Objective

During our survey of a leading Global Tyre and Rubber MNC we found the potential to improve the condensate and flash steam recovery in the plant i.e:

  1. Potential to recover flash steam which was venting out from the condensate collection tank
  2. Potential to enhance the heat content in the condensate being recovered

Issue

The plant had a conventionally designed condensate recovery system comprising a collection tank (open to the atmosphere) and a centrifugal pump to pump the condensate. Due to this conventional design, flash steam was venting from the collection tank and condensate was losing its heat due to higher residence time in the tank and higher radiation losses.

Root Cause

Ineffective design of the condensate and flash steam recovery system

Our Solution

Our team helped redesign the condensate and flash steam recovery system. We computed the recoverable condensate and flash steam quantities, selected and sized the recovery system and defined the necessary modifications required at the site in the piping. Based on our recommendations the plant made the necessary changes including installing a pressure power pump unit with flash separation vessel for condensate and flash steam recovery.

Benefits:

  • Condensate return at high temperature 95oC +
  • Use of flash steam in LP process
  • Water saving 10,000 Ton/annum
  • Monetary saving 1,300,000 THB/Annum (40,000 USD/Annum
