In addition to detergency performance and feedstock economics, other factors related to the processing of these powder formulations must be considered, such as sulfonation/sulfation, crutcher slurry preparation, and spray drying. AS and AES are thermally and hydrolytically less stable than LAS. Care must be taken in spray drying to avoid decomposition and pluming problems. This may place a limitation on the levels of AS and AES in spray-dried laundry powders.

The unit labor cost with insurance, tax, social, and other personal expenses is expected at US 27/h and the interest rate of about 4%. The variable cost items for drying of the laundry detergent slurry calculated according to the presented method are summarized in Table 65.6. The predicted variable cost is about US 1,685,699 per annum and US 47.78/t of dried product. Then, the expected unit cost of drying of the laundry detergent in the year 2006 will most likely be...

Following are some formulation examples of I I laundry detergents as shown in Tables 10.33 through 10.36. Laundry detergents are available in powder, solid block, liquid, and liquid gel/slurry. 

Problem description Based on the previously calculated balance and one-parameter dryer sizing, the factored estimate for a cost of the laundry detergent formulating and drying in a spray dryer is to be done. The system will be located in Pennsylvania in the year 2006. The required capacity of the dryer is 4.9 t of the product per hour (production period 7,200 h/y 35,280 t of dry product per annum) of which the moisture content should be about 7% w/w. The feed moisture content is 32.5% w/w, the feed temperature is 80°C, and the price of raw materials in the slurry in the year 2003 was US 1.48/kg (dry weight).
