“…In a previous publication, 36 we had considered the production of 1,3-butadiene from a conventional naphtha cracker feed. Normal and turndown throughputs of 1,3-butadiene in the naphtha feed were 25 050 and 12 625 kg/h, respectively, based on values from BASF.…”

1,3-Butadiene is used in the production of commercially important elastomers. However, the sustained production of 1,3-butadiene is facing challenges due to the reduction in availability of heavier cracker feedstock. In this article, three different routes that utilize biomass to produce 1,3-butadiene and associated coproducts ethylene and propylene from lignin are explored. Steady-state simulation models are developed, and it is shown that, while all three routes are feasible, the yield of 1,3-butadiene is low in all cases. For this reason, it is necessary to consider the production of other useful products, such as ethylene and propylene, in an integrated plant that is used to make up the shortfall of 1,3-butadiene. The simulation models provide an estimate of the amount of lignin needed to produce additional 1,3-butadiene to augment the shortfall from a traditional 1,3-butadiene plant. Furthermore, the simulation models can be used to calculate the emissions of carbon dioxide and carbon monoxide.

“…The challenge in simulation is finding a suitable thermodynamic model. This subject was addressed in few papers. − Here, we use the NRTL model with binary interaction parameters from the Aspen v. 11 (DMF with 2- cis -butene and butadiene), NIST v. 11 (DMF with 1-butene and propene, butadiene with 1-butene, 2- cis -butene and propene, ethene/propene, and 1-butene/propene), the others being estimated by UNIFAC. The simulation shows that the relative volatilities of 1-butene and 2- cis -butene to butadiene increase at 1.6 and 1.2, respectively.…”

Replacing petrochemicals with products obtained from renewable raw materials is a top challenge today. The paper deals with the design and simulation of a sustainable process for manufacturing butadiene from bioethanol with a capacity of 91,000 t/year. The two-stage process employs a selective CuO/Cr 2 O 3 catalyst for ethanol dehydrogenation and recent yield-performant Ta 2 O 5 catalyst for butadiene synthesis. The paper develops original flowsheets suitable for industrial implementation based on comprehensive kinetic models that provide a realistic description of the actual chemistry. The development of a complex separation system makes use of a systematic task-oriented methodology. Efficient separation methods are applied according to the chemical nature and physical properties of species for removing numerous impurities generated in reactions. The overall butadiene mass yield and carbon yield are 0.495 kg butadiene/kg ethanol (vs the maximum value 0.587) and 0.837, respectively. The catalyst productivity is 0.253 kg butadiene/kg cat•h. Substantial energy savings are achieved by heat recovery around the chemical reactors and by applying heat pumping for ethanol recovery and recycling. The sustainability analysis reveals low material intensity (0.227 kg waste/kg butadiene), moderate energy intensity (0.562 kW h/kg electrical energy and 15.8 MJ/kg thermal utilities), and low impact on the environment. The economic analysis pinpoints the possibility of achieving butadiene prices competitive with petrochemical products if the process is integrated in a biorefinery.

“…Before designing pilot‐scale processes, it is highly recommended to test the efficiency of the fuel by using softwares including different simulators that can make accurate predictions 15. Aspen Plus® is a powerful simulation software used to predict process performance with high accuracy 16, 17. For gasification, kinetic models are not effective due to their limited and complex nature.…”

Thermal Performance Analysis of Ionic Liquid‐Pretreated Spent Coffee Ground Using Aspen Plus®

Thermal analysis and gasification study of spent coffee ground (SCG) pretreated with ionic liquids (ILs) is presented. Four ILs, namely, 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]), 1-ethyl-3-methylimidazolium chloride ([Emim][Cl]), tributylmethylammonium chloride ([N 1444 ][Cl]), and trihexyltetradecylphosphonium chloride ([P 66614 ][Cl]), were investigated. The pretreatment was followed by thermogravimetric analysis. The syngas composition was computed using an equilibrium-based steam-O 2 gasification model developed in Aspen Plus by varying gasifier temperature and steam/biomass ratio. All ILs reduced the ash content, enhanced the volatility as well as the higher heating value of SCG. IL pretreatment also decreased CO 2 and CH 4 contents showing environmental benefits of using ILs.
