Point Lisas, Trinidad

KBR (Houston, Texas) has built three 1,850 tonne/day plants in Point Lisas, Trinidad for Caribbean Nitrogen Co., and a fourth plant is under construction. The third plant has attained a production rate of up to 2,000 tonnes/day since it was started up in July, 2002. All these plants use KBR s KAAP technology215. 

Another key feature of this new process is the patented KBR Reforming Exchanger System (KRES), which eliminates the need for the directly fired primary reformer furnace (fig. 6.11). This reduces capital costs by 5-8%, and emissions of NO and CO2 by 70-75%. The first KAAP process was installed for the Ocelot Ammonia Company s (now Pacific Ammonia Inc.) retrofit of its plant in Kitimat, British Columbia, in 1992 and when the first two new KAAP plants (for Farmland Misschem and PCS Nitrogen) were completed at Point Lisas, Trinidad, in July 1998, they became the world s largest ammonia facilities (each at 1,850 t/day) to date. ... 

Trinidad Caribbean Point Lisas 550 Under construction 1993... 

Under construction in Trinidad is another plant of 500,000 t/year in Point Lisas, which is adjacent to the site of the existing methanol plant and ammonia facility. This is the Caribbean Methanol Corp. project scheduled for completion in late 1993. 

An example of a two-pass/two-stage SWRO plant is the 110,000-m /day Point Lisas facihty in Trinidad. This plant produces high-quality desalinated seawater of TDS concentration of 85 mg/L or less, which is predominantly used for industrial applications. The first pass of the Point Lisas SWRO system consists of six two-stage RO units. Each of the first-stage RO trains uses SWRO membranes and is coupled with energy recovery devices. The second-stage trains of the first pass are equipped with brackish water RO elements.
