Products
Methanol
In the modern world, methanol is one of the most significant industrial products.
In chemistry, this is the simplest monohydric alcohol — CH3OH.
Methanol is a clear liquid with an alcohol smell. It is also called wood alcohol, it can be obtained from coal, natural gas - from everything that was once a plant. It occurs naturally and is produced in small amounts even in the human body.
In modern industry, methanol is an indispensable product. It is used to produce hundreds of everyday products. Another purpose of methanol is the production of environmentally friendly fuel. This is why it is called the fuel of the future - it can replace oil products.
Methanol belongs to Class 3 Dangerous Goods (moderately hazardous). It decomposes rapidly under both aerobic (in the presence of air) and anaerobic (in the absence of air) conditions, in fresh and salt water, groundwater, sediments and soils.
Many bacteria can grow through the use of methanol. It is this property that is used in the process of treating industrial and domestic wastewater. Denitrifying bacteria at wastewater treatment plants are fed with methanol.
Methanol does not accumulate in biological environments. It is only poisonous if ingested, but not as toxic when inhaled.
One of the common myths is that «when methanol enters the atmosphere, formaldehyde is formed»
This is possible only in laboratory conditions, at a temperature of at least 650 degrees, the presence of a silver catalyst and atmospheric pressure. It is impossible to imagine such conditions outside the laboratory.
- at the first stage, exclusively methanol production is being set up at NFP: methanol will be obtained from natural gas via three-stage reforming — gas processing with water vapor
- the resulting gas mixture is then distilled to obtain pure methanol
THE PRODUCTION PROCESS UTILIZES ONLY:
natural gas (methane)
water
carbon dioxide
NO INTERMEDIATE PRODUCTS ARE CREATED AT THIS STAGE
- when designing NFP, even unlikely situations in which methanol could be released into the environment were estimated
- calculations revealed that if 10 thousand tons of methanol entered the open sea, then within the first hour after the accident, its concentration in water would amount to 0.36% only, and over the next hours it would decrease significantly; if methanol gets into the soil, with abundant watering methanol will biodegrade within a few days
The NFP project foresees emergency situations and methanol leakage is practically impossible. Tanks with the finished product will be placed in special concrete pools, from which methanol will be instantly pumped into neighboring tanks.
The smallest leak will be instantly reported by highly sensitive gas sensors. Operators identify a potential threat long before it starts.
Carbamide
Carbamide is the most common and most valuable nitrogen fertilizer.
Carbamide is used as a base of plant nutrition and pest control liquids. Carbamide can be found in chewing gum, flour, and even toothpaste.
In modern industry, methanol is an indispensable product. It is used to produce hundreds of everyday products. Another purpose of methanol is the production of environmentally friendly fuel. This is why it is called the fuel of the future — it can replace oil products.
The annual global sales volume amounts to
165 million
tons
of carbamide
According to experts, in the coming years, the demand for it will continue increasing.
The price of organic fertilizers -
due to the demand for safe food products - will also be stable
Global carbamide production
China
43%India
13,5%The synthesis of carbamide (NH2)2CO can be broken up into two stages, as follows:
- first, carbamic acid ammonium (carbamate) is produced via the following reaction: CO2 + 2NH3 -> NH2 – COONH4 + 150 kJ
- at the second stage, the carbamate is dehydrated and carbamide is obtained: NH2 – COONH4 -> CO (NH2) 2 + H2O – 258 kJl.
Chemical processes take place in a thick-walled column. The carbamide solution is evaporated and then crystallized; the crystals are separated from the stock solution in filter equipment or granulated. After distillation, gases are dispatched for regeneration and further use for new production.

Such technologies are able to ensure a minimal impact on the environment.
A number of requirements are imposed on the storage of carbamide, and NFP ensures full compliance with them: closed, well-ventilated warehouses, indoor storage of fertilizer containers. Carbamide is not classified as dangerous goods under the strict regulations of the European Fertilizer Manufacturers Association (EFMA)
