Cumene
Overview
Advantages
The CDCumene® process, marketed by ABB, produces ultra high purity cumene using a proprietary zeolite catalyst that is non-corrosive and environmentally friendly. The CDCumene technology is one of a family of process technologies developed
and commercialized by Catalytic Distillation Technologies (CDTECH®) for license to the petroleum refining and petrochemical industries. CDTECH is a partnership between ABB Lummus Global and Chemical Research and Licensing.
Process Features
Client Benefits
Catalytic distillation structures provide efficient vapor liquid contacting, and combine reaction and fractionation in a single unit operation
High selectivity and lowered by-product formation high product purity without drag benzene high product quality (ultra low bromine index) without clay treatment high product yield reduced plot area ■
■
■
Proprietary zeolite catalyst
■
Meets evolving environmental requirements continuous operation transalkylation capability maximizes yield eliminates corrosive acidic effluents and associated disposal problems lower maintenance costs ■
■
■
■
Controlled low and constant alkylation temperature
Extends reactor run lengths (over one year without regeneration) sustains high conversion and selectivity
Simple, low pressure operation
Decreases capital investment improves safety and operability applicable to conversion of existing cumene plants
■
■
■
Improved heat integration and heat recovery
Reduces utilities and operating costs recovers all waste heat and heat of reaction ■
Adaptable to processing chemical and refinery grade propylene feedstocks
