In 2014, a specialized division was created within Katalizator JSC to provide engineering services for the Company specialty processes, with a primary focus on the isobutane dehydrogenation process in a fluidized bed.
Since 2014, the division has been strengthening and developing its competences. 16 Russian patent applications and 11 foreign applications have been submitted, 15 Russian patents obtained and 2 foreign patent approvals received.
Currently, we are ready to provide a wide range of R&D services, author’s supervision of above sophisticated process.
Competences of Katalizator JSC allow R&D to be performed at the highest level with the use of analytical equipment combined with engineering calculations, and presenting a complete picture of the sophisticated processes in the dehydrogenation unit. Today, we would like to offer the following services:
Investigation and measuring of catalyst physical and chemical characteristics
Measuring homogeneity parameters of fluidization for fresh catalysts and mixtures
Measuring the catalytic activity, also in the presence of impurities
Investigation of catalyst reduction and regeneration kinetics depending on the nature of the reducing agent
Investigation of the reducing agent’s nature impact on the physical and chemical characteristics and performance of the catalyst
Performing all the required engineering calculations of dehydrogenation units
The measurements of catalyst physical and chemical properties are performed to explain the dependence of the dehydrogenation unit process on above properties. The park of laboratory equipment has been updated within the framework of the project “Implementation of the CET Technology Initiative: Catalysts, Engineering & Technologies” to ensure high-precision measurements.
A designated cold-flow fluidization bed bench scale unit with the height of about 8 meters is used for evaluating such important parameter as fluidized bed characteristics, namely:
Initial velocity and fluidization density
The expansion ratio of a fluidized bed
Above values are dependent on the nature of a catalyst, especially when it comes to modeling the operation of catalyst mixture, and are essential for performing calculations.
Calculations and process modeling is generally comprised of the following:
Evaluation and modeling the catalyst distribution along the reactor and regenerator grids (based on the actual readings)
Optimization of the catalyst PSD
Open space optimization for the sectioning grids
Calculation of mass and heat balance for dehydrogenation unit
Performance evaluation for stripping and reduction zones
Performance evaluation and optimization for regenerator
Design and optimization of inner and external cyclones
Calculation and development of design basis for recovery boilers
Performance optimization for the catalyst transportation system
JSC Katalizator provides a full range of engineering services, namely:
Comprehensive process audit of the units
Study of composition and properties for applied feedstock and catalyst
Performing required basic process calculations
Development of a Feasibility Study for revamping or catalyst replacement
Development of a Basic Design for construction, revamping, and optimization of dehydrogenation units
Supervision of construction, revamping, optimization for dehydrogenation units
Supervision of startup operations and reaching guaranteed operational performance of the unit
On-line supervision throughout the unit operating time
Today, the competence of Katalizator JSC enables it to develop customized comprehensive production solutions ensuring dehydrogenation unit operation optimization and OPEX reduction.
