Lummus Technology offers the innovative ModGrid® catalyst stripper to improve the performance and flexibility required to meet the demands of today’s marketplace. The ModGrid stripper is a novel hardware design commercially proven to increase unit profitability. The unique, patented configuration provides a cost-effective and reliable solution for all modes of operation. The modular construction allows for easy installation through existing manways.
- Baffles are assembled and built as modular grids
- Surface area is maximized for mass transfer between catalyst and steam
- Channeling, bypassing, back-mixing and dead spots are eliminated
- Catalyst takes a 360° turn as it flows down the stripper, improving radial mixing
Benefits
- Reduced dry gas and delta coke
- Reduced generator temperature—provides capability to increase feed rate and/or process heavier feeds
- Higher catalyst-to-oil ratio
- Increased conversion and yield of light products
- Reduced steam consumption
- Highly attractive return on investment—typically measured in weeks
