Linear Alkyl-Benzene (LAB)
Linear Alkylbenzene Plants Technology
Desmet Ballestra offers plants based on the UOP
licensed Technology specificallydeveloped
for small capacity plants.
C10-C14 n-paraffins commercially available from producers。
Benzene commercially available from petrochemical producers.
High 2-phenyl (approx。 30 wt%) LAB widely used as surfactant intermediate
for LAS production。
Heavy Alkylate (HAB). Commercially valuable as a precursor of secondary
Hydrogen (H2). Commercially valuable as fuel.
Aromatics (from PEP Process). Commercially valuable as fuel.
LAB plants based on UOP technology are based on four units.
In the in unit n-paraffins are dehydrogenated with a catalyzed reaction to
The unit converts through a catalyst reaction di-olefins produced in the PACOL
unit into mono-olefins, thus improving the LAB production yield and the product
The PEP process removes aromatics from PACOL effluent stream, thus increasing
the DETAL catalyst life, improving the LAB product quality and reducing the
Heavy Alkylate production.
The DETAL process is a state of the art process for the manufacture of
detergent-grade Alkylate. It uses a solid heterogeneous catalyst to produce
Linear Alkylbenzene by the direct alkylation of benzene and mono-olefins. The
solid catalyst replaces the traditional liquid acid (HF acid or aluminum
chloride), with great advantages in terms of capital investment, potential
environmental impact and LAB product quality.
UOP LAB Technology has
several advantages compared to standard alkylation processes:
Pacol Unit does not require chlorine as raw material, resulting in an
system and allowing the use of conventional materials and reducing the
Potentially hazardous raw materials or by?products
are not used making the process also safer and simpler to operate.
Very selective in the production of mono?olefins,
granting a LAB product with less undesirable alkylindanes and alkyltetralins
and optimizing LAB product sulphonation performance。
High selectivity results in a higher yield of detergent alkylate product and
reduced feedstock costs。
Exceptional LAB product quality with better solubility for liquid detergents
and very low content of tetralins and indans.
Eliminates HF Handling
Lower capital cost.
Lower maintenance costs.
Very low waste disposal from the Plant.
