 · 1. Introduction. Maleic anhydride (MA) is widely used to produce other chemicals such as polyester resins, food additives and pharmaceuticals. The production capacity of MA is expected to increase world-wide by 30% in 2020 compared to the year 2015 ().Approximately 70% of MA is produced by partial oxidation of n-butane over VPO (vanadium phosphorus oxide) catalysts; while the remaining … Particulate Solid Research Inc. (PSRI) is an international consortium of companies focused on the advancement of technology in the multiphase flows with granular and granular-fluid systems. Since 1971, PSRI has amassed a prolific amount of design data, technology, know-how, design criteria and models on all aspects of slurries, liquid injection, fluidization, entrainment, pneumatic conveying ...

In this project, the selective oxidation of benzene to maleic anhydride (MAN) was studied. Gas phase catalytic oxidation of benzene was carried out in a laboratory scale fluidized bed reactor on six different types of catalysts, which have different compositions. phthalic anhydride may be expected if phthalic anhydride were to be produced exclusively from a-xylene. Table I (29) compares the costs of phthalic anhydride produced from naphthalene in both fixed and fluidized beds with that produced from a-xylene in a fixed bed reactor. The advan­ tage of using a-xylene is apparent.

Production of Maleic Anhydride from Benzene Problem Statement We are now prepared for you to complete a final design of a production facility for maleic acid from benzene. You are to design a facility to produce 40,000 tonne/y of maleic anhydride. Chemical Reactions The raw material is benzene. The primary reaction is one in which benzene is ... Maleic anhydride is produced by oxidizing a straight chain C 4 hydrocarbon with oxygen in a stream comprising 25 to 60% by volume of the C 4 hydrocarbon, 20 to 45% by volume of oxygen and optionally inert gases to produce a stream containing at least 21/2% by volume of maleic anhydride and condensing maleic anhydride substantially free from water from this stream.

The oxidation of n‐butane to maleic anhydride over an industrial vanadyl pyrophosphate oxide catalyst was investigated experimentally in millistructured reactors with varying slit widths to investigate the process intensification potential of this reaction.Although the smaller reactor behaved isothermally, even in the presence of high n‐butane concentrations, moderate hot spots never ... From an economic point of view, maleic anhydride production cost is lower (60%) compared to that of the benzene process. The maleic anhydride grade is 99.9999%, as specifically required in some applications. There is an aqueous effluent reduction and process water reduction due to the use of patented solvent recovery.

Energy Recovery is a key factor in the economic production of maleic anhydride. Reactor off-gases, post maleic anhydride recovery, non-condensibles from vacuum systems, tank vent gases, and waste hydrocarbon rich liquids, are all incinerated to recover energy as super-heated steam. This steam can be used to supply energy to integrated units. Technobell’s Maleic Anhydride production process system consists of fixed bed reactor(s) with single or double salt layer circulation, continuous gas cooling, continuous product recovery systems by partial condensation and absorption, batch or continuous dehydrating and distillation/refining system and a continuous incinerator unit with steam turbine generator.

This feasibility study presents an analysis of Maleic Anhydride production from n-butane in the United States using a process similar to the one developed by Huntsman. In this process, maleic anhydride is produced by the partial oxidation reaction of n-butane with oxygen carried out in a fixed-bed reactor, using a vanadium–phosphorus oxide (VPO) catalyst supported on silica.
