Optimized Thermal Design
Advanced coil geometry and burner configuration ensure uniform heat distribution, eliminating hotspots.
Process Technology · Esteem-Owned · Esteem-Licensed
We license Acetic Anhydride plants — with end-to-end performance guarantees.
For 15 years Esteem has redefined the boundaries of Acetic Acid cracking. We own the Ketene cracker IP, supply the basic engineering & process design package, deliver complete LSTK plants, and stand behind the plant from raw material to finished product. We are not an executor under someone else's license — we are the licensor.

The Esteem Ketene Advantage
Severe-service capability with wider engineering relevance
The Esteem Ketene Process™ represents 15 years of continuous evolution and proven performance. Conversion efficiencies exceeding 92% are paired with improved energy performance and longer campaigns between decoking cycles.
More importantly, Ketene capability acts as a technology halo. A company that can engineer this service is bringing unusual process and thermal depth to refinery heaters, reformers, and revamp work as well.

Complete LSTK Acetic Anhydride Plants
Raw material in. Finished product out. We guarantee both ends.
Esteem provides complete LSTK Acetic Anhydride plants built around our proprietary Ketene cracker. We own the basic engineering and process design package (PDP), execute the entire plant under one accountable scope, and underwrite the finished plant with end-to-end performance guarantees from feed quality to product purity.
This is what licensors do. It is what separates us from execution-only contractors and from licensors who don't build what they design.
End-to-End Guarantees
Performance contract spans raw material specification to finished Acetic Anhydride product quality.
IP-Backed Process
Esteem-owned Ketene cracker design — no licensor royalty stack on top of execution.
One Accountable Scope
Process, engineering, fabrication, erection, commissioning — single point of accountability.
15-Year Track Record
Continuous evolution of the Esteem Ketene Process™ since the early 2010s.
