Propylene from naphtha crackers (and FCC plants) is limited in quantity and expensive due to this, the use of natural gas-methanol-MTP (Methanol-to-Propylene Algorithm) synthesis technology is very competitive.
The production complex is based on the technology for producing propylene from natural gas through methanol (Methanol-to-Propylene (MTP).) The propylene produced can be used as a feedstock for various petrochemical processes.
MTP technology is fully tested. All stages of the process are fully tested. The resulting product is completely suitable for polymer synthesis.
The advantages of this technology are:
• Maximized propylene yield
• Possible production of ethylene for the production of copolymer
• Valuable by-products (Petrol, etc.)
• Small risk of production losses (sum of products)
• Special branded catalyst based on zeolite
• Fixed bed reactors (simple construction, easy scaling)
• Low coking of the catalyst
• Regeneration of the catalyst in situ at a temperature close to the reaction temperature
• Proven process elements
Combustion of APG (Associated Petroleum Gas) on flares leads to emissions of millions of tons of pollutants into the atmosphere. As a result of flaring of associated gas in our country, on average, one tonne of oil produced accounts for about 8 kg of emissions of harmful substances, which are localized primarily in production regions.
When burning APG, soot, nitrogen oxides, carbon monoxide, 3,4-benzpyrene, "slipped hydrocarbons", benzene, phosgene, toluene, heavy metals (mercury, arsenic, chromium), sulfurous anhydride and others form. It is also important that when APG is burned, greenhouse gases are formed that affect the climate of the planet (see theme "Greenhouse gases and climate change").
The thermal pollution from flaring of associated petroleum gas is also great, which is felt at a distance of up to 5 km from the flare unit and affects the meteorological and climatic conditions. Pollutants, after entering the atmosphere, are carried by the air flow in a gaseous, liquid and solid (aerosol) state. One of the main sources of air pollution in the regions in which the oil industry is developed and developed is the flaring of APG in flare plants.
According to some estimates, the total area of disturbed soils from the impact of burning flares is about 100 thousand hectares. Near the flares, as a result of exposure to high temperatures in a radius of 20-200 m, there is an almost complete burning of the organic matter of the humus-accumulative horizons, the structure and granulometric composition of the soils is changing.
In the case of burning or unburned (drip) oil in the flare emissions, the top layers of the soil are bituminized.
Chemical degradation caused by the entry into the soil of various compounds is manifested in the violation of geochemical balance, including carbon-nitrogen, in the change in the migration capacity of many macro- and microelements, in the inclusion of many toxic compounds in man-made flows. As far as the distance from the torch, the degree of transformation of the soil from the thermal effect decreases.
