The company offers integrated solutions for projects involving formaldehyde and phenol, two key building blocks in resin synthesis and specialty chemicals. For phenol production, the company can assist in evaluating cumene process technologies (cummene hydroperoxide cleavage to phenol and acetone), with catalyst optimization (molecular sieves for high selectivity > 92%) and energy integration (heat recovery from cumene oxidation). Formaldehyde production technologies (silver catalyst or iron-molybdenum catalyst processes) are offered with capacities ranging from 10 to 500 kt/year, producing formaldehyde solutions (37 - 55% concentration) with low methanol content (< 0.5%). The company’s expertise in handling both chemicals includes safety system design for storage and handling (explosion-proof design, vapor recovery systems), and process integration for resin production, such as continuous PF resin plants with automated dosing and mixing systems. Contact us for detailed process flow diagrams and hazard analysis for combined formaldehyde-phenol projects.

Intercontinental Operations but Local touch

Intercontinental Operations but Local touch

We incorporate international best standards and local contextualisation of issues in all the operations we manage within south east and west Asia regions. This distinct edge differentiates us and enables us assist our clients in solving problems that are not only useful but also applicable to their culture. Our teams append areas of practice for specific problems provided different regions have formaldehyde and phenol that is contacting different sagittal planes off the body.
