Specific Energy Consumption(SEC)
/ Enterprise Energy management
Specific Energy Consumption (SEC) – The Iron & Steel, Mining, Engineering, and Heavy Manufacturing Industries are the largest energy consuming sectors in the world, these businesses consume a lot of energy that results in an increase in inputs cost. The purpose of the study is to calculate overall monthly “Specific Energy Consumption or Total Energy Consumption” which can be done from the energy consumption data and production figures and to generate different MIS Reports like Key Performance Indicator’s such as Gcal, Kcal, Kgs, MWH, Energy Balance Production Summary reports of Plants, Plant Efficiency (based on Balance & Actual Production), Production Ratio’s from different plant operations, Consumption details of various material inputs/outputs like Coal, Electricity, Gas, Coke, LPG, Oxygen, Steam, TAR, Nitrogen, Water and etc.
One of India’s Leading Steel Manufacturer and having integrated steel manufacturing facilities from raw material processing plants to value-added product portfolio capabilities like wire rods, steel bars, round bars. All the products are made by combination of the art steel making technologies in integrated steel plants such as Sinter Plants (SP), Blast Furnace (BF), Coke oven plants (CP), Open hearth plants (BF-OHP), Basic oxygen furnace (BF-BOP), Electric Arc furnaces – either coal or gas based (BF-EAF),Corex, Pulverized Coal Injection and etc.
Some of the Key Challenges
- The current industry challenges are the need to enhance product quality, improve process efficiencies, reduce cycle times, reduce downtime, reduce wastages and rework, track products, ensure adherence to regulatory guidelines.
- Energy value limits are often exceeded and often thereby causing additional costs in the variable inputs, on other resources.
- It becomes difficult for users from different departments to collate information or collect operational energy values from all these different sources like SAP, MES, PLC, LIS, Control Systems and etc.
- Key performance indicators across the plants like Sinter, Blast furnace, Coke oven plants, Basic Oxygen furnace, and other plants are cumbersome to calculate, time-consuming and many times are done manually.
- Manual data entry on spreadsheets, Manual Data Entry & Data Consolidation on Excel Spread Sheets leads to prone errors and inconsistencies in values.
- Not able to co-relate actual energy consumption by an allocation of the actual use of energy in each of the unit’s operations in plants.
- Not possible to compare energy values, steam, power and gas emission efficiencies across each plant at the same time
- Manual interventions need lots of time to complete the entire data consolidation process and require a lot of human efforts which results in chances of error-prone reporting.
- Not able to view cost parameters which are linked to quantity generated as per ton basis, the management cannot take quick decision-making process with pricing and cost control.
Detailed Problem Statement
The major challenge is that all iron & steel industries are covered under Environment Protection Act as well as Environment Protection Rules & Regulations, wasting most of the time on inefficient process, high emissions of Co2 via the burning of fuels has a negative impact on energy balance which is not meeting their regulatory standards and etc.
In present plant, for calculation of above said “SEC” (Specific Energy Consumption) and data consolidation and generating various MIS Reports, there are more than 50 – 70 both parent and child departments’ which works to capture the Production, Quality, Consumption and Energy values ranging from 600 – 900 parameters in respective departments, plants level operations, and different equipment’s values with their specific type, item category, parameters and units-wise and it becomes difficult for operators to collate the information from different sources like, SAP, PLC, MES, distributed control systems, Lab Information Systems, and other disparate information systems
On regular intervals of time, each user will record the values, collect the data manually from various information systems and transfer the same information manually to an excel spreadsheet on daily basis and submit it to the plant heads for approvals via e-mail attachments.
The manual data collection and reporting however slowed their ability to make some process improvements and was prone to human error, breakages of formulas/links, questionable values, delay in approvals thus, became a time consuming process for merging the multiple spreadsheets to generate consolidated reports, reconciliation or rekeying the values, data analysis, decision support reports like Consumption Reports, Energy and Power Index reports, detailed summary reports, daily, weekly or monthly reports and was not able to express the level accuracy values and there was no way to correlate with the specific information in their integrated steel plants.
During the consolidation of these hundreds of spreadsheets for the business users, it creates a lot of confusion to identify or track the hanging excel files in the e-mails, where it is difficult to interpret what important and what’s not in these excels sheets where you are missing an important aspect of data set.
