Chemical Engineering Consulting forms the bedrock of our practice. Dr. Yadav brings end-to-end expertise in chemical process design, equipment sizing, heat and mass balance, and engineering analysis for complex industrial systems. Whether you are designing a new process from scratch, troubleshooting an existing plant, or evaluating capital expenditure for process scale-up, our consulting approach is anchored in rigorous engineering fundamentals and real-world practicality.
We work across both continuous and batch chemical processes, covering reaction engineering, separation systems, heat integration, utility optimization, and process control strategies. Our deliverables are designed to be immediately actionable by your engineering teams — providing not just recommendations but detailed technical documentation, process flow diagrams, simulation models, and implementation roadmaps that empower your organization to move forward with confidence. Clients range from mid-scale chemical manufacturers to EPC companies developing large greenfield facilities.
Catalysis is at the heart of modern chemical industry — from petroleum refining and fertilizer production to pharmaceutical synthesis and green hydrogen generation. Dr. Yadav's doctoral research and subsequent professional work in this field place him among the leading catalysis consultants in India. We offer comprehensive catalyst selection, design, characterization guidance, performance benchmarking, and deactivation analysis for both fixed-bed and fluidized-bed industrial reactor systems.
Our catalysis consulting engagements span the full catalyst lifecycle — from initial material selection and synthesis protocols through to performance testing, reaction kinetics modeling, and long-term deactivation management. We integrate reaction engineering principles with practical operational insights, providing clients with a clear pathway from catalyst laboratory results to reliable industrial-scale performance. Whether you are developing a new catalytic process or optimizing an existing reactor, Dr. Yadav delivers evidence-based solutions grounded in cutting-edge catalytic science.
Green hydrogen is rapidly emerging as a cornerstone of global energy transition strategies, and India's National Green Hydrogen Mission is creating unprecedented demand for technically credible consulting expertise. Dr. Yadav is one of India's leading green hydrogen consultants, providing comprehensive advisory services covering electrolysis technology selection, system integration, hydrogen storage and compression, and techno-economic assessment. We support project developers, industrial hydrogen consumers, and government programs at every stage of the hydrogen value chain.
Our green hydrogen consulting draws on deep expertise in electrochemical engineering, renewable energy systems, chemical process integration, and economic modelling. We conduct rigorous levelized cost of hydrogen (LCOH) analysis, technology benchmarking across alkaline, PEM, and SOEC electrolyzers, and project-specific feasibility assessments that give investors and developers the technical confidence required for large capital commitments. From concept to commissioning, we are your trusted green hydrogen partner.
The integration of renewable energy sources into chemical and industrial processes represents one of the most significant engineering challenges — and opportunities — of our time. Dr. Yadav provides specialized consulting on solar, wind, and hybrid energy system integration with chemical process plants, refineries, fertilizer facilities, and industrial utilities. Our approach combines chemical process engineering with energy systems design to create practical, cost-effective, and technically sound renewable integration pathways.
We conduct detailed energy audits, identify decarbonization opportunities, model renewable energy supply-demand profiles for industrial operations, and provide implementation-ready integration plans. Our renewable energy advisory services are fully integrated with our sustainability consulting, ensuring that every energy transition decision is evaluated against both technical performance and broader environmental impact metrics. The result is a comprehensive decarbonization strategy that makes business sense and engineering sense simultaneously.
Sustainability is no longer optional for industrial enterprises — it is a regulatory, financial, and competitive imperative. Dr. Yadav's sustainability consulting practice integrates deep chemical engineering knowledge with lifecycle thinking, carbon accounting, and ESG strategy to help industrial clients build credible, defensible, and implementable sustainability programs. We work across the full sustainability spectrum — from operational carbon footprint reduction to supply chain decarbonization and regulatory compliance.
Our Lifecycle Assessment (LCA) services quantify the environmental impact of products and processes from cradle to grave, enabling informed decision-making on technology choice, raw material selection, and process design. Our sustainability roadmaps are built with engineering precision — identifying specific, measurable interventions that reduce emissions, waste, and resource consumption while maintaining or improving commercial performance. Whether preparing for ESG disclosure, responding to investor pressure, or pursuing green certifications, we provide the technical backbone your sustainability commitments require.
Most chemical plants operate below their theoretical performance ceiling. Process optimization consulting by Dr. Yadav systematically identifies and eliminates the technical, operational, and design inefficiencies that limit throughput, yield, energy efficiency, and overall plant profitability. We combine detailed process data analysis, simulation modelling, and on-site engineering assessment to generate a comprehensive picture of your plant's optimization potential.
Our optimization engagements begin with a thorough process performance audit — benchmarking current operation against theoretical targets and identifying gaps. We then develop prioritized improvement recommendations ranked by technical feasibility, implementation cost, and financial return. Whether it's reaction condition optimization, heat exchanger network retrofit, column operation improvement, or utility system redesign — we provide detailed engineering support through implementation, ensuring that identified savings are actually realized on the plant floor.
Sound investment decisions require sound feasibility analysis. Dr. Yadav prepares comprehensive techno-economic feasibility studies for greenfield and brownfield chemical engineering projects — providing investors, project developers, banks, and government agencies with the rigorous technical and economic analysis needed to make informed capital allocation decisions. Our feasibility studies combine process engineering depth with financial modelling sophistication to present a complete project picture.
Every feasibility study we produce includes a detailed technology assessment, conceptual process design, capital and operating cost estimation, market and feedstock analysis, sensitivity analysis on key assumptions, and a clear go/no-go recommendation with supporting evidence. Our reports are structured to meet lender requirements, satisfy investor due diligence, and guide engineering contractors through basic and detailed design phases. We have prepared feasibility studies for chemical plants, green hydrogen facilities, renewable energy projects, and industrial decarbonization initiatives across India.
Research and development in chemical engineering, catalysis, and energy systems requires both deep scientific expertise and practical engineering judgment — a combination that is rare and highly valuable. Dr. Yadav's R&D support services assist research institutions, universities, startups, and industry innovation teams in designing, executing, and scaling their research programs more effectively. With an IIT doctoral background and extensive post-doctoral and consulting experience, Dr. Yadav brings world-class scientific rigor to every R&D engagement.
