This disclosure relates generally to methods and systems for screening and design of corrosion inhibitors. Conventional techniques in the art for predicting the inhibition efficiency of the molecule are not so accurate, where the inhibition efficiency is one of the important parameter for screening and design of corrosion inhibitors. In the present disclosure, the IE prediction model is developed by training a multi-task network model using the molecular descriptors of different classes of the molecules, and also the experimental conditions of the molecule. Further, a unique screening technique is disclosed that screens the molecules using various parameters including the inhibition efficiency of the molecule, an energy gap of the molecule, a synergistic effect of the molecules and an interaction energy of the molecules. Further the present disclosure allows to design a new molecule by making changes to the molecules that suits based on the end applications.

Methods and systems for screening and design of corrosion inhibitors

This disclosure relates generally to method and system for designing the formulated products. Conventional techniques for designing the formulated products, meeting final functional properties, are limited. Further, understanding user requirements and active incorporation of the user requirements during design phase is quite challenging. The present disclosure herein provides method and system that solve the technical problem of extracting the functional requirement by establishing continuous conversation with the user. An optimal prediction function for each functional requirement is determined by using a plurality of prediction models. An optimization technique along with an objective function is employed to determine optimized solutions comprising list of ingredients, possible concentration level of each ingredient, the process parameters, and the operating parameters for obtaining the desired formulation based on the user requirement.

Method and system for designing formulated products

This disclosure relates generally to selective flocculation, and more particularly to portable test-device for performing selective flocculation experiments in continuous mode. The test-device includes a slurry inflow system, a flocculant tank, a static mixer, a control pumping system, and a thickener system. The static mixer is connected to the slurry inflow system and the flocculant tank, to receive and mix flocculant solution and slurry and cause formation of floc. The control pumping system connects the flocculant tank and the slurry inflow system to the static mixer to control the control parameters responsible for pumping the slurry and flocculant solution in the continuous mode in the static mixer. The thickener system comprises a thickener tank to receive treated slurry and the floc from the static mixer, separately collect tailings and the floc from the thickening tank. The components of the portable test-device are removably connected to each other.
