REACTIVE CHEMICALS COMMITTEE REVIEW - DECEMBER 8, 1987
PROJECT: High Density Polyethylene Incremental Expansion Capital Authorization
PROJECTS REPS: Gary Camp, Tim Holder, Dave Turner
COMMITTEE PRESENT: Pennington, Cochran, Bullman, Steward (Nevill), Mitchell, Christensen
CONSIDERATIONS:
The Train I upgrade represents no new chemistry and is the same technology as existing Trains II and III.
The Train III Degassing Modification duplicates the existing Train IV technology.
The Committee identified no Reactive Chemicals concerns and therefore supports this authorization.

HIGH DENSITY POLYETHYLENE INCREMENTAL EXPANSION
Authorization of $3,650,000 is requested to provide materials and labor to (1) recommission the Train I reactor system and (2) install degassing capability on Train III reactor system at the High Density Polyethylene (HDPE) production plant located in the Louisiana Division. The recommissioning of the Train 7 system will provide an additional 45 million pounds per year of HDPE resins for U.S. trade sales.
Recent recommendation from the Global Plastics Strategy Task
Force indicated that HDPE resins are critical to Dow's
future strategic growth in plastics.
The Polyethylene
Business Team in concert with the HDPE Product Management
Team has defined a strategy to become a major participant in
the HDPE market through licensing technology and building or
acquisition. This new position will provide us with the
ability to supply a broad range of higher molecular weight
products that are cost competitive. In support of this
strategy, it is necessary to participate more aggressively
in selected market segments where we currently have r sin
advantages versus the majority of polyethylene
manufacturers.
The current two train HDPE production plant is limited to
180 million pounds per year, of which, 45 million pounds is
utilized internally as a feedstock for
resins. The balance of production is sold
trade applications. This project would provide for the recommissioning of Train I, one of two smaller (45 million pounds per year) reaction trains that were rationalized in 1985, to supply feedstock to the TYRIN,TMx plant. This will then allow the entire production of the two existing trains to be dedicated to the trade market. Additionally, Train III will be modified to be able to produce truly bimodal resins through the addition of a degasser and appropriate other equipment.

The project package includes modifications to the existing
Train I instrumentation and solvent recovery systems, and
the installation of a stainless steel process hold tank.
Instrumentation which is currently pneumatic will be
replaced. The solvent recovery system will be modified to
match the latest technology on the two currently operating
trains, including the installation of a hydroclone system
and a vacuum recovery system to minimize solvent losses. To
improve temperature control in the process hold tank, a
major quality control parameter, the existing glass-lined
tank will be replaced with an existing stainless steel
vessel.
These changes will be incorporated with the
existing Train I equipment to provide a quick and proven
capacity increase.
Forty-five million pounds of ethylene per year will be
required for this expansion. One additional operator per
shift (total 'of 4) will be required.
No additional
supervisory personnel are required.
Support letters from the Polyethylene and Derivatives
Technology Center,
Polyethylene Business Manager,
Safety/Loss Prevention, Environmental Services, Plastics
Material Services, and Reactive Chemicals Committee are
attached.
A pre-manufacturing notice is not required for this project. All depreciation will be on Account 67. The projected RTO
date is nine months after authorization (projected 4th Qtr,
1988). The projected spending schedule is for the entire
$3,650,000 to be spent in 1988. Project manager for this project is Gary Camp.
