From the pages of this blog we have repeatedly covered the issue relating to \u00a0thermoregulation in chemical plants<\/strong><\/a>.<\/p>\n

Surely I repeat myself, but to pick up the discussion, basically during the production phases implying the use of reactors, there are different temperature steps<\/strong> to be respected, to obtain the chemical reactions, the decompositions or to make the enzymes work<\/strong> in the correct way, avoiding the degrading or destroying active principles<\/p>\n

\"TREG<\/a><\/p>\n

These steps provide stops, heating and cooling gradients, basically real and proper engineering of temperature and of thermal energy<\/strong>, that with the TREG integrated systems we are able to correctly manage.<\/p>\n

A very interesting job has entailed the design and construction of 12 units<\/strong> TREG HC<\/b><\/a>, that were installed in two different plants, having similar management features.<\/p>\n

The first is a refining and concentration plant where the thermoregulation stations control the temperature level within a range varying from +10\u00b0C to +135\u00b0C. The adjusting fluid is pressurised water<\/strong> that transits in two different heat plate exchangers<\/a> which, through servo-activated pneumatic valves, controlled by remote PLC by the customer, allow setting the different temperature levels and the heating and cooling gradients.<\/p>\n

The realisation is completed faired, the internal piping in stainless steel, with highly efficient heat exchangers and centrifugal circulation electric pumps, with mechanical seal for high temperature.<\/p>\n

\"TREG<\/a><\/p>\n

With regard to the fluid adjustment, globe pneumatic valves have been used with regulator\/positioner fitted directly on the servo-control on both steam and on water, while on the process fluid side, the by-pass valves are on-off. All complete with limit switches and feedback on position.<\/p>\n

All completed by a series of alarm and safety signals, managed by the on-off equipment.<\/p>\n

The expansion tanks sized by our technical department, is managed and installed directly on the customer’s plant, since they are significant volumes.<\/p>\n

\"TREG<\/a><\/p>\n

The second plant has required 5 thermoregulation units<\/b><\/a>, for as many pharmaceutical reactors, where the process is in many ways similar, also requiring a temperature step close to -30\u00b0C<\/strong>, requiring little thermal energy.<\/p>\n

We have solved this by implementing a braze-welded heat pate exchanger for cryogenic applications<\/a>, supplied with non-freeze solution at -35\u00b0C<\/b><\/em><\/a>.<\/p>\n

To avoid wasting energy the moment intervention on this section is required, we have provided a particular type of operation that allows avoiding energy losses on other thermoregulation steps.<\/p>\n

The constructive logic traces the same choices with the addition of a remote control via the web, managed by the customer’s head office, for the control of energy consumption.<\/p>\n
