Standard Chemical Injection Skids
Standard Chemical Injection Skid is intended for dosing liquid demulsifies and corrosion inhibitors into the pipeline of industry’s transport system. This operation is a part of oil’s preparation for oil piping de-emulsification. Also standard chemical injection skid is render possible several pipeline protection measures, including anticorrosion protection and salt/carbonate/paraffin deposition control.
Usually standard chemical injection skid has a mono-block construction, arranged on a welded frame.
Various ways of construction are possible in accordance with the conditions and specialties of the customer’s task.
Multipoint chemical injection skids
Multipoint chemical injection skids are more suitable when the number of injection points is more and there is a space constraint to accommodate the skid foot print. The value proposition of this product is direct cost reduction in the capital investment, as one single skid replaces multiple chemical injection skids. The operating cost is much lower in this option as the maintenance cost is less and the floor utilization is maximized.
This type of system is best suited for offshore platforms where there is always a space constraint and the need for injecting different chemicals at different locations, pressure and flow. All these requirements can be achieved in one system by using compartmental tanks for storing different chemicals and by using different pumps with number of flow control devices to inject different chemicals at different pressures and flow rates.
MuIti -CompartmentaI Chemical Injection System
This type of Chemical Injection Skids is most suitable at offshore platforms where there is severe space constraint and a need for injecting different chemicals in the same location. Multi compartmental tank skids are mostly combined with multi-point or multi-pump injection systems. Different type of chemicals can be stored in different compartments of the rectangular tank which can be placed on the same skid base frame. Each compartment of the tank shall have separate set of pumps (single or multi head), valves and instruments. Controls for the whole system can be integrated into one system.
Multi-Head Pump Chemical Injection Skids
Diaphragm or plunger type Multi-head pump can be used to inject two or more liquids through one pump. The pump employs a single drive mechanism coupled in parallel with multiple pumping chambers, each capable of handling different types of chemicals. Instead of using several pumps for pumping different chemicals, one single pump with number of heads can be used. The pumps are precisely designed to make sure dosing of different chemicals in the required ratio. Its compact design demands less maintenance.
