Molsieve Economiser
Classificatie
Gas/Gascooler, Shell & Tube, fixed tubesheets, removable bonnet header, 2 pieces stacked in series
Kenmerken
A molecular unit requires a gas / gas economiser to recover heat. The pressures of the gas are high (85 barg) and there is an overlap in temperatures.
The economiser works by flowing gas on both sides and thus exchanging heat. In this case designed as a fixed tubesheet heat exchanger with pure counter flow where 2 hulls are stacked in series on top of each other. In this way, the overlap in temperatures is handled as efficiently as possible in a compact design.
Duplex has been chosen for the wet gas on the pipe side
It concerns a Shell & Tube heat exchanger. A one-pass shell with fixed tubesheets and removable bonnet headers. 2 shells stacked in series. TEMA type 2 x BEM 273/7000 made of C-steel with Duplex tubes and tube plates. Designed and built according to PED cat IV / Mod G + ASME VIII div.1, TEMA R and API 660
