Hasyılsan Construction provides comprehensive construction, maintenance, and repair services for wellheads, manifolds, separators, heater-treaters, desalters, overflow tanks, emulsion breakers, produced-water injection systems, storage tanks, and well production pumps within the oil and gas production industry.
The company also delivers turnkey engineering, design, project development, fabrication, maintenance, and overhaul services for Rotary Tables and Tij Boxes, which are essential equipment in well completion operations.
SEPARATION SYSTEMS IN THE OIL INDUSTRY
Crude oil typically contains unwanted components such as water, gas, and emulsion—varying by field and well conditions. These components are removed through physical and chemical separation processes. Equipment selection depends on the fluid characteristics and production capacity of the station.
Main Types of Separators
1. Free Water Knock Out (FWK)
A vessel in which free water produced with crude oil settles and separates based on density differences.
2. Separators
Used to separate water and gas from crude oil.
They are classified as:
-
Two-Phase Separators:
-
Liquid–Liquid (Oil–Water)
-
Liquid–Gas (Oil–Gas)
-
-
Three-Phase Separators:
-
Oil–Water–Gas separation
-
They are manufactured in horizontal, vertical, and spherical designs.
Three-phase vertical separators are the most commonly used type.
3. Heater-Treater (Emulsion Breaker)
Used to separate water trapped in an oil-water emulsion formed during production.
The process consists of:
-
Chemical injection
-
Impact on distribution plates
-
Heating
-
Settling via density difference
Heater-treaters are manufactured in horizontal and vertical configurations.
4. Desalter
A system designed to remove salt content from crude oil.
Crude oil mixed with sweet water and chemical additives is exposed to an electrostatic field, allowing water droplets to coalesce and settle, removing the dissolved salts.
TANK TYPES AND FUNCTIONS
a) Production Tanks
Used for settling crude oil before pumping.
Measurements are taken every two hours to monitor production.
b) Test Tanks
Used to measure well productivity.
Calibrated so that each centimeter corresponds to one barrel for ease of calculation.
c) Produced Water Tanks
Collect separated water before injection into disposal wells.
d) Other Tanks
-
Diesel fuel tanks
-
Utility and fire-water tanks
-
Injection water tanks
