Personnel allocation for alkylation and spent acid units
Thread Content
The staffing requirements for the plant capable of producing 200,000 tons per year of alkylated products, as well as for the two units used in waste acid regeneration, are provided solely for reference in controlling production and processing costs. Staffing is also a crucial factor; an excessive number of employees leads to wasted human, material, and financial resources. Inadequate staffing can also affect production safety; therefore, I would like to share with colleagues the information regarding the staffing levels in alkylation units and waste acid regeneration units as observed in practice. The alkylation unit and the waste acid treatment unit were originally two separate systems, and many companies also divide them into two separate workshops. The staffing for these two workshops is as follows: Alkylation workshop (200,000 tons): a supervisor, an assistant supervisor, one technician, and three work teams ； Each shift has one shift leader, two main operators, and two patrol officers, for a total of 18 people. Waste acid workshop (25,000 tons): chief, deputy chief, one technician, three work teams ； Each shift has one shift leader, one chief operator, and three patrol officers, for a total of 18 people. The total number of employees in the above two workshops is: 18+18=36 people. However, the two workshops can easily be combined into a single workshop. The current operating model and staffing are as follows: a director and deputy director for the combined workshop, along with technicians. There are three work teams, each consisting of a team leader, a deputy team leader, three main operators, and four field workers; in total, that’s 30 people. This arrangement saves around 550,000 to 650,000 in human resource costs per year. The combined unit has been operating in this mode since June 2015, with no abnormalities to date; any sudden issues that arise are effectively controlled, and the overall operation remains stable without causing any negative impact on production. The staffing arrangement can be considered quite reasonable. Establishing a combined facility presents numerous difficulties; it is recommended to set up such a facility from the initial stage of construction of the acid waste treatment plant, as this facilitates integration better.
Combining the two sets of devices organically results in higher efficiency as well as better economic benefits.
Well, yes, with the corresponding technological upgrades, both the overall operating costs and production costs will increase.
The suggestion is good; we do separate our waste acids, and it indeed requires a lot of labor
Yes, combined units not only require fewer workers but also make management and coordination easier, offering significantly better overall efficiency compared to using them separately. The key is to have the technical personnel in place.
The combined unit offers good overall efficiency and high operational effectiveness.
To be specific, refining facilities are suitable for integration, while chemical plants are not
There’s disagreement on this – why isn’t the chemical industry suitable?
The operation of chemical plants varies greatly; for example, between polyethylene and polypropylene, there are high-pressure and low-pressure variants of polyethylene, and within low-pressure polyethylene, there are gas-phase and liquid-phase processes. The types of reactors, process flows, and operational approaches are all completely different.
With such a reduced staff, if a valve needs to be replaced or an emergency occurs, can people be deployed to handle it?
