Plastic Pyrolysis Plant Optimization

JOB TITLE
Freelance Chemical / Process Engineer – Plastic Pyrolysis Optimization
PROJECT DESCRIPTION
We operate a 7.5–8 TPD batch plastic pyrolysis plant processing LDPE, HDPE and PP.
We are looking for a freelance Chemical / Process Engineer to help optimize plant performance and reduce wax formation.
The plant is already operational. We need process optimization, not basic plant design.
OBJECTIVE OF CONSULTATION
• reduce wax formation percentage
• increase liquid oil yield
• increase diesel fraction (C12–C18 range)
• improve vapour cracking efficiency
• stabilize vapour temperature profile
• optimize condenser temperature staging
• improve consistency between batches
PLANT CONFIGURATION (SUMMARY)
• rotary batch pyrolysis reactor
• 7.5–8 ton plastic per batch
• feedstock: LDPE / HDPE / PP mixed plastic
• non-catalytic process
• multi-stage vapour residence path
• mini tar removal vessel
• vapour-liquid separator
• 4 stage vertical condensers
• 2 horizontal condensers
• final polishing condenser
• hydroseal system
