The Challenge

PETROLTERV, a Hungarian engineering design and consulting company, was tasked with revamping the gas treatment technology at Hungary’s largest underground gas storage facility to meet new European (EN) standards. The new standards imposed more stringent hydrocarbon and water dew point requirements for natural gas handling systems than what was previously prevailing in Hungary. The site had three gas treatment trains each employing a TEG (Triethylene glycol) dehydration unit and a low temperature separation (LTS) unit which employed a propane refrigeration system and brazed aluminum heat exchangers (BAHX).

About The Customer

PETROLTERV is an engineering design and consulting company founded in 1967 and based in Szeged, Hungary. The company traditionally delivered projects for the oil and gas industry; however, with the aid of state-of-the-art software such as aspenONE Engineering, they also serve other industries including chemical, agriculture and heavy. PETROLTERV consists of in-house teams focused on process control system engineering, mechanical engineering, equipment design, civil engineering, electrical engineering and GIS/geodesy. Using the expertise of these teams, PETROLTERV can provide full service on complex projects for their clients, and consider environmental responsibility during the preparatory and planning phases of those projects. Their mission is to provide high-quality and reliable engineering designs and services, as well as consultancy for their existing and future partners.

The Solution

PETROLTERV used the aspenONE Engineering suite from Aspen Technology, which included Aspen HYSYS and Aspen Exchanger Design & Rating (EDR), to rigorously simulate and design improvements to their gas treatment process that met new EN standards. The team was able to rigorously simulate the propane-based refrigeration system and the brazed aluminum heat exchanger operation to determine new design alternatives in order to meet new stringent standards. The following key modifications were proposed to meet the new requirements: Increase the capacity of the refrigeration units, Replace the refrigerant medium, Change existing BAHX units and install filter separators to protect the new heat exchangers.

Operational Impact

PETROLTERV was able to save up to $400,000 USD on CAPEX of the Zsana UGS revamp project via greater design accuracy offered by the integrated aspenONE Engineering suite of products.
After using the suite, PETROLTERV no longer has to outsource a large number of engineering projects, such as air cooler design, pressure safety valve sizing, etc. Completing more work in-house has enabled them to bring down their project costs, as well as deliver those projects on time and on budget.

Quantitative Benefit

Saved up to $400,000 USD on CAPEX via greater design accuracy
Reduced costs by enabling PETROLTERV to perform design projects that were previously outsourced
Completed projects on time and on budget
