Chapter 11.4.3 Handling excess steamDescriptionSteam at various pressures is used and generated on an integrated production site for heatingrequirements and for driving various mechanical equipment. Depending on the specificproduction site, excess steam might be generated. This is handled according to the followingpriorities:1. generally, avoid pressure reduction without using the energy2. try and adjust the whole steam system in order to minimise excess steam generation byminimising the overall consumption3. use of excess steam on-site or off-site4. as a last option, using steam for generating only electrical power, if local factors prevent theuse of excess thermal energy on-site or off-site.For an example of using LP steam for cooling, see Section 9.4.2 “Recovery of residual heat forchilling process water”.Achieved environmental benefits• reduced energy consumption.Cross-media effectsNone believed to be likely.Operational dataNo information provided.ApplicabilityGenerally applicable.EconomicsNo information provided, but cost benefits can be assumed.Driving force for implementationReduced energy consumption and cost benefits.References to literature and example plants[154, TWG on LVIC-AAF, 2006]16 Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers
