ENERGY SAVINGS
Our engineering team has a knack for saving energy, leverage best practices across industry lines.
We can help your company identify the best ways to save energy on multiple fronts. Below is an example of slides from a presentation that is available for refinery clients to save energy. An abridged copy of the presentation is available to potential clients by contacting us.
EXAMPLES OF WHAT WE CAN DO
Below are some examples of what we have done on past projects, or can do for you to save energy, or synergistically improve the commercial value of your operating units. Many of these opportunities also introduce emissions savings directly or indirectly to your facility.
- Wellpad / Oil Production: Optimize operating pressures based on the crude assay to increase oil production and reduce emissions. Add an exchanger to the larger (> 1000 bpd) facilities to reduce gas consumption, reduce emissions, and improve oil recovery.
- Refineries: Demonstrate the best use of existing equipment through monitoring of fouling versus ideally clean exchangers to predict the best times to pull and clean tube bundles.
- Distillation: Apply midstream practices to downstream customers in refineries, petrochemicals, and blending operations, taking advantage of weather conditions to drive improved separation a lower energy intensity.
- Towers to Condensers: As illustrated above, oversize your tower overhead lines, or replace overhead lines on existing systems, to improve condenser performance or reduce condenser area requirements.
- Pinch Technology: Run pinch analysis on your complex systems and determine the best use of exchangers or the addition of exchangers to improve overall heat recovery.
- Condenser Bottlenecks: Analyze systems with known condenser bottlenecks and adjust operating parameters and heat recovery to drive toward the best balance of commercial value vs. energy intensity.
- Reboiler pinch-outs: Analyze reboilers and heat integration schemes to deliver better results with improved heat recoveries, the introduction of new exchangers, and improve heat transfer performance for tighter LMTD with tube inserts, twisted tubes, or other exchanger technology that doesn't require a new full exchanger.
- Steam Users: Evaluate desuperheating steam to your steam users
- Hot Oil: Evaluate hot oil systems and optimize heater efficiency by monitoring hot oil consumer valve controller positions. Usually nets percentage levels improvement in heater efficiency, and can help reduce pumping power requirements in some cases.
- Salt Domes: Brine injection facilities, review operating pressure of brine delivery system, and optimize pressure requirements to pumping power consumption, successfully performed and saved nearly $100,000 / yr at on facility.
- Hydrotreaters: Introduce new "looped" heat integration scheme on reactor effluent upstream of stripper/stabilizer for reducing reboiler requirements, and improving cooling performance before LPCS.
- Different Heat Integration: Add feed/condenser circuits, applying typical refinery heat integration into midstream units, and debottlenecking condenser circuits while simultaneously shaving reboiler duty. We have also helped in the design of hip reboilers where conventional heat integration methods usually fail to identify opportunities.
