LO-CAT® process as a claus tailgas cleanup unit
In 1997, Western Gas Resources selected the LO-CAT® process to treat the amine acid gas generated in their Pinnacle Gas Processing plant located in Tennessee Colony, TX. When the facility’s processing demand exceeded the LO-CAT capacity (2 LTPD of sulfur), Western Gas installed another LO-CAT unit having a capacity of 7 LTPD. In the summer of 2000, Western Gas once again forecasted that future processing requirements would dramatically exceed the sulfur removal capacities ...

Optimisation of a sulphur recovery unit
Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT® unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not presenting any operating problems. However, this is not Suncor’s operating ...

Optimal SOx reduction without rare earth for partial- and full-burn units. SOx reduction additives are designed to capture and remove the oxidized sulfur compounds present in the FCC unit regenerator and release them in the FCC riser. On release, the sulfur exits the FCC unit as hydrogen sulfide, along with the cracked products in the reactor effluent. The hydrogen sulfide is processed in the gas plant downstream of the FCC unit. Extensive studies in the 1970s looked at the ...

Sulfur recovery is a crucial process in various industries, especially those involved in refining petroleum and natural gas. Sulfur containing compounds in these raw materials can be harmful to the environment and pose health hazards. The Claus process, a time-tested and reliable method, effectively recovers sulfur from these sources, ensuring cleaner emissions andcompliance with environmental regulations. Evonik is a complete-package SRU & TGTU catalyst supplier. We manufacture ...

Valve solutions for sulphur applications
How to select a valve for sulphur applications? We asked our expert Vincent Wang to answer this frequently raising question. What are the key points to address when selecting a valve for sulphur applications? When we talk about sulphur valves, in most cases they are used in the sulphur recovery unit. Various processes in refineries and gas plants produce gases that contain hydrogen sulphide (H2S) and the amount of sulphur is legislated to meet HSE and gas piping specifications, ...

Intelligently predict and manage sour water corrosion in refinery applications
One of the primary concerns in refinery operations, especially when processing sour crudes, is management and mitigation of NH4HS (Sour Water) corrosion in hydrocrackers, hydrotreaters, FCC and other unit circuits. Honeywell's Predict-SW software, a byproduct of more than 15 years of intense Joint Industry Project (JIP) research, provides an easy to use framework to quantify NH4HS corrosion as a function of key process parameters across the refinery value chain for commonly used ...
