What type of pump is used for chemical injection?

Pneumatic or gas driven injection pumps Metering type pumps can be used for chemical injections as well as water. They can work at high pressures and allow for continuous flow rates to be averaged over time.

What is water injection pump?

Water injection pumps are used to force water, wastewater, waste field oil, and brine deep underground into porous formations. Injection can be used as an enhanced oil recovery (EOR) method in reservoirs where pressures are dropping.

How do you size a chemical injection pump?

With that in mind, a metering pump should be sized so that the maximum expected flow rate is 85% to 90% of the pump’s capacity, which will leave room for additional capacity, if needed. The minimum capacity should never be less than 10% of the pump capacity to maintain accuracy.

What is a chemical metering pump?

Chemical metering pumps dispense liquids at precise rates. Also known as dosing pumps, they can handle harsh and hazardous fluids such as bases, slurries, and corrosives. Chemical metering pumps dispense liquids at precise rates.

What is chemical injection?

Chemical injection is a process whereby secondary chemical solution is added to the primary process flow to improve the primary fluid quality or to enhance the flow of primary fluid. This process helps in the improvement in the production capacity, efficiency and reduction in the downtime.

How do water injection wells work?

Used in onshore and offshore developments, water injection involves drilling injection wells into a reservoir and introducing water into that reservoir to encourage oil production. While the injected water helps to increase depleted pressure within the reservoir, it also helps to move the oil in place.

How many types of dosing pumps are there?

4 different types
There are 4 different types of dosing pumps designed based on their action and pumping mechanism: Diaphragm-Type Constant Injection Pump – This is a pump chamber filled and emptied by a piston. It has a diaphragm and inlet and outlet valves.

How do I choose a dosing pump?

Typical specifications to consider when selecting dosing pumps are flowrate, pump head, pressure, horsepower, power rating, and operating temperature.

How do you calculate flow rate of dosing pump?

  1. Well Pump. FLOW RATE X. (gpm)
  2. Required. DOSAGE X. (ppm)
  3. Time. 1440 ÷ (min/day)
  4. Solution. STRENGTH = (ppm)
  5. Required. FEED RATE. (gpd)

How do you calculate dosing rate in chemistry?

Chemical Feeding

  1. Chemical used, lbs per day = Flow rate, MGD x chemical dosage, mg/L x 8.34 lbs per gallon.
  2. Chemical, lbs/day = (Flow rate, MGD)(chemical dosage, mg/L)(8.34 lbs/gal)
  3. Chemical dosage, mg/L = (Chemical, lbs/day)/(Flow rate, MGD)(8.34 lbs/gal)
