Flowserve Integrates Energy Advantage Program at Heide Refinery

Published on: 

Adhering to Flowserve’s Energy Advantage Program recommendations, Heide Refinery is expected to reduce its power consumption by more than an estimated 2,000 MWh per year.

Heide Refinery partnered with Flowserve Corp. to implement its Energy Advantage Program (EAP)—a data-driven engineering evaluation process that optimizes pump and valve power consumption with minimal disruption to existing processes. Heide will leverage this flow control capability to reduce carbon emissions, increase energy efficiency, and lower ownership costs.

An initial Flowserve assessment identified and analyzed Heide Refinery’s largest energy-consuming flow loops and clarified potential savings. Next, Flowserve’s engineers installed flow control solutions and provided recommendations for improved energy efficiency and performance tailored to Heide Refinery’s current process requirements. With these recommendations, the company expects to cut back its annual power consumption by more than approximately 2,000 MWh.

Following the pilot’s success, Flowserve and Heide Refinery will continue their partnership to capture additional energy savings. The EAP will be expanded to include the optimization of new flow loops within the plant.


“We are thrilled with the initial results,” said Roland Kühl, Managing Director, Heide Refinery. “With Flowserve’s engineering expertise, we can achieve meaningful savings while also lowering our carbon emissions by over 1,300 metric tons each year.”

In July 2023, Flowserve announced that its butterfly valve, the Valtek Valdisk, has obtained licensor approval for use in pressure swing adsorption (PSA) applications following a 1 million-cycle endurance test. The butterfly valve is ideal for chemical plants, oil refineries, and similar facilities requiring control valves and complements Flowserve's offerings for PSA applications, joining the Valtek Mark One globe valve and Logix 3800 digital positioner. Valtek control valves and Logix automation contribute to equipment longevity and maintain gas purity in PSA skids.

Several key features of the valve include a double-offset disc that mitigates seat and disc wear, a high-thrust cylinder actuator and an eccentric-cammed disc. Its streamlined body design allows for a more compact overall PSA skid footprint.

The endurance test was conducted following licensor standards to replicate the harsh operating conditions of high-cycle PSA processes. The valve underwent 1 million open/close cycles with upstream pressures of 350 psi while monitoring seat and stem leakage. The test also evaluated the valve's sensitivity, repeatability, and linearity by following a defined control ramp. The valve shutoff reliability allows plant operators to maintain precise pressure in the PSA vessel and extract purer hydrogen, oxygen, and nitrogen (or other gases).

Prior to this testing, in January 2023, Flowserve supplied 400 pumps for Aramco’s Jafurah project, one of the largest commercial unconventional gas fields being developed in Saudi Arabia. The company is working with three engineering, procurement and construction companies who will deploy pumps, mechanical seals, and sealing systems for the project. These include the gas treatment and sulfur removal facilities, utilities and interconnecting systems, and the produced water and gas compression facilities.
