LLDPE Production from Ethylene and 1-Hexene (Similar to MarTECH)
LLDPE Operating Costs & Plant Construction Costs
This report examines the costs related to Linear Low Density Polyethylene (LLDPE) production from polymer grade (PG) ethylene and 1-hexene in the United States, using a slurry process similar to Chevron Phillips MarTECH. In this technology, ethylene is polymerized in combination with 1-hexene in a slurry loop reactor.
The report provides a comprehensive study of LLDPE production and related LLDPE production cost, covering three key aspects: a complete description of the LLDPE production process examined; an in-depth analysis of the related LLDPE plant capital cost (Capex); and an evaluation of the respective LLDPE plant operating costs (Opex).
The LLDPE production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The LLDPE plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The LLDPE plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises four major sections: (1) Feed Preparation; (2) Polymerization; and (3) Separation; and (4) Finishing.
Feed Preparation. This area comprises a catalyst activation system (fluidized-bed activator) and fixed bed treaters for purification of ethylene monomer, 1-hexene and isobutane, used as diluent in the polymerization.
Polymerization. In a loop reactor, the monomers and the catalyst suspension are mixed and circulated - as the polymer particles precipitate, they do not dissolve in the slurry. Cooling water in reactor jacket removes reaction heat. The slurry is continuously discharged to a flash chamber, for removing residual monomers.
Separation. The flashed stream passes through a bag filter for polymer fines removal. The fines are sent to the purge column. In the purge column, the residual hydrocarbons are stripped from the polymer product with heated nitrogen. The separated gaseous hydrocarbon streams from flash chamber and purge column are sent to purification in order to recover monomers and diluent, reused in the process.
Finishing. The polymer powder from the purge column, additives and antiblocks are fed to a pelletizing system, where the mixture is melted, homogenized, and pelletized. The pellets are homogenized in blending silos and stored.
