Traditionally, oil & gas is one of the most demanding markets. Our team at ROBOX is well aware of this and possesses the thermal and process expertise this industry expects. We supply end-users directly or go through EPC’s or engineering firms, but we always deliver in full accordance with customer specifications. That is our standard and the reason why ROBOX has been thriving in this industry for almost 30 years now.
Whether it’s cooling for mobile wellhead compressors, high pressure gas coolers for an FPSO, crude pre-heaters for a refinery or glycol regeneration coolers for gas treatment, the oil & gas industry worldwide has always been our largest branch. Their strict requirements on design, construction, documentation and quality formed the basis of our workflows and are now business-as-usual. Naturally, our thermal designs are guaranteed.
Success in this industry is only achieved through expertise on every subject. The specialists at ROBOX gladly support and advise you along the way. Our track-record is our business card.
The cooling is done by Shell & Tube type Gas Coolers, fed with cooling water. Normally there is no phase transition, but in the unlikely event that this does occur, there is an outlet sump in which condensate is collected. On the sump are connections installed for level control.
Due to the deep vacuum of the process in which these coolers are installed, there is a large volume flow. Pressure loss is critical for these systems because it partly determines the size of the pump. During operation, situations can occur in which condensation occurs, measures must be taken to make the heat exchanger suitable for this.
To keep pressure loss as small as possible (only 0.2 mbar), large nozzles and a no-tubes-in-window (NTIW) design have been used. This means that no tubes are placed in the window (space above the baffle), which increases the flow rate. Due to the possible presence of condensate (drops), an impingement plate (collision plate) was mounted a...
For a project our customer (operating in the vacuum industry) desired gas coolers. These are assembled in a vacuum system skid that is delivered as a whole. The gas coolers provide the necessary cooling for the process gas.
