properly treated in activated sludge STPs (Sewage Treatment Plant). LAS was highly removed leading to an effluent concentration in the 0.008-0.27 mg/l range. • LAS concentration was further decreased by dilution in the receiving waters where it could be found in the <0.002-0.047 mg/l concentration range. LAS degrades rapidly aerobically (half ...
This report analyses the economics of Linear Alkylbenzene Sulfonate (LAS) production from linear alkylbenzene (LAB) and sulfur in the United States, via a conventional sulfonation process. In this process, elemental sulfur is burned, yielding sulfur dioxide, which is then oxidated with dry air to produce sulfur trioxide, the sulfonating agent.

Sulfonation plants are scattered around the globe in production units with capacities varying from 3.000 to 50.000 tons/year, mainly of anionic surfactants. At least 800 sulfonation plants are estimated to be currently in operation around the World. However, about 20% of the global production (2.500.000 tons/year of sulfonated
The results obtained from the experiments can be upscaled to the production conditions of a chemical synthesis plant (Zhang et al., 2016). The toluene sulfonation process could also be downscaled to facilitate research and optimization ( Jiang et al., 2018 ; Sun et al., 2019 ).
The air/SO3 sulfonation process is the lowest SO3 cost of any sulfonation process and is extremely versatile, producing very high quality products. However, it is a continuous process best suited to large production volumes. In addition, it requires expensive precision equipment and highly trained operating personnel. Figure 8. Air / SO3

LAB plants based on UOP technology are based on four units. PACOL unit. In the in unit n-paraffins are dehydrogenated with a catalyzed reaction to produce mono-olefins. DEFINE unit. 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 quality.

Basic chemistry. Sulphonation is based on reaction between a sulphur trioxide stream diluted in air and an organic base. The reaction is carried out in a stainless steel multi-tube film reactor where the sulphur trioxide stream and the organic base are conveyed in co-current, for a reaction time necessary for a sulphuric group to react with the base and to form an additioned molecule.
sulfonation reactor is more than in a single-tube sulfonation reactor; however, the molar ratio of sulfur consumption and LAB is the same for both reactors. You can also notice that the film thickness in a multi-tube reactor is less than in a single-tube one. In this regard, we can assume that the diffusion of sulfur trioxide into the organic
