挑战
Siirtec Nigi, an engineering and contracting company, was tasked by one of their customers to nearly double sulfur production capacity. The challenge was to find the optimal level of oxygen enrichment and set up controls to increase sulfur recovery unit capacity. The customer was anticipating expensive changes with a huge impact on equipment and processes. The key challenge was determining an operating envelope for optimal operations.
关于客户
Siirtec Nigi is an engineering and contracting company providing a range of services around oil and gas treatment, sulfur recovery, and acid gas removal. Their customers include many oil and gas companies and other international EPC contractors, both onshore and offshore. One of Siirtec Nigi’s customers wanted to nearly double sulfur production capacity.
解决方案
Siirtec Nigi used Aspen HYSYS to simulate the case study, conduct sensitivity analysis, and define a window of operating conditions. The simulation validated the original heat and material balance created using a different tool. Based on the HYSYS model, Siirtec Nigi proposed an increase from 50 ton/day to 90 ton/day in sulfur production capacity that required only minor equipment upgrades. The upgrades can be completed during a normal turnaround, rather than scheduling an additional, costly shutdown because the simulation showed the minimal changes required to achieve the desired outcome.

Case Study
Taking Oil and Gas Exploration to the Next Level
DownUnder GeoSolutions (DUG) wanted to increase computing performance by 5 to 10 times to improve seismic processing. The solution must build on current architecture software investments without sacrificing existing software and scale computing without scaling IT infrastructure costs.
Case Study
Remote Wellhead Monitoring
Each wellhead was equipped with various sensors and meters that needed to be monitored and controlled from a central HMI, often miles away from the assets in the field. Redundant solar and wind generators were installed at each wellhead to support the electrical needs of the pumpstations, temperature meters, cameras, and cellular modules. In addition to asset management and remote control capabilities, data logging for remote surveillance and alarm notifications was a key demand from the customer. Terra Ferma’s solution needed to be power efficient, reliable, and capable of supporting high-bandwidth data-feeds. They needed a multi-link cellular connection to a central server that sustained reliable and redundant monitoring and control of flow meters, temperature sensors, power supply, and event-logging; including video and image files. This open-standard network needed to interface with the existing SCADA and proprietary network management software.
Case Study
Refinery Saves Over $700,000 with Smart Wireless
One of the largest petroleum refineries in the world is equipped to refine various types of crude oil and manufacture various grades of fuel from motor gasoline to Aviation Turbine Fuel. Due to wear and tear, eight hydrogen valves in each refinery were leaking, and each cost $1800 per ton of hydrogen vented. The plant also had leakage on nearly 30 flare control hydrocarbon valves. The refinery wanted a continuous, online monitoring system that could catch leaks early, minimize hydrogen and hydrocarbon production losses, and improve safety for maintenance.
