The design of process control allows maintenance of process capability in response to operational actions.
Material data are of basic importance for the design, operation, and maintenance of process plants.
For the development and maintenance of process models, experimental data with a high information content are required.
Maintenance of process components on offshore and onshore petroleum facilities is therefore crucial in order to avoid major accidents, such as Piper Alpha and Texas City.
The purpose of this book is to provide practical guidance on issues to do with the design, operation, and maintenance of process facilities, including chemical plants, oil refineries, offshore facilities, and pipelines with a focus on safety issues.
However, the accumulation of VFA and the decline in pH demonstrated the instability of aceticlastic methanogenesis in the conditions under which reactor DVX was operated, thereby reflecting the importance of SAOB for the maintenance of process stability in methanogenic systems with high ammonia concentrations.
At the coarser scale, one important interpretation, discussed below, advocates a primary linkage of biodiversity to the maintenance of ecosystem processes — what might be called the "bio-processes" approach.
They are multicellular and composed of specialized cells, arranged in a single layer, for the maintenance of life processes.
This includes an assessment of the impact of some of the major properties of coal on the design, performance and maintenance of gasification processes.
Yet Norton (2001) and others, in linking "biodiversity" to maintenance of ecosystem processes, move back to the resource perspective — as evidenced in Norton's reference to three phases of "biological resources", not "biodiversity", protection.
