Pumps for hot slurry service may be configured in another manner, as shown below.
Because the line requires a large flexible loop, the amount of dead leg in the line for the non operating pump must be minimized. The plant layout designer should discuss this particular arrangement with the vessel engineer.
When the vessel data sheets are sent out for quotation, the split bottoms outlet connection is included in the basic design. Making this type of decision too late can be very costly and may delay delivery of the vessel.
The designer should not just take information as is but should look for ways- to improve the overall design or lower the cost of the plant in all disciplines.
