There are many units in the hydrocarbon industry that accumulate heavy deposits or sludge throughout production. During a turnaround these units can be extremely difficult to clean due to buildup of polymers, asphalts, heavy lube oils, and residues. Entry Safe Decon works with each customer to plan the best solution for entering the tower or vessel as safely and quickly as possible. One of the typical delays in a turnaround is cleaning the tower bottoms before treating the actual tower itself. Our technical team works with operations to determine what type of deposits will be difficult to fluidise, then advises on a chemical additive to add into a normal oil wash procedure during the turnaround. An oil wash enhancement can be utilised on the whole bottom circuit, including tower bottoms, exchangers, heaters, filters, and process lines.
