Establishing operations

Establish operating conditions, i.e., flow rates, temperatures, pies-sures and compositions of fluid over the life of the system. This may involve several cases. 

This section is concerned with errors that are often classified as "violations," that is, situations where established operating procedures appear to have been deliberately disregarded. Such violations sometimes arise because the prescribed way of performing the task is extremely difficult or is incompatible with the demands of production. Another cause is lack of knowledge of the... 

Total reflux exists in a distillation column, whether a binary or multicomponent system, when all the overhead vapor from the top tray or stage is condensed and returned to the top tray. Usually a column is brought to equilibrium at total reflux for test or for a temporary plant condition which requires discontinuing feed. Rather than shut down, drain and then re-establish operating conditions later, it is usually more convenient and requires less...

An owner/operator wishing to operate a new hazardous waste BIF is required to obtain an RCRA permit before beginning construction of the unit. The purpose of this permit is to allow the new BIF to establish operating conditions that will ensure adequate protection of human health and the environment. The BIF permit process consists of four operational phases pretrial burn, trial burn, posttrial burn, and final operating conditions. 

The committee notes that the laboratory tests established operating parameters for hydrocyclone operation that involve careful control of pressures and flows to achieve desired separation efficiencies. No tests were performed to demonstrate the robustness of hydrocyclone operation during the pressure and flow swings that might be expected during normal operations of a full-scale facility.

Establish Operating Experience And Demonstrate Applicability of Power Recovery Systems. 

The leader may become aware of confidential information while simultaneously facing outside demands for premature release of the team s findings. The leader should have interpersonal skills suited to interacting with strong personalities while avoiding clashes and maintaining confidentiality. The leader must be able to influence changes within an established operation. 

Production According to pre-established operating procedures with appropriate in-process controls, regularly validated... 

SCAQMD Rule 1141.1 Establish operating requirements for coatings and inks manufacturing. 

Pilot plants are often more hazardous than process plants, even though they are smaller in size, for many reasons. These include a tendency to relax standard safety review procedures based on the small scale, exceptionally qualified personnel involved, and the experimental nature of the research operations the lack of established operational practice and experience lack of information regarding new materials or processes and lack of effective automatic intedocks due to the frequendy changing nature of pilot-plant operations, the desire for wide latitude in operating conditions, and the lack of full-time maintenance personnel. 

Oxo plants employ mixtures of highly toxic, flammable gases under pressure at high temperatures and require strict adherence to established operating safety codes and emergency reporting procedures to local, state, and federal authorities. I11 the United States, carbon monoxide is classified as both an acute, fire, and sudden release hazard. 

Systems should be in place to control changes and evaluate the extent of revalidation that the changes would necessitate. The extent of revalidation will depend upon the change s nature, scope, and potential impact on a validated system and established operating conditions. Changes that cause the system to operate outside of previously validated operating limits would be particularly significant. 

In Table 7.5, the operational parameters of the tested PFIEBR, where x was calculated with Equation 7.31, and Bc, 1), and E were calculated with the help of the experimentally obtained breakthrough curves using Equation 7.32 and the established operational parameters F and < ), are shown. 

Determine the medium resistance Rm. Rm is the (true) y intercept in Fig. 14.3, approximately 0.24 x 10n m 1. (However, use this result with caution, because it is hard to establish operating conditions at t = 0.) It frequently happens that the intercept of the p/Qxq) line is negative. Such a result generally implies (1) migration of fine particles, with subsequent blinding of medium or cake, or (2) sedimentation on a horizontal filter surface facing up. 

A single human error with or without established operating instructions. Incorrect sequencing of events, improper valve positioning,prolonged or excessive cycles, materials transferred too quickly or to the wrong vessel. 

Two simultaneous human errors with or without established operating instructions. Same as above. 

Evidence of effective Development Testing can reduce the amount of subsequent User Quali-hcation expected by GxP regulatory authorities. The pharmaceutical or healthcare company will often endeavor to include in its User Qualification as many tests as possible from Development Testing. It should also reduce the time needed to commission the computer system on the pharmaceutical or healthcare company s site, as qualification can focus on confirming an already established operational capability.
