Optimisation of an esterification reaction

Optimisation of an esterification reaction

Specialty Chemicals
PROJECT DESCRIPTION Our client produces polymers by polyesterification on several sites all over the world. He wants to reduce esterification time by optimizing mixing of reactants and distillation of light products. This has to be done for each site. PROJECT METHODOLOGY Processium diagnoses the hydrodynamics regime of each reactor. Based on hydrodynamics regime and impeller design, Processium proposes other impellers. A sizing of each new impeller is proposed. Solutions are compared and ranked. A new impeller and its sizing is chosen with the client. Distillation mode are not the same, depending on the site. Especially, regulation mode are not the same. Processium proposes a standard of regulation mode to ensure process robustness. A new packing is also proposed, to ensure distillate quality. RESULTS The process is optimized via change of impellers…

<strong>Deinove announces the success of its cosmetic active ingredient’s production process industrialization</strong>

Deinove announces the success of its cosmetic active ingredient’s production process industrialization

news-processium
  DEINOVE (Euronext Growth Paris: ALDEI), a biotech company that discovers, develops, and produces high-value compounds from rare bacteria, notably from the Deinococcus genus, announces having produced the first industrial batch of its innovative carotenoid. As announced in December, the scale-up of the fermentation production process was carried out on the technological platform of the BIOGIS Center at SAS PIVERT. After a technology transfer stage, a first production of several cubic meters was successfully completed. The biomass produced followed an original and environmentally-friendly process, developed in collaboration with PROCESSIUM, for extraction, purification, and formulation, resulting in the first industrial batch of the end product. DEINOVE selected VEG’EXTRA, a specialist in extraction, as a provider for these downstream processing steps. Read more ...

Deactivation test on catalysts

Deactivation test on catalysts

Biotechnologies, Specialty Chemicals, Biomass Extraction
  PROJECT DESCRIPTION Our customer wishes to know the kinetic of deactivation of its catalyst under industrial conditions in order to adapt the sizing of corresponding process accordingly. In addition to this, the definition of the frequency of replacement of the catalyst was also an issue to secure productivity. TECHNICAL CHALLENGES Test should be performed continuously over hundreds of hours on a reactive mixture under conditions which precisely represent the operating conditions (temperatures over 250°C and pressures of 6 bar). The test needed to implement a dedicated bench to test the catalyst in continuous mode. OUR METHODOLOGY Design and development of a continuous reaction bench equipped with a tubular reactor working in conditions close to those of the process (6 bar and 250°C). Regular sampling from the reactor for 30 days.…

Deinove: the industrialization process of the carotenoids program enters Phase II

news-processium
  In November 2016, DEINOVE launched the shift from laboratory to industrial scale, accompanied by the company Processium* . The first phase of this program consisted of: Selecting and characterizing a first carotenoid that will be market-ready, validating both its biological properties and its economic potential; Optimizing the production strain and increasing the yields in the laboratory, with a view to obtaining a strain suitable for industrial production; Evaluating the various extraction processes in order to define the best one in industrial production conditions. This phase I has been conducted successfully. A first molecule has been selected for its innovative feature, with the goal of obtaining a competitive advantage on the market. DEINOVE has demonstrated its total safety, but also its antioxidant and healing properties, which position this first molecule…

Debottlenecking of batch process</strong>

Debottlenecking of batch process

Specialty Chemicals
PROJECT DESCRIPTION The Client produces ester in a batch process (reaction + distillation column). Processium services were requested to enhance unit productivity by decreasing the duration of each batch. Improvement of co-product quality is also requested and part of the Project. OUR METHODOLOGY The first task issued by Processium was a statistical study on process data issued from SNCC to identify the reasons for dysfunction among all parameters (quality of reactants, temperature, stoechiometry, …). This study highlighted several parameters responsible of malfunctions of the unit. Thanks to the management of these identified parameters during production, productivity increased of 5%. Following this first study, Processium conducted a new study based on kinetics and thermodynamics measurements, development of corresponding models and process optimization using ASPEN simulation. RESULTS Unit had been debottlenecked (10%) without…

Odour removal

Odour removal

Specialty Chemicals
PROJECT DESCRIPTION The Client uses distillation to purify an added value product. One of the impurity is an odorous molecule that causes two limitations: the product can not be supplied for specific application because of the smell given to the product by the odorous impurity, in order to limit the quantity of odorous impurity in the product, the yield of purification has to remain low. The Client asks to Processium to identify a technical solution to retain the odorous impurity  in the bottom of the distillation column. OUR METHODOLOGY To be able to propose technical solutions, Processium developed the following methodology: identification of a technical solution (bibliography, internal know-how), screening of existing activated carbons using in-house database including exhaustive data on possible suppliers, development of a design of experiments to minimize…

PROJECT DESCRIPTION The Client has developed a new process to treat a waste stream: possible unit operations are chosen, theoretical mass and thermal balances are available, theoretical sizing is also available, CAPEX and OPEX estimate is issued. The Client asks to Processium to challenge the developed process in order to secure its operability, its productivity and to minimize uncertainities during its industrialisation OUR METHODOLOGY For each unit operation, Processium studies: the relevance of the technology, its performances (expected yield and purity), Its limitations. The process, as a whole, is studied to fully understand the product specifications, the yield, and all process limitations. RESULTS Processium issued a recommendation report containing explanation on: an "alert" on impurity accumulation on a recycling loop, a risk of reaction on activated carbon, an uncertainty on thermodynamics (impact…
