A systematic Hazop procedure for batch processes, and its ...

01/01/2000  There is a lack of a formalised procedure for the Hazop of batch processes. Some case studies have been published which suggest how the procedure for continuous processes can be modified, or emphasise other approaches for reviewing the safety of batch processes. The issues concerned with batch process safety have been described in this paper, and a methodology

One approach, Hazard and Operability Study (Hazop), is a method of systematically identifying every conceivable process deviation, its abnormal causes and adverse hazardous consequences in a chemical plant. The technique was developed by ICI in the 1960s, and has been standardised for use in continuous manufacturing plants. Improvised attempts have been made to modify the continuous Hazop ...

A typical batch plant can be examined by dividing the process into three operational phases: charge, reaction, and discharge. A modified Hazop methodology should then be applied to the description of each phase. Although a need for this type of approach has been recognised, there is no published information to be found on an agreed format on how this should be done. This paper presents a ...

HAZOP ASEMS Online

One procedure for a batch HAZOP is called 'step by step'. In this procedure each batch process step is taken in turn, and the guideword study of the system is carried out for that step. After completing the study for the first process step the other steps are taken in sequence, using the same technique. The technique can be very repetitive but it is necessary in order to be systematic and ...

HAZOP: Batch Processes

HAZOP on a Batch Process. A batch process is one in which successive chemical / physical operations are carried out in a single vessel (under varying time-dependent operating conditions) until the feed changes to product. The standard approach, of examining a system line by line, is ideal for continuous processes but does not lend itself to the thorough examination of batch processes. 2 ...
