Q & A > Question Details
My company aims at further processing the atm. distillation residue (Mazot); and a hydrocracker unit has been chosen for this task. We need to estimate the cost of the unit and its facilities like the vacuum tower and the vis-breaker. How would you suggest we get a rough initial estimate of the costs involved?

Hydrocracking for VGO is good but residue is not an easy task

Different company will give different estimates. My suggestion would be to go for a Once Through Hydrocracker (with lesser conversion) and you could use the bottom to feed FCC (you will consume some VDU bottom to maintain CCR) or use it for lube production.

You can check the CAPEX and OPEX of various processes quoted by licensors in the Processing Handbook published by Hydrocarbon Processing once every two years.

To obtain even a rough estimate of capital investments for a project of this kind and size a minimum of study is required. My experience is that from preliminary data of a process unit, errors of 50% or more can be made. In the cost study must be included the new facilities required such as utilities (steam generation, cooling tower, flare system, etc.) and off-sites (control room, infrastructure, storage, etc.), and additional processing units, as for example gas recovery and processing, sour water stripping, sulfur recovery, etc. Such investments are highly site specific and can be very different between refineries.

The company needs to engage the services of a 'process consulting firm' to sort out preliminary concept and order-of-magnitude cost estimate. There are a number a such consulting firms, including my own.
