👀 Read how Artelys Knitro is used to help researchers design reactors for methanol synthesis from renewable resources Methanol is an important compound widely used in the chemical industry. Today, it is largely produced using fossil-based resources. Synthesizing methanol from renewable energy poses the challenge of the varying availability of green hydrogen as a feed stream. Conventional processes are not designed to consider such fluctuations. The objective of this paper is to identify the optimal design of a multi-stage reactor for green methanol synthesis with inlet fluctuations. The authors model the reactor’s design parameters and operating conditions and propose an optimization problem to maximize the methanol yield, subject to a minimum carbon conversion rate. They solve the problem in the nominal steady-state and in a robust steady-state version, which is feasible for different inlet fluctuation values. However, through numerical simulations, they show that these models are not feasible when transient behavior is considered. They hence propose a dynamic programming model that allows the feed distribution and shell temperatures of the reactor to change over time, depending on the varying value of the inlet stream. Experiments show that this problem is feasible for fluctuating inlet conditions. All three optimization problems are continuous and nonlinear and require a discretization of the infinite dimensional problem to be solved. The authors exploit the power of Artelys Knitro with the multi-start option to solve all three of them.

👀 Read how Artelys Knitro helps economists assess the effects of CO2 auctioning for decreasing greenhouse gas (GHG) emissions in an economically efficient manner. One of the main strategies to reduce GHG emissions is to trade emission allowances or permits on organised markets. Indeed, pricing CO2 encourages investments in low-carbon technologies. The design of emission trading markets is crucial to ensure their efficiency and fairness. The authors examine the interaction between electricity generators within an oligopolistic market. They use a game-theoretical model that considers the interplay between the electricity market and the emissions market in a two-stage stochastic framework. Electricity quantities and emissions allowances are contracted in advance and committed at the futures price in a futures electricity market (first stage). Then the actual delivery of electricity and allowances occurs in a spot market (second stage). These market interactions are modelled as a game-theoretical equilibrium with both risk neutral and risk averse generators. This problem is modelled as an optimisation programme that maximises a weighted average of expected profits and the conditional value at risk thereof (CVaR), resulting in a continuous quadratically constrained quadratic problem (QCQP). The authors use Artelys Knitro to solve this problem and to derive multiple conclusions, performing sensitivity analyses on renewable energy penetration and carbon prices for generators with different attitudes towards risk. The performance of the solver enables to consider hundreds of scenarios with varying electricity and emission allowance prices, generation costs, and level of nondispatchable renewable energy generation.

📢 Artelys est heureux de collaborer une nouvelle fois avec Grenoble-Alpes Métropole pour la révision de son schéma directeur des énergies, après avoir réalisé la première version en 2017 ! L’objectif de l’étude est d’identifier le meilleur mix énergétique pour atteindre la neutralité carbone d’ici 2050 en visant un usage optimal des réseaux énergétiques métropolitains. Grenoble Alpes Métropole s'inscrit ainsi parmi les métropoles précurseurs en étudiant finement l'impact des scénarios de transition énergétique sur les réseaux de distribution d'électricité, de gaz et de chaleur afin d'anticiper au mieux l'évolution de son système énergétique. 💡 Pour y parvenir, Artelys s'appuiera sur ses compétences éprouvées en planification énergétique - et son logiciel dédié Artelys Crystal City - ainsi que sur sa large expertise en modélisation et simulation des réseaux de distribution d'énergie. 💪 Dans ce projet, nous sommes ravis de travailler une fois encore avec AEC qui apporte son expertise économique, notamment sur l'avenir des réseaux de distribution de gaz.

Nonlinear programming is a fundamental paradigm to solve optimization problems. We just published two additional notebooks on our Github account: https://lnkd.in/d-aaHbEi to illustrate what can be done with nonlinear programming. If you're interested to see what nonlinear programming can be used for, do not hesitate to check them out. The first notebook is about the well-know k-means clustering problem and its variants. 👉https://lnkd.in/dwWNCJPr The second notebook shows a facility layout problem. 👉https://lnkd.in/dYfRWXfU You can read the notebooks online or request a trial licence of Artelys Knitro to run them on your own machine.
