This type of chemical injection packages is most suitable at offshore platforms where there is severe space constraint and a need for injecting different chemicals at the same location. Different types of chemicals can be stored in different compartments of the rectangular tank which can be placed on the same package base frame. Each compartment of the tank has a separate set of pumps (single or multi-head), valves and instruments. Controls for the whole system can be integrated into one system. Package size and cost benefit can be better achieved in this package, compared with a conventional type of package.
