What Factors Need To Be Considered When Choosing The Location Of A Chemical Plant?

October 31,2022

Chemical plants have potential damage to the environment and surrounding residents in the production process. So what principles should be followed in the selection of chemical plants to reduce damage to the human environment and meet the construction requirements of the economy? The positioning of a chemical plant is faced with a planned plant and a realistic environment. So the problem to be solved is where to build this plant.


ⅠThe positioning of chemical plants generally follows the following basic principles:

(1) Excellent circulation conditions for raw material, fuel supply and product sales;

(2) There is an excellent collaborative environment in storage and transportation, public works and living equipment;

(3) Approaching a water source with sufficient water quantity and good water quality;

(4) There are convenient traffic conditions;

(5) There are good engineering sites and hydro-meteorological conditions.


ⅡBasic requirements for chemical plant location selection:

1. Factories should avoid locating in the following areas:

(1)Earthquake-prone areas;

(2)Class III self-weight collapsible loess area with thicker thickness;

(3)Mountainous areas vulnerable to floods, landslides, etc.;

(4)Mineral deposits with mining value;

(5)Areas that have an impact on the use of airports, radio stations, etc.;

(6)Nationally stipulated historical relics, biological maintenance and scenic tourism areas;

(4)Townships and other densely populated areas.


2.The principle of site selection:

(1)The site of the plant should be selected in an area with convenient raw materials, fuel supply and product sales, and an area with excellent cooperation conditions in storage and transportation, machine repair, public works and living equipment.

(2)The plant site should be close to a place with sufficient water quantity, good water quality and sufficient power supply.

(3)The plant site should be selected in a place with convenient transportation.

The selection plant should pay attention to saving land, not occupying or occupying less cultivated land, the area shape and other conditions of the plant area should meet the needs of reasonable layout of the technological process, and should leave appropriate room for development.

(4)The plant should pay attention to the natural environmental conditions, make a pre-evaluation of the impact on the surrounding environment after the plant is put into operation, and select the production area of the plant and the construction site of the residential area at the same time.

3. Interaction with the  surrounding environment

(1)The wind direction and the degree of mutual influence between the  construction project  and the surrounding area in terms of risk and damage should be considered first, and countermeasures such as azimuth adjustment, and adherence to safety distances and sanitary precautionary distances in accordance with national regulations should be adopted.

(2)Place factories in disadvantaged areas of the community based on prevailing winds.

When flammable and explosive production areas are arranged along the river, they should be located downstream of important buildings such as towns and water sources close to the river, and take effective measures to prevent flammable liquids from flowing into the river.

(3)Factories and enterprises that use or produce toxic substances and emit harmful substances should be located on the inferior side of the dominant wind direction or the upwind side of the minimum frequency wind direction in townships and residential areas throughout the year.

(4)Production equipment and auxiliary production equipment that may cause pollution to rivers and groundwater should be arranged in the downstream of towns, residential areas and water sources and in lower terrain.

(5)Enterprises that are sensitive to noise should be located on the inferior side of the minimum summer wind frequency and direction of the primary noise source around them.


4.Factory general plane safety layout:

The so-called general layout is to rationally plan and organize the various functional areas in the construction site after comprehensive consideration of the production process, transportation conditions, safety, hygiene, environmental protection, construction, management and other factors, combined with the natural conditions of the site and after multiple plans and comparisons, the plane orientation connection between buildings, structures and various passages. The functional zoning of the construction site is the most important part of the overall layout, according to which the mutual orientation and transportation relationship between the various functional zones can be confirmed. Factory layout is a positioning problem of relative orientation between components inside the factory. Its basic task is to confirm the spatial orientation of various machines and equipment in the production process based on the internal and external conditions of the factory area, and to obtain the most reasonable flow route of materials and personnel.
