Implementation of ENCON Strategy • Designated Energy Manager • External Energy Audit By Original Licensors & PCRA • All discipline Energy cells • Regular monitoring of Energy consumption, Steam balance & Overall performance • Targets reviewed periodically for compliance • Special budgetary support
Implementation of ENCON Strategy • Employees participation ensured through awareness programs, incentives on suggestion scheme. • Interaction with Fertilizer industry for continual improvements • Consultation with machinery and catalyst vendors for performance review and upgrades • Liaison with Licensor for energy improvement options
Implementation of ENCON Strategy • Energy Cell Objective: Energy Auditing, Plant Health, Performance Monitoring • Each Energy Cell consists of Experts from • Technical (Coordinator of the Cell – Energy Manager) • Production • Instrumentation • Maintenance
ENCON and Cost Reduction are monitored through • Change in operating practices without any investment • Minor process modifications involving small investments • Major energy saving retrofits involving large investments • Monitoring & Optimization of plant performance and energy consumption on daily, monthly, and yearly reports basis • Periodic equipment performance evaluation, steam balance • Minor modifications implemented as per Energy Work Request (EWR), Suggestion Schemes • Development of In-house Computer Softwares • Inside/outside training programs for Plant Engineers and Operating personnel
Strategy for Energy conservation • Advanced Process Design • Complex Integration • Improve Operating Practices • Major Modifications • Minor Modifications
Advanced Process Design • High performance Catalysts • Process Equipment based on Advanced Technology (Ex: G.T. for Process Air Compressor and MP Condensate Stripper in Amm-II etc.) • Two –stage GV CO2 Removal System • Optimized Process & UtilityInterconnections • Advanced and Reliable Instrumentation & Control System
Complex Integration • Optimized use of Steam & Power consumption for peak load of generators • Use of Surplus Steam • Common Steam & Electrical Power Supply • Common Utilities & Offsite • Common Finance & Admn
Improved Operating Practices • Periodic In-house & External Audit • Scheduled check of NG/SG/Steam leaks/NH3 leaks and on-line rectification • Accelerated start up using the interconnections • Thrust for power & water saving in non-essential areas • Export & Import surplus Synthesis gas to minimize venting during upsets • Optimize NG/Naphtha ratio for maximum Urea production & NG consumption, no CO2 venting
Additional Steps to improve Operating Practices • Rotary machines overhauling based on the performance evaluation, which results in substantial improvement in their efficiencies. • Plant wise steam balance and Overall steam balance helps in best utilization of steam and avoiding steam venting • Steam to Carbon ratio is being monitored on regular basis and is maintained near design value of 3.3. • Periodic steam lines insulation survey helps in reducing the loss of heat to atmosphere • Replacement/maintenance of leaking/passing steam traps
Introduction IFFCO in a big way has gone for Energy Saving Project in all its Ammonia plants at various units in consultation with the process licensor M/s Haldor Topsoe, Denmark. The schemes have been successfully commissioned between 2005 to 2007 in a phased manner and the benefits have been achieved by way of reduction in the specific energy consumption per metric ton of ammonia.
Energy Saving Project - Background • GOI implemented the New Group Pricing Schemes for Urea Fertilizer Industry w.e.f. April 2003. • Energy Norms were made more stringent. • Incentive were provided for Energy Efficient Plants. • No mopping of Energy Efficiency and no recognition of Capital Invested. • In order to lower the Energy Consumption below the prescribed Norms Energy Saving Project was envisaged for all the five Ammonia Plants at Kalol, Phulpur-I, Phulpur-II, Aonla-I and Aonla-II Units.
Energy Saving Project - Background Project was bifurcated in two Phases viz. Phase-I and Phase-II Project for ease of implementation and to accrue the early benefits
