Product Development and Process Technology (PDPT)

The Product Development and Process Technology Centre (PDPT) of L&T Heavy Engineering is the focal point for technology development, primarily for process plant, power and nuclear plant equipment businesses. It also caters to strategic businesses like marine & aerospace for special projects requiring technological synergies. PDPT contributes towards developing cutting edge technologies which keep us at the forefront in process & power plant equipment businesses.

Some of the products for which in-house proprietary designs have been developed are Cored Brick Heaters for hypersonic Wind Tunnel, Nuclear Steam Generators for PHWR plants, Shell & Tube LNG Vaporizers for LNG Re-gasification terminals, High Temperature Heat Recovery (HTHR) Exchangers for Cracker plants, Moisture Separator Reheaters (MSR) for nuclear power plants and Waste Heat Boiler for Ammonia burner in Nitric Acid plants.


PDPT is based in the Powai Campus of L&T and comprises of a group of multi-skilled engineers with specialization spanning a variety of domains. Depending on the nature of the project; cross-functional teams are formed consisting of experts from multiple areas. The group of highly motivated engineers has combined expertise covering:

  • Thermal & Hydraulic Design
  • Flow-Induced Vibration (FIV) Analysis
  • Computational Fluid Dynamics (CFD) Analysis
  • Mechanical Design
  • Static and Dynamic Stress Analysis
  • Fatigue Analysis
  • Creep Study
  • Fluid Structure Interaction (FSI) Analysis
  • Simulation of manufacturing processes such as welding and forming
  • Chemical process simulation & chemical reaction engineering
  • Fitness for service assessment


Our technical prowess has been recognized globally and there are continuous interactions with research fraternities / academia and their consultation services are utilised in projects.

PDPT stays at the forefront of the technology spectrum, facilitating absorption and transfer of technology for the entire organisation. PDPT also keeps abreast of the latest global developments in related areas, which provide inputs for undertaking new developmental projects. Regular technology scan and study projects in emerging areas such as Gasification technologies, Methanol Economy, micro- process technologies, fertilizer & refinery processes increase the understanding level of the organization in the targeted fields.

Utilising their expertise and technical understanding in the process equipment and heat exchanger domain, PDPT provides support in problem solving & troubleshooting.

Latest analysis and simulation tools are available such as:

  • HTRI & HTFS (AspenTech)
  • Aspen Plus and HYSYS for process simulation
  • ABAQUS for non-linear Finite Element Analysis (FEA)
  • ANSYS Fluent & CFX for Computational Fluid dynamics (CFD) analysis
