NITROGLYCERINE & EXPLOSIVE OILS NITRATION PLANTS
NITROGLYCERINE TRANSPORT & WEIGHING

Nitration plants for most of the explosive oils, from NG (Propellant grade, Pharmaceutical or Dynamite grade) to EGDN, DEGDN and also TEGDN, MTN, BTTN.
The continuous process allows constant reaction conditions (such as temperature, raw materials ratio) thus ensuring constant product quality and stability.
These plants are completely automated; the reaction temperatures, the reagents’ feeding, the speed of the stirrers are all automatically controlled, as well as plant's start, shut-down, the displacement of explosive, spent acid and waste water.
Depending on the product to be manufactured, the plant can be equipped with different purification steps in a battery of stirred washers and separators, where it is purified with water and alkaline solution.

The nitroglycerine is safely transported with a water injector, from the manufacturing plant to the weighing section.
NG is separated from the water (which is recycled), weighed and sent either to the gelatine preparation or to the paste preparation plant.   To produce gelatine, NG is inertized by a solvent and sent by gravity to the planetary mixer for gelatine preparation.
If Paste is required, NG is sent again by water injection to the paste preparation section.
The scale is automatic and remotely controlled; all controls, signals and valves are pneumatic or, if electric, intrinsically safe.
