Details

Tittle:
Licensing of advanced petrochemical technology for the production of Maleic Anhydride ex N-Butane or Ex-Benzene
Summary:
An Italian company leading in process engineering design has developed new technologies to obtain optimum plant performances and limit the environmental impact. The SME has developed a Maleic Anhydride (MAN) process, an important intermediate for the production of lubricant oil additives, copolymers, agricultural chemicals, food additives, special anhydrides and alkyd resins. The company offers license agreement with technical cooperation.
Description:
The company born and raised in Rome-Italy, with a history that lasts for more than 45 years has developed this innovative product produced by a catalytic partial oxidation of vapor N-Butane or Benzene in a fixed bed reactor using the oxygen contained in air.

The primary chemical reaction are respectively the following:

N-Butane C4H10 + 3.5 O2 ¿ C4H2O3 + 4 H2O
Benzene C6H6 + 4.5 O2 ¿ C4H2O3 + 2 CO2 + 2 H2O

The main side reaction is the total oxidation of the raw material to produce CO and CO2, but other by-products are produced in small
quantity. The reactor conditions are optimized to maximize the Maleic Anhydride production, minimizing the by-products. Since the reactions are exothermic, the generated heat is used to produce steam, which is used in the plant and can be also exported to other users.
The reactor effluent stream is cooled, producing other steam, and
sent to the recovery section, where Maleic Anhydride is absorbed by a selective organic solvent, which is easily available on the free market.
Crude Maleic Anhydride is recovered from the solvent in a stripper
and then further purified in a continuous distillation system.

A portion of the recycled solvent is treated in a simple solvent purification system, where the impurities are removed. After Maleic Anhydride removal, the gas coming from the Maleic Anhydride recovery section is sent to an incinerator, producing flue gas and heat, used to produce steam. Only in the process from N-Butane, a fraction of the gas coming from the recovery section can be recycled to the reactor to improve the overall yield of conversion of N-Butane.
For small capacities, the company has also the know-how to implement in its plant the water recovery system.

The cooperation types that the company is lookig for are: License Agreement with technical cooperation.
Advantages and Innovations:
The innovation offered by the company is a gas phase catalytic oxidation process using normal butane (or benzene) as feedstock Thanks to an advanced reaction system integrated with a patented process of recovery and purification, the technology can be regarded as highly advanced and modern.
The technology of reaction has been substantially improved resulting in better yields and high productivity.
The recovery and purification system employs a readily available solvent and adopts unique features which result in high yield of recovery, low energy requirements, no regular shutdown and clean-outs, minimum environmental impact and high and consistent quality of the product.
Main advantages and innovations of the product proprietary technology are resumed here below:
- Lowest feedstock (n-butane) consumption (off-gas recycle patented technology)
- High Maleic Anhydride recovery efficiency (solvent recovery patented technology)
- Low energy and water consumptions
- Zero liquid effluents
- 40% reduction of gaseous effluent
- Continuous operation
- Safe Design
