Plant startup commissioning

Commercial plants Over 100 EO/EG plants using the SD technology have been built. Among the four world s largest capacity MEG plants, three were engineered by SD at 700,000 metric tpy MEG each. Two of these plants were commissioned in 2009, with the third scheduled for startup in the fall of 2010. 

On account of the nature of brainstorming, the study process offers a creative concept to find new deviation causes and consequences, which can be helpful in suggesting better control measures. It can be used in various plant stages/modes (only accurate sufficient information is necessary). It finds its applications for Plant design study Normal plant operation Reduced output operation Normal startup Normal shutdown operation Emergency shutdown operation Plant construction/commissioning Special operating mode...

The sequence of the remainii steps of synthesis gas preparation is CO shift conversion, removal of H2S and CO2 by Rectisol wash (cold methanol), and liquid nitrogen wash. As in other partial oxidation processes, the H2S is converted to elemental sulfur. Ube Industries, Japan, commissioned a 1,500-tpd ammonia plant in 1984 using the Texaco coal gasification process. An energy consumption of 10.9 Gcal/tonne of ammonia is stated this is lower than the normal quoted f ure of 11.6 Gcal/ tonne of NH3 for coal-based processes 131]. Another 1,000 tpd coal-based ammonia plant is scheduled for startup at Wehei, China, in 1996. 

Commissioning is the activity whereby the installed hardware of a new plant is transformed into an operational facility. Most works on industrial chemical technology ignore the subject. However, it is an extremely important topic, and the successful startup and subsequent operation of a new plant are critically dependent on the approach taken toward...

TURNKEY CONTRACT, where a single principal contractor has the overall responsibility for the design and construction of the nuclear power plant. This responsibility often extends to the commissioning and startup of the station, and to the provision of the initial fuel supply. The Turnkey Contractor is most often the nuclear steam supply system vendor, but an... 

Following design and construction of the plant, plant tests, including startups, operation at design conditions, and shutdowns, are carried out prior to commissioning of the plant. 

Pre-startup reviews sometimes identify documentation problems. During the construction and commissioning of a plant there is usually considerable pressure just to get the plant completed and up and running. Hence the record-keeping part of the project may slip. If, in the judgement of the review team, some of the missing documents are important to safety, they must ensure that those documents are completed and issued before the plant is started.
