subsea lines of AMS-10 and AMS-11 wells, during the production of gas from the
wellhead to the deep-water platform of Amistad Field, considering flow both in transient
and in steady state. This analysis was done by numerical simulation with the aid of
ANSYS-CFX software, which uses computational fluid dynamics (CFD). Hydrate
formation curves were constructed with the use of certain correlations and compared
with the pressure-volume-temperature (PVT) analysis of the gas. For this, the properties
of the gas and the production water were included, together with the water of the medium
surrounding the flow lines. In addition, it was analyzed the possibility of using alternative
materials less thermally conductive compared to the original one used in the flow lines.
As a result, the gas temperature was obtained under operating conditions and in the
transitory state, which allowed to identifying the point where there is a higher probability
of hydrate formation. For the pipe with the least conductive material, the temperature of
the gas was determined in the case of a shutdown. In addition, the flow patterns were
determined both for the horizontal section (fog-annular type) and for the ascending
vertical section (annular type). This was validated with the free software DWSIM.

In the case of the thermal demand for central heating system and domestic hot water (DHW), the implementation of a solar thermal system for a 90 m2 four-inhabitant single-family house was proposed. For the location of this solar installation, a maximum 9 m2 on-rooftop area was available.
Additionally, the design of a solar thermal system for heating a 40 m2 recreational pool was proposed. Hence, two alternatives were proposed: one for an outdoor pool; and another for an indoor pool. In both cases, the energy required to heat the pool water would be covered entirely by solar thermal collectors (there would be no auxiliary boiler/heating system) located on the pool filter system room’s roof.
Regarding the covering of a percentage of the electricity consumption, the Ecuadorian Government is willing to subsidize the construction of an on-grid solar park if it covers 30 % of the annual electricity demand of the aforementioned housing estate and if it guarantees a 30-year operation. This facility must be situated within a 5 km radius from the housing estate, must consider land use (cannot be built on top of pre-existing structures nor within protected areas) and availability of roads and electricity networks, and must employ at least 30 % of female labor. Moreover, the photovoltaic power station must use conventional components and fixed structures with ballast and must not be anchored.
Also, this subsidy takes in account the construction of a self-consumption isolated photovoltaic installation which supplies electricity to a work booth that will be managing the bigger photovoltaic plant.
