Steam condensate recovery
Thread Content
1. The importance of condensate recovery: The thermal energy contained in steam consists of sensible heat and latent heat. When steam releases its latent heat and turns into condensate, the heat contained in this condensate accounts for 20% to 30% of the total energy of the steam. The purpose of condensate recovery is to reuse the heat contained in the discharged condensate in other industrial processes, as well as to use the condensate itself as water for replenishment, thereby maintaining the highest efficiency of steam-related equipment. 2. Benefits of condensate recovery (including heat recovery and condensate recovery) a. Benefits of heat recovery: (1) Saving boiler fuel; (2) Improving boiler efficiency. b. Benefits of condensate recovery: (3) Saving industrial water; (4) Reducing treatment costs. c. Other benefits: (5) Reducing air pollution due to less consumption of heavy oil; (6) Steam traps produce no operating noise. 3. Methods of condensate recovery: (1) Open-type recovery. Basically, it is recycled in a closed system with pump (2). Methods for recovering condensate using a GT or high-pressure pump: (1) Direct recovery via a drain trap; (2) Adding a centrifugal pump to the drain trap; (3) Using a condensate recovery pump; (4) Using a high-pressure pump to send the liquid back to the boiler. 5. Calculation of condensate volume: Qs = Q × SpHt × Δt / Hfg. Where Qs is the condensate volume in kg/hr, Q is the amount of product processed per hour in kg/hr, Δt is the temperature difference between the inlet and outlet of the product, SpHt is the specific heat capacity (for water, this value is 1), and Hfg is the latent heat
Our organization also faces the issue of reusing steam condensate. The main question now is: what should be done with the steam condensate once it has been collected? If it’s used merely for water conservation purposes, the benefits are not significant enough to justify the effort Who has a better use for it?
Recycling is an inevitable trend, and manufacturing processes must also evolve in a more sustainable direction. Hope the chemical industry can change its image of causing pollution and high energy consumption:victory:
The 13 kilograms of steam condensate from our workshop is flashed, and the resulting steam is incorporated into the 5-kilogram steam pipeline system, while the condensate is recovered.

We are recycling kinetic energy!
Closed-loop recycling fails to address the cavitation problem in water pumps
In the field of energy conservation, recovering condensed water involves not only recovering the water itself but also its heat, which is then incorporated into the waste steam recovery process; typically, after flash evaporation, the steam is recovered by steam power systems
The condensate water from our equipment is pumped to the desalinated water system for reuse
The heat source at the bottom of the liquefied gas refining unit’s towers comes from the superheated steam generated within the unit; after the steam releases its heat, the condensed water is discharged into the unit’s waste drainage system, resulting in a waste of both the condensed water and its heat energy. Due to the good quality of the condensate water, it is possible to consider feeding it into the desalination system of the plant for reuse. It saves water resources while recovering and utilizing heat.
It is recovered here after heat tracing condensation or in the condensation pipeline
