Supervisors rating

Again the process engineer must spend a large amount of time observing the operations in the plant and talking with supervisors and operators. Besides verifying which steps are the bottlenecks, he must determine if some of the other units must also be modified. For instance, a filter may be able to process 20% more material, but still be inadequate for the proposed new rates. If only the primary bottlenecks were removed, then the plant could still produce only 18,000,000 lb I yr, since this is the maximum amount that can be put through the filter. 

Labor rates may be obtained from the union contract or from a company labor relation supervisor. This person will know the current... 

A 1995 evaluation prepared by MSRDI and the Gas Research Institute (GRI) estimates that the capital costs for a portable MSRDI combination technology mercury treatment system would be approximately 400,000. Direct operating costs for a portable system controlled by two technicians and a supervisor were estimated to be 1600 per day of operation, assuming a treatment rate of 2 to 4 tons of contaminated material per day per site. Overall operating costs were estimated to range from 400 to 800 per ton, per site, including mobilization and demobilization costs (D16195P, p. 35). 

In our modem economic society, prices may vary widely from one period to another, and this factor must be considered when the costs for an industrial process are determined. It would obviously be ridiculous to assume that plant operators or supervisors could be hired today at the same wage rate as in 1975. The same statement applies to comparing prices of equipment purchased at different times. The chemical engineer, therefore, must keep up-to-date on price and wage fluctuations. One of the most complete sources of information on existing price conditions is the Monthly Labor Review published by the U S. Bureau of Labor Statistics. This publication gives up-to-date information on present prices and wages for different types of industries. 

A 70,000 ton/year, 22,000,000 plant was started up in 2001. Since then, it has been operating at capacity for an average of 7200 h/year. It is staffed by 25 full-time production workers ( 32/h), two maintenance workers ( 35/h), and four shift supervisors ( 39/h). All labor rates include payroll and plant overhead. The process consumes 530 kilowatts of electricity ( 0.045/kWh), 50,000 gal/h of water ( 0.15/thousand gal), and 8.75 tons/h of feedstock ( 0.78/lb). Maintenance materials are estimated as equivalent to maintenance labor. Royalties amount to 4.20 per ton of product. The property taxes, insurance, and administrative charges total 5.2% of the total capital investment. Find the direct and indirect annual costs for the plant. 

Table I is a typical daily operating report for the NFS Waste Tank Farm. It shows that temperatures, densities, liquid levels, air flow rates, etc. are observed and recorded at least three times a day. Any equipment malfunction or response to the continuously monitored alarms is reported at least once a day on a supervisor s summary report. With the required initialing of both the operator and the supervisor on each shift, at least six trained individuals are made aware of the operating status of the facilities daily. In addition, these daily reports are distributed to no less than four other responsible members of management for information and review.

November 1996 A NREMT/Health Technician at TOCDF has alleged to have been harassed by plant supervisors for suggesting suspected organophosphate poisoning of TOCDF workers based on the technician having observed increased numbers of bradycardias (slow heart rates) and atrioventricular blocks (delays or block in cardiac electrical conduction) amongst these TOCDF workers. 

NOTIFY supervisor if flow rate drops below 20 gpm. 

MONITOR cooling water flow rate to ensure water flow rate Is not too high. Cooling water flow rate is adjusted using vaive B4. if cooling water flow rate falls, supervisor must be notified.
