Refractories for Chemical & Petrochemical Applications
Refractories in chemical and petrochemical plants line coal water slurry and residue oil gasifiers, secondary reformers, carbon black reactors, hydrogen production furnaces, gas generators and cracking furnaces. The technical reference's gasifier schemes build the lining from a high chrome brick working face, a chrome corundum brick backing, an alumina bubble brick insulating layer, refractory castables and a ceramic fibre coating or felt against the shell.
Refractory Requirements — Chemical & Petrochemical
The petrochemical technical reference is organised around equipment, and its most useful pages are four lining schemes: the Texaco coal water slurry gasifier, the four-jets coal water slurry gasifier, the secondary reformer and the Texaco residue gasifier. Each scheme is a legend of named layers rather than a product list, and the four are deliberately different from one another.
The two coal water slurry schemes build outwards from a high chrome brick working face through chrome corundum brick, alumina bubble brick and refractory castables to a ceramic fiber coating, with the four-jets version adding a ceramic fiber felt. The residue gasifier scheme replaces the chrome working face with high purity corundum brick and inserts a light-weight insulating brick layer. The secondary reformer scheme is simpler again: refractory castables, corundum brick and refractory insulating castables.
The table below follows those legends and the application sentence printed on each product page. Service-life figures and plant counts that appear in the technical reference are excluded from this website and are not quoted. Where a layer is named only in general terms, the term is shown as it stands rather than resolved to a specific product.
Where Refractories Are Used
4 equipment and zones
Coal Water Slurry Gasifier
Texaco Coal Water Slurry Gasifier / 4 Jets Coal Water Slurry Gasifier
The technical reference gives two schemes. Both build the lining in layers from the process side outwards: high chrome brick, chrome corundum brick, alumina bubble brick, refractory castables and a ceramic fibre coating; the four-jets scheme adds a ceramic fibre felt.
Residue Oil Gasifier
Texaco Residue Gasifier
A different lining from the coal water slurry scheme: corundum brick at the working face, then alumina bubble brick, light-weight insulating brick, refractory castables and refractory fibre.
Secondary Reformer
Refractories Conformation Scheme for Secondary Reformer
The technical reference's simplest scheme, built from refractory castables, corundum brick and refractory insulating castables.
Reactors, Hydrogen Furnaces and Cracking Furnaces
The technical reference names the carbon black reactor, the hydrogen production furnace, the gas generator, the cracking furnace and the intermediate frequency reactor on its product pages.

Technical Considerations
- Lining varies by gasifier type
- The technical reference gives four separate conformation schemes. The coal water slurry gasifier and the residue oil gasifier do not share a working lining: the first is lined with high chrome brick, the second with high purity corundum brick. No single lining is presented as suitable for all chemical furnaces.
- Where high chrome brick is used
- The technical reference states that high chrome brick is used as the working lining of coal water slurry gasifiers, petroleum coke pressurized gasifiers and other melting devices where acid alkali slag corrosion is serious.
- Where high purity corundum brick is used
- The technical reference states that high purity corundum brick is used in gasifiers and gas generators in the petrochemical industry, carbon black reactors in the chemical industry and high-temperature furnace linings in the ceramic industry.
