RECENT DEVELOPMENTS IN AUTOMATION AND ECONOMICAL TANK-CLEANING PROCEDURES

In the 1970s, no one would have mentioned tank cleaning machines as one of the most important pieces of equipment on a chemical tanker. This attitude has changed completely, owing to the expansion and greater sophistication of the chemical industry, new trade patterns, higher standards for product quality and purity, and increased concern for the environment. Demand for high-quality automated tank cleaning equipment can be expected to increase significantly. Recent developments at Tofte & Jorgensen A/S, Copenhagen, as manufacturer of such systems, are reviewed. They have focused upon spray nozzle design, the mechanics of liquid flow over tank inner surfaces, and the definition of optimal cleaning patterns. In his conclusion, discussing future perspectives, the author notes that the full exploitation of automated systems necessitates the deployment of fixed installations of tank cleaning machines that are computer operated via remotely-controlled valves and pumps. Further opportunities lie in the use of an expert system that continuously monitors key impurities in wash water to determine the optimal cleaning procedures, taking account of the next intended cargo and of local and adjacent cargo temperatures.
