Feasible and optimal retrofitting of batch‐soluble to continuous‐immobilized enzyme processes applied to adsorbed enzymes

Biotechnology and Bioengineering, 1985
AbstractThe advantages of retrofitting an in situ soluble enzyme batch process to an immobilized enzyme continuous process are contrasted against the disadvantages by means of a dimensionless feasibility/optimization analysis. The general analysis is applied to the case of an adsorbed enzyme system where a maximum in activity occurs with respect to ...

Process Modelling Tools for Continuous and Batch Organic Crystallization Processes Including Application to Scale-Up

Organic Process Research & Development, 2006
Computational fluid dynamics (CFD) is a powerful simulation tool that was successfully used to investigate mixing, turbulence, and shear in a laboratory-scale MSMPR and batch cooling crystallizer for an organic fine chemical. CFD gives a qualitative engineering insight into the effects of the impeller configuration on the crystallization rates and ...

Sets formulation to schedule mixed batch/continuous process plants with variable cycle time

Computers & Chemical Engineering, 1999
Effective scheduling of operations in the process industry has the potential to achieve high economic returns. Process plants containing both batch and continuous units present a difficult scheduling problem. When these processes are modelled with batch cycle times as decision variables, the complexity of the problem is increased significantly.

Sensors for biomanufacturing process development: facilitating the shift from batch to continuous manufacturing

Current Opinion in Chemical Engineering, 2018
The biopharmaceutical industry has traditionally utilized batch manufacturing strategies for production, but continuous manufacturing has been explored as an alternative production method in recent years because of the potential financial and quality benefits.

From Batch to Continuous Production Through Micro Process Technology: Chances and Challenges

ASME 2008 6th International Conference on Nanochannels, Microchannels, and Minichannels, 2008
The majority of the manufacturing processes in the chemical, pharmaceutical, food or cosmetics industry is operated as batch processes. This is economically advantageous in cases where - capacities per product are low, in the range of 10 kg/a to 1000 t/a - many different educts have to be mixed and processed for the product, i.e.

Batch and Continuous‐Flow One‐Pot Processes using Amine Diazotization to Produce Silylated Diazo Reagents

Angewandte Chemie, 2017
AbstractA novel synthesis of trimethylsilyldiazomethane (TMSCHN2) by diazotization of trimethylsilylmethylamine (TMSCH2NH2) is reported using batch and continuous flow synthesis. The latter affords a daily production of 275 g (2.4 mol) of TMSCHN2. Other silylated methylamines were also successfully reacted under the developed reaction conditions to ...

Selective Hydrogenolysis of Glycerol to 1,2-Propanediol: Comparison of Batch and Continuous Process Operations

Organic Process Research & Development, 2010
The screening of copper chromite catalysts with various promoters such as Al, Zn, and Ba for glycerol hydrogenolysis to 1,2-propanediol (1,2-PDO) in a batch reaction showed that Cu−Cr (Ba) catalyst gave the highest conversion of 34% and selectivity of 84% to 1,2-PDO.
