Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called " trivial names " e. Esters derived from more complex carboxylic acids are, on the other hand, more frequently named using the systematic IUPAC name, based on the name for the acid followed by the suffix -oate. For example, butyl acetate systematically butyl ethanoatederived from butanol and acetic acid systematically ethanoic acid would be written CH3CO2C4H9. Cyclic esters are called lactonesregardless of whether they are derived from an organic or an inorganic acid.

With ProSimPlus Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called " trivial names " e.
Chemical Compatability | Rubber | Elastomer Drying[ edit ] PET is hygroscopicmeaning that it absorbs water from its surroundings.
Ester - Wikipedia Thus, before the resin can be processed in a molding machine, it must be dried. Drying is achieved through the use of a desiccant or dryers before the PET is fed into the processing equipment.

The syngas can be provided by a gasifier e. The different steps are modeled: The synthesis reactor is modelled using Gibbs energy minimization. Example of use of an external optimization algorithm This example illustrates the use of an external optimization algorithm in the ProSimPlus simulation environment.

The communication interfaces with the external algorithm are detailed along with a short application example. Operating balance optimization of a natural gas liquids plant This example presents the optimization of an existing natural gas liquids plant operating balance with ProSimPlus.

Simulation of a vacuum distillation unit This example illustrates the simulation of a vacuum distillation unit with ProSimPlus.

Simulation of an atmospheric distillation unit This example illustrates the simulation of a crude oil atmospheric distillation unit with ProSimPlus. Simulation of an atmospheric distillation unit with a preflash column This example illustrates the simulation of a crude oil atmospheric distillation unit with a preflash column with ProSimPlus.

ProSimPlus loads parameters from an Excel file and exports simulation results to the same Excel file. CO2 capture using an amine solution View This example presents the simulation of a CO2 capture process by absorption using an amine solution. The flue gas is first cooled in a direct contact cooler with water before to be CO2 impoverished in an absorber absorption column using an amine solution.

The amine is then regenerated in a desorber distillation column to be reused in the absorber. The desorber gas outlet composed of CO2 and water is then cooled and put in a drum to separate water from CO2.

Economic evaluation of a toluene hydrodealkylation process View This example presents the economic evaluation of a toluene hydrodealkylation process with ProSimPlus. The hydrodealkylation reactor is fed with pre-heated hydrogen and toluene.

The products of the reaction benzene, biphenyl and methane and the residual reactants are separated by a flash and three separation units. The recycling allows to reinject a part of the residual reactants into the hydrodealkylation reactor. LPG recovery unit using propane refrigeration.

This process is particularly inter-connected and includes several recycling loops. Additionally, beside the implementation of the absorber module and of the refrigeration loop, this process uses a brazed plate-fin heat exchanger. ProSec allows taking into account the effect of the stacking and of the pressure drop on the enthalpy curves.

Natural gas deacidification with the Selexol process View This example illustrates a natural gas deacidification with the Selexol process.

Selexol, mixture of polyethylene glycol dimethyl ether, is used as the solvent. The deacidification is done through a contactor and the solvent regeneration needs three successive flashes. The process objective is to highly decrease the CO2 composition of the input gas.

Selexol make-up is automatically calculated with simple modules. This example is taken from [RAN76] publication which describes main features of this process. Gas deacidification with a purisol process View This example illustrates a gas deacidification of a hydrogen stream with the Purisol process.

NMP make-up is automatically calculated with simple modules. This example is taken from [KOH97] publication which describes main features of this process.

Syngas deacidification with the Rectisol process View This example illustrates a syngas deacidification with the Rectisol process. Methanol is used as the solvent. The deacidification is done through a contactor and the solvent regeneration needs several columns and flashes.

The process objective is to refine a syngas of CO2 and H2S in order to have a satisfactory purity in CO2 allowing its storage and a stream of H2S able to be treated in a Claus unit.

Methanol make-up is automatically calculated with simple modules. Claus Process This example corresponds to the simulation of the well-known Claus process.Polyetherether Ketone (PEEK) Chemical Compatibility Chart: Check the chemical compatibility of PEEK with various chemicals, solvents, alcohols and other products..
