Decrease tube metal temperature in vacuum heaters
Various options for reducing the TMT of a vacuum heater, such as changing the transfer line size and adding extra surface area in the radiation and convection sections, are examined here. The best option generally depends on the limitations under which the heater operates with regard to the process requirements and the downstream equipment limitations and flexibility.
HP Water Management: Best practices for RO operations
Widespread use of reverse osmosis (RO) technology in industrial applications began in the late 1980s, following the introduction of polyamide materials that had a significantly higher permeate flow an..
Alfa Laval wins order to supply heat exchangers at US petrochemical plant

Mitigate heat exchanger corrosion with better construction materials
Better materials can provide optimal equipment service life, reduce maintenance, mitigate contamination by corrosion products and minimize heat loss due to fouling.
Mitigate fouling in crude unit overhead—Part 3
CASE STUDYThe basis for this case study is shown in Fig. 18; it is a crude unit with overhead heat integration. This is a one-drum overhead system with heat integration and no water wash. In an attemp..
Mitigate fouling in crude unit overhead—Part 2
Up to 50% of the refinery’s entire corrosion expense may occur in the crude unit. The root causes of the fouling and corrosion issues are often linked to the basic unit configuration choices, as ..
Improve solvent recovery in wax production
