Show Environmental Impact of Oil System Substantially Reduced The Chevron Pipeline Company has recently completed com-pleted Phase I of its pipeline pipe-line system which stretches nearly eighty miles from the eastern Utah oilfields toSalt Lake City. This part of the construe- tion projoct includes three combined heating and pumping pump-ing plants located at strategic strat-egic points along the way. 65,000 barrels of crude oil are transported daily to . the Salt Lake City refineries through the new system. Half of the volume is Alta-mont Alta-mont crude, which contains an exceptionally high content of wax, and the other half is a mixture from numerous numer-ous wells in the eastern Utah area. In addition to the pressure increases provided by pumping pump-ing stations along the line, it is necessary to heat the crude to keep it from becoming be-coming too viscous to flow. The heating and pumping stations are located at Hanna, Woodland, and Kimball Kim-ball Junction. When the oil leaves the Hanna station, which is the eastern-most point, it has been heated to 170 degrees and is not allowed al-lowed to drop below 100 deg. before reaching the refinery in Salt Lake City. Also the crude oil leaves the Hanna station under 1620 pounds per sq. inch of pressure. pres-sure. As it enters the Woodland Wood-land station the pressure has dropped to 350 lbs.sq. in. and is boosted to 800 lbs. sq. in. It enters the Kimball station sta-tion at 100 lbs.sq. in. and leaves at 400 lbs.sq. in. for the final leg of its journey. jour-ney. The Chevron Pipeline Company is to be commended commend-ed for its consideration in reducing the environmental impact of the pipeline system as much as possible. Visible emission from heating plant stacks has been essentially eliminated through proper design, and station sites were chosen where they would be least visible by the public. Because of the capacity of the pipeline, approximately approx-imately three hundred truck trips daily on Highway 40 between Roosevelt and Salt Lake City have been eliminated. elim-inated. Trucking mileage will be further reduced when Phase. II of the pipeline, which is a system of feeder lines from the wells to Hanna, has been completed. |
