DESCRIPTION

The DIESTA tube is a bimetallic finned tube with an aluminum sleeve1fully covering the base carbon steel tube. The outside aluminum fins are embedded into the grooves of the aluminum sleeve(1). To optimize the air-and tubeside heat transfer performance enhancement structures are applied on both sides. The aluminum fins on the airside combine both a groove and a dimple structure(2).Airside mechanical qualification confirmed robustness towards fouling, cleaning as well as mechanical strength of the fins equally to standard extruded finned tubes. The tubeside has an internally helical fin structure (3) ensuring an increased of tube side heat transfer coefficient while controlling the pressure drop.DIESTA Tech-nology is a development by the cooperation of Wieland,TechnipFMC and Kelvion.

FAQ

Q1: What is DIESTA technology?

A1: DIESTA is an innovative finned tube technology designed specifically for air-cooled heat exchangers. It utilizes enhanced surfaces to improve plant efficiency and reduce construction costs while adhering to the robust design requirements of oil & gas industry standards, such as API 661.

Q2: What are the key applications of DIESTA finned tubes?

A2: DIESTA finned tubes are primarily used in LNG air-cooler fields, including MR compressor inter- and aftercoolers, refrigerant coolers (desuperheater, condenser, and subcooler). They are also applicable in ethylene quench-water air cooler fields (especially naphtha-based crackers), gas processing plants, gas compression stations, and refineries. They are suitable for both greenfield and revamp debottlenecking projects.

Q3: What are the benefits of using DIESTA finned tubes?

A3: Depending on the project objectives, benefits include:

CAPEX savings: Up to a 20% reduction in air-cooler field length, leading to savings in structures, piping, wiring, and foundation.

Increased Revenue: Substantial benefits depending on individual process conditions, with LNG air-cooler optimization leading to up to a 3% capacity increase.

Improved CO₂ footprint: System efficiency improvement through the reduction of compression work.
