Plants
All over the world, JOSEF MEISSNER GMBH & CO. KG stands for innovative technologies as well as quality in plant construction for the chemical industry and the industry of explosives. We support our customers with the engineering, supply, erection, and commissioning of complete plants, special units, or entire plant complexes within the range of our processes.
Our customers benefit from our special know-how, which is based on our own research and development work, decades of experience, and more than 600 successfully commissioned plants. Our processes are consistently further developed in order to realize exceptionally safe, economical, reliable, and environment-friendly plants.
We trust in a qualified and dedicated team. Our staff brings in experience and expertise. The constant dialogue with our customers along with transparency on all levels of our activities are the basis for individual solutions which we develop jointly with our customers.
This is how we would like to plan together with you for a successful and safe future.
TRINITROTOLUENE
TNT
2,4,6-Trinitrotoluene, produced either from Toluene or ortho-Mononitrotoluene with mixed acids, mainly serves for military purposes and to a minor degree is also used in dynamite production.
Along with the equipment for nitration, sulphitation, drying and granulation, MEISSNER offers complete TNT plants also including an acid reconcentration plant and a waste water regeneration plant. The MEISSNER TNT process is characterized by the application of the countercurrent principle from one nitration step to the other, each nitration step constituting a separate unit, though. As a consequence, the qualities of the intermediate products Mononitrotoluene and Dinitrotoluene as well as of the product 2,4,6-Trinitrotoluene meet the high demands of military uses.
OCTOGEN, HEXOGEN, NITROPENTA
HMX, RDX, PETN
Octogen, presently the most powerful high-efficiency explosive, is produced from Hexamethylenetetramine according to the Acetic Acid process, and is used for special military purposes.
Hexogen can be produced either by the Acetic Acid process or according to the conventional Nitric Acid process, and is mostly processed to Compound B.
Nitropenta, a Nitric Acid ester of Pentaerythritol, is obtained by the Nitric Acid process. Apart from military applications, Nitropenta is mainly used in the civil explosives industry to be processed to detonating cords, and it is an essential component of detonating caps.
MEISSNER supplies complete plants for these explosives using the processes mentioned above, as well as plants for their further processing to Compound B, Octol, plastic explosives, etc.
NITROGLYCERIN AND NITROGLYCOLS
NG, DNG, DEGDN, TEGDN
Nitroglycerin and Nitroglycols are produced from the respective alcohols with anhydrous mixed acids by means of the MEISSNER injector process and are used for military purposes (propellants) as well as in the civil explosives industry (dynamite).
MEISSNER injector plants are characterized by on-line mixing of the acids (mixed acid store not necessary), small production quantities in the nitration cycle, dynamic separation of the product from the spent acid, and automatic discharging in case of power outage or shutdown.
Along with the complete injector plant, MEISSNER offers the corresponding equipment for the transport of Nitroglycerin/Nitroglycol (emulsion transport), for the storage (emulsion store), and for the weighing process.
Together with plants for the production of Nitroglycerin and Nitroglycols, MEISSNER as main contractor also offers acid regeneration plants.
MEISSNER also supplies plants for the production of dynamite and propellants.
NITROCELLULOSE
NC
The nitration (esterification) of Cellulose with a mixture of Nitric and Sulfuric Acid was discovered in the mid-19th century by the German chemist Schoenbein. The special properties of Nitrocellulose (NC) soon found wide application, e.g. in the explosives industry, and led to Nobel's development of dynamite.
Still today, Nitrocellulose is an important ingredient of explosives mixtures, such as propellants like single-, double- and triple-base powders as well as rocket propellants, or the above-mentioned dynamites.
The process as offered by MEISSNER is the result of long-standing development work and decades of experience in the manufacture of all grades of Nitrocellulose.
The main features of this highly modern Nitrocellulose process are:
continuous nitration
recovery of adhered acids
efficient absorption of nitrous fumes
application of a heat-recovery system
application of the latest refiner technology
continuous dehydration and alcoholization of Nitrocellulose
highest safety standards
improved product qualities.
The flexibility and efficiency of the process allow for the production of all grades of Nitrocellulose and perfectly combine economic efficiency, safety, and environmental aspects.
