YOUR CHALLENGES In chemical, pharmaceu�cal and many more industrial se�ngs process safety is of cri�cal importance. Thermal risks must be assessed in normal and runaway process condi�ons to avoid costly down�me and damaging incidents to health, the environment and corporate reputa�ons. The Process Safety laboratory is fundamental to any chemical facility. Whether synthesising small or large amounts of material each process step and compound needs assessing for thermal stability. To avoid thermal hazards the en�re process from lab, to pilot, to plant, needs safe scale-up support with...

CUSTOMER TESTIMONIAL “If I was setting up a new process safety laboratory, I would start with a CALVET Calorimeter because even if I couldn’t solve each process safety problem, it can be used for both synthesis reactions (mixing cell) and decomposition reactions, by offering an appreciable advantage, namely pressure measurement. I would start with a CALVET even if it meant supplementing it later on.” Professor Stoessel - TÜV SÜD Process Safety Basel, Switzerland THE KEP TECHNOLOGIES ADVANTAGE KEP Technologies is radically step-changing it’s coverage of the process safety market by offering...

APPLICATION SCREENING DSC : ANALYSIS OF PROPERGOL INTRODUCTION The thermal decomposi�on of Propergol was studied in a �ghtly closed high pressure crucible and in an open crucible with milligram-scale samples. It was observed that if the pressure rises during decomposi�on (closed crucibles), both total heat and reac�on schemes are different. However, three peaks remain at similar posi�ons and shape (cf. arrows), which was confirmed by built-in deconvolu�on module of Calisto data treatment so�ware. The flexibility of Setline DSC gives fast insight into the behavior of chemicals under varying...

APPLICATION DECOMPOSITION OF DTBP BY RAPID SCREENING CALORIMETRY INTRODUCTION Di-Ter Butyl Peroxide (DTBP) is an unstable chemical used in the polymer industry to ini�ate polymeriza�on reac�ons. As large quan��es of such a product need to be stored at the plant, it is necessary to assess the risks with the thermal decomposi�on of this chemical. DTBP is also a typical compound used to assess the performance of Accelera�ng Rate Calorimeters and Rapid Screening Calorimeters. EXPERIMENT The temperature and pressure increase data obtained are very repeatable. RESULTS AND CONCLUSION 5 g samples...

APPLICATIONS ANALYSIS OF DIETHYL SULFATE INTRODUCTION The thermal decomposi�on of diethyl sulfate was studied in a �ghtly closed high pressure cell equipped with a pressure measurement system. EXPERIMENT The experiment was run at a scanning rate of 0.5°C/min. RESULTS AND CONCLUSION It was observed that the biggest contribu�on to the pressure increase was due to a first decomposi�on at about 175°C. The second decomposi�on peak is probably consuming part of the gas produced at the first stage. More informa�on can be extracted from this signal like pressure release rate, condensable / non...

APPLICATION DECOMPOSITION OF DTBP USING ACCELERATED RATE CALORIMETRY INTRODUCTION Peroxides, including Di-Ter Butyl Peroxide (DTBP), are typically unstable chemicals that require careful safety studies before being involved in industrial processes. EXPERIMENT The following were heated in 8 mL �tanium cells using the Heat-Wait-Search mode: • 5 g samples of the same 15 wt% DTBP solu�on in toluene • One 5 g sample of a 40 w% DTBP solu�on in toluene The Heat-Wait Search parameters were: • • • • • Start temperature: 97 °C Temperature steps: 5°C Soak Time: 30 min, wait �me: 30 min, search �me: 15...
