Executive Summary.
Aerosol hairspray cans are a cosmetic product used by 86% of women in the United States.(3) The consumer demand for hair products has stayed relatively steady since the invention of hairspray. Industrial suppliers can increase their net profit of aerosol hairspray production by analyzing and possibly optimizing their manufacturing process, mores specifically, the production of the most widely used aerosol propellant, dimethyl ether (DME). The optimization of a thermally coupled DME reactor (OTCDR) proves to be economical, energy sufficient, and increase the net profit of the industrial plant. It is in the best interest of industrial aerosol hairspray manufacturers to consider multiple alternative production

Hydrofluorcarbons (HFC’s) are a new class of recently developed propellants, they share many of the same properties as CFC’s but are less polluting. Several popular HFC’s include 1,1-difluoroethane and 1,1,1,2,-tetrafluoromethane. These propellants are relatively expensive but formulate fast drying. Currently the most commonly used propellant is dimethyl ether (DME).

DME has been receiving a growing attention all over the world in recent years, the study on the synthesis of DME is the process of most interest in regards to the production of hairspray. The production of hairspray is shown in Figure 1. Several methods of dimethyl ether are discussed. Optimization of a DME production process is discussed and analyzed. The process of DME production is discussed because of the promising energy consumption and economical value.

Dimethyl Ether
Dimethyl Ether is the most widely used propellant in aerosol cans in the United States (85%). Based on DuPont knowledge, national production of DME is 15 to 20 million kilograms in the United States. This production is distributed across the following primary uses: industrial feedstock for the product of other chemical substances (31%), hairsprays (48%), spray paints (6%), insect repellents/insecticides (6%), adhesives (5%), household cleaners (1%), dusters (1%), tire inflators
