A multiple activation-device launching system for a cementing head comprises a launcher body and at least one launching chamber that are sized to receive one or more activation devices therein. The activation devices are launched into the principal process-fluid stream inside the cementing head, and
A multiple activation-device launching system for a cementing head comprises a launcher body and at least one launching chamber that are sized to receive one or more activation devices therein. The activation devices are launched into the principal process-fluid stream inside the cementing head, and may be darts, balls, bombs, canisters and combinations thereof. The launching chambers are in fluid communication with an external power source for launching the activation device into the principal process-fluid stream.

1. A multiple activation-device launching system for a cementing head, comprising a launcher body that comprises at least three unblocked launching chambers, each launching chamber sized to receive one or more activation devices therein, said activation devices comprising darts, bombs or canisters,
1. A multiple activation-device launching system for a cementing head, comprising a launcher body that comprises at least three unblocked launching chambers, each launching chamber sized to receive one or more activation devices therein, said activation devices comprising darts, bombs or canisters, each launching chamber in fluid communication with an external power source for launching the activation device, wherein the external power source is a fluid that flows through the launching chambers, wherein at least one activation device is filled with a chemical substance that is released after launching. 2. The system of claim 1, wherein each of the launching chambers are arranged at an angle relative to the axis of the launcher body. 3. The system of claim 1, wherein the fluid comprises drilling fluids, cement slurries, spacer fluids, chemical washes, acidizing fluids, gravel-packing fluids, scale-removal fluids and combinations thereof. 4. A method for deploying one or more activation devices into a process-fluid stream, comprising: (i) providing a multiple activation-device launching system for a cementing head, comprising a launcher body that comprises at least three unblocked launching chambers, each launching chamber sized to receive one or more activation devices therein, said activation devices comprising darts, bombs or canisters, each launching chamber in fluid communication with an external power source for launching the activation devices, wherein the power source is a fluid that flows through the launching chambers, wherein at least one activation device is filled with a chemical substance that is released after launching;(ii) installing the launching system on the cementing head;(iii) installing at least one activation device into at least one launching chamber;(iv) connecting each launching chamber to a fluid source that is independent of the process-fluid stream;(v) causing the fluid from the independent source to flow into the launching chamber, thereby injecting one or more activation devices into the process-fluid stream. 5. The method of claim 4, wherein the process fluid comprises drilling fluids, cement slurries, spacer fluids, chemical washes, acidizing fluids, gravel-packing fluids, scale-removal fluids and combinations thereof.
