To be able to ferment the hydrolyzate I obtained from 250 g L −1 SSB hydrolysis, a fed‐batch reactor with in situ butanol recovery was devised. The process was started with the hydrolyzate II and when good cell growth and vigorous fermentation were observed, the hydrolyzate I was slowly fed to the reactor.

A fed-batch reactor with cyclic high pCO2 polymer extraction recovered 92 g of butyric acid to produce a total of 213 g compared to 121 g generated in a control reactor. This recovery reduced EPI in the TPPB, resulting in both higher productivity (0.65 vs. 0.33 g L(-1) h(-1) ) and yield (0.54 vs. 0.40).

A batch reactor system for a proprietary ion exchange reaction allowed successful scale-up of an R&D system. EPIC designed the unit with limited knowledge of the end product. By understanding the sequence of operations, and not the full details of the client's process, we were able to fulfill the client's need for confidentiality.
Solution processes are widely used in both batch and continuous polymerizations with all processes extensively using agitation equipment such as in the polymerization reactors and product recovery operations. Solution Reactors: Both batch and continuous reactors use agitated vessels equipped with jackets and even some internal heat transfer .
The batch reactor is the generic term for a type of vessel widely used in the process industries.Its name is something of a misnomer since vessels of this type are used for a variety of process operations such as solids dissolution, product mixing, chemical reactions, batch distillation, crystallization, liquid/liquid extraction and polymerization.In some cases, they are not referred to as .
2. Semi-batch process: A semi-batch reactor of stirred type tank as shown in the Figure 4, often used for its own particular characteristics. In this type, all quantity of one reactant is initially put in the reactor, and then other reactants are continuously fed. Only flows enter the systems, and no leave, hence the system is an unsteady state.
Figure 1. The batch esterification process setup. The recipe for the process is complex, involving a rangne of process steps for reaction, reflux and storage, recovery, stripping, cooling and steam sparging as show in Figure 2. Figure 2. The batch esterification recipe. The bottom table shows that the batch time is relatively long.

In a control batch reactor the culture produced 17.6 g/L total solvents, while in the continuous integrated process and recovery by gas stripping, it produced 460.4 g/L total solvents (acetone 204.01 g/L, butanol 251.27 g/L and ethanol 5.08 g/L). The continuous reactor was operated and intentionally terminated after 21 .
Sequencing Batch Reactors DESCRIPTION The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single "batch" reactor, treated to remove undesirable components, and then discharged. Equali zation, aeration, and clarification can all be achieved using a .
The objective of this study was to increase nicotine recovery from tobacco leaves (Nicotiana tabacum) through pyrolysis using new technology, a mechanically fluidized reactor (MFR). The MFR is a cylindrical batch reactor, 15 cm in diameter and 25.4 cm in height.
Batch reactors generally demand some additional objectives such as: fast heatup or cooldown to a new set point without oscillation and with minimal overshoot; and . Figure 5 shows another example of nonlinearity: on the heating step, after the initial overshoot, recovery to 50° C was extremely slow due to the control-valve flow .
The flexible reactor design used together with the available characterization tools provide a high level of confidence that the project's technical objectives can be met. Phosphate release rates of the PAO-containing granules will provide essential information for full-scale design of a struvite fertilizer recovery .

A semi-batch reactor will have some addition and/or removal during the course of the reaction; a T-flask is a semi-batch reactor if media is changed between passages. Batch reactors can be operated as static or mixed; a T-flask is static (Fig. 3.1) and a stirrer flask, such as a Techne® Flask (Fig. 3.2) is mixed. Mixing helps remove .

One reason why our glass-lined reactors are trusted by over 90% of the world's top chemical companies is the sheer reliability of our reaction technologies. These technologies are critical to the safe containment of corrosive contents, maintaining the vessel pressure and ensuring the final batch quality.
The ANT Sequencing Batch Reactor (SBR) wastewater treatment system was installed on the R. C. Hunt farm in Bailey, North Carolina to treat half of the wastewater from 4200 pigs in six confinement buildings on the farm with a design capacity of 12,800 feeder to finish swine.

A Sequencing Batch Reactor (SBR) is often used in wastewater treatment plant whereby space availability is a constraint and cost of construction and setup is a major issue to keep the budget low. Unlike conventional continuous flow system, which has several separate process tanks, SBR only has one single reactor for all the working processes.Although the unit of operations between both setups .
In this study an anaerobic-anoxic SBR (sequencing batch reactor) was used in order to investigate the possibility of phosphorus removal utilizing nitrate as an electron acceptor, instead of oxygen in biological phosphorus removal processes.
