Process Licensing
Esteem-owned process IP for Acetic Acid cracking to Acetic Anhydride. You build under our license — not a third party's.
Process Technology · Esteem-Licensed · Esteem-Built
Complete Acetic Anhydride plants. Licensed and built by the same company.
Esteem licenses and delivers complete LSTK Acetic Anhydride plants built around our proprietary Ketene cracker. One accountable scope from process design through plant performance — with end-to-end guarantees from Acetic Acid feedstock to finished Anhydride product quality.

The Package
Raw material in. Finished Anhydride out. Guaranteed at both ends.
An Acetic Anhydride project usually involves two different companies: a process licensor who owns the technology and charges royalty, and an EPC contractor who builds the plant. Esteem is both. We own the process, we own the engineering package, we own the fabrication shops, and we commission the plant. One signature, one accountability line.
That is what separates us from execution-only fabricators in the region — and it is why we are in the peer set with UOP, Lummus, Axens, and Topsoe rather than with Thermax or J&K.

Single Scope
Scope of Supply
Everything from the process license to plant handover
The LSTK Acetic Anhydride package from Esteem covers the full chain — process IP, engineering, equipment, fabrication, erection, commissioning, and performance run-in.
Basic Engineering & PDP
Complete Basic Engineering & Process Design Package — heat and mass balances, PFDs, P&IDs, equipment specifications, utility summaries.
Detail Engineering
Full multidiscipline detail engineering — process, thermal, mechanical, piping, structural, civil, electrical, instrumentation.
Equipment Supply
Ketene Furnace (the flagship cracker), recovery columns, reactors, heat exchangers, and auxiliaries — engineered and procured under one accountable scope.
Fabrication
Pressure equipment fabricated at our ASME U + S Stamp, IBR-certified shops at Baddi and Indrad, with in-house refractory, painting, and NDT.
Erection & Commissioning
Field construction, pre-commissioning, commissioning, and performance run-in — with Esteem engineers on site through restart.
End-to-End Performance Guarantees
We stand behind the plant from feed to product
Most licensors guarantee the reactor. Most EPC firms guarantee erection. Esteem guarantees the whole plant — because we own both sides of the stack.
| Stage | What We Guarantee |
|---|---|
| Feedstock | Plant designed and guaranteed for specified Acetic Acid feed quality and throughput. |
| Cracker Performance | 92%+ conversion efficiency on the Ketene Furnace. Extended run length between decoking cycles. |
| Plant Uptime | Availability targets built into the plant design and supported through commissioning. |
| Product Yield & Purity | Finished Acetic Anhydride yield and purity specification guaranteed at the battery limit. |
| Energy | -15% energy per ton of Acetic Anhydride versus standard cracking practice. |
Plant Economics
Lower CapEx because the licensor and the builder are the same company
When a chemicals operator procures an Acetic Anhydride plant in the traditional way, the cost stack includes a licensor margin, a licensor engineering margin, and an EPC contractor margin — and each party optimizes its own scope. Esteem collapses that stack.
No royalty stack
A conventional project pays a licensor for the process, then pays an EPC firm to build it. We are both — so you avoid the stacked margin.
India-cost engineering
Basic engineering, detail engineering, and project management delivered from our Noida HQ at India-based engineering rates.
Single accountable scope
One contract from process guarantee through plant performance run-in. No licensor-vs-EPC finger-pointing when numbers don't match predictions.
Shorter schedule
Process and execution teams work from the same model, in the same office. Design reviews collapse. Field changes are resolved faster.

Downstream Markets
Where Acetic Anhydride goes next
Acetic Anhydride is the reagent of choice for acetylation chemistry. Demand is driven by pharma, cellulose acetate, specialty chemicals, and the paper industry — a stable base load with growth tied to pharma capacity expansion.
Pharmaceutical manufacturing
Acetic Anhydride is the workhorse reagent of acetylation chemistry — aspirin, paracetamol intermediates, and a wide range of acetylated active pharmaceutical ingredients.
Cellulose acetate
Films, textile fiber, and cigarette filter tow — all derived from cellulose acetylated with Anhydride.
Specialty chemicals
Sorbic acid, alkyl ketene dimers, acetyl chloride, and other intermediates for downstream chemicals producers.
Paper industry
Alkyl Ketene Dimers (AKDs) for paper water resistance — a large and steady end market for Anhydride derivatives.
Engineering Behind The Plant
The same engineering depth that designs the cracker designs the plant
The Ketene Furnace — the plant's most severe-service unit — is designed in WinHeat®, our proprietary thermal rating engine under continuous development since the 1990s. CFD is used to verify tube-skin uniformity and eliminate hot spots. FEA confirms mechanical integrity under thermal cycling.
This is not third-party engineering wrapped around a licensed process. It is our own process, engineered in our own tools, by the same team that guarantees plant performance.
