4-Parallel Slurry Fischer-Tropsch Testing Unit
A novel low-flow dosing system
4-Parallel Slurry Fischer-Tropsch Testing Unit
The task
Designing a unique, 4-parallel slurry Fischer-Tropsch testing system.
ILS was approached by one of its oldest clients to develop a unique, 4-parallel slurry Fischer-Tropsch testing system. This client is one of the worlds major Fischer-Tropsch wax manufacturers. ILS was chosen both for it’s excellent track record with this client as well as because of the large number of both fixed-bed and slurry Fischer Tropsch units that ILS had already made. Issues around reactor hydrodynamics and heat removal were well known to us at the time.
The ILS solution
ILS designed a novel low-flow dosing system for feeding mg/min quantitites of water and alpha-olefins to the reactors for kinetic testing.
The ability to do sulphur poisoning studies was also included.
Inclusion of carbonyl capture reactors to the feed section insured that no nickel or iron carbonyls formed in the CO storage bottles would deposit on the catalyst surface potentially falsifying data. The unique combined ILS liquid-level control and slurries separaiton system insures that the wax level is exactly regulated and that the outlet lines to not block even when operating with very high solids contents of extremely fine FT-Slurries. Inclusion of on-line gas-phase GC-analytics as well as fully automated wax and water/alcohol collection mean that only a limited staff is required to operate the unit.
The result
The unit was successfully delivered to our client and it has been in operation for 8 years now and continues to produce valuable data for this client.
This represents yet another of the many GTL systems that ILS has had the pleasure of making over the last 14 years.
