All About: Chemical Injection Skids

Chemical Injection Skids

A chemical injection skid is a specialised system that is used to accurately and safely deliver chemicals into a process or pipeline. These systems are commonly used in the oil and gas industry, as well as in other industries where chemicals are used in the production process.

A chemical injection skid consists of a series of pumps, tanks, and control systems that are designed to deliver the chemicals to the desired location. The skid is typically mounted on a frame or base, which allows it to be easily transported and set up in different locations.

The pump is the main component of the chemical injection skid and is responsible for moving the chemical or fluid from the storage tank to the point of injection. The pump can be a positive displacement pump, such as a diaphragm or plunger pump, or a centrifugal pump. The type of pump used will depend on the specific requirements of the application, including the viscosity, corrosiveness, and flow rate of the chemical or fluid.

The motor is used to power the pump and can be an electric motor or a gasoline or diesel engine. The motor is typically mounted on the chemical injection skid and is connected to the pump through a coupling or belt drive.

The structures on a chemical injection skid include the frame, supports, and any additional equipment, such as valves or filters, that may be required for the specific application. These structures can be made from a variety of materials, including steel, aluminium, or fibreglass, depending on the chemical or fluid being injected and the operating conditions of the skid.

Instruments are used to monitor and control the injection process and may include flow metres, pressure gauges, and control valves. These instruments allow the operator to adjust the flow rate and pressure of the chemical or fluid being injected to ensure that it is being delivered at the correct concentration and at the right location.

Tubing in the skid is used to transport the chemical or fluid from the storage tank to the point of injection and can be made from a variety of materials, including PVC, stainless steel, or Teflon, depending on the chemical or fluid being injected and the operating conditions of the skid. The tubing can be attached to the pump and other components of the chemical injection skid using fittings and connectors.

Chemical injection skids are used for a wide range of applications, including corrosion prevention, scale prevention, and pH control. In the oil and gas industry, for example, chemical injection skids are used to deliver inhibitors and other chemicals to prevent corrosion in pipelines and other equipment. In water treatment plants, chemical injection skids are used to deliver chemicals such as chlorine and sodium hypochlorite for disinfection purposes.

There are several different types of chemical injection skids that are used in different applications. One common type is the metering pump skid, which uses a metering pump to deliver precise amounts of chemicals at a consistent rate. Another type is the diaphragm pump skid, which uses a diaphragm pump to deliver the chemicals. Both of these types of skids are commonly used in the oil and gas industry.
