Abstract

A new method for early detection of runaway reactions in closed vessels is proposed. The method is based on continuous monitoring of the gas phase composition using on-line mass spectrometry, and can be used in reactions yielding gaseous products. The method has been applied to the study of the decomposition of organic peroxides (dicumyl peroxide and di-tert-butyl peroxide) in a RSST unit, and found to be faster and more reliable than traditional methods based on monitoring the temperature of the liquid phase.

    However, temperature leads to an earlier detection. Marco et al. (1997) have also tested monitoring of the gas phase composition using mass spectrometry. The results found show earlier detection compared to methods based on temperature measurements.

    In the frame of the AWARD European Project, an early warning detection system (EWDS) was developed and successfully tested both in small-scale and pilot plant chemical reactors, as well as in an industrial chemical reactor under batch and semi batch conditions (Ampelli and Maschio, 2012). The methods for EWDS can be divided into three main categories depending upon the quantities being used: conventional limit check systems (Marco et al., 1997; Tufano, 1988), temperature derivatives (Hub and Jones, 1986; Strozzi et al., 1999), and model-based estimation techniques (Semenov., 1959; Thomas and Bowes, 1961; Varma et al., 1999). In particular, the criteria that does not require models (such as the Hub and Jones and the Strozzi and Zaldívar criteria) are the most suitable for the application in real industrial systems with, for example, the use of the online sensors making them capable to prevent the runaway reactions.
