I was looking for sustainable solution for chemical engineering problems and i found this document.I request the answer that what kind of distillation tower or cooling system is described in attached report . If any one can include picture of such tower then its better to understand.
A. Design and use of stationary elevated pipes attached to distillation towers in the manner of a ship’s sail for cooling product with natural gulf winds rather than water.
-- The cooling fins were added to the plant for two reasons. Primarily, the original cooling tower was partially destroyed by a tornado. Putting up the sails was a more price sensitive alternative to replacing the tower. Secondarily, Keeshan and Bost routinely experienced power outages. Sails provided a reliable source of cooling when water cooling was limitedly effective on backup generators. At any one time, Keeshan and Bost has a need for cooling boiling liquid that is held in a container about the equivalent volume of a typical rail tanker. When power isshut down liquid will continue to boil even if the boiler is off. Fin tubes present a novel and efficient way to handle this problem. Taking advantage of the Texas Gulf Coast breezes, the fins are mounted 12-15 feet off the ground and drain via gravity, effectively providing condensers for separating hydrocarbons and alcohols from other parts of the process. These fins work very well for condensing liquids, which is the main energy demand in the system (this energy requirement is called Heat of Vaporization).

Here is link to a description of typical distillation towers"

The article you sighted appears to recommend using the wind to cool the overhead. This type of system would required a backup cooling system if they intend to operate the column (or shut it down safely) when the wind isn't blowing.
Thank you for your answer Sir but can you please help me to understand that what is meant by "sail - cooling pipes" ? Rick Manner
Thank you again.
Kaumil Panchal Cooling pipes often have "fins" on them to help cool them more quickly. I believe "sail-cooling" pipes have cooling fin that look like sail on a ship
This is a different type of chilled sail cooling, Probably not hat you are looking for
