level gauges, pressure transmitters, flowmeters, pressure gauge etc.
Isolation valves and check valves are usually selected in full compliance with Piping Specifications.
Suction and discharge lines studied to give the best solution in terms of NPSHa and Fluid velocity are commonly provided with isolating, drain, check valves usually selected in full compliance with Piping Specifications.
Suction line are completed with Calibration Gauges and Discharge lines with Pulsation Dampers and Pressure Relief Valve to ensure the most safe operations.
Materials: SS304, SS316L, PVC-C, PP, PVDF, CS, CS PTFE coated, HAST-C.
All signals are terminated into skid mounted junction boxes.
All controls like pump running local/remote indication, local start/stop of the motor, remote start/stop of the motor, remote stop, Emergency stop of the complete system, process trip and any other controls can be implemented from local control panel.
All electrical components are certified as per the area classification requirements.
