Valves integrated production

During the same semester, students will typically take a materials course (Engineering Materials) in which they perform mechanical testing of various materials. Previously, the labs had been done in isolation of unrelated materials, now the course draws on the integrating product to develop material specifications and perform tests related to the specifications for the valve materials. 

For the designed plant with no heat integration, there are 38 control degrees of freedom in this process. These degrees of freedom represents the available manipulated variables in the process and can be characterised as follow four feed valves, direct reaction and oxy-reaction coolers valves, direct reaction and oxy-reaction product valves, oxy quench cooler valve, three decanter product valves, pyrolysis preheater and heater valves, pyrolysis product valve, pyrolysis quench cooler valve, HCl heater valve, eight valves for the heating and cooling systems of the four distillation columns, thirteen valves for the base, top and reflux streams of the four distillation columns.
