08:00 - 13:00
Site visit to Galveston Sulphur Terminal*

The Galveston Terminal, owned by Gulf Sulphur Services Ltd., LLLP (GSS) provides sulphur producers and consumers access to a wide range of sulphur handling services.  The terminal has the capability to receive and ship liquid sulphur by a number of transportation modes.  It has a permitted capacity of 3.5 million tons, with forming and blocking (vatting) capability.  The terminal can receive molten sulphur by tank truck, railcar, inland class barges, and ocean-going tankers.  The terminal can ship out sulphur in molten form by truck, inland class barges, and ocean-going tankers.  After forming, the formed or prilled sulphur is loaded onto bulk marine vessels for export via a traveling ship loader located on the main dock at the terminal.  The terminal started operation in 1969, is situated on 72 acres of land in the Port of Galveston, and is located on the Island of Galveston, Texas.

The site visit will depart and return to the Hilton Americas. The duration, including transfer time will be approximately 4.5 – 5 hours, departing at 08:00 and returning at approximately 12:30. The site tour will include a presentation of the Galveston Terminal and a bus tour of the facility. 

*Places are limited and will be allocated on a first come first served basis, so book early to avoid disappointment.  

09:00 - 12:30

Revolutionary method for temperature monitoring in Claus units
Due to the nature of Claus units, most successful temperature measurement systems require a nitrogen purge to increase the life of the Type S thermocouple. As the purge is a high maintenance item, the reading of the thermocouple can be affected when the purge rate is too high. This paper will discuss a solution to eliminate the high maintenance purge system, which is able to slow down the hydrogen migration and increase the life of the thermocouple without purging. Case studies will be shared.
