Satanic Exorcism?

[Infernal Knight]

Is their a proper way to exorcise elemental or human spirit out of victim? No, not enemy possession but just an elemental spirits or some out of control deceased spirits.

The reason im asking about this because here in Philippines spirit possession is quite active. there even been a news about the "mass" possession (imagine more than 10 people possessed the same time) on some rural public elementary school while doing the flag ceremony. As Spiritual Satanist in case of i might encounter this bizarre situation what is the proper action i must take?

Hail Father Satan!!
Hail To All Gods of Duats!!
Hail To All Spiritual Satanist!!!
