Distillation towers are the most common example. They have a phase separation process based on the different evaporation points of each component of a multi-component fluid such as crude oil and its derivatives. Heat is sent to the bottom of the tower. Vapor goes up through the tower and gets in contact with the descending liquid. A number of internal parts, such as plates and gaskets, enable the contact between the phases. The heavier components are concentrated in the liquid phase and eventually they turn into the bottom product of the tower. The vapor phase is constantly enriched in the lightest components that will make up the overhead product. It is possible to get intermediate products of the different contact stages. All the equipment manufactured within our shop floor is tailored-made. This means they are designed and built meeting the specific requirements from each customer and each installation. And therefore they can be built in different materials (special steel, stainless steel, other alloys), painted according to different schemes and/or thermally insulated. During the entire manufacturing process we comply with material tracking, and the design and construction are performed in accordance to ASME standards.
