  • 3. Journey
  • 4. Many new chemical, particularly batch operations, can be scaled up directlyfrom the bench to the plant by developing the process and performing labtesting with the scaleup in mind.MANY COSTLY AND TIME-CONSUMING startup problems can be avoided ifkey scaleup issues are understood and resolved during the development of a newchemical process.Processes are often scaled up in stages from the lab to the pilot plant or semi-works scale to obtain engineering data for commercial plant design.However, this staged scaleup strategy is not always practical for specialtychemicals, which are often characterized by multi-step batch syntheses andrelatively low volume, and where speed to market and rapid ramp-up areessential for commercial success.
  • 5. Scaleup is defined as "The successful startup and operation of a commercial size unitwhose design and operating procedures are in part based upon experimentation anddemonstration at a smaller scale of operation"(1). Many factors must be considered when selecting the scaleup strategy. Answering afew process-specific and business-related questions early is key to a successful startup. Process factors •What are the critical factors of the new chemistry and process? Are extreme temperatures, pressures or other conditions required? Are operating instructions complicated? * Does the process involve a single reaction, or is it a multi-step synthesis? If the last step in a multi-step process will be piloted, will it be necessary to also make intermediates at the pilot-plant scale, or are they commercially available?
  • 6. * Are new chemical technologies, unit operations orequipment being considered?* How novel is the new process? Have similar reactions orprocessing steps been successfully scaled up?* Will the new process be run in batch, semi-batch orcontinuous mode?Business factors* Does the commercial success of the project depend on aflawless initial production campaign?* Is there an alternative supply of material in case start-upproblems limit the production rate?* Are project economics sensitive to yield or to the ability torecover and recycle some of the streams at relatively highlevels?*
  • 7. What is the commercial timeline? Is there enough time todesign, build and operate a pilot plant to generate scaleupdata and still meet the planned commercial launch?* If the startup is delayed, what is the impact on the productlaunch strategy and project economics?* Are significant quantities needed for the launch of theproduct, or will it be introduced into the market slowly?* Are development samples needed over a period of timeleading up to the launch?* If a pilot-plant campaign is being considered, will thebusiness support the cost and human resources needed toperform this activity?
  • 8. Scaleup issuesSome of the most common and difficult types of problemsencountered during scaleup are particle formation andisolation, liquid/liquid separation, agitation, heat history andtrace impurities. (Reaction scaleup is widely discussed in theliterature and will not be covered here, and it is assumed thata sound chemical route has already been selected.) Often,scaleup problems are a combination of several of thesefactors (2).Particle formation and isolationSolids can form as a result of precipitation, often duirng areaction, or be produced intentionally, such as bycrystallization. Generally, the goal is to form large, uniformparticles, which will be filtered, washed and dried moreefficiently, and are of higher purity, than fine particles.
  • 9. In almost all cases, understanding and controlling theparticle growth environment will result in better particles(3).Many reactions are run in a semi-batch or continuousaddition mode, where one of the reactants is meteredinto the reactor and the product formed is a solid. Theorder of addition, rate of addition and feed location, aswell as the intensity and design of the agitation system,can all affect the particle formation process. It is alsoimportant to consider the physical aspects in addition tothe chemical aspects of the reaction, and how theseaffect the particle growth environment.
  • 10. Crystallization processes involve creating a state of supersaturation, typically bycooling, evaporation, chemical reaction or anti-solvent addition, which drivesnucleation and particle growth.These processes are governed by the conditions of the environmentimmediately next to the particle. A basic understanding of the solubility curveand supersaturation limit is quite helpful. Changing the solvent phasecomposition can have a significant effect on the solubility curve.Tools such as Fourier transform infrared (PTIR) spectroscopy, optical densityprobes, and microscopes are very useful for studying and optimizingcrystallization processes.It is a good idea to determine the crystal size distribution (CSD), shape,strength and whether multiple polymorphs exist. The latter is particularlyimportant in the pharmaceutical industry.

  • 18. Types of ReactorsBatch Reactor (BR, STR) The reactants are initially charged into the vessel and are well mixed and left to react for a certain period of time. The resultant mixture is then discharged. This is an unsteady operation where the composition changes with time but is uniform throughout the reactor at a specific time.
  • 19. Continuous ReactorsContinuous stirred tank reactor (CSTR, MFR, BMFR)  An agitator is introduced to disperse the reactants thoroughly into the reaction mixture immediately they enter the reactor.  Product is continuously drawn out and that’s why known for perfect mixing.  Compositions at outlet and inside reactor are same.  Best suitable for liquid phase reactions

  • 26. The type of resin to be used should be defined by the resin producer depending on the requirements.These ion exchange resins need to be regenerated periodically depending on water and resin characteristics. The productsregenerating these resins are caustic soda for the anion exchange resin and hydrochloric acid for the cation exchange resin.Regeneration processes must be defined by the resin producer, but, in general, three steps for the anion resin can bementioned:1.Backwash rinsing with water to eliminate fines and any particle coming from the water flow,2.Injection of a 4% aqueous caustic soda solution in Mg2+ and Ca2+ free water to avoid precipitation on the resin bed,3.Rinsing with about 3 times the resin volumes to eliminate the caustic soda in two progressive phases, a slow one toeliminate the greater part of the caustic soda and a fast one to eliminate the last residue.

Development of a Novel Catalytic Distillation Process for Cyclohexanol Production: Mini Plant Experiments andComplementary Process SimulationsRakesh Kumar†, Amit Katariya†, Hannsjörg Freund*†, and Kai Sundmacher†‡† Max Planck Institute for Dynamics of Complex Technical Systems, Sandtorstrasse 1, 39106 Magdeburg, Germany‡ Process Systems Engineering, Otto-von-Guericke University Magdeburg, Universitätsplatz 1, 39106 Magdeburg,GermanyOrg.

  • 46. A new, two-step process concept for the production ofcyclohexanol by indirect hydration of cyclohexene usingformic acid as a reactive entrainer is suggested, and itsprinciple technical feasibility is demonstrated. The first stepof this process is based on an ester formation reaction ofcyclohexene with formic acid. This reaction was carried outin a mini plant stainless steel catalytic distillation column of2.35 m height. The column was packed with noncatalyticstructured packings (SULZER-DX) and catalytic structuredpackings (KATAPAK-S). The experiments were conductedunder low-pressure conditions (<0.6 bar) to avoid formic aciddecomposition. Concentration and temperature profiles wereobtained under steady-state conditions.
  • 47. Up to 98.3% conversion of cyclohexene and 75.5 mol % esterconcentration in the bottom product of the column wasobtained. In a similar manner, the second step of theprocess, i.e. the hydrolysis of the cyclohexyl formate formedin the first step, was investigated experimentally in acontinuous catalytic distillation column under low-pressureconditions (<0.4 bar). Important process design parameterssuch as the feed mole ratio of the reactants, the reboilerduty, the feed flow rate, and the column pressure wereinvestigated with regard to their effect on the cyclohexeneconversion and the purity of the bottom product.Furthermore, the experimental data were compared withresults obtained from steady-state simulations of thecatalytic distillation process.
