Hydrogen sulfide removal from sour associated gas

In November of 1999, PT Pertamina (Indonesia’s staterun oil company) installed the LO-CAT® II Hydrogen Sulfide Oxidation Process for their Mudi Field in East Java, Indonesia. The oil production operation at the Mudi field was producing up to 11 MMSCFD of sour associated gas. This associated gas was to be used to strip additional H2S from the sour crude and to generate power in 3 gas fired turbines. Pertamina investigated several alternative sulfur recovery options, ...

Wet gas sulfuric acid - profitable sulfur management

The WSA technology is an excellent alternative to the Claus technology for sulfur management within oil refining, coal gasification, gas sweetening etc. High steam production, feed flexibility, ease of operation, and low CAPEX & OPEX are some key benefits for the operator when selecting the WSA technology. Today we have +130 references world wide.

Harsh rooftop testing ensures the performance of Neles™ valve controllers

Q: How do you verify that your valve controllers will operate in varying field conditions for years? We verify our valve controllers and actuators at our own field-testing system on the rooftop of our Valve technology center in Vantaa, Finland. We have several different types of valve positioners and actuators installed on the roof. This is long-term testing; all of the devices are here in the wintertime in cold temperatures and in the summertime when the temperatures can be ...

4 simple ways to convert turnarounds into profitable tower upgrade opportunities

With planned outages commonly occurring at intervals of 2-5 years, a refinery turnaround is a prime opportunity to replace column and separator internals with the newest available technology. Planning for an outage with a “replacement-in-kind” strategy will address lost performance from refinery equipment due to normal wear and tear. However, most column internals can be upgraded for higher capacity, more flexibility, or greater efficiency at close to the same cost ...
