I am going to design a liquid ammonia pipeline of 10km with 1000MT per Hour flow. Client is suggesting 'DRY' and 'WET' concepts and I have to evaluate pros and cons of both options. "WET PIPELINE SYSTEM" defines constant flow of liquid ammonia through the line irrespective of loading or not. when there is no loading, liquid ammonia will be recirculated. "DRY PIPELINE SYSTEM" define lines to be consists of ammonia vapours when there is no shipping.
Expecting your valuable advices in this matter..
