Energy Efficiency Review

This is a brief energy usage study of an industrial plant or building. Based on the review, recommendations are made for changes that could be implemented to improve the energy efficiency of the site. This service is ideally suited to small and medium sized plants or buildings.

Energy Audit

This is a detailed energy study which provides:

• A detailed energy usage survey
• Energy efficiency evaluation
• Development of energy targets
• Develop energy index benchmark (optional)
• Identifying energy saving opportunities including cost benefit analysis.
• Enman provides three level of energy audits, which are, Type 1, Type 2 and Type 3 as per the Australian standards AS/NZ 3589:2000

Energy Efficiency Study

The objective of this study is to identify energy saving project opportunities with a comprehensive recommendation and action plan. This is similar to an energy audit without energy usage database.

An energy efficiency study is recommended if there is no interest in an energy database and accounting but interest mainly in energy efficiency improvement.

Carbon Trading and Verification

Enman has extensive experience in energy and carbon reduction. Enman assist their customers in the following;

• Energy saving certification in NSW
• Energy saving verification at the conclusion of each energy saving project

Steam and Power Balance Technical Study

Enman provides a comprehensive steam analysis for a process or overall plant. When multiple steam headers with different pressure are being used with back pressure turbine, a steam and power balance is essential for efficient operation. Steam balance can lead to steam benchmark development of major steam using process.

Benefit from Steam or Steam and Power Balance:

• Energy saving through change of operational practice.
• Energy saving through optimal balance of steam and power
• Improve major steam using process plant efficiency
• Heat recovery
• Reduce loss of energy in piping and equipment through insulation
• Condensate recovery
• Steam trap maintenance

Process Integration Technical Study

For large plants process integration is an essential technique for maximising the operating efficiency. Correct integration minimises the required amount of heating and cooling utilities.

Pinch Analysis is a tool used to set targets for required amount of utilities. The following steps are performed in a pinch analysis.

1. Perform site mass and energy balance.
2. Identify heat sources and heat sinks from mass balance.
3. Select a minimum approach temperature to identify utility heating/cooling
   targets and pinch points.
4. Examine current heat exchanges to identify sources of waste and opportunities.

Conceptual Design

This is a new approach to design your food and beverage plant:

By integrating the process and utilities systems, and maximising the use of existing utilities equipment the conceptual design proposed will not only minimise additional running costs of the extension/new plant, but reduce project capital costs.

Benefits:

• Reduced capital costs of utility plants
• Reduced ongoing energy cost by up to 30%
• Reduced environmental impact

When to Use?

The best time to carry out conceptual design work is when you are revamping or extending your plant, or building a new "grass root" plant.

Enman's Conceptual Design Service Provides You With:

• Energy Balance
• Quantification of thermal and refrigeration loads of each major process unit.
• Evaluation of each process unit to ensure its energy efficiency is optimal.
• Simulation of plant utilities demand profiles of:
  • - Steam Load
  • - Hot Water Load
  • - Chilled Water Load
  • - Refrigeration Cooling Load (direct and indirect loads)
• Identification of possible energy saving opportunities by integrating process and
  utilities systems.
• Process utilities integration analysis.
• Optimise the use of current and new equipment to reduce capital cost,
  while meeting plant requirements.
• Automation and optimal control of utilities in accordance with process demands
