Steam Condensate recovery

External to the boiler itself are various pre-boiler and post-boiler water subsystems. These include the MU water pretreatment system, FW supply system, and steam-condensate recovery system, again of varying complexity depending on the design and size of the boiler.

Condensa.te Recovery Pumps. The condensate recovery pump is a unique design that utilizes a motive steam or an air supply to move condensate. It can be appHed to capacities up to 23,000 kg/h (50,000 lb /h), providing valuable recovery of condensate or other Hquids, which otherwise would be wasted. 

Our example system has a flow-controlled feed, and the reboiler heat is controlled by cascade from a stripping section tray temperature. Steam is the heating medium, with the condensate pumped to condensate recovery. Bottom product is pumped to storage on column level control overhead pressure is controlled by varying level in the overhead condenser the balancing line assures sufficient receiver pressure at all times overhead product is pumped to storage on receiver level control and reflux is on flow control.

The condensate return system is a post-boiler section system that includes all steam traps, condensate lines, associated manifolds and valves, condensate receiving tanks, save-all tanks, condensate pumps, and other auxiliaries for condensate recovery. 

Flash steam and heat recovery systems provide a useful and simple means of recovering both heat energy and steam condensate that would otherwise be lost by BD. The capital cost for an average sized industrial boiler house is relatively low, and capital payback periods are usually within 12 to 24 months. 

In ammonium phosphate and mixed and blend fertilizer (G) production, another possibility is to design for a lower-pressure steam level (i.e., 42-62 atm) in the ammonia plant to make process condensate recovery easier and less costly. 

It is of interest primarily for very uniform ultra-thin films and coatings (0.002-5 mils) in applications such as electrical resistors, thermistors, thermocouples, stator cores, connectors, fast-sensing probes, photo cells, memory units, dropwise steam condensers for recovery of sea water, pellicles for beam splitters in optical instruments, windows for nuclear radiation counters, panels for micrometeorite detection, dielectric supports for planar capacitors, encapsulation of reactive powders, and supports in x-ray and optical work. Any significant growth would depend upon a major breakthrough in process techniques and a consequent lowering in price. 

The surface condenser is an improvement on the barometric condenser, because it permits recovery of clean steam condensate. Other than this factor, the old-fashioned barometric condenser is more efficient than the more modern surface condenser. 

Production of heat energy at Rohm Haas has been improved by better control of combustion in boilers, cleaning and maintenance of boilers and process heaters to maintain their efficiency, elimination of steam leakages, steam trap maintenance, and improved condensate recovery (4).
