<br />Coal Capsule Pipeline?
<br />By W,R, Grace & Co.
<br />
<br />Concept: A pipeline unique to the
<br />Colorado River drainage area
<br />for transporting coal contained
<br />in disposable plastic capsules
<br />and thus completely separated
<br />from the saline water medium
<br />used to obtain neutral buoyancy
<br />of the coal container.
<br />
<br />The Salinity Control Forum has grappled for
<br />many years with the problems of eXGfl~<;sive
<br />total dissolved solids in the Colorado River.
<br />and we in the coal industry have been
<br />struggling to remain competitive in the face
<br />of rapidly escalating rail rates, I would like to
<br />offer you an ide.a that we at WR Grace & Co,
<br />are working on that could partially solve both
<br />of these problems,
<br />An unusual opportunity exists in the
<br />Colorado River basin fortranspof1ing coal via
<br />pipeline to the Pacific Coast and in the
<br />process disposing of some of the Colorado
<br />
<br />River's total dissolved solids problem, The
<br />project envisions the cooperation of Federal.
<br />State, local. public. and industrial entities to
<br />remove about 10 percent of the salts
<br />currently entering the Colorado River and to
<br />pass this saline water through a pipeline to
<br />the Pacific Ocean, We feel the capital
<br />investment for the pipeline could be obtained
<br />from private sources based on Federal
<br />paymenls for removal of salls from the
<br />Colorado River and transportation fees for
<br />encapsulated coal to market.
<br />A 36-inch diameter pipeline would be
<br />constructed from a point near Axial,
<br />Colorado. to a point yet to be ascertained on
<br />the California Pacific Coast. a distance of
<br />about 1.200 plus miles, Coal mined in
<br />Colorado and Utah would feed the pipeline
<br />with up to 20 million tons per year, Fresh
<br />water owned by WR. Grace & Co" about
<br />12.000 acre Ie-et per year, could be used to
<br />transport pal1 of the coal from Axial to a point
<br />near Rifle. Colorado. where it would be
<br />exchanged for water conlaining up to 14.000
<br />
<br />milligrams per Iiler of total dissolved solids,
<br />from Ihe Glenwood/Dotsero Springs for
<br />transport to the Pacific Ocean.
<br />The Bureau of Reclamation has been
<br />charged by Federal law with Ihe
<br />responsibility to reduce salt conlent of the
<br />Colorado River. as measured at Imperial
<br />Dam in Arizona. to the 1972 level. This calls
<br />for 2.8 million tons of salt removal from the
<br />drainage system of the Colorado River by
<br />around the year 2000, The proposed saline
<br />waler/co'sl capsule pipeline projecl would
<br />remove an estimated 250.000 tons of salt per
<br />year of the required amount.
<br />This pipeline would differ dramatically from
<br />a coal slurry pipeline. The coal would be
<br />crushed. cleaned, and dried al the mine, It
<br />would then be placed in a plastic capsule
<br />("baggie"), The capsules containing the coal
<br />would have a specific gravity equal 10 Ihe
<br />saline water which would transport them to
<br />the Pacific,
<br />The process of transporting coal in plastic
<br />capsules was patented and has been
