CHEMICAL INJECTION SKID
FOR OIL AND GAS INDUSTRY
BY
ViENERG Resources Pvt Ltd
MAIN FEATURES AND SPECIFICATIONS
Chemical injection Skid are designed to inject
accurate amount of various chemicals into process
flow lines at a required pressure continuously or
at irregular intervals
SKID STRUCTURE
A Skid is basically a steel flat structure built to
carry tank, pump, motor, valves, instruments and
related auxillaries. The base structure of a skid is
integerated with drip pan to collect the drained
chemicals.
CHEMICAL STORAGE TANK
The chemicals are stored in skid mounted
single or multi-compartment tanks. Storage
tanks are constructed in horizontal cylindrical
or vertical cylindrical with flat dished bottom
and top. Tanks are provided to store the
chemicals , injected in the process lines. The
external effects such as heat, cold, pressure,
and vaccum may impact the tank ability to
hold and maintain the viability of both the
chemicals and container
DOSING PUMP
The Heart of any chemical injection skid is
Dosing Pumps. It is the source of a skid for
generating pressure and flow
VALVES AND INSTRUMENTATION
For Safe operation each chemical injection
skid is provided with set of valves and
instrumentation depend on their different
applications. Normally each skid is provided
with Pressure transmitters, flow meters,
level gauge,pressure gauge etc..
Level Gauge indicates level of the chemical
inside the tank. Level transmitter for
continuous monitoring the level of chemical
is too low or high, to avoid the damage of
pump..
Calibration pot is installed in the suction
line to calibrate the chemical injection flow
rate. Suction Pressure gauge helps to
detect the low pressure. Discharge
pressure gauge and pressure relief valve
helps to protect the piping line from over
pressurization.
Pressure transmitter helps to identify
pump performance and also system
integrity.Check Valves help to protect the
chemical injection skid from any back flow.
Flow Meters help to measure the flow rate
of chemical injection
ELECTRICAL
All signals are terminated in the mounted
junction boxes. All controls like pump running
local / remote indication, local on / off push
button of the motor, remote on/off push
button of the motor, emergency stop of the
complete process system and any other
controls can be implemented from the local
control panel.
APPLICATIONS
Corrosion inhibitor chemical injection
skids are used to inject appropriate corrosion
inhibitor chemicals into the system at regular
interval,to minimize corrosion of high valued
equipment and helps for extended life. It is
used to inject chemicals in major equipments
such as Heater Treater and Desalter.
A Scale Inhibitor Injection Skid to minimize
formation of scale in Heaters / Desalters.
Scaling will reduce performance efficiency of
equipment and plant production.
A Demulsifier Injection skid to Breaks down
oil emulsions to aid oil/water separation. In
heavy crudes it is very difficult to separate oil
and water. This skid is used to inject the
chemicals for de-emulsification which inturn
enhance the separation of oil and water.
Antifoam chemical injection skids are used to
inject antifoam chemicals into the test
separators to minimize foaming formation
and maintains clean flow of liquids and
improves separation efficiency , Foaming will
cause erratic readings which will reduce
system performance and ultimately affect the
production
