Chlorine Leakage from Control Valve in Charging Station

Pipeline: A Case Study

Rajkumar Patil, S. N. Teli, L. M. Gaikwad* Mechanical Engineering Dept., SCOE, Navi Mumbai, India

Abstract This paper describes accidental release of chlorine gas from control valve through a

chlorine charging system in a green color pigment manufacturing chemical industry. The

chlorine gas dispersed over the entire reactor floor and nearby area at night time shift work. This paper presents root cause analysis of the incident. Corrective and preventive

measures are also discussed. Finally, conclusions reached with recommendations are

drawn for industrial facilities for handling and prevention of chlorine.

Keywords: Chlorine, control valve, leakage

Reliability Analysis using Fault Tree Criterion: A Case

Study of Inlet Guide Valve of Centrifugal Air Compressor

Tushar J. Padave*, Alok P. Tibrewala Mechanical Engineering, University of Pune, India

Abstract Inlet guide valves (IGVs) are one of the most important components in centrifugal air

compressors. Evaluating and analyzing the workings and potential failures of IGV ensures efficient working of centrifugal air compressor by eliminating the potential

failure modes. Also, analyzing the risk of the component helps in ensuring reliability and

safety, which can in turn ensure higher availability and utilization of the system as a

whole. Reliability of IGV will directly affect the safety and operational availability of the

centrifugal air compressor. This paper includes the basic concept behind inlet guide vane and fault tree analysis (FTA). Also included is the qualitative FTA of the IGV actuation

mechanism.

Keywords: fault tree analysis, centrifugal air compressor, inlet guide valve,

reliability analysis

Abstract The aims of this study were to measure the workplace heat stress and noise intensity

levels in different sections of the foundries. The study was carried out in a small

industrial city of southern peninsular of India, known for cluster of foundry establishments. The heat and noise level were measured in melting, fettling, gas cutting,

heat treatment furnace, and administrative sections measuring the dry bulb temperature(TDB °C), wet bulb temperature (TWB °C), globe temperature(TG °C), wet bulb

globe temperature(WBGT °C), and the relative humidity(RH%) at the work places. The

noise level measurements were also carried out using portable integrated sound level meter. Extremely high levels of WBGT index was found in gas cutting section with an

average of 33.73 °C followed by 29.68 °C in melting unit. The mean WBGT mean values obtained in other sections were, 28.37 °C in heat treatment, 28.25 °C in fettling and

25.84 °C in administrative sections respectively. The mean WBGT index levels are

significantly higher (p < 0.05) in gas cutting, melting, heat treatment and fettling sections compared to the administrative section. The prescribed standard threshold limit value

(TLV) of WBGT level was high in gas cutting, melting, heat treatment and fettling units.

The values of equivalent noise levels were under control as per OSHA guidelines in all the process sections. The heat and noise may increase the health risk of worker with

reduce the efficiency and consequently affect the production of the unit. The recommendations should be taken as indicative of stress areas and workers should be

under constant medical supervision.
