Texas Tower / VCFE tubes cleaned with only 2m head room and top header in place.
A Texas Tower / Vertical Combined Feed Exchanger (VCFE) at a refinery on a Caribbean island was suffering badly from blockages and constrictions in the tubes. Texas Towers (VCFE’s) are vital as they cool down the platforming product against cold feed. Such heat exchanger has a very high heat duty. Loss of heat duty of only 10%, due to fouling in the tubes means a financial loss of 1.5 million USD every year. Fouling can lead to blocked tubes and this will eventually limit the design throughput. Such flow limitations lead to performance loss and that is big money loss.
Tube Tech mobilised to the Caribbean and successfully cleaned the exchanger, even though details of restricted top access were somewhat lost in translation. However, by modifying its automated technology, Tube Tech continued work from below and successfully pressure jetted the tubes.
