Alfa Laval Packinox for xylene isomerization

Product catalog summary

Introduction
The document discusses the Alfa Laval Packinox heat exchanger, specifically its application in xylene isomerization processes. It highlights the advantages of using Alfa Laval Packinox over traditional shell and tube (S&T) heat exchangers, particularly in terms of cost savings and operational efficiency.

Specifications and Applications
Alfa Laval Packinox heat exchangers have been used in xylene isomerization units since the mid-1990s, with over 35 units installed by 2000 in paraxylene production plants. These exchangers offer significant capital savings on installation, transport, foundation, and piping, as well as fuel economy in associated process equipment.

Case Study: New Unit
The document provides a case study comparing Alfa Laval Packinox with traditional shell and tube exchangers. Key specifications include:

Hot End Approach (HEA): 28°C for one shell, 50°C for two shells
Duty: 90 MW (307.1 MM Btu/h) for one shell, 83 MW (283.2 MM Btu/h) for two shells
Heat recovery: 7 MW (23.9 MM Btu/h)
Estimated dry weight: 128,000 kg for one shell, 220,000 kg for two shells

Cost Analysis
CAPEX

Estimated equipment cost: $2,800,000 for one shell, $2,600,000 for two shells
Estimated installation cost: $1,120,000 for one shell, $1,820,000 for two shells
Total installed cost: $3,920,000 for one shell, $4,420,000 for two shells
Total CAPEX savings: $850,000, including $500,000 on the heat exchanger and $350,000 on other equipment (heater, cooler)

OPEX

Energy savings per year: $3,150,000
Emissions savings per year: $560,000 (Nox, Sox, GHG)

Alfa Laval Packinox for xylene isomerization-1

Alfa Laval Packinox heat exchanger Mixed xylene Paraxylene Recycled hydrogen Standard combined feed/effluent heat exchanger Alfa Laval Packinox for xylene isomerization Alfa Laval Packinox Standard Combined Feed/Effluent Heat Exchangers began service in xylene isomerization units in the mid-1990s. By 2000, some 35 Alfa Laval Packinox Standard Combined Feed/Effluent Heat Exchangers had been installed in paraxylene production plants. For xylene isomerization, Alfa Laval Packinox offers against S&Ts the advantage of capital savings on installation, transport, foundation and piping, in addition to economizing fuel on associated process equipment in operation.
